How Automatic Disc Filtration Works

During filtration, compressed grooved discs form a path that retains suspended material. In a compatible automatic design, reverse cleaning flow releases and washes debris from the stack.

How it applies to the water system

The controller may respond to a timer, differential pressure or another configured signal. Model-specific pressure and cleaning-flow requirements must be available at the bank.

Selection and operating considerations

Sequential cleaning can help maintain supply through the remaining units, provided the bank is designed for that duty. Confirm the operating sequence and service flow before commissioning.

Planning the requirement in Sabah

For irrigation intakes, hotel landscape systems or industrial pretreatment in Sabah, the source and downstream equipment define the filtration duty. Include normal and peak flow, the existing pump arrangement and access to a cleaning-water supply in the project brief.

Information to prepare

What should I send SWFI for this requirement in Sabah?

Send the site location, source-water information, operating flow and pressure, and the equipment model or photographs where available. SWFI is based in Kota Kinabalu and can review the requested supply or service scope against the site duty.

Discuss your water-system requirement with SWFI

Sabah Water Filter Industries (SWFI) is based in Kota Kinabalu, Sabah. Share your site details for equipment selection, sourcing or maintenance enquiries. The proposed model and scope depend on the actual water conditions and installation requirements.
