Advanced Water & Wastewater Treatment Solutions for the Paper & Pulp Industry
Integrated water management systems for sustainable paper manufacturing from raw water to Zero Liquid Discharge.
Critical Challenges in Paper & Pulp Water Management
The paper and pulp industry faces complex water management challenges that demand specialized treatment approaches.
Water-Intensive Manufacturing
Water fundamental in every phase from pulping raw materials to final paper finishing processes, serving as medium for fiber transport, chemical distribution, and temperature control.
Complex Wastewater Characteristics
High BOD (lignin, carbohydrates, volatile acids), high COD from bleaching, suspended solids (fiber particles, fillers like kaolin, calcium carbonate, bark), color and lignin compounds.
Toxic Substance Management
AOX (adsorbable organic halides), resin and fatty acids, sulfur compounds requiring specialized treatment approaches.
Process Variability Challenges
pH and temperature variability with extreme discharge values affecting treatment system stability.
Environmental Compliance Pressure
Stringent regulations requiring advanced treatment for discharge or Zero Liquid Discharge implementation.
Production Consistency Requirements
Water quality directly impacts paper sheet structure, coating processes, and final product quality.

| Process Stage | Core Design Features | Operating Window | Guaranteed KPI |
|---|---|---|---|
| Raw Water Treatment Plant | Removal systems for suspended solids, turbidity, hardness | Engineered for process stability | Improved water clarity, reduced scaling and fouling |
| Primary Treatment | Screening and Dissolved Air Flotation (DAF) systems | Initial solids and oil/grease removal | Protects downstream biological processes |
| Secondary Treatment | Biological oxidation using activated sludge or Membrane Bioreactors (MBR) | Effective organic load reduction | High BOD/COD removal efficiency |
| Tertiary Treatment | Filtration and clarification systems | Further polishing stage | Meets discharge or reuse standards |
| Advanced/ZLD Systems | Zero Liquid Discharge or high-efficiency water reuse systems | Complete water recovery | Reduced environmental impact, freshwater conservation |
| Demineralization (DM) Plant | Resin-based systems with optional RO integration | Chemical preparation, bleaching, coating applications | Eliminates trace dissolved minerals |
