SunMac – Cationic Polymer Supplier in Kolkata
The Bantala leather complex treats salty, protein-rich effluent. SunMac, a liquid cationic polymer, supports coagulation ahead of the clarifier.
Tannery protein and the pH
Protein-rich effluent responds to SunMac when the pH is right, so check the pH before every jar test.
What tannery effluent carries
Beamhouse operations such as soaking, liming and unhairing give a salty, alkaline stream holding hair, protein, fat and sulphide, and chrome tanning brings trivalent chromium on top. Chrome-bearing liquors are best segregated for recovery so less chromium reaches the common plant.
The combined effluent is equalised, coagulated and clarified. Protein and fat respond to a cationic polymer.

SunMac in the primary step
SunMac SC04 neutralises the charge on fine and colloidal solids, and on protein-rich loads it can support the coagulant. A cationic Sunfloc grade then builds the heavy floc that settles. The same cationic chemistry conditions tannery sludge, which is bulky, so the press releases more water.
Our page on tannery effluent covers the wider process.
From Chennai to Howrah and Bantala
The West Bengal Pollution Control Board regulates units here. The coastal highway through Vijayawada, Visakhapatnam and Bhubaneswar is a long haul, so a margin of stock is wise.
SunMac questions from Kolkata
Does SunMac handle chromium?
Chrome-bearing streams are segregated and treated for recovery first. SunMac works on the combined effluent's solids afterwards.
Is it better than the powder grades?
They do different jobs. SunMac neutralises charge; a Sunfloc grade builds the floc. Many plants use both.
How is it supplied?
In drums, as a clear liquid, with a 24-month shelf life.
