Polyacrylamide gel

Polyacrylamide gel is used as a flotation reagent for the mining and mineral processing industry, treatment of water from industrial effluents, and drinking water preparation. Polyacrylamide gel PURPOSE: for water treatment. It is most widely used as a flocculant for effective purification of natural and wastewater, capture and separation of heavy metal ions and toxic substances, which helps solve environmental problems. The product is manufactured using traditional technology without the use of microorganisms. For flocculation: Polyacrylamide gel is also used for flocculation in the mining and chemical, coal, gas and oil production industries, ferrous and non-ferrous metallurgy, for pulp and paper and textile industry enterprises, and in the production of putties and water-emulsion paints.

Safety requirements: Not dangerous (non-flammable, non-explosive), hazard class 4. Storage: In closed warehouse premises at temperature not exceeding +35°C in closed containers to prevent drying out. Transportation: By all types of transport in accordance with cargo transportation rules applicable to the given type of transport, provided the product is protected from precipitation. Packaging: Non-returnable. P. e. containers 20…30 l. CONSUMPTION RATES AND FEATURES The polyacrylamide requirement for water treatment systems can be estimated based on the rate of 0.15 g/m³ of main substance content in the treated water. A working solution with a concentration of 0.1% of main substance content in water is prepared in advance. The gel is effective for treating heavily contaminated and turbid waters, as well as at low temperatures (around +4°C). Granular water-soluble polyacrylamides Polymers for processing plants, drilling operations, paper production, drinking water production, wastewater treatment. Polyacrylamides are classified depending on purpose into: anionic, cationic, nonionic, amphoteric, and with different molecular weights. Main application areas: -Enhanced Oil Recovery -Profile Control -Drilling Mud Additives to increase drilling mud viscosity and allow significant reduction of filtration losses of drilling mud and increase drilling productivity by 3-8. Due to reduced permeability of formations, wellbore wall stability also increases. The polymer can be used either independently or in combination with bentonite. During forced downtime, thanks to the thixotropic character of the drilling mud, the sludge will not settle. These polymers are effective for both fresh and seawater. -Shale Stabilization -Lost Circulation Control -Mining and Mineral Processing Industry for the following productions: coal, gold, silver, copper, lead, zinc, aluminum, uranium, titanium dioxide, nickel, phosphoric acid. -Paper Production -Wastewater Treatment
