In modern industrial production, the generation of corrosive waste liquid is an inevitable by - product, posing significant challenges to both environmental protection and resource utilization. In this context, ceramic membranes have emerged as a highly effective solution for corrosive waste liquid recovery.

Ceramic membranes are typically made from inorganic materials such as alumina, zirconia, and titania. These materials endow the membranes with remarkable properties such as chemical stability and high mechanical strength, which enables them to withstand the harsh corrosion of waste liquids containing strong acids, alkalis, or other corrosive substances.
The working principle of ceramic membranes in waste liquid recovery mainly relies on crossflow membrane separation technology. When the corrosive waste liquid passes through the filter, the membrane acts as a selective barrier with nanometer pore size. Acid & alkali liquid,and small molecules of valuable substances can easily pass through the pores of the membrane, while oil, larger molecules, suspended solids are retained. The clean filtrate or valueable retentate can be recycled again.
There are several advantages of using microfiltration and ultrafiltration ceramic membranes in corrosive waste liquid recovery. One major advantage is their high separation efficiency. They can achieve a high degree of separation of different components in the waste liquid, which greatly improves the purity of the recovered substances. Additionally, ceramic membranes are relatively easy to clean and maintain. Their stable chemical properties allow for the use of various cleaning methods without being easily damaged. Moreover, compared with some traditional waste liquid treatment methods, the use of inorganic membranes can significantly reduce energy consumption and chemical reagent usage, which is beneficial for cost - control and environmental protection.
The membrane filtration machine can be made in anticorrosion material like carbon steel lined with plastic, FRPP, PVC, or even Titanium and Hastelloy alloy.
