SunDec – Decolorant / Colour Removal Polymer Supplier in Ahmedabad

Dye makers at Vatva and Naroda and textile processors at Narol discharge intensely coloured effluent. SunDec binds dissolved dye for the CETP inlet.

Dye making is a colour problem

The city makes the dyes and intermediates and also processes the fabric they colour, so both ends of the colour chain sit in one place. A dye-making unit sends out effluent that can be acidic or alkaline, deeply coloured and heavy in COD and dissolved salts.

Because each batch differs, an equalisation tank ahead of the train does a great deal of the work.

How the train runs

Neutralisation and coagulation remove much of the suspended matter. What coagulation leaves behind is dissolved dye, and SunDec SC05 turns that into particles. A cationic grade, Sunfloc Cationic HQ, then pulls the particles into heavy flocs for the primary clarifier. The strongest streams may go through Fenton oxidation or evaporation before they reach this train.

Iron sludge left by Fenton oxidation is a separate settling problem, and an anionic grade suits it.

Narol, CETPs and the Gujarat board

Narol's processing houses send pre-treated effluent to common plants that set inlet limits for pH, COD, colour and suspended solids. A unit stays inside those limits by treating consistently, writing down each dose and jar-testing the equalisation tank on a schedule. The Gujarat Pollution Control Board regulates units. About four to five days by road from Chennai; see our Ahmedabad CETP guide.

SunDec questions from Ahmedabad

Can SunDec treat very strong dye-maker effluent directly?

Strong streams are usually segregated, stripped or oxidised first. SunDec works on the pre-treated stream's remaining colour.

Does it replace coagulant?

No. Coagulation comes first. SunDec binds the dissolved dye.

How far ahead should I order?

Allow four to five days for road freight, and add a margin for the batch schedule at your unit.

Dye-maker colour loads

Dye intermediates give very strong colour, so jar-test on the actual stream before you set a pump.
