Troubleshooting and Daily maintenance of Water softener

With the acceleration of the process of industrialization, the problem of water pollution has become more and more serious while productivity has increased. Water softener and water purification plant are very common way to solve the problem of water pollution. The maintenance and troubleshooting methods are very important.

Daily maintenance of Water softener

1) Ensure that the input voltage and current are stable, prevent moisture and flooding; prevent the formation of salt bridges on the salt valve and prevent the damage of electric control device.

2) Put solid industrial salt into the salt tank regularly (adding refined salt or iodized salt is strictly prohibited). Make sure that the salt solution in the salt tank is supersaturated. When adding salt, be careful not to sprinkle solid industrial salt into the salt well and block the salt suction line.

3) Since solid industrial salt contains a certain amount of impurities, a large amount of impurities will be deposited at the bottom of the salt tank and block the salt valve, so the impurities at the bottom of the salt tank shall be cleaned regularly.

4) When cleaning, can open the drain valve at the bottom of the salt tank and rinse with clean water until no impurities flow out. The cleaning cycle of the salt tank should be determined according to the impurity content of solid industrial salt.

5) Regularly check the air tightness of the ejector and the salt suction pipeline to prevent air leakage and affect the regeneration effect.

6) Disassemble the water softener once a year. Clean up the impurities in the upper and lower water distributors and the quartz sand cushion, check the loss and exchange capacity of the resin, replace the severely aging resin.

7) The resin should be fully regenerated once before stop running the water softener. Convert the resin to sodium form for wet maintenance. When the water softener is not used in summer (such as the water softener used in heating boilers, generally for several months in summer), the water softener should be flushed at least once a month to prevent the growth of microorganisms in the exchange tank, which may cause the resin to mold and agglomerate. If the resin is found to be moldy, it can be sterilized. Anti-freezing measures should be taken to prevent the resin from swelling and breaking due to freezing in winter. The resin can be stored in an aqueous salt solution.

Troubleshooting of Water softener

1) Water softener does not regenerate

Solution: Check whether the power supply is normal, including the fuse, plug, switch, etc.; reset the time; check or replace the controller; check or replace the motor.

2) The product water hardness can not meet the demand

Solution: Close or repair the bypass valve; Ensure that there is solid industrial salt in the salt tank; Replace or clean the jet; Check the water filling time of the salt tank; Ensure that the center tube and O-ring are not broken; Check and repair the valve body or replace; Correctly set and adjust the regeneration time or periodic water production; Add resin to an appropriate amount, and find out the cause of resin loss; Reduce the turbidity of the influent water or remove the flow meter for cleaning or replace the flow meter.

3) No salt suction

Solution: Increase the inlet water pressure; Check the pipeline to remove blockages; Clean or replace the jet; Check and repair the valve body or replace; Check the drain pipeline

4) Excess or overflow of salt tank water

Solution: Reset the replenishing time of the salt tank; Check whether the jet and salt pipes are blocked; Clean the salt valve and pipes

5) The resin is discharged through the drain pipe

Solution: Exhaust the system; Replace the water strainer; Check and adjust the proper drainage flow.

6) Reduced product water capacity

Solution: Regenerate the resin according to the correct operation requirements; Properly increase the backwash flow time; Reset the appropriate amount of salt; Temporarily manual regeneration, and reset the regeneration period; Remove the flow meter and rinse with water, if it still cannot be turned, replace the flow meter.
