1Cleaning methods for reverse osmosis equipment

Reverse osmosis equipment is currently a popular device in the water treatment industry. Generally, large-scale water treatment equipment is applied to reverse osmosis equipment. Reverse osmosis equipment can effectively remove impurities in water and microorganisms that are invisible to the human body. It has been applied in many industries. Reverse osmosis equipment

After running for a certain period of time, the equipment needs to be cleaned, so the cleaning of the equipment is also a very important issue.   

2,Low-pressure flushing of reverse osmosis equipment 

Regularly perform high flow, low pressure and low pressure on the reverse osmosis equipmentpHThe flushing of the value is conducive to removing the dirt adhering to the membrane surface, maintaining the membrane performance, or when the reverse osmosis equipment feeds waterSDISuddenly increase over5.5At the above times, low-pressure flushing should be carried out and waitSDITurn on the machine only after the value adjustment is qualified.

3Chemical cleaning of reverse osmosis membranes 

Under normal operating conditions, reverse osmosis membranes may also be contaminated by inorganic scale, colloids, microorganisms, metal oxides, etc. The deposition of these substances on the membrane surface can cause a decrease in the output or desalination rate of the reverse osmosis device in the water purification equipment, an increase in pressure difference, and even cause irreparable damage to the membrane. Therefore, in order to restore good water permeability and desalination performance, chemical cleaning of the membrane is required.

 The cleaning of reverse osmosis equipment is generally not good3～12It is sufficient to clean it once a month. If the quality of the raw water is poor, pre-treatment is necessary and the operating parameters should be adjusted to prevent damage to the reverse osmosis membrane.
