    1. Overview of Stainless Steel Membrane Housing:
    Stainless Steel Membrane Housing, also known as pressure vessels, is mainly used to fill the reverse osmosis membrane. Its quality directly affects the performance of the reverse osmosis membrane, causing reverse osmosis string membrane sloshing to damage the reverse osmosis membrane, and the leakage of the membrane end leads to contamination of the finished product. The high pressure of the system leads to the gradual shape of the membrane shell and the gradual leakage of the weld seam, causing unnecessary trouble and waste to the user.

    2. Classification of Stainless Steel Membrane Housing:

    (1) The reverse osmosis membrane shell is divided into glass fiber reinforced plastic membrane shell and stainless steel 304 or 316 membrane shell in terms of material;
    (2) In terms of usage, it can be divided into household membrane housing and industrial large membrane housing;
    (3) Functionally divided into ultra-low pressure membrane shell and low-pressure membrane shell;
    (4) According to the size, it can be divided into 4-inch 1-core, 2-core (4021, 4040, 4080), 8-inch 1-core, 2-core, 3-core, 4-core, 5-core (8040, 8080, 80120) , 80160, 80200) etc.;
    (5) The water inlet method is generally divided into an end in and end out, ordinary side in and side out, etc.

    3. Selection of Stainless Steel Membrane Housing:

    (1) The size of the membrane shell used in the reverse osmosis system is mainly determined by the designer's requirements. The arrangement and segment requirements of the membrane are different. According to the different import and export angles, they are divided into three types: 0 degrees, 90 degrees, and 180 degrees. In theory, the side water inlet is better, but it increases the probability of water leakage from the pressure vessel.
    (2) The water flow and pressure of the 8-inch membrane is much larger than that of the 4-inch RO membrane. If two ports are opened on the membrane shell port, the pressure resistance of the end face will be reduced, and the installation will also increase a lot of trouble, so The 8-inch membrane shell has water inlet and outlet on both sides;
    (3) The main problem is the flow rate of concentrated water. Because the maximum water recovery rate of a single membrane element is designed to be 16%, in order to improve the utilization of water, it is completed by using multiple membranes in series. The pressure drop is much larger than that of an 8-inch membrane, so the number of series connections cannot be too many. The specific number of series connections depends on the water quality and design parameters. Secondly, the choice of high-pressure pumps should be considered.

    4. Features of Stainless Steel Membrane Housing:

    (1) All are made of stainless steel 304 or 316, and the inside and outside of the membrane shell are polished;
    (2) Water inlet method: water inlet at both ends and water inlet taps on both sides;
    (3) Structure: standard spare parts, convenient and quick to disassemble;
    (4) Tightness: After the pressure test, the pressure resistance is high, and it is not easy to age;
    (5) Organization structure at both ends: clamp type, flange type, built-in type, 4040 membrane shell head uses ABS end caps.
