With the rapid development of industrialization, a large amount of industrial wastewater needs to be effectively treated to reduce the negative impact on the environment. As an efficient and environmentally friendly separation technology, microfiltration membranes play an increasingly important role in industrial wastewater treatment.
Microfiltration membrane is a kind of filtration membrane with a surface pore size at the micron level, which can intercept impurities such as suspended solids, bacteria, and organic matter, and realize the separation of water and impurities. Microfiltration membranes have the following characteristics:
High filtration accuracy: the pore size range of the microfiltration membrane is 0Between 1-10 microns, it can effectively intercept impurities such as suspended solids, bacteria, and organic matter in the water.
Low filtration resistance: The pore size of the microfiltration membrane is large and not easy to clog, which can effectively reduce the filtration resistance and improve the filtration efficiency.
Environmentally friendly and pollution-free: The microfiltration membrane adopts the physical separation method, which does not need to add chemical reagents and will not produce secondary pollution.
Easy to maintain: The microfiltration membrane can be cleaned and maintained by backwashing, chemical cleaning, etc., and is easy to operate.
Application of microfiltration membranes in industrial wastewater treatment.
Petrochemical wastewater treatment: Petrochemical wastewater contains a large number of suspended solids, oily substances and organic pollutants, and the use of microfiltration membrane can efficiently intercept these impurities and realize the purification of wastewater.
Pharmaceutical wastewater treatment: Pharmaceutical wastewater contains a large number of harmful substances such as antibiotics, drug residues and microorganisms, and the use of microfiltration membranes can effectively remove these substances and meet the discharge standards.
Food processing wastewater treatment: Food processing wastewater contains a large amount of suspended solids, proteins, oils and other organic matter, and the use of microfiltration membrane can efficiently remove these impurities and purify the wastewater.
Electroplating wastewater treatment: electroplating wastewater contains harmful substances such as heavy metal ions and organic matter, and the use of microfiltration membrane can intercept these substances to achieve wastewater purification.
