What are the causes of reverse osmosis membrane fouling in purified water equipment- Pure Water Equipment - Jiajie - Jiajie Pure Water Equipment Manufacturer


As a common water purification equipment, pure water equipment is being applied more and more widely, especially in today's society where people's awareness of drinking water safety is gradually strengthening. Whether it is installing pure water equipment in residential areas or in water plants, the number of pure water equipment is continuously increasing.

As for scale, everyone is familiar with it, especially our household kettle, which will experience scale after being used for a period of time, which is related to the composition of the water.

1. During the operation of the equipment, the pressure generated during low-pressure cleaning will produce a portion of water, and the concentration of water on both sides will increase accordingly, which will also cause an increase in salt content. Salt contains a large amount of precipitable substances, and over time, scaling will occur.

2. In terms of design, in order to better replace the reverse osmosis concentrate, it is necessary to ensure that the salinity in the concentrate is as low as possible. In addition, insufficient mixing of drugs during dosing is also one of the key reasons for fouling of the reverse osmosis membrane.

3. The leakage of scale inhibitor dosing equipment is quite serious, which may affect the insufficient dosage of scale inhibitor and result in poor solution effect. During the operation process, insufficient attention was paid to whether the operating procedures and other regulations were in compliance, and the equipment was not cleaned in a timely manner after shutdown.
