1 General Environmental Science Core Capabilities August 6, 2012 The following is a summary of core GES technologies as they apply to significant market segments. Wastewater Treatment Sludge Reduction in Activated Sludge and Lagoons Description: This technology applies only where secondary biological treatment is used. Sludge reduction does not apply where non-biological treatment is used or where primary treatment is used exclusively. Range of Benefits: In activated sludge systems, sludge reduction occurs for the amount of Waste Activated Sludge (WAS) produced per lb of BOD or COD removed. Percent reduction may range from 15 to 35%. Larger reductions are found in systems with longer retention times (24 hours or more) and more concentrated influent wastewater. In lagoon systems with sludge build up on the bottom, the blanket will be reduced by 20% to 50%. Products Required. Generally, sludge reduction will require use of LLMO S1 and LLMO Activator. For sludge reduction, a bioreactor is nearly always required. A typical bioreactor would be a 55-gallon drum, equipped with temperature control (a submersible heater of 100 to 300 watts with room temperature setting) plus diffused air supplied by either plant air or an auxiliary air pump. Larger bioreactors are used for larger treatment plants. Examples of Prime Treatment Situations. This application is very successful when sludge dewatering and disposal costs are very high. The savings from reduced sludge production generally more than offset the cost of LLMO product, with excess savings retained by the authorities. This application is especially attractive when landfill space is at a premium. Industrial treatment plants, especially meat, dairy, and food processing, that meet the conditions noted above are particularly good candidates for sludge reduction Examples of Poor Candidates. Sludge reduction is not applicable in short retention time systems (4 hours or less). Presence of anaerobic digestion generally makes our system uneconomical. Effluent Improvement in Activated Sludge and Lagoons Description: This technology applies only where secondary biological treatment is used. Effluent improvement does not apply where non-biological treatment is used or where primary treatment is used exclusively. Range of Benefits: In activated sludge systems, Effluent improvement to permit level requirement is generally possible. This technology applies to both BOD and NH3 reduction. In general, it does not apply to phosphate reduction. Products Required. Generally, BOD effluent improvement will require use of LLMO E1 and LLMO Activator. Reducing effluent ammonia will require StartSmart and possibly StartSmart Activator. For effluent improvement, a bioreactor is nearly always required.

2 A typical bioreactor would be a 55-gallon drum, equipped with temperature control (a submersible heater of 100 to 300 watts with room temperature setting) plus diffused air supplied by either plant air or an auxiliary air pump. Larger bioreactors are used for larger treatment plants. Examples of Prime Treatment Situations. For BOD reduction, this application is very successful when there is significant industrial waste of a colloidal nature. This application is especially attractive when a treatment plant exceeds its design capacity either in organic loading or hydraulic loading. For nitrification, the application is nearly always successful when the treatment plant partially meets nitrification requirements, but needs assistance to finish the job. Examples of Poor Candidates. When high effluent BOD is due to insufficient secondary clarifier capacity, the application is not likely to succeed. NOTE: We can apply our technology to treatment plants where organic and/or hydraulic loading exceeds design capacity. However, we will not participate in the design of new wastewater treatment plants. Grease and Sulfide Reduction in Sewer Collection Systems and Grease Traps Description: This technology is used in sewer collection systems where grease build up is common. Examples include wet wells, sewer lines downstream for restaurants, etc. Range of Benefits: Proper use of this technology can eliminate manual removal of grease from wet wells and lift stations. Odor control in and around lift stations will reduce complaints from local residences, and will reduce loss of concrete from crown corrosion. When applied to grease traps, grease pumping can be reduced 50% or more. Products Required. Most commonly, GelPac G or GelPac LS are used for these applications. GelPac G requires a small bioreactor system. GelPac LS includes an attached tether, and does not require a bioreactor. For a given treatment situation, consult with GES to determine which product to use. Examples of Prime Treatment Situations. Restaurant grease traps are excellent candidates for treatment, especially when odor problems are common. Wet wells and lift stations downstream from grease and fat generators often require treatment for proper operation. Examples of Poor Candidates. GelPacs generally continue to function well with normal fluctuations in water temperature, ph, etc. However, when particularly large amounts of cleaning chemicals or severe water temperature or ph changes occur, the GelPac performance may be impaired. Septic Tank Treatment Description: Septic tanks that service individual household or larger septic tanks (serving office complexes, apartment buildings, restauarants, etc) have certain problems that can be solved with GES septic tank products. Excess sludge pumping can be reduced, odor problems can be solved, sluggish drain field can be restored to free flow.

3 Range of Benefits: Excess pumping can be reduced 50%, foul septic system odors will be eliminated, and sluggish drain field will be restored to free flow conditions. Products Required. GES markets retail style septic tank additives: Flush and Drain Free. Flush and Drain Free do not have a sulfide product odor, and are therefore better accepted in households. LLMO products (S1 and G1 in particular) can be used for septic tank treatment, particularly industrial septic systems. However, the sulfide odor present in LLMO S1 and G1 generally make them less suitable for use in household septic systems. Examples of Prime Treatment Situations. All septic systems are reasonable candidates for product use. Household cleaning chemicals, disposal of pills and drugs harm septic systems. And even hot water can upset the functioning of a septic tank. Flush and Drain Free (as well as LLMO S1 and G1) restore the required biomass to a healthy level. Dosing is generally performed every 30 to 90 days. Examples of Poor Candidates. When the drain field is plugged due to inorganic blockage, tree roots, etc., GES products will not be effective and a new drain field may be required. Lake and Pond Treatment Description: This application is for reducing excess algae in lakes and ponds, and for reducing foul ponds odors. This technology works by restoring a proper balance between algae and bacteria in a lake or pond. GES does not use any algaecides or toxic chemicals in its products. Range of Benefits: Foul odors are generally eliminated within 2 to 4 weeks of first product application. Excess algae.blooms are reduced within 2 weeks to 2 months of first product application, depending on the severity of problems. Products Required. GES provides both retail style and commercial grade products for lake and pond restoration. For sales through retail outlets, GES trade names are PondFlush and PondPerfect. For mid sized applications (1 to 10 acres), GES offers ComboPacks (a combination of liquid PondPerfect concentrate plus slow release, powder based EcoSocks). For large applications, GES uses a mix of LLMO products along with delivery systems (bioreactors). Examples of Prime Treatment Situations. Sales of retail pond treatment products is strong in many countries throughout the world, and marketing outlets include on-line stores, garden centers, and hardware stores. Mid sized applications include lake and ponds found on government properties, industrial complexes, and homeowner associations. Large lakes include eutrophic lakes of all types with surface area greater than 10 acres. Examples of Poor Candidates. Rapidly flowing water with short retention time (less than 7 days) is difficult to treat. GES products works well when algae is the problem. Other aquatic nuisances such as duckweed are problematic, and are not typically solved with our product line. Otherwise, nearly any pond can be beautified with safe, natural, GES products.

4 Aquarium Products Description: GES works with its sister company, TLC Products in Cleveland, Ohio, to offer aquarium additives (StartSmart bacterial products). StartSmart is sold in over 1000 retail shops in the USA, and is increasing its presence internationally as well.. Range of Benefits: StartSmart Complete, available in both freshwater and saltwater formulas, is independently proven to instantly cycle an aquarium. It also controls algae problems in aquariums, and is great for routine maintenance. Products Required. Freshwater and saltwater versions of StartSmart are available. Product sizes include 4 oz, 12 oz, and 32 oz bottles, plus one gallon bottles and 4 gallon pails. Examples of Prime Treatment Situations. Anyone setting up a new aquarium should use StartSmart Complete. The product is also ideal for reducing algae problems and for routine maintenance (maintaining water clarity, reducing sludge, etc). The product sells well on-line, and in physical pet supply stores. Examples of Poor Candidates. As long as the product is used in aquariums according to directions, StartSmart Complete is beneficial to all aquariums. Commercial Aquculture Description: GES uses its LLMO products, for commercial aquaculture, and also works with its sister company, TLC Products in Cleveland, Ohio, to offer aquaculture additives (StartSmart bacterial products). StartSmart has been evaluated by the prestigious College of Fisheries (India, Mangalore) and proves to be uniquely powerful at reducing toxic ammonia and sludge in commercial aquaculture. Range of Benefits: StartSmart, available in both freshwater and saltwater formulas, is independently proven to eliminate toxic ammonia in commercial aquaculture. It also controls algae problems in fish ponds, and can be used to minimize sludge, eliminate sulfides, and reduce off flavor. The greatest benefit of LLMO or StartSmart use is reduced fish mortality and improved crop yields. Products Required. For sludge reduction, preferred products are LLMO S1. For larger ponds, LLMO S1, LLMO Activator, and a Delivery System are recommended. For reduced ammonia and nitrite, StartSmart is preferred. For large systems, StartSmart, StartSmart Activator, and a Delivery System are used. Examples of Prime Treatment Situations. Commercial aquaculture is generally identified as extensive, semi-intensive, and intensive. Our products are particularly helpful in semi-intensive and intensive aquaculture, where higher fish stock density is accompanied by more sludge and ammonia problems. In extensive systems, our products are generally used for reducing algae blooms rather than sludge or ammonia. Examples of Poor Candidates. In our experience, any semi-intensive or intensive aquaculture system is a good candidate for our products. Extensive systems are good candidates only when algae problems exist.. Agicultural Lagoons Description: Agricultural lagoons include hot pits and cattle pits. These manure pits suffer from inpenetrable surface crusting, which makes land application problematic.

5 And these systems often have odor problems that draw complaints from surrounding residences and businesses. LLMO products are useful in reducing both problems. Range of Benefits: LLMO AG, in both ready to use bottles and with a bioreactor configuration for larger projects, solve both common problems. Crusting is reduced (but not eliminated) so that the manure slurry remains pumpable. Also, odors are abated, though not eliminated. Use of LLMO AG according to directions will reduce the complaints registered by local residents and businesses.. Products Required. For smaller hog and cattle manure pits, Ready-To-Use LLMO AG is applied. For larger systems, LLMO AG is mixed with Activator in a bioreactor before it is applied to the pits.. Examples of Prime Treatment Situations. LLMO AG is very successfully sold through farm co-ops to small farms. This is done extensively in Europe. In the USA, telemarketing firms successfully sell LLMO AG to small farmers. Examples of Poor Candidates. Generally, mega-farms have not been good candidates for product use, as they have their own treatment systems (actual wastewater treatment plants, rather than primitive pits). LLMO AG is specifically intended for manure storage pits. To enhance a wastewater treatment plant that treats animal manure waste, use standard LLMO products as discussed elsewhere in this document... Specialty Applications Description: In our long history, GES has been successful in a wide variety of specialty applications. Please note that the following list is not comprehensive, but is intended to provide an idea of other areas where LLMO use can be of assistance... Phenol reduction Reducing hydrocarbon contamination in soils Compost pile accelerant Odor reduction via topical spray to poulty processing plants Specialty industrial treatment such as palm oil, pulp and paper plants, food processing of all types Odor control in boat and recreational vehicle waste tanks Floor and carpet cleaning formulas For case studies, more technical information, or general questions about GES programs, please contact Euromarket ltd at: sales@euromarket.com.gr
