Papermaking wastewater recycling

Papermaking wastewater recycling

One way to save water is recycling. Includes waste water reuse. Waste water through depth treatment, then back to the usage of different processes, to achieve”zero emissions”, so estblishing waste water purification reuse system, improve industrial waste water reuse rate is an important measures to the paper industry water conservation. but also to achieve paper industry sustainable development. With waste water characteristics and recycle requirments, paper making waste water cycle reus, dicided into Whitewater direct reuse, indirect reuse, closed cycle.
Papermaking waste water closed cycle, it will gradually accumulate harmful substances and reach a very high concentrations, to affect the normal production of paper machine. These pollutants includes dissolved organic matter, salts, secondary stickies and anion garbage. They can cause resin content multiplied, clogging slurry pipeline, headbox, vacuum tank, vacuum rolls, affecting the normal production of paper machine. Toper Industrial Equipment Co. recommended effective treatment technology, wastewater treatment reach back to the water quality requirements. Wastewater treatment technology can be divided according to their physical method, chemical method, biochemical method, wherein the membrane separation is an effective treatment of papermaking wastewater reuse technology.
