Sand Filters and Disc Filters: Choosing a Pretreatment Stage

A media bed and a disc stack retain debris through different structures. Their suitability depends on particle loading, water chemistry and the cleaning facilities at the site.

How it applies to the water system

Sand or multimedia systems need vessel space and an adequate backwash supply. Disc banks offer modular configurations but still require a suitable grade, pressure and drainage arrangement.

Selection and operating considerations

They can also be combined in a treatment train. Review the raw-water analysis and downstream requirements before treating them as interchangeable alternatives.

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
