In recent days, Mr. Liu, the head of a chemical enterprise in Shandong Province, China, has faced a crucial task of treating and recycling wastewater. The primary component of the wastewater is ammonium nitrate, with a low pH and moderate concentration. Mr. Liu urgently requires the use of highly efficient cleaning filters to remove impurities from the wastewater, ensuring compliance with environmental standards.
The specific requirements for wastewater treatment are as follows: the wastewater needs to be filtered to a particle size below 5 microns. To achieve more efficient filtration, Mr. Liu has implemented a membrane filter at the front end of the treatment system, effectively removing particles larger than 10 microns.
The designed flow rate for this treatment system is 25 cubic meters per hour. To ensure the stability and reliability of the system, Mr. Liu has opted for an advanced cleaning filter. This filter not only efficiently filters out tiny particles but also meets the high-flow processing demands.
To maintain the performance of the filter, Mr. Liu employs periodic backwashing operations using ammonia water for cleaning. This method not only clears captured waste but also ensures the longevity and filtering effectiveness of the filter.
Another noteworthy aspect is that the filtered residue is soluble in approximately 5% ammonia water. To fully utilize this characteristic, Mr. Liu plans to collect and further process these residues, ensuring a more environmentally friendly and sustainable wastewater treatment process.
Throughout the entire wastewater treatment process, Mr. Liu consistently focuses on adhering to environmental standards and regulations. He fully recognizes that efficient wastewater treatment not only ensures the normal operation of the enterprise but also contributes positively to environmental protection.
This case highlights the importance of considering factors such as wastewater composition, treatment requirements, and equipment performance when dealing with chemical wastewater. Through thoughtful design and operation, Mr. Liu has successfully achieved the high-efficiency filtration of wastewater, making a positive contribution to the sustainable development of the enterprise and environmental conservation efforts.
