Shandong Sun Paper succeeded in low-pressure membrane water purification

Shandong Sun Paper Co., Ltd. developed a low-pressure membrane water purification technology and it has been put into operation.

Reducing the impact of straw pulp wastewater on the environment and achieving “zero emission” of wastewater is a problem that Shandong Sun Paper has always solved. Not long ago, the company was the first in the paper industry to adopt the most advanced low-pressure membrane water purification technology in China to perform advanced treatment of straw pulp wastewater. This technology is a kind of physical water purification technology. It integrates the functions of separation, filtration, adsorption, etc. It has a one-time investment, a small area, a concise process, low operating costs, high degree of automation, easy operation and maintenance Features.

After the successful application of the technology, the COD of straw effluent can be reduced to less than 50mg/1, SS can be reduced to 10mg/or less, colorless, odorless, sterile, and no suspended matter. Second only to drinking water standard, 90% of wastewater can be used. Used for production.
