Water Treatment Biocide

Water treatment biocide

Water treatment biocides are also known as algaecides, sludge dispersants, or anti-sludge. They are a class of chemical agents that can inhibit the growth of bacteria, algae, and microorganisms in water to prevent the formation of biological slime, which can cause to the system. This includes oxidizing biocides such as strong bromine, sodium hypochlorite, bleaching powder, ozone, chlorine tablets, etc; non-oxidizing biocides such as 1227, 1527, isothiazolinone, dimethyl sulfide, etc.; metal compounds such as mercuric oxide, mercuric chloride, mercuric fluoride, etc.; and slime biocides such as rosin amine hydrogen peroxide, biguanide polymers, etc.Water treatment biocides are a class of chemicals that can control the extension of bacteria and algae and prevent the production of slime and algal substances from causing harm to the system. Among them, quaternary ammonium salts are non-oxidizing biocides that are more popular now generally with multiple effects such as sterilization, dispersion, and corrosion inhibition, and are widely used in oilfield water, industrial cooling water, etc.Cleaning biidesThe main ingredients of American cleaning biocides are suitable for membrane element types and will not produce harmful substances that affect the operation of the system. A small amount of bi can meet the needs. Its use methods are:The first type, continuous dosing: before adding the biocide to the filter, the dosage should be increased or decreased according to the actual situation and intermittently injected; that is, it can reduce costs and effectively control bacterial reproduction.The second type, soaking; prepare a 1% concentration ofocide solution, use a pump to inject it into the dosing device, soak for an hour, and also extend or reduce the soaking time according to the degree of pollution of the; after soaking, it is necessary to flush the device with reverse osmosis product water or pure water for fifteen minutes.Note: Before soaking, you can first clean with acidic solution, which can remove residues on the surface. Then soak and wash with alkali to remove the corpses of organisms and organic residues.The third type circulating cleaning; prepare a 20% disinfection solution, and flush at low pressure for a time not less than an hour. Note that this method is not suitable forose acetate membrane elements.Due to the characteristics of soft water, it is often used for swimming pool water, so softening water agents and swimming pool water treatment chemicalsBoth can choose water treatment biocides to treat microorganisms and impurities in water;
