Hawach membrane filter is a poly-nuclear membrane composed of tens of thousands of micropores. Through membrane filter, particles larger than the aperture are filtered onto the surface. It is used to filter various solutions, remove bacteria and impurities. Also, the membrane filter is a critical part of the syringe filter and has different parameters and types.
Types of Membrane Filter
Basically, according to the shape of the membrane filter, membrane filter can fall into 2 major types: flat membrane and curly membrane. The flat membrane filter is mainly domestic film, including MCE, Nylon, PTFE, MCE，PES, CA, PVDF, GF，PP. \ For curly membrane filter, we can see there are imported and of homemade in the market. The imported mainly includes Nylon，PTFE, PTFE-L, MCE, PES, CA, PVDF and GF; Nylon，PTFE, PTFE-L, MCE, PES, CA, PVDF and PP.brands are produced locally.

Classification of filter membranes
Filter membranes are classified according to the size of retained raw water particles, and the pores of the membranes are divided into microfiltration membrane (MF), ultrafiltration membrane (UF), nanofiltration membrane (NF) and reverse osmosis membrane (RO). MF membrane has a pore diameter of 0.05um or more or molecular weight of 1,000 or more. It is intended to remove colloids and polymer organic matter.
The NF membrane has a pore size of 100 to 1,000 molecular weight. It removes substances between UF and RO to remove trihalomethane, odor, color, pesticides, soluble organics, Ca, Mg, etc. The RO separation particle size is tens of molecular weights, and the object is to remove common salts and inorganic salts.
