j~òòéá=fåàéåíçêë= Mazzei injectors (patented) are extremely efficient, compact differential pressure injection devices. Currently operating successfully in thousands of installations, worldwide, Mazzei injectors offer a reliable, accurate and economical method to inject virtually any liquid or gas substance into a pressurized fluid stream. Function - How Mazzei Injector Works When a pressurized operating (motive) fluid enters the injector inlet, it is constricted toward the injection chamber and changes into a high velocity jet stream. The increase in velocity through the injection chamber results in a decrease in pressure, thereby enabling an additive material to be drawn through the suction port and entrained into the motive stream. As the jet stream is diffused toward the injector outlet, its velocity is reduced and it is reconverted into pressure energy (but at a pressure level lower than injector inlet pressure). Mazzei injectors are extremely efficient. They operate over a wide range of pressures and require only a minimal pressure differential between the inlet and outlet sides to initiate a vacuum at the suction port. Advantages Molded from high quality thermoplastics with superior strength, high temperature capability, resistant to most chemicals. INLET No moving parts, low maintenance, trouble-free operation. Unique design allows maximum cavitation in the injection chamber, thereby providing instantaneous mixing. Ideally suited for continuous mixing functions, require no secondary blending devices. Initial cost and installation cost are low. Powered by the motive fluid, no external energy required for most installations. Available in a broad range of sizes, flows and injection capacities.

The majority of Mazzei injectors are highly efficient, requiring less than a 20% pressure differential to initiate a vacuum. Testing - Performance data and other technical information have been prepared from actual test results and are considered to be reliable. Mazzei Injector Corp., however, assumes no responsibility for the accuracy of performance information under varied field conditions. Testing - was conducted at an elevation of approximately 300 feet above sea level. Water temperature of both motive flow and liquid suction was approximately 60 F. Liquid (water) suction was measured at 0 lift. Instruments and gauges used to measure flows and pressures were of the highest quality available and calibrated to an accuracy of less than ± 2%.

cáäíéê=jéçá~=j=déåéê~ä=mêçééêíáéë=c=`çåçáíáçåë=ñçê=lééê~íáçå Activated Carbon A porous solid in powder, extrudate or granular form, produced from any base material which as a high percentage of carboneaous content, ie: wood, nut pits or shell, animal bone, hydrocarbon sludge, peat, lignite, bituminous coal and anthracite coal. Advantages: The porosity of activated carbon offers an extremely high surface area to volume mass ratio. 2.2 pounds at 1,000 square meters per gram, a good typical carbon, has about the same surface as 100 miles of two lane highway. Carbon absorbs organic compounds which produce taste, odor, color or toxicity. Reduces free chlorine. Anthracite Anthracite is low in ash and friability. The coal is cleaned (reduction in ash content), screened and classified to the proper sizes for water filtration purposes. Advantages: Versus silica and quartz sands and gravels are: longer runs between backwashes, higher flow rates without headloss, lower backwash water pressures and/or quantities, a greater utilization of the bed mass for filtration, and a volumetric higher surface area. Garnet A naturally hard, durable, high specific gravity mineral. Resistance to attrition means less loss of media and shutdown time. High specific gravity means more control during backwash and lower losses to drain. The angular shape provides more ability to filter and longer production runs. Manganese Greensand Black nodular granules of manganese-coated natural greensands - used for removing soluble iron and/or manganese as well as hydrogen sulfide. It must be either continuously or periodically regenerated with potassium permanganate. Magnesium Oxide (Corosex ) Has a high degree of activity and speed of correction, allowing high flow. Gravel Gravel is used as a support to keep smaller media out of the distribution system and to stop channeling of water. Minimum layers of 3 per size is suggested. A high proportion are rounded and tend toward a spherical shape. Sand 99% of the water purified in the world today is accomplished by passing the water through Rapid Sand Filters. Theoretically the upper layer of the bed performs the filtration, while the lower layers provide the necessary support and assist in the hydraulics involved during the backwash cycle. The chemical and physical properties are important. The media must be hard, not smooth, and free of soluble particles. Birm Under the proper conditions, no chemicals to purchase for maintenance. Regeneration not required. Iron removal efficiency is extremely high. Only periodic backwashing is required. Durable material with a long life and wide temperature range. Weighs only 45-60 lbs/cubic foot. Manganese removal ph is 8-9. Calcium Carbonate (Calcite ) (Slow dissolve, crushed marble) Acidic waters on contact slowly dissolve the calcium carbonate media to raise the ph which reduces the potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing and maintain high service rates. Depending on ph and service flow, the bed will have to be periodically added to as the dissolved calcium carbonate depletes. As the calcium carbonate neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter. Filter Ag Advantages: Less pressure loss than through most other media. Light weight requires lower backwash rates. High service rates. High dirt removal capacity. Reduced shipping cost due to light weight/cu. ft. Specifications for our most popular resins and filter media are included on the following pages. Please call if specifications for any other media are required. 83

^JRMMmI ^JURM=C=^JUSM=q~ååáå=oÉãçî~ä=oÉëáåë Ion Exchange Resins for the reversible removal of naturally occurring tannin organics (color bodies) in potable waters. Purolite A-500 P, A-850, and A-860 are strong base anion resins for tannin removal from potable waters. All resins are functionally the same. A-850 is a gel resin. A-500 P and A-860 are macroporous resins. Physically, the A-860 is a porous version of the A-850 gel. At times, one resin may be more effective than the others depending on the area of the country. The resins are rated for tannin removal at 2000 ppm - gallons per cubic foot. To determine the gallon volume that can be had per cubic foot, divide the figure of 2000 by ppm of tannins in the water. If only a fraction of a cubic foot is used, then the water produced will be this fraction of the volume. Service flow rate is 2-5 gpm per cubic foot. Pressure drop in psi per foot of resin depth is 0.18 x gpm per sq. ft. Backwash flow rate is 2-3 gpm per sq. ft. for a minimum backwash time of 20 minutes. An upper basket is recommended. Resin bead size is 16 to 50 US mesh. In field installations, the tannin removal resin can be put in as the top portion of the softener resin bed. In this type of installation, all backwash and regeneration conditions would be those specified for the tannin resin. This means modifying softener system by cutting backwash flow in half and doubling backwash time. Use smallest brine injector. Avoid overrunning the resin as it is sometimes difficult to clean up. Regenerate as needed and on the conservative side. Never exceed three days without a regeneration. All standard available resin cleaners will help and not harm the tannin removal resins. Iron should first be removed from water where it exceeds 1 to 2 ppm. If iron is in excess of this, then use salt with a built-in resin cleaner. The resin regenerates with salt. The regenerant level is 8 pounds of salt per cubic foot. The salt regenerant solution to the resin bed should be 8% plus and the contact time 30 minutes. A-850 is tested and certified by UL under ANSI/NSF 61 for materials only. 86

^JROMb=j~Åêçéçêçìë=píêçåÖ=_~ëÉ=^åáçå=bñÅÜ~åÖÉ=oÉëáå Product Description Purolite A-520E is a macroporous strong base anion resin which is specially designed for the removal of nitrates from water for potable processes. The macroporous matrix and special ion exchange group functionality imparts ideal nitrate selectivity to Purolite A-520E, making this resin particularly suitable for nitrate removal even when moderate to high concentrations of sulfate are present. Hence this resin gives superior performance in nitrate removal applications when compared with standard exchange resins. A requirement of the nitrate removal process is to produce potable water meeting the quality standard defined by the European Economic Community in the Directive No. 80/778 of July 1980. This directive limits the nitrates to a maximum admissible concentration (M.A.C.) of 50 mg NO3/l. The USA drinking water regulations limit nitrates to 45 mg NO3/l. Regeneration Sodium chloride is generally preferred for regeneration for reasons of cost and efficiency. When available, sea water can be used quite effectively. The use of softened water for make up of regenerant and rinse is often recommended to avoid the precipitation of calcium carbonate in and around the Purolite A-520E (or any other resin used in this application). Although the precipitation is not particularly detrimental in the short term, the long term effects may include increased resin attrition and leakage of nitrates. Preconditioning Procedure Purolite A-520E is processed to ensure that it meets the requirements for use in the treatment of potable water. On installation, it is recommended that the resin be regenerated with two bed volumes of 6% NaCl followed by a rinse of four bed volumes of potable water, prior to use.

flk^` pojtp=^çî~ååéç=^åáçå=bñåü~åöé=oéëáå Superior Nitrate Removal for Treatment Plants & the Home Three Times the Selectivity and No Dumping IONAC SR-7 is an advanced anion ion exchange resin with more than three times the selectivity for nitrate ions than the best available commercial product. IONAC SR-7 reduces this widespread contaminant in municipal water. IONAC SR-7 has a new chemistry that prevents nitrate dumping against high sulfate backgrounds. In nitrate dumping, sulfate anions displace nitrate anions when resin capacity for nitrate is exhausted. Dumping can raise finished water nitrates well above the maximum contaminant level (MCL) set by the U.S. Environmental Protection Agency (EPA). IONAC SR-7 prevents dumping because it has a greater affinity for nitrate than sulfate, the reverse of other resins. The Nitrate Problem EPA s 1990 National Pesticide Survey estimated that 5% of public and private drinking water wells exceed the MCL for nitrates. This was also true of about 1,130 small water systems and 254,000 of the 10.5 million farm wells in the United States. The problem can occur anywhere, but especially in the Midwest, Northwest, along the Gulf Coast and in the Middle Atlantic states. Why Remove Nitrate? While nitrate itself is non-toxic, it is reduced to nitrite by bacteria in the stomach. Nitrite passing into the bloodstream can be taken up by hemoglobin, reducing the blood s ability to transport oxygen. Infants under six months of age are especially susceptible to this effect, causing the so-called blue baby syndrome. Others who may be affected include kidney dialysis patients, the elderly and those with compromised immune systems. Nitrates can also be converted in the stomach nitrosamines, proven carcinogens. Nitrate intake has been linked to cancer, but the evidence is not conclusive. An Extra Margin of Operating Safety SR-7 gives treatment plants and others an extra margin of operating safety by eliminating any possibility of nitrate dumping. The danger is that resin beds may run fully loaded if regeneration is delayed. This allows sulfate to displace nitrate on the resin. Plants without full-time operators are susceptible to this problem, as are homeowners who forget to regenerate on schedule. In all other respects, SR-7 operates well within normal operating conditions. It has been specially prepared to meet drinking water standards and has passed taste and odor tests.

flk^` j^`oljq IONAC MACRO-T is an acrylic strongly basic macroporous anion resin. Due to its acrylic structure, IONAC MACRO-T provides superior resistance to organic fouling. IONAC MACRO-T has the unique ability to remove tannins during the service cycle and release them during regeneration. This makes IONAC MACRO-T the resin of choice for residential water treatment systems where organic tannins are present. IONAC MACRO-T should be regenerated one time with a minimum of 10 lbs. NaCl/cu. ft. before its initial service cycle. This will reduce the potential for odor coming from the resin. Water containing 10 grains of hardness or greater should be softened prior to the tannin removal unit. Regenerations should be performed frequently to reduce the potential for organic fouling. Please refer to the Tannin Removal application bulletin for further guidelines or contact your Sybron Chemicals sales representative. IONAC MACRO-T can be used in layered bed systems.

altbu=e`o=`~íáçå=oéëáå An 8% cross-linked, high capacity resin for softening DOWEX* HCR resin is a high-capacity, gel-type, strong acid cation exchange resin with Gaussian (normal) particle size distribution. It is based on S-DVB (styrene-divinylbenzene) copolymer matrix with sulfonate functional groups. The degree of crosslinkage (approximately 8% DVB content) is chosen to yield a high-capacity, efficiently regenerable resin with good physical and oxidative stability for operation in typical non-aggressive softeners. For more highly oxidative systems, such as those containing 1 ppm Cl2, gel resins with higher levels of cross-linkage are recommended. The Gaussian particle size distribution of DOWEX HCR resin (ranging between 16 and 50 mesh) provides pressure drop that is sufficient to permit good distribution of flow across the resin bed. Backwash expansion characteristics allow for clean-up by bed fluidization. DOWEX HCR cation resin is available in the sodium form.

Inversand Company j~åö~åéëé=dêééåë~åç General Manganese greensand, used for removing soluble iron and/or manganese as well as hydrogen sulfide from well water supplies, is a purple-black filter media processed from Glauconitic greensand. Manganese greensand can be used in a completely closed pressure system with no aeration or repumping or in an open gravity filter system. The two methods of operation are continuous regeneration (CR), which is recommended for predominately iron waters and intermittent regeneration (IR), which is recommended for predominantly manganese waters.

Inversand Company j~åö~åéëé=dêééåë~åç Methods of Operation Continuous Regeneration (CR) Continuous regeneration (CR) operation is recommended on well waters where iron removal is the main objective with or without the presence of manganese. Briefly, it involves the feeding of a predetermined amount of potassium permanganate (KMnO4) usually in combination with chlorine (CI2) directly to the raw water prior to the unit containing manganese greensand. The chlorine should be fed upstream of the KMnO4 with a contact time of 10-20 seconds, if possible. Sufficient chlorine should be fed to produce desired residual in the filter effluent. The quantity of CI2 and KMnO4 required can be estimated as follows: ppm CI2 = ppm Fe ppm KMnO4 = 0.2 x ppm Fe + 2 x ppm Mn Without the CI2, the KMnO4 demand can be estimated as follows: ppm KMnO4 = 1 x ppm Fe + 2 x ppm Mn Suggested Operating Conditions Backwash - Sufficient rate to product approximately 40% bed expansion Capacity - 500 to 700 grains/sq. ft. bed area based on potassium permanganate demand. In addition to the manganese greensand, a 15 inch minimum specially sized anthracite bed is required. In any case, the pressure drop should not exceed 10 to 12 psi. Flow Rate - Normal flow rates with CR operation are 2 to 5 gpm/sq. ft. Higher concentrations of iron and manganese usually require lower flow rates for equivalent run lengths. Rates in excess of 5 gpm/sq. ft. can usually be tolerated, but a pilot unit should be operated to determine the effluent quality and run length. The run length between backwashes can be estimated as follows: Example: What is a run length on water containing 1.7 ppm iron and 0.3 ppm manganese at a 4 gpm/sq. ft. operating rate? KMnO4 demand = (Fe) 1.7 x 1 + (Mn) 0.3 x 2 or 2.3 ppm 2.3/17.1 = 0.13 grains/gal. (gpg) 700 grains/sq. ft. divided by 0.13 gpg = 5200 gal./sq. ft. 5200 gal./sq. ft. divided by 4 gpm/sq. ft. = 1300 min. Therefore, the backwash frequency is approximately every 20 to 24 hours of operation. Intermittent Regeneration (IR) The IR method of operation is recommended on well waters where only manganese or manganese with small amounts of iron is to be removed. Briefly, it involves the regeneration of manganese greensand with a predetermined amount of KMnO4 after a specified quantity of water has been processed. With this method, the pressure drop is lower because the manganese is removed by contact oxidation on the manganese greensand. This eventually results in a larger manganese greensand grain size and bed growth, which, if not tolerable, should be removed physically by backwashing at a higher rate or by sluicing from the bottom of the bed via suitable tank connection. Suggested Operating Conditions Backwash Rate - Sufficient to produce approximately 40% bed expansion Regeneration KMnO4 Dosage 1.5 to 2.0 oz. KMnO4 cu. ft. KMnO4 Solution strength 2 to 4 oz./gallon KMnO4 Regeneration rate 0.25 gpm/cu. ft. KMnO4 Regeneration time 30 minutes optimum KMnO4 Regeneration volume 7.5 gal/cu. ft Rinse rate 1 gpm/cu. ft. Rinse volume 40 gal./cu. ft. or until all traces of KMnO4 are gone Note: Recycle of rinse water will conserve KMnO4 and rinse waste water. Capacity - 300 grains Mn/cu. ft. Prechlorination is recommended, especially if iron is present. Pressure Drop - Maximum pressure drop 12 psi. If this pressure differential is reached before the capacity for Mn is obtained, manganese greensand can be backwashed without regenerating. Flow Rate - 2 to 5 gpm/sq. ft., or 1 to 2 gpm/cu. ft. For higher flow rates, contact supplier. 96

Inversand Company j~åö~åéëé=dêééåë~åç General Notes Raw waters having a ph of 6.2 or higher can be passed through manganese greensand without ph correction; waters having a ph lower than 6.2 should be ph corrected to 6.2 to 6.5 before passing through the manganese greensand. If a ph higher than 6.5 is desired in the water system, the additional alkali should be added after the filters, due to the adverse reaction (formation of a colloid) that sometimes occurs with the iron and alkali with ph over 6.5 KMnO4 Solution Strength - With CR operation, the KMnO4 can be any concentration up to 4 oz./gal. See chart for solubility of KMnO4. Solubility of KMnO4 in Water Temp F Temp C g/100 ml lb/gal 32 0 2.78 0.23 68 20 6.51 0.54 104 40 12.53 1.05 Warranty The information and recommendations in this publication are true and reliable to the best of our knowledge. They are offered in good faith, but without warranty or liability for consequential damage because the conditions and method of use of our products are varied and beyond our control. We suggest that the suitability and performance of our products be determined by the user before they are adopted on a commercial scale. Notice - The use of manganese greensand in the CR (continuous regeneration) process is covered by Patent No. 3, 167,506 but license to use the CR process is granted by a royalty charge of 25 cents per cubic foot at the time of purchase. Special Notes Removing Fines - although the manganese greensand is thoroughly washed before shipment, it is recommended that, before it is put into service, the material be thoroughly backwashed and the top layer of finer material be removed by undercutting. This is especially important if anthracite is placed on top of the manganese greensand. Each bag contains sufficient material to compensate for removing about 1 of finer material. Regeneration - Although the manganese greensand is thoroughly regenerated before shipment, it is necessary prior to use to regenerate with potassium permanganate solution contacting the bed for approximately 1 hour. Usually 2 oz. of potassium permanganate per cubic foot is adequate. The filter must be rinsed of all traces of permanganate after regeneration. Sometimes during the IR regeneration, more or less than the equivalent amount of potassium permanganate is required. Since this is an oxidationreduction reaction, if there are other reducing substances in the water, more permanganate than the equivalent amount may be required. Conversely, where there are oxidizing substances in the water such as oxygen and/or chlorine, under certain situations less potassium permanganate may be required. This can best be determined by close surveillance of operating data. Theoretically 300 grains of manganese is equivalent to 1.3 oz. of potassium permanganate. Permanganate Detector - A properly operated manganese greensand filter should never have potassium permanganate or pink water in the treated water supply. If, however, if is felt that insurance against pink water should be provided, there are detectors available to signal an alarm or shut down a plant should pink water be detected in the treated water supply. Further details are available from your equipment supplier. 97

j~öåéëáìã=lñáçé=c=`~äåáìã=`~êäçå~íé Magnesium Oxide Magnesium oxide is a specially processed hard, beadlike magnesia, adapted for use in filters to neutralize acidity by increasing the ph value. By neutralizing the free carbon-dioxide in water, magnesium oxide can correct red water conditions and render them to a noncorrosive condition. Magnesium oxide is used most effectively where ph correction is substantial or high flow conditions are in use. Magnesium oxide, being soluble to acidity, will have to be replenished periodically. Please note - under certain low flow conditions, magnesium oxide may overcorrect and create a basic condition. Magnesium oxide can be effectively combined with calcium carbonate to combine the high flow neutralization properties of magnesium oxide along with the slow reacting low flow properties of calcium carbonate without getting potentially high basic properties due to over correction.

Downflow service is satisfactory on waters with a hardness of less than 5 gpg or where it is combined with calcium carbonate at least 50/50.

Backwash frequently to prevent cementing. 6. Backwash bed expansion - 35%. 7. Service rate - 5 to 6 gpm but may be modified to adapt to local conditions. Calcium Carbonate (ph Neutralizer) Calcium carbonate is a crushed and screened white marble material which can neutralize acidic or low ph waters to a neutral non-corrosive affluent, inexpensively. Acidic waters, on contact, slowly dissolve the calcium carbonate media to raise the ph, which effectively neutralizes the potential leaching of copper and other metals found in typical plumbing systems. Periodic backwashing will prevent packing and maintain high service rates. Depending on ph and service flow, the media bed will have to be periodically added to as the dissolved media depletes. As the calcium carbonate neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.
