The decrease in average temperature in winter can endanger the normal operation of sewage treatment equipment. In order to better ensure the normal operation of the equipment in winter, everyone must take protective measures. Below, the editor will share with you several maintenance methods for sewage treatment equipment.

Sharing of maintenance techniques for winter water treatment equipment

A. The tank and membrane equipment shall carry out sewage treatment and discharge on time as required to prevent turbid water from freezing and damaging the equipment and gate valves.

B. The equipment and vessels that have stopped operating should be drained of clean bottom water. Before putting the equipment into use, backwashing and backwashing should be carried out. Local areas with pressure relief should prevent pressure buildup. It is necessary to ensure that the equipment is listed, registered, and inspected for anti freezing and water discharge.

C. The personnel responsible for the supervision and inquiry of regional fire safety, explosion-proof, and antifreeze insulation shall be appointed by the regional person in charge. They shall carry out inquiry and recognition of antifreeze equipment. After the work is carried out, the actual operating personnel shall check and acknowledge to ensure that the records are traceable and accessible.

D. Pipeline antifreeze: Pipelines exposed to the outside must be insulated and insulated with insulation materials. During the severe freezing period, anti freezing measures should be taken to maintain the fluidity of calcium and magnesium ions in the water supply pipe as much as possible, in addition to the above measures, to prevent the pipeline from freezing and losing water.

E. Gate valve antifreeze: It is necessary to use some insulation materials to bundle and carry out thermal insulation.

After the self suction sewage pump is stopped from use, the remaining water in the centrifugal water pump and pipeline should be drained, and the external soil should be cleaned up to prevent the frozen water from freezing and causing the pump casing and water pipe to expand and crack.

Ultrafiltration membrane and integrated equipment

Using traditional heating methods and adopting a charcoal furnace heating strategy in the equipment room, the charcoal furnace is placed in the equipment room and the staff take care of the room equipment, fire and add charcoal.

The method of using insulation boards for heating insulation is adopted to ensure that the temperature at each point in the equipment room is not less than 5C.

RO reverse osmosis system

If the average temperature is too low in winter, it can cause the pipeline to freeze and break due to icing. Generally, customers are suggested to use heating to the equipment if necessary. If the source water temperature is very low, it is also necessary to carry out source water heating to raise the temperature of the house. For example, using a furnace or radiator, and electric heating devices can also be used. If the RO reverse osmosis equipment is not running in winter, it is necessary to release the water in the equipment and take the RO reverse osmosis membrane into the room (with maintenance solution) to avoid harm to the RO reverse osmosis membrane due to icing.

When installing RO reverse osmosis equipment in a room, it is necessary to ensure that the indoor temperature is not less than 0 degrees Celsius, because the volume of water will swell during the entire condensation process. If it freezes, it will immediately cause all pipelines, filter bottles, membrane shells, etc. of the water purifier to crack, resulting in water seepage.
