Waste Water Treatment Chemicals
Polyacrylamide is a kind of soluble high molecular weight polymer. Having several polar groups in the molecular chain, it can form bridge among particles by absorbing suspended solid particles in wastewater and condense particle into big flocs by neutralizing charges. Therefore, it can speed up sedimentation of particles in suspensions and excels in speeding up purification of solutions and promoting filtration and so on.
Flocculants used in all ranges of water problems like raw water, process water and effluent treatment etc. Water contains many soluble, insoluble impurities, turbid in nature affects subsequent operations. It is necessary to remove the maximum quantities of impurities with suitable chemical treatment. Flocculant has been developed to improve the settling rate with minimum sludge volume. These products are very effective over wide range of pH and has great flexibility in coping with fluctuation in operating conditions with their remarkable settling properties they rapidly bring down clarifier sludge levels under control when `difficult` process waters are treated.
Strong ionic group radical and activated-adsorbent group radical which can destabilize and flocculate the suspended solids and the negative-charged water-soluble matters in the waste water through electro-neutralization and bridging adsorption. It is very effective in flocculating, decoloring, killing algae and removing organics. With small dosages, this product can cause big flocs, rapid precipitation and low turbidity residue, and it can also produce small amount of sludge.
Industrial effluents can be very highly coloured. This colouring is created by colloids (pigments, sulphides) or by dissolved matter (organic matter, nitrated derivatives). Polymerized liquid organic coagulant which not only acts as a coagulant but is highly effective for the color removal in water & waste water clarification. The unique ingredients present in the product precipitates all types of colors generated in the effluent. Specifically, the textile effluent which contains colored matter due to the presence of different colored dyes.
Hydrogen Sulfide (H2S) can be a component of process gases dissolved in water and hydrocarbons during oil and gas operations. It is toxic, corrosive and, at high concentrations, can be extremely hazardous and lethal.

Foam can be a problem in many water treatment applications as well as in various production processes. On-site testing is an important tool for analyzing our customer’s needs and recommending the best products for their systems. Defoamers prevent generation of foams and causes existing foams to rapidly collapse. Srivilas’ series of defoamers are either Silicon based, non-silicones based or Fatty acid based. Silicones’ low surface tension and interfacial properties, combined with their lack of foam-stabilization properties cause the foam wall to thin and collapse. Fatty acid based defoamers are a composition of a polyether surfactant and a polyhydric alcohol fatty acid ester.
