Belagavi sugar mill and distillery effluent: a guide
How sugar mills, distilleries and foundries around Belagavi treat their wastewater through the crushing season, and which polymer suits each stream.
A seasonal load
Most mills in the district crush cane for a few months after the monsoon, so effluent volume and strength rise sharply in season and fall away afterwards. Plants that sit idle for months need to check stored polymer and restart their treatment steadily rather than all at once.
Sugar mill effluent
Mill effluent carries cane wash water, floor washings, boiling-house spills and cooling water. It is high in suspended solids and sugars. After screening and oil removal, an anionic grade such as Anionic HQ clarifies the wash water and the primary settling tank.
Distillery spent wash
Spent wash from molasses distilleries is dark, acidic and very high in organic load. It is usually handled through biomethanation, concentration and composting or incineration rather than discharge. In the clarification steps that remain, cationic grades such as Cationic HQ and the liquid SunMac SC04 do most of the work.
Foundry water around Udyambag
Foundries reuse water for sand washing and cooling. Fine sand, clay and metal particles settle much faster when a small dose of anionic polymer is added at the inlet of the settling pit, which keeps recirculated water clean.
Rules and records
Units in Belagavi are regulated by the Karnataka State Pollution Control Board. Keep the spec sheet, SDS and batch COA for each polymer on file, and log daily doses so you can show consistent treatment through the season.
Before the season starts
Run a jar test on last season's retained sample or the first week's effluent, confirm grade and dose, and order enough for the first month of crushing.
