How often does RO membrane purified water equipment need to be drained and cleaned? 

How often should the RO membrane purified water coagulation sedimentation equipment be cleaned? RO membrane purified water equipment is mainly used for the separation of impurities in water. Through reverse osmosis membrane technology, impurities and bacteria in water are separated, so as to achieve the purpose of purifying water quality. When the RO membrane purified water equipment has been used for a long time, it is necessary to conduct sewage cleaning to ensure the high efficiency of the equipment.

1. Generally speaking, the RO membrane purified water coagulation and sedimentation equipment will be overhauled once in the second half of the year for the red rust condition, and it will be determined whether the sewage is cleaned according to the condition.

2. When everything is normal, the equipment will automatically stop working when the pure water in the pressure tank is full and the sewage will be discharged.

3. Check the operation of the inlet and outlet sluice valves, sludge discharge valves and mechanical equipment of the sludge thickener every day and carry out maintenance, which needs to be filled with lubricating grease. The mechanical equipment and electrical equipment shall be inspected and maintained once a month, and the inclined tube sedimentation tank shall be cleaned once as much as possible.

4. If the RO membrane purified water coagulation sedimentation equipment is used to treat drinking water, the RO reverse osmosis membrane inside the equipment is generally cleaned once from June to November. The service life of RO reverse osmosis membrane components under normal use is generally 3-5 years. If the staff maintain it well during this period, it may also be used for 6 years, but if the time is too long, the RO reverse osmosis membrane needs to be replaced in time.

The mechanical equipment and gate valve of sludge thickener in RO membrane purified water equipment need to be dismantled and repaired or replaced once a year, and the fixed support, pool, side wall, etc. of inclined tube sedimentation tank need to be inspected. If necessary, maintenance and painting are also required.

6. According to the application of the equipment, the blowdown cleaning cycle of RO membrane purified water equipment in general specifications should be once every two months.

The above is the sewage cleaning cycle of RO membrane purified water coagulation sedimentation equipment. Each equipment may have different use time due to different water quality in each region, so the above data can be used as a reference, but the specific time is still based on the actual situation.
