Factors affecting the purchase of membrane in ro plant

Author:Huamo Water treatment materials FROM:Water filter membrane manufacturer TIME:2021-09-28

When designing ro membrane filter, how to choose the specifications and models of membrane in ro plant is particularly important for the daily and reasonable operation of the system, otherwise the operation quality cannot be guaranteed.

membrane in ro plant

1. Choose a membrane in ro plant according to the inlet water body

Ultra-low frequency membrane elements can be used for influent TDS≤1000ppm.
Anti-pollution membrane element can be used for influent water 3000ppm≥TDS≥1000ppm
Brackish water desalination membrane elements can be used for influent TDS≥3000ppm.

Seawater desalination membrane elements can be used for influent TDS≥5000ppm

2. Choose membrane in ro plant according to water production

Steel gravity water filter with a water production of 4T/H mostly uses 4040 membrane elements; for a 0.25 ton/hour machine, choose 1 4040 membrane, 2 membranes 0.5 ton/hour, and 4 membranes 1 ton/hour.
Steel gravity water filter with water production ≥ 4T/H mostly uses 8040 membrane elements, 8040 membrane elements are about 1 ton/hour, and 4 tons/hour reverse osmosis equipment choose 4 8040 membrane elements.
The reduction of desalination rate and water production is the most common fault in ro membrane filter, and the blockage of the water inlet channel of the membrane in ro plant is another typical typical common fault, as the pressure difference of the components increases. If the desalination rate and water production decrease slowly, it indicates that there are all normal blockages in the system, which can be resolved according to proper and timely cleaning. Rapid or sudden function degradation indicates that the system software is defective or operating errors, so it is necessary to take effective corrective measures as soon as possible. As other delay solutions may lack opportunities to repair the system, TDS with low water production, high water production, and high salt content may also occur.

The above are the reference factors for the selection of the specifications and models of the membrane in ro plant. The quality of the influent water and the required water production are particularly critical. Customers can compare the above methods for reference and purchase.
