Pulp & Paper

Challenges include handling highly variable and toxic effluent streams, removing recalcitrant organics, color, and solids, and recovering water for reuse with minimal energy and chemical inputs. Sustainable water management solutions are vital to reduce operational costs and environmental impact while fostering circular economy practices.

Sarvo’s Solution Approach

Sarvo delivers advanced and customized water and wastewater treatment technologies tailored to the pulp and paper industry’s unique requirements. Our integrated treatment trains utilize physical, chemical, and biological processes including coagulation-flocculation, sedimentation, and advanced biological reactors such as Membrane Bioreactors (MBR) for efficient BOD and COD reduction.

We deploy ultrafiltration (UF) and reverse osmosis (RO) membrane systems for polishing treated water to meet reuse quality standards, reducing dependency on fresh water sources. For stringent regulatory and sustainability goals, Sarvo offers energy-efficient Mechanical Vapor Recompression (MVR) evaporators complemented by sludge drying technologies to achieve Zero Liquid Discharge (ZLD).

Our solutions feature automation with AI-based controls to optimize operations, reduce energy consumption, and ensure compliance. Modular and scalable designs allow seamless integration and future expansions with minimal disruptions.

Customer Case Study: Mohini Health & Hygiene Ltd, Indore

Sarvo commissioned a turnkey wastewater treatment plant for Mohini Health & Hygiene Ltd, a pulp and paper-related textile processor in Indore. The facility addresses high volumes of wastewater highly contaminated with suspended solids, organic loads, and color originating from mercerization and finishing processes.

The system incorporates Membrane Bioreactor (MBR) technology for robust organic removal, along with Ultrafiltration (UF) and Reverse Osmosis (RO) systems for recycling and water quality polishing. Sarvo’s Mechanical Vapor Recompression (MVR) evaporator concentrates RO reject to reduce wastewater volume while enabling recovery of approximately 90% process water through condensate reuse. Concentrated sludge is processed via drying to produce safe, disposable solids.

This integrated, automated solution facilitates regulatory compliance, supports water conservation goals, and lowers operational costs, exemplifying Sarvo’s expertise in sustainable water solutions for pulp and paper industry challenges.
