Waste Water Treatment Solutions in Pulp and Paper Industry
The pulp and paper industry generates significant volumes of wastewater during various stages of the production process. The wastewater contains organic compounds, suspended solids, and chemicals used in pulp bleaching and papermaking. Proper wastewater treatment is essential to meet environmental regulations, minimize the environmental impact, and recycle water for sustainable operations.
Implementing a combination of these wastewater treatment solutions tailored to the specific characteristics of the pulp and paper industry effluents helps achieve regulatory compliance and promotes sustainable water management practices. The choice of treatment depends on factors such as the type of pulp processing, chemical usage, and the desired effluent quality.
Water Treatment in the Pulp and Paper Industry
The separation of solids from the effluents is accomplished with help of screens, grid chambers and settling tanks. Screens are units which operate according to the sieving/filtration process. The function of the screens is to remove coarse, bulky and fibrous components from the effluents. The grit separating systems currently in use are subdivided into longitudinal grit traps, circular grit traps and vortex grit traps, depending on their design and process layout.
