Wastewater from the pulp and paper industry can be difficult to treat. Netsol Water industrial water treatment systems are specifically built to address these issues, in highly economical and energy-efficient methods. We offer specialised, dependable water and wastewater treatment solutions, for pulp and paper manufacturing facilities that are low-cost, low-energy, and adhere to tight environmental regulations as specified by CPCB.
Characteristics of paper and pulp mill effluent
Effluent solids, sediments, absorbable organic halides (AOX), chlorinated organic compounds, and contaminants with high chemical and biological oxygen demands (COD and BOD), are among the contaminants that are naturally present in P&P waste streams.
Experts in the field estimate that 85% of the water used in the P&P sector is utilised as process water. As a result, there are significant amounts of contaminated water that must be treated on-site. Treatment alternatives include primary treatment, such as clarifying to removing solids and particulates, and secondary biological treatment techniques to remove biodegradable organic waste, and lessen the toxicity of the effluent.

Need of clean water in paper and pulp mills
The paper industry uses a lot of water, and at several points along the manufacturing process, clean water is a must. An efficient management of water treatment is required for this. Any modern pulp facility must generally treat a variety of waste water streams from operations, like bleaching, washing, emptying, and evaporation condensates.
At Netsol Water, we help paper makers and manufacturers boost efficiency, and address the environmental difficulties of today's more cutthroat market. Our services range from wastewater treatment to water reuse and recycling.
Water Treatment Solutions for Pulp & Paper Industry
· Plant for Reverse Osmosis (RO System)
· Effluent Treatment Plant

In order to further improve the quality of effluent water, tertiary treatment techniques can be used. These include membrane filtering, ion exchange, and granular activated carbon.
Reusing water in paper and pulp industries
More industrial enterprises are looking into water recycling within facilities, as a way to minimize wastewater discharge volumes due to increasing water shortages, and increased awareness of water conservation.
The most efficient methods for processing water so that it may be used at the start of a process, are membrane technologies like reverse osmosis, microfiltration, ultrafiltration, and nanofiltration. Additionally, recycling is made simpler by carefully selecting the chemicals used to treatment water. For instance, using ozone instead of chlorine removes long-term residue, and lessens the wastewater's corrosive effect on the membranes.
Conclusion
These factors are encouraging P&P plant operators to convert from traditional water treatment to membrane systems, along with corporate responsibility initiatives to reduce water usage.
