Rajshree Group is one of India's foremost turnkey suppliers of Effluent Treatment Plants (ETP) for the pulp and paper industry. Our ETPs treat mill effluent through primary, secondary, and tertiary stages to meet CPCB/SPCB discharge norms.
In 2015 we installed a complete three-stage effluent treatment plant for a paper mill in Tanzania that met strict discharge norms. Since 2003, Rajshree Group has delivered 22+ pulp and paper projects across three continents — India, Africa and the Middle East — totalling over 2,000 TPD of installed capacity.

Paper Mill Effluent Treatment: Meeting Compliance While Recovering Value
Pulp and paper mill effluent is characterised by high BOD (Biological Oxygen Demand), suspended solids, colour from lignin degradation products, and varying pH from process chemicals. Untreated, this effluent is among the most environmentally impactful in Indian industry — which is why CPCB and state pollution control boards apply strict discharge norms, with increasing enforcement actions against non-compliant mills.
Rajshree Group's three-stage effluent treatment plants are designed not merely to meet compliance thresholds but to treat to reuse quality wherever possible. Our primary stage removes 60–70% of suspended solids through bar screening, equalization, and primary clarification. Secondary biological treatment removes dissolved BOD/COD through activated sludge, MBBR (Moving Bed Biofilm Reactor), or UASB processes — selected based on effluent load and land area available.
Mills facing regulatory pressure toward Zero Liquid Discharge (ZLD) benefit from Rajshree's tertiary treatment add-ons — including multi-media filtration, activated carbon adsorption, and membrane systems — that produce treated water suitable for reuse in the wood yard, ETP recirculation, or non-contact cooling systems, dramatically reducing freshwater intake from rivers or groundwater.
All Rajshree ETP designs are verified against current CPCB General Standards for discharge to inland surface water (BOD ≤30 mg/L, SS ≤100 mg/L) and SPCB-specific norms for paper mills. We also design for anticipated tightening of colour and AOX norms in emerging-market regulatory frameworks across Africa and the Middle East.
