Wastewater treatment for paper manufacture and paper mills, and Case Studies

The pulp and paper industry is a typical water-intensive industry that requires large amounts of water. Inevitably, it also requires a large amount of wastewater and has large-scale treatment facilities.
Wastewater treatment technology and waste reduction efforts are also advanced, with some mills, for example, equipped with sludge-fired boilers and other zero-discharge facilities.

Wastewater from paper mills includes pulp wastewater, bleaching wastewater, and papermaking wastewater. And the volume of wastewater is large.
In the textile industry, a large amount of surfactants are used, and these are discharged as sewage, therefore it is important to biodegrade them in wastewater treatment.

Wastewater treatment for paper manufacture and paper mills, and Case Studies

Paper wastewater is generally treated by coagulation and sedimentation to remove solids such as fine fibers and additives in the white water, and the treated water is filtered and reused or circulated as washing water or dilution water.
Other pulp and bleach wastewater is treated by coagulation sedimentation or biological treatment, followed by a combination of coagulation sedimentation or pressure flotation and biological treatment.
Each plant and wastewater system often has its own wastewater characteristics, and the suitability of chemicals may differ for each individual wastewater.
It is important to deal with wastewater fluctuations in a detailed manner.

Recommended Products
Each plant and wastewater system often has its own wastewater characteristics, and the suitability of chemicals may differ for each individual wastewater.
It is important to deal with wastewater fluctuations in a detailed manner.
For paper manufacturing, we recommend the nonionic/anionic ACCOFLOC series and the cationic ARONFLOC series.
