SNP Aqua filter is known for its high quality and dependability.

Our products were at the origins of the industry-standard plastic filter housing and are the foundation for the filtration products that we offer today.

Membrane housing is a pressure vessel for loading membrane elements in a reverse osmosis water treatment system. Currently, there are three types of membrane housings with different materials for water treatment on the market: FRP (fiberglass reinforce plastic), stainless steel and PVC. However, in recent years, more and more reverse osmosis water treatment systems have chosen to use FRP membrane housing. This is because the FRP membrane housing has a strong advantage in terms of pressure bearing capacity, design size, material properties and operating temperature compared to stainless steel and PVC membrane shells.

As is well-known, reverse osmosis system relies on pressure to achieve the purpose of purification or concentration. While the membrane housing is the vessel that bears this kind of pressure. In a reverse osmosis system, the higher the concentration of raw water, the greater the pressure that needs to be applied. Obviously the FRP membrane housing has higher pressure capacity than stainless steel membrane housing and PVC membrane housing. It means that FRP membrane housing can be used in more types of water treatment systems.
