Water Treatment Chemicals

Srish chem has the proprietary technologies needed for cost effective water treatment including recycling and recovery.Our water conservation solutions are being used by major industries such as Pharma,Textile,Paper, Paints,Chemicals and Dairy.Water optimization is a critical component of all modern establishments given the urgent need to save and recover water.We have the technologies coupled with know- how and experience to provide customized waste water treatment solutions and green utilities that deliver renewable,recycling and recovery solutions.There are several levels of waste water treatment,these are primary,secondary and tertiary levels of treatment.Different treatment stages or combinations are adopted dependent on the original quality of the water and it’s intended final uses.

Effluent treatment process & required chemicals

Primary treatment
The primary level of treatment uses screen and settling tanks to remove the majority of solids,during primary treatment waste water is temporarily held in a settling tank where heavier solids sink to the bottom while lighter solids float to the surface.This step is extremely important,because solids make up approximately 60 percent of the pollutants that must be removed

Coagulants
Coagulants and flocculants process are used to remove colloidal impurities, suspended particles such as bacteria ,clay, slits and organic matter from the contaminated water. The process large flock aggregates that can be removed from water in subsequent clarifaction/filtration process.There have been various machanism proposed for the coagulation process that mainly incorporate double layer suppression,adsorption and charge neutralization,adsorption and intra particle bridging and enmeshment or sweep flocculation.

Since a priori selection of coagulants for any particular waste water is not possible on the basis of theoretical analysis,it is imperative that selection be made using an empirical approach through a set of experiments performed on various coagulants and under different processing conditions

Alkalines:-
Calcium hydroxide,Caustic soda,Sodium silicate

Acidic
Ferrous sulphate,Ferric Chloride,Alum,PAC,
Polyclean,Clean All A,SSE Floc CR

Most of the Companies are using Lime & ferrous sulphate as coagulants,Now so many companies are using polymer base chemicals,it is very advance technology and much better than ferrous sulphate & lime
