Water & Effluent Treatment

Water & Effluent Treatment — bulk supply from Ahmedabad.

Coagulants, polyelectrolytes, biocides, antiscalants and disinfection chemistry for municipal works, ETPs and CETPs, RO plants and cooling systems. Dose rates always come from a jar test on your own water — anyone quoting a dose without seeing the stream is guessing.

Questions

Water & Effluent Treatment — what buyers ask us.

What chemicals are used in an ETP?

An effluent treatment plant typically uses: coagulantspoly aluminium chloride, ferric alum, alum; flocculants — anionic and cationic polyelectrolyte; pH correction — lime, caustic soda and acids; disinfection — sodium hypochlorite, TCCA, SDIC; plus defoamer and activated carbon. The right list depends on your effluent — share the analysis and we will match products to it.

Do you supply boiler and cooling water treatment chemicals?

Yes — oxygen scavenger and corrosion inhibitor for boilers and cooling systems, biocides (glutaraldehyde, isothiazolinone), antiscalant and membrane cleaners for RO plants. Dosing programmes should be set by your water-treatment consultant.

Are you water treatment chemical manufacturers?

We are a bulk supplier, not a formulator. Products are sourced from qualified Indian manufacturers and supplied by tanker, drum and bag.
