Cleaning frequency should follow operating condition and the equipment instructions. Debris loading and flow changes can make a fixed weekly schedule unsuitable.

How it applies to the water system

Backwash duration depends on the specified flow, discharge condition and control sequence. Extend or shorten a cycle only after establishing what the manufacturer requires.

Selection and operating considerations

Record the pressure recovery and discharge condition after cleaning. Persistent poor recovery may indicate deposits, distributor problems or an incorrect cleaning flow.

Planning the requirement in Sabah

For a hotel, resort pool or commercial filtration plant in Sabah, plan the work around site access and the operating schedule. Provide vessel dimensions, existing media records and pump information before arranging media supply or service. Record the water condition that prompted the enquiry.
