The membrane gets clogged, and there are many possible causes for this – scale, iron, microorganisms, organic substances, as well as suspended particles and colloids in the raw water can all lead to such issues. To determine the specific cause, it is necessary to examine the performance of the pre-treatment process, the changes in pressure and flow rate of the RO unit over time, and even analyze the deposits on the surface of the RO unit. Cleaning is required to restore RO to normal operation

Different pollutants require different cleaning solutions

1. If the membrane is clogged, check whether the pretreatment was not done properly or if scaling is the cause. 2. You have too few membranes, so only that much water can be produced; it’s not realistic to try to increase the production by applying pressure.

Prolonged lack of cleaning or inadequate pre-treatment can cause membrane blockage; it is recommended to seek a professional company to clean the membrane.

Is there a blockage inside the membrane filament? Is the discharge of concentrated water still too large?

It’s very likely that the membrane is contaminated; it should be cleaned

How long has your reverse osmosis system been in use? Have you used any reverse osmosis scale inhibitors? In this case, it’s likely that the membrane is clogged and needs to be cleaned

Based on the principles of reverse osmosis, the operating pressure and water production volume are related to the salt content of the RO feedwater; the higher the salt content, the higher the operating pressure will be under the same recovery rate. Additionally, temperature is also an important factor affecting pressure and water production volume. Other factors such as pH also have an impact. Also, it is necessary to check whether the pretreatment has been done properly and whether the feed water meets the requirements for RO feed water. Also, check whether the membrane is damaged.
