　　Wastewater from cleaning and degreasing of workpieces in a certain factory

　　The degreasing wastewater from the cleaning of workpieces in a certain factory contains not only the chemicals required for oil containing cleaning processes, but also oil stains, flocs, and other substances from workpiece cleaning. The water temperature of wastewater is generally 60 ℃, with a high pH value. The wastewater needs to be replaced periodically for 1-3 days, and the cost of replacing reagents is high, making it difficult to dispose of. The 0.1 micron hollow plate ceramic membrane can effectively retain solid suspended solids, oils, and flocs in the cleaning water, while allowing the effective components in the cleaning solution to pass through the membrane pores without affecting the effectiveness of reusing the cleaning solution.
