Wastewater and polymer in India: key figures
The numbers behind India's treatment gap, and why flocculant demand keeps growing. Each figure carries its original source.
Installed treatment capacity covers about 31,841 MLD, and roughly 20,235 MLD gets treated.

Barely one litre in four of India's sewage is treated today, so treatment plants of every kind are still being built. Every one of them needs a flocculant for clarification and a polymer for sludge dewatering. Anionic grades already make up almost half the polyacrylamide market. Use the grade selector and the dosing calculator to plan your own plant's needs.
