Introduction to the processing principles of oil removal filters

　　The filter element is the heart of the oil removal filter. It is used to purify the original ecological resources and the reuse of resources. The purification equipment needed to remove a small amount of impurities in the filter medium can protect the normal operation of the equipment or the cleanness of the air. After the oil filter has a certain accuracy of the filter element, its impurities are blocked, and the clean fluid flows out through the filter element.
　　The water quality treated by the oil removal filter has reached the wastewater discharge standard stipulated by the state, effectively protecting the environment. Moreover, the water quality treated by the oil removal filter can be reused to effectively save water energy, and the effective pollution control ability of the oil removal filter has been well received by people.
　　The purpose of water treatment and control of oil removal filter is mainly to solve the problems of corrosion, scaling and microbial slime in water treatment. In practical applications, it is necessary to test and evaluate the corrosion, scaling and microbial conditions and the effects of the agents used.There are many test and evaluation methods for oil filters. In addition to individual test methods, there must be a comprehensive test method. When determining the formulation of water treatment agents, three test steps are generally adopted: screening test, evaluation test and medium-sized simulation test. On-site monitoring should also be carried out after the formulation is tried, and then the effect of the agent should be judged.
　　The principles followed in the treatment of industrial wastewater by deoiling filters:
　　1. Organic wastewater like urban sewage, such as food processing wastewater, sugar wastewater, and papermaking wastewater, can be discharged into the urban sewage system for treatment.
　　2. Prioritize the use of non-toxic production technology to replace or reform backward production technology, as far as possible to eliminate or reduce the production of toxic and harmful wastewater in the production process.
　　3. Wastewater containing highly toxic substances, such as wastewater containing some heavy metals, radioactive materials, high concentration phenol, and cyanide, should be diverted from other wastewater to facilitate the treatment and recovery of useful substances.
　　4. During the use of toxic raw materials and the production of toxic intermediate products and products, strict operation and supervision should be performed to eliminate dripping and reduce losses, and reasonable processes and equipment should be used as much as possible.
　　5. Wastewater with large flow rate and light pollution should be properly treated and recycled, and should not be discharged into the sewer, so as not to increase the urban sewage and urban sewage treatment load.
