GREASOLUX – a product providing solutions to problems caused by fat in wastewater treatment 2GREASOLUX – a product providing solu-tions to problems caused by fat in waste-water treatment Industrial and municipal waste contaminated with fat – a frequent problem for companies maintaining waste-water network infrastructure and municipal wastewater treatment facilities. We recommend the use of GREASOLUX fat dissolvent cartridges to avoid the problems of pipeline chocking, equip-ment damage, offensive odors, formation of filamentous bacteria, poor wastewater treatment results, poor sedimental properties of activated sludge. GREASOLUX – is a cartridge that slowly dissolves in water, enriched with special fat dissolvent microorganisms and enzymes. GREASOLUX – is an especially efficient product for low cost solutions to problems caused by fat: only few strategically placed cartridges will remove or minimize the problems caused by fat. GREASOLUX efficiency lies in the special cartridge structure containing especially powerful fat dissolving mi-croorganisms and enzymes. When the cartridges dissolve slowly, microorganisms will spread all over the wastewater system (pipelines, vessels, etc.) and consolidate on various surfaces. Thereby such conditionally small amount of mi-croorganisms initiates growth of large bacterial colonies, which are able to dissolve large amounts of fat efficiently. GREASOLUX is simple to use: just drop the cartridges in the correct locations and then replace them regularly every one or two months.Sizes of GREASOLUX cartridgesGREASOLUX cartridges are cylindrical, coated with a special protective layer and placed into a plastic net for suitable hanging in vessels. Water - easily contacts the prod-uct through the mesh gradually dissolving the cylinder. GREASOLUX cartridges come in two standard sizes: Greasolux-M and Greasolux-L. The cartridges differ by solubility and content of microorganisms and active agents (Table 1).If necessary, GREASOLUX cartridges can be custom made (bigger or smaller) or placed in special water perme-able containers to increase or decrease the life of cartridge. Dosing programWhereas the major component of GREASOLUX is microorganisms able to generate in proper conditions, the product dosage (the number of suspended cartridges) can-not accurately be determined and depends on site circum-stances. You can follow the guidelines provided below to select a proper dose. Later this can be modified to obtain the optimum results. GREASOLUX has the most effective action when it is suspended as close as possible to the problem area, i.e. if a municipal wastewater treatment company has problems caused by fat, so it would be perfect to hang GREASOLUX cartridges in wastewater system of the company which generates fats (fat collectors, compensation tanks or pump houses). For the purpose of its effect improvement it is rea-sonable to suspend additional GREASOLUX cartridge in wastewater line before the municipal treatment facility, for example, in a pump house pumping the wastewater to treat-ment facility or in wastewater acceptance-quenching tank. Furthermore, one shall avoid hanging of GREASOLUX cartridges in aggressive medium: high wastewater tempera-ture, contact with concentrated chemical agents (for exam-ple, detergents), acute pH fluctuations. In pump stations the cartridges shall not be placed in the wastewater flow.

Samples of GREASOLUX cartridgesGREASOLUX – a product providing solutions to problems caused by fat in wastewater treatment 3Moreover, the products should be suspended to such a depth, so to ensure continuous contact with water, but shall not lie on the bottom. The number and size of cartridges usually is selected ac-cording to wastewater amount and degree of wastewater con-tamination with fats. It is reasonable to place GREASOLUX in the same wastewater line in different points (Table 2). Below you can find estimated GREASOLUX doses for wastewater pump houses, wastewater acceptance tanks and fat collectors.Also it is reasonable to use GREASOLUX in wastewa-ter collection wells, in case of choking of pipes. In such case it is reasonable to place one GREASOLUX-M cartridge in a well beside the choked points. The major effect can be achieved, if you hang the product just right after physical cleaning of pipelines.Table 2Greasolux-M and Greasolux-L dosing program for fat collectors Wastewater flowFat collector volumeAverage number of dishes per day The amount of fat stored in the collector Greasolux quantity in the collectorUp to 1 l/s Up to 0,5 m3 Up to 100 20 kg M – 1 pcs.1-4 l/s 0,5-1,5 m3 100-400 20-60 kg M – 1-2 pcs.4-7 l/s 1,5-3 m3 400-600 70-100 kg L – 1-2 pcs.7-10 l/s 3-5 m3 60-1000 100-150 kg L – 2-3 pcs.Over 10 l/s Over 5 m3 Over 1000 Over 150 kg L – 4 pcs. and moreTable 3Greasolux dosing program for wastewater pump houses, compensation tanksWastewater flow rate in a pump house Greasolux quantity0-1000 m3/day M – 1 pcs.1000-2000 m3/day L – 1 pcs.2000-3000 m3/day L – 3 pcs.3000-5000 m3/day L – 4 pcs.5000-10 000 m3/day L – 5 pcs.10 00 -20 000 m3/day L – 6 pcs.Over 20 000 m3/day L – 6-10 pcs.Control GREASOLUX doses in a certain situation • Food processing company equipped with primary treatment facility or without it. Wastewater amount: 100-1000 m3 per day. Fat content in wastewater fluctuates from 100 to 1000 mg/l. Dose: from 3 to 6 GREASOLUX-L cartridges in different places of wastewater line (see the control schemes). The cartridges shall be replaced once per one or two months. • A cafeteria equipped with a fat collector of 1 m3 capacity and 10 m3 of wastewater per day. Dose: one GREASOLUX-M cartridge placed in a fat collector and replaced once per two months. • Shopping center having a culinary shop. Wastewater is collected by two fat collectors of 1 m3 capacity. Wastewa-ter amount – 30 m3 per day. Dose: two GREASOLUX-M cartridges, one cartridge to each collector. Shall be replaced one or two months. GREASOLUX – a product providing solutions to problems caused by fat in wastewater treatment 4If the wastewater treatment facility is treats wastewater from several pump stations the correct quantity of GREA-SOLUX cartridges shall be placed in each pump station. The quantity of GREASOLUX cartridges is estimated, in every certain case the quantity can be bigger or smaller, de-pending of wastewater specificity, contamination or expect-ed results. To obtain better results several cartridges can be placed in the same line, for example in the industrial shop channel, where wastewater is collected by a fat collector, in a fat collector and pump station. Possible examples of lay out of cartridges are provided in the schemes. At first it is always recommended to use greater num-ber of GREASOLUX cartridges and after receipt of the expected result – the number of cartridges can be gradu-ally reduced. However, it is highly important to place new cartridges regularly (every 1-2 months). Furthermore, at the beginning it is recommended to fix dissolution of car-tridges in certain places: if the cartridge dissolution term is less than two weeks or remains undissolved for more than 3 months, in such points it is necessary to change the layout of cartridges. If it is impossible to change the lay out, please contact the GREASOLUX supplier. Fig. 2.
