For membrane housing, we can provide you glass fiber reinforced plastic membrane housing (FRP), stainless steel membrane housing, and ceramic membrane housing. There are various models, and the models are different according to different functions. Mainly used in seawater desalination and sewage treatment.
RO and NF membrane shells are generally made of glass fiber reinforced plastic or stainless steel, because they have to withstand greater pressure. UF membrane shell is generally made of UPVC or ABS, because the operating pressure of ultrafiltration is generally low (generally less than 0.3Mpa).

What are the classifications of membrane shells?
Membrane shells are divided into eight-inch membrane shells (8040) and four-inch membrane shells (4040). The membrane shell has one core, two cores, three cores…seven cores. (8040, 8080, 80120…80280).
How many connection methods are there for FRP membrane shells?
There are two connection methods for FRP membrane shell :
2.5″ : End Port Connection
4″ : End Port Connection and Side Port Connection
8″ : End port connection and side port connection
What are the max working pressure for FRP membrane housing?
300PSI ,400PSI ,450PSI ,600PSI ,800PSI ,1000PSI ,1200PSI
What are the classifications of stainless steel membrane shells?
According to the sealing form of the end cover, it is divided into: clamp type, flange type, built-in type;
According to the water inlet method, it is divided into: end inlet and side inlet.
What are the technical characteristics of stainless steel membrane shell?
Pressure resistance: 2.0～2.5MPa
Water inlet method: water inlet at both ends, water inlet on both sides
Structure: standard spare parts, easy to disassemble
Sealing: pressure tested
Organizational structure at both ends: clamp type, card type, inner spring type.
What is the advantages and disadvantages of stainless steel membrane housing ?
Stainless steel membrane housing perform the best on the quality and pressure -bearing . However , because of the materials limitations, the price is the highest among all kinds of the membrane housings
