The filter is an essential filter element in sewage treatment.In recent years, the situation of water pollution has been intensifying, which has caused the sewage treatment and regeneration industry to receive unprecedented attention. In order to make the sewage meet the water quality requirements for draining a certain water body or re-use, it is purified.Anping Chunyu Wire Mesh Products Factory has been specializing in the production of filters for 15 years. It has cooperated with various domestic environmental protection water treatment plants to design and develop various forms of sewage treatment filters and filter cartridges, which have been well received by customers.We have also accumulated a wealth of experience in the production process.Which material is used most in environmentally friendly water treatment?

There are many water filters made of stainless steel. Stainless steel materials are divided into many types according to different chemical elements. 304 materials and 316L materials are mostly used in water treatment.

304 material stainless steel filter features: There are three common marking methods on the market: 06Cr19Ni10, 304, and SUS304. Among them, 06Cr19Ni10 generally represents national standard production, 304 generally represents ASTM standard production, and SUS304 marks Japanese standard production.The general use temperature limit is less than 650℃.304 stainless steel has excellent stainless and corrosion resistance and good resistance to intergranular corrosion.For oxidizing acids, it was concluded in the experiment that 304 stainless steel mesh has strong corrosion resistance in ****** below the boiling temperature with a concentration of ≤65%.It also has good corrosion resistance to alkali solutions and most organic and inorganic acids.Generally refers to "18-8" (18% chromium, 8% nickel), most of which are basic stainless steel alloys, which are very suitable for mesh.It can be exposed to the outdoors and will not rust or be oxidized when the external temperature rises to 1400 degrees Fahrenheit.

316L stainless steel filter material characteristics: In addition to having better corrosion resistance and ductility than 304 stainless steel, and high temperature resistance, it is less susceptible to corrosion in brine, sulfur water or brine than other chromium-nickel stainless steel.
