Mr. Liu, the head of a chemical enterprise in Shandong Province, China, has added a new dimension to the company's environmental practices by successfully filtering wastewater using Zhongbang Precision Filters.
The key challenge in this wastewater treatment task was to address ammonium nitrate wastewater with a low pH and moderate concentration. Mr. Liu implemented a highly efficient wastewater treatment system, incorporating cleaning filters and membrane filters to ensure the effective removal of tiny particles and impurities from the wastewater.
With a designed flow rate of up to 25 cubic meters per hour for the wastewater treatment system, Mr. Liu chose an advanced cleaning filter to cope with the challenge of high flow rates. This filter not only maintains high-efficiency filtration but also extends the lifespan of the precision filter through periodic backwashing operations.
A crucial aspect of wastewater treatment is the backwashing operation, and Mr. Liu opted to use ammonia water for cleaning. This operation not only clears accumulated substances from the filter but also preserves the filter's performance.
On the other hand, the residues after filtration are soluble in approximately 5% ammonia water. Mr. Liu cleverly collects these residues, planning for further processing to minimize their environmental impact.
Through this successful wastewater treatment practice, Mr. Liu has not only provided a reliable solution for the company's production but has also made a positive contribution to environmental conservation in Shandong Province. This case once again highlights how companies, while pursuing economic benefits, actively fulfill their social responsibilities and are dedicated to advancing clean production and environmental conservation efforts.
