SunDec – Decolorant / Colour Removal Polymer Supplier in Coimbatore
Mills that dye and finish yarn or fabric around Coimbatore discharge coloured, alkaline effluent. SunDec binds dye ahead of the cationic flocculant.
Mills toward Tiruppur
Textile mills spread out from Coimbatore toward Tiruppur, and many dye and finish yarn or fabric on site. Their effluent is coloured and alkaline, and it needs colour removal before discharge or reuse.
The polymers that suit a textile mill are different from the ones used by the foundries across town.
Documents for SunDec SC05
The usual order
Coagulation comes first, then SunDec SC05 for colour, then a cationic grade such as Sunfloc Cationic HQ to settle the combined floc. Skipping the middle step leaves a clarifier that settles solids nicely and still discharges coloured water.
Practicalities
Drums come up the Salem–Erode highway and are normally on site within a day or two. Water from the Siruvani and Pilloor schemes is usually clear, so most of the load in a mill comes from the process itself. The Tamil Nadu Pollution Control Board regulates units. Read our Coimbatore guide, and see SunMac for Coimbatore for machining coolants.
Mill shade changes
Keep a dose table by shade family, so the operator does not restart the jar test every time.
