Choosing Media for Sand and Multimedia Filters

Select filter media by its function, grading and compatibility with the vessel loading schedule. Silica sand, anthracite and garnet are not interchangeable simply because they are granular materials.

How it applies to the water system

A layered bed needs appropriate density and particle-size relationships. Its backwash requirement must be achievable with the installed pump and drainage.

Selection and operating considerations

Activated carbon serves adsorption duties that differ from ordinary sand filtration. Define the contaminant and intended treatment outcome before choosing a replacement medium.

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.
