Automatic filter has a wide range of applications. It is very popular in the industry in recent years. At the same time, automatic filter is also an essential water filtration equipment in many industries. It also plays a great role in the treatment of petrochemical wastewater, greatly solves the problem of wastewater treatment for enterprises, and is trusted by enterprises.
With the development of petrochemical industry, its water consumption and wastewater discharge increase. In order to alleviate the shortage of water resources, people are encouraged to use full-automatic filters for advanced treatment of sewage. The use of full-automatic filters not only saves water sources, but also reduces the discharge of pollutants and reduces the pressure of pollutants on the environment. The circulating cooling water of petrochemical enterprises in China accounts for about 70% ~ 80% of the total petrochemical water consumption.
During the circulating use of cooling water, the water quality continues to deteriorate, resulting in scaling or corrosion of equipment. In order to prevent scaling, the current method is to add a large number of chemical agents such as corrosion inhibitor and scale inhibitor to the circulating water, which can not fundamentally solve various problems caused by salt and organic matter concentration, and the treatment cost of adding various agents is high, which is easy to produce new pollution. The full-automatic filter is used to treat the sewage discharged from circulating water, which can effectively improve the concentration multiple, reduce the fresh water consumption of circulating water and reduce sewage discharge.
The full-automatic filter is a precision equipment that directly intercepts impurities in the water by using the wedge wire filter screen, removes suspended solids and particles in the water body, reduces turbidity, purifies the water quality and reduces the generation of system dirt, bacteria, algae and rust, so as to purify the water quality and protect the normal operation of other equipment in the system. The water enters the self-cleaning filter body from the water inlet. Due to the intelligent (PLC, PAC) design, The system can automatically identify the degree of impurity deposition and send a signal to the blowdown valve for automatic blowdown.
The birth of full-automatic filter can be said to have brought benefits to many industries. The full-automatic filter has been greatly improved on the traditional filter, not only the performance has been greatly improved, but also the use is more convenient. The use of automatic filter in petrochemical industry is a very correct choice. It helps the petrochemical industry greatly save water and promote the development of petrochemical economy.
