ETP and STP chemical programs for effluent treatment and compliance.
Meeting discharge norms while controlling treatment cost is the central challenge of every effluent and sewage plant. Drashti Chemicals supplies complete wastewater treatment programs for ETPs and STPs — coagulants, flocculants, pH adjusters, defoamers and colour-removal chemistry — engineered to hit CPCB discharge limits reliably. Serving textile, chemical-manufacturing and food-processing plants since 2015 from Vadodara, we help operators clarify effluent, dewater sludge and remove colour and COD without over-dosing. Industrial effluent varies enormously in load, colour and salt content, so we start with jar tests and pilot trials on your actual wastewater to lock in the correct coagulant-flocculant combination. Our program spans primary coagulation with Poly Aluminium Chloride or ferric chloride, flocculation and sludge dewatering with anionic and cationic polyelectrolytes, foam control with defoamers, and colour polishing for dye-house streams. Every chemical ships with COA and MSDS, and our technical team supports dose optimisation and process reviews to reduce sludge volume, improve dewatering and cut your total treatment cost while keeping the plant compliant.
Wastewater treatment moves through primary, secondary and tertiary stages. Primary coagulation with PAC or ferric chloride destabilises suspended solids and colloids; flocculation with anionic or cationic polyelectrolyte then agglomerates them for clarification. pH correction with lime or caustic keeps coagulation in the optimal band. Biological or chemical secondary treatment reduces BOD/COD, while defoamers control foam in aeration and equalisation tanks. Tertiary polishing removes residual colour and fine solids, and polyelectrolyte-dosed dewatering conditions the sludge. Drashti supplies coagulants, flocculants, pH chemicals and defoamers across this full chain.
Drashti Chemicals brings jar-test and pilot support to every ETP and STP program, not just chemical supply. Serving textile, chemical and food-processing effluent plants since 2015 from Vadodara, we provide coagulants, polyelectrolytes, defoamers and colour-removal chemistry with COA and MSDS. Our dose-optimisation and process-review services reduce sludge volume, improve dewatering and lower treatment cost, backed by bulk supply contracts and fast dispatch across Gujarat and India.
Common ETP chemicals include coagulants such as PAC and ferric chloride, flocculants like anionic and cationic polyelectrolytes, pH adjusters, defoamers and colour-removal agents. Drashti Chemicals supplies all of these with jar-test support.
Cationic polyelectrolytes condition sludge so it releases water more readily in centrifuges and filter presses, producing a drier cake, reducing disposal volume and lowering handling cost.
Yes. We conduct jar tests and process reviews on your actual effluent to fine-tune coagulant and flocculant dosing, cutting chemical spend while maintaining compliance.
Colour is removed through a combination of coagulation with PAC or ferric chloride, flocculation and specialty colour-removal agents, selected based on the dye chemistry present in the effluent.
Yes. We supply from bag quantities to bulk loads with COA and MSDS, plus bulk supply contracts and fast dispatch from Vadodara across India.
