Daily Maintenance and Troubleshooting Methods for Soft Water Equipment

The processes of various软化 water treatment equipment are very similar, essentially including the following stages: working (water production, etc.) → backwashing → salt absorption (regeneration) → slow rinse (exchange) → rapid rinse. Depending on the specific process or control requirements, there may be additional steps. Any软化 water treatment equipment based on sodium ion exchange is developed upon these five stages (with fully automatic软化 water equipment adding the step of saltwater re-injection).

Boiler Softening Water Equipment Common Faults and Solutions

Softeners No Longer Generating

A. Check for proper electrical supply (including checking fuses, plugs, switches, etc.).

Reschedule the time.

Check or replace the controller;

D. Inspect or Replace the Motor

2. Non-Saline

A. Increase Inflow Pressure

B. Inspect piping and remove obstructions

C. Pipeline Inspection

D. Clean or replace the jet unit

E. Inspect and repair valve bodies or replace

F. Inspect Drainage Pipelines

G. Select the jet nozzles and drainage flow restrictors according to the instructions provided.

3. The water softener is delivering hard water.

A. Shut off or inspect bypass valves;

Ensure there is solid salt inside the salt box.

Replace or clean the jet nozzle.

Check the salt box water filling time.

Ensure that the center tube and O-ring are not cracked.

F. Inspect and repair valve bodies or replace them.

Properly set and adjust the regeneration time or the volume of water for the cycle.

Add resin to an appropriate amount, and identify the cause of resin loss.

I. Reduce incoming water turbidity or remove and clean or replace the flowmeter.

4. Salt box water overflow or spillage

A. Reset Salt Box Refilling Schedule

B. Inspect the jet nozzles and salt absorption pipeline for any blockages

C. Clean salt valves and piping

Close the inlet valve and then open it or install a level controller after power is restored.

E. Inspect and Maintain Level Controllers

5. Pressure loss or rust in the piping

A. Clean the softener pipeline

Wash the control valve, add resin cleaning agent to the resin bed. Increase the regeneration frequency.

C. Inspect the anti-money laundering and saltwater immersion processes, increase the regeneration frequency, and extend the anti-washing duration.

Iron removal facilities have been added to the system.

6. Resin is discharged through the drainage pipe.

A. System exhaust completed

B. Replace the Water Distributor

C. Inspect and adjust the appropriate drainage flow

7. Continuous drainage from the drain outlet

A. Inspect and repair valve bodies or replace

B. Set the valve to the operating position or close the bypass valve, then open it after the power supply is normal.

The C.F63 control valves connect the outlet pipe with the drainage pipe during backwashing.

8. Saltwater contained in the outflow pipe

A. Clean or inspect the jet nozzles

B. Inspect salt valves or clean debris

Increase the washing time

9. Decreased cycle water volume

A. Re-generate in accordance with the correct operational requirements

Increase the flow rate and duration of anti-dirtying, using resin cleaner or replacing new resin.

C. Reset the appropriate salt usage amount

Based on the laboratory results, recalculate and set anew.

E. Perform temporary manual regeneration and reset the regeneration cycle

Remove the flow meter and flush with water; if it still cannot be rotated, replace the flow meter.

Section II: Maintenance of Softening Water Equipment

1. Operations and Maintenance

Boiler软化water equipment, fully automatic soft water systems should perform the following maintenance and care during operation:

① Ensure stable input voltage and current. Prevent dampness and water immersion. Prevent the formation of salt bridges on salt valves. Prevent damage to electrical control devices. External sealing covers should be installed on the electrical control device.

② Regularly add solid granular table salt to the salt box (strictly prohibited to add fine salt or iodized salt), ensuring that the salt solution inside the box is supersaturated. When adding salt, be cautious not to sprinkle the granular salt into the salt well, which could block the salt absorption lines. Since solid granular salt contains varying amounts of impurities, a large quantity of impurities may settle at the bottom of the salt box, blocking the salt valve. Therefore, it is necessary to clean the impurities from the bottom of the salt box regularly. To clean, open the drain valve at the bottom of the salt box and flush with clean water until no impurities are discharged. The cleaning cycle of the salt box should be determined based on the impurity content of the solid granular salt.

Regularly inspect the aeration jet and salt absorption pipeline for air tightness to prevent leakage affecting the regeneration effect.

④ Annually, the water softener should be disassembled once. Clean the upper and lower distributors and the quartz sand bed, and inspect the resin for loss and exchange capacity. Replace severely aged resin; for iron-poisoned resin, use hydrochloric acid solution for revival.

2. Maintenance suspension

Before temporary shutdown, fully regenerate the resin and convert it to sodium type for wet maintenance.

During the summer shutdown (such as for softeners used in heating boiler systems, which are typically shut down for several months during the summer), the softener should be flushed at least once a month to prevent the growth of microorganisms in the exchange tank, which can cause the resin to mildew and cake. If mildewing of the resin is detected, sterilization treatment can be conducted. Generally, soak the resin in a 1% formaldehyde solution for several hours, then rinse until the formaldehyde odor is gone.

Winter shutdown requires antifreeze measures to prevent the expansion and cracking of resins due to frozen moisture inside. Resins can be stored in a saltwater solution, and the concentration of the saltwater should be adjusted according to the temperature conditions.
