68 Nelsen Scale Prevention System Nelsen Scale Prevention Systems FILTERSORB-SP ANTI-SCALING SYSTEMS Nelsen Scale Prevention Systems features Filtersorb SP filter media to first remove the already existing scale from pipes and heat exchanger surfaces (descaling effect) and further to protect the system from future formation of scale (scale protection effect). Filtersorb SP is based on a completely new technology. In this process the chemical structure of scale forming minerals is changed. This technology is so effective that it requires a contact time of only seconds. The media is used in an up flow system, therefore only an in-out head is needed. The media transforms the dissolved calcium carbonate (temporary hardness) into non-charged, neutral chemical bonds. These bonds are completely stable and cannot attach to any surfaces. The chemical bonds are rinsed away by the water flow. The size of the bonds is so small (in the range of nano-meters) that they can only be seen with a microscope. Therefore the effect is the same as if the water was free of temporary hardness (calcium carbonate). The chemical structures are heat resistant and do not fall apart. The media is used to clean pipes from already existing scale and to protect pipes and hardware from scale. Tests with commercial coffee machines showed that those with FilterSorb-SP Hardness Stabilizer protection were much cleaner after a short time of use than the control systems which were cleaned monthly. Filtersorb SP works great in front of RO membranes. It keeps these membranes from clogging with calcium-carbonate. A preexisting membrane s efficiency is improved after only 10 days if calcium carbonate was the reason for the blocking.

AIR INJECTION OXIDIZING FILTER SYSTEM 5600AIO System TM Nelsen AIO Air Injection Oxidizing Filter System Nelsen AIO Air Injection Oxidizing Filter Systems The Nelsen AIO Air Injection Oxidizing Filter System, as a single tank system, is an efficient and cost effective system for the removal of iron and sulphur. The Nelsen AIO maintains an air pocket in the top of the tank while the system is in service. As the water passes thru the air pocket, iron and sulphur are oxidized. Additionally, dissolved oxygen is added to the water. The Nelsen AIO filter media bed then removes the iron and sulphur from the water. The Nelsen AIO can remove up to 8 ppm Hydrogen Sulfide and up to 7 ppm Iron. A daily backwash will remove accumulated iron and replenish the filter media bed. The regeneration process also adds a fresh air pocket to the system. The Nelsen AIO system comes equipped with either a Fleck 2510SXT or 5600SXT air injection control head that automatically backwashes the system daily to clean the media and flush everything down the drain.

Nelsen Arsenic Reduction Systems at the Core Nelsen Arsenic Reduction Systems with Layne at the Core Nelsen Arsenic Reduction Systems feature the Nelsen 7000PID Arsenic Redution Control Valve and LayneRT adsorption media. The 7000PID is a non-backwashing controller programed for the specific water chemistry for each installation. The controller indicates the capacity of system and the remaining safe levels of media adsorption. LayneRT is a proprietary, durable, arsenic selective media, developed as a significant improvement on the efficiency and longevity of traditional arsenic media. It is a reliable, high capacity technology that effectively reduces arsenic to safe levels without wasting any water or sending any waste water back into the environment through the drain. These systems are designed to reduce arsenic to less than 0.010 mg/l. (10 µg/l (ppb)). Actual performance of the system may vary depending on specific water chemistry and conditions at the consumer s installation. Following installation of this system, the installation site should have the treated water tested for arsenic to verify arsenic reduction is being achieved and the system is functioning properly. A full Arsenic Speciation Test Package (Arsenic Raw, Arsenic Treated, Iron, Manganese, ph, Sulfate o-phosphate, Silica, Vanadium) needs to be performed to properly treat and pre-treat the water. A variety of water parameters will effect the life of the media and some parameters will allow leaching of Arsenic through the system.

72 FreshPoint Ultrafiltration System, Up-Flow/Down-Flow Filters FreshPoint Ultrafiltration System The PENTEK FreshPoint Ultrafiltration System provides complete point-of-entry (POE) filtration proven to reduce turbidity, particulates and cysts for safer, cleaner water at every tap. The system employs hollow-fiber Ultrafiltration membrane technology to filter impurities as small as 0.025 microns. To maximize membrane capacity and service life, a metered flushing cycle is controlled using an advanced controller and high-performance turbine meter. The self-cleaning forward and backflush cycles are initiated when the programmed capacity of the membrane is reached. During the backwash, flow is reversed and particles are ejected from the pores of the membrane and flushed to drain. In the forward- flush cycle, service water passes through the capillaries at a high speed, scouring particles from the membrane surface and rinsing them from the system. Since power is only required to flush the system, outages and interruptions will not jeopardize the integrity of membrane or its ability to provide safer, cleaner water. The advanced electronic controller provides a programmable day override which allows the unit to flush every day with fresh water when the system is not in use. Critical system diagnostics, including totalized flow, instantaneous flow rate, and previous day s water usage, are available to optimize flushing cycles and monitor performance. The high-performance industrial fiberglass housing is pressure rated to 00 psi. Inside the housing, the membrane is sealed with double radial o-rings, minimizing the potential for leak paths. Quick-connect end caps allow the membrane to be easily removed for cleaning or replacement. The system can be applied to solve known water problems including high turbidity, suspended solids, and certain microbiological contaminants. It can also serve as a flushable pre-filter to extend the life of media filters downstream. Designed for cyst reduction, turbidity, and fine sediment filtration applications > 98% reduction of 0.025 micron (25 nanometer) particles* > 99.99% (> 4 Log) reduction of 0.065 micron (65 nanometer) particles* Forward-flush and back-flush cleaning cycles provide extended filter life in a wide range of applications Proprietary hollow-fiber ultrafiltration membrane Professional-grade housing, controller and flush valve Metered self-cleaning cycle flushes only when needed Day override feature flushes module daily with fresh water when system is not in use Peak flow rates up to 10 gpm (2271 L/h) *Performance based on MS-2 (25 nm) and PRD-1 (65 nm) virus particle tests.

Duke Aerator, Air Pump The Duke Aerator Aerators will reduce/remove unwanted odors, gasses, and VOC's from your water supply. The Duke aerator also reduces water borne radon which can be found in some water supplies. In conjunction with other radon reduction methods, aerators can be an effective alternative. The Duke aerator works on a simple process of spraying water through nozzles in a fine jet mist. As the water is spraying, it will naturally release the gas or odor. The gas is then vented to the outside using the assistance of a vent blower on indoor models, or naturally released to the atmosphere when using an outdoor aeration system. Aerators are a non-chemical alternative for reduction or removal of unwanted gasses or odors. The Duke Aerator tank is atmospheric and requires a pump and pressure tank to provide water pressure to the house or building. Included in each package are aerator tank, spray bar, solenoid valve with 115v float switch for solenoid valve, 20v safety float switch for aerator pump and 115 volt vent blower, drain pipe with ball valve and installation instructions.

76 Surface Water FAF-2000 FPFILTER SF-1500 Surface Water FLOATING FARM POND FILTER Since 1960, the Floating Pond Filter, consisting of a housing assembly and replaceable filter element, has proven to be the easiest and most economical way to remove clean water from ponds and lakes. When used in a well maintained pond within a controlled drainage area, a Floating Pond Filter provides the cleanest possible water for final filtration and disinfection through a household treatment system. FPFILTER Floating Farm Pond Filter $ 60.00 FLOATING CISTERN FILTER The only noticeable difference, between the cistern filter and the farm pond filter, is that the cistern filter removes water from closer to the surface. It also has a shorter stem length. FCFILTER Floating Cistern Filter $ 60.00 FLOATING FILTER ACCESSORIES FCHOSE 1-1/4 x 10 ft. Flex. Hose $ 127.00 FPELEMENT Replacement Element $ 16.00 FILTERING ROOFWASHER FOR RAIN WATER CISTERNS The filtering roofwasher collects rain water from downspouts, then filters it before it enters the cistern. The first rain to fall on a roof washes off dirt and debris which has accumulated since the last rain. As this first and dirtiest water enters the roof-washer, the larger debris is removed by screens in the leaf-catcher compartments. This first water, which never enters the cistern, is collected and held in the bottom quiet chamber. Once the quiet chamber fills, additional incoming water begins passing through the filter element and into the cistern. A small weep-hole in the overflow/clean-out pipe discards the dirty water and allows the quiet chamber to drain between rains. * SF-1500 Roof Washer, Single (For 1500 sq. ft. of Roof Area) $ 1,481.00 * SF-000 Roof Washer, Double (For 000 sq. ft. of Roof Area) $ 1,89.00 FLOATING AERATOR FOUNTAIN The Floating Aerator Fountain is designed for use in ponds, lakes or any other contained body of water with a minimum depth of 0".
