Daily management of reverse osmosis RO water purification equipment

Daily management of reverse osmosis RO water purification equipment

We all know that the operation of reverse osmosis water purification equipment requires four steps: pre flushing, flushing, operation, and post operation flushing. So we should do

To: Each time the R0 equipment is started, the inlet valve should be slowly opened to prevent the reverse osmosis membrane from being damaged due to momentary high pressure. Attention should be paid to static back pressure during operation, and it is not allowed

The pressure on the clean water side is higher than that on the inlet and concentrated brine sides.

Daily management of R0 reverse osmosis equipment

(1) The turbidity of the effluent after clarification and filtration of the raw water should be maintained below 1 mg/L.

(2) During operation, the control SDI value should not exceed 4.

(3) The turbidity value of the precision filter effluent should be maintained below 0.2mg/1.

(4) In actual operation, the optimal pH value is 6 5-7.5.

(5) Control the recovery rate to 75% during operation

(6) The higher the operating pressure, the greater the water permeability (within the allowable range), and the operating pressure is generally controlled at 1 3~1.4 MPa range.

(7) Temperature has a significant impact on the permeability of R0. For every 1C increase in water temperature, the permeability increases by 2.7%, but the operating water temperature cannot exceed 35C.

(8) Add NaHS03 solution to the inlet of the softener and maintain the ORP value in the range of 70~130 to remove excessive residual chlorine in the water, so that the residual chlorine is less than 0 1 mg/L and kill in water

Microbiology, protection of R0 equipment, role of reverse osmosis membrane.

Whether in operation or shutdown, attention must be paid to preventing dehydration of the reverse osmosis membrane, as once the reverse osmosis membrane is dehydrated, it can cause irreparable damage. reverse osmosis.Although the operation and maintenance of the equipment are simple, we must not neglect them. We must do a good job in daily maintenance.

The above is the daily management of reverse osmosis RO water purification equipment that Hongjie Water brings to everyone. We hope it can help you!
