What is an inorganic ceramic membrane? What are the characteristics of inorganic ceramic membranes?

After years of development in the industry, membrane technology has a good performance in water treatment. However, there are still some problems to be solved, especially membrane fouling and membrane life. With the improvement of environmental protection standards, inorganic ceramic membrane technology has ushered in the spring of development.

The main components of oily washing wastewater from oil plant include saponin horn, oil, phospholipid, protein, colloid, pigment, etc. It usually comes from the production process of oil refining, fatty acid, margarine, mayonnaise and so on. It causes serious environmental pollution and can only be discharged after reaching the standard. The traditional process adopts "oil separation, flotation and biochemical treatment" to treat almost emulsified refining wastewater, which is difficult, complex operation and high cost. The application of membrane separation technology for fine pretreatment of wastewater will greatly reduce COD and oil content, not only reduce the burden of subsequent biochemical treatment, but also recover a large amount of waste oil and saponin, save operation cost and ensure that the discharge meets the standard.
