A multimedia sand filter is similar in operation to a conventional sand filter, but instead of using a single layer of filter sand, CWC multimedia filters use 3 layers of proprietary filter media. The Deep Bed Multimedia principle offers a higher degree of filtration, longer filtration cycles and lower backwash water consumption than obtained from conventional sand filters or dual media filters. By operating the filters at higher than normal operating pressures, we are able to promote extremely fine particle size removal; typically 5-microns and better. The differing media layer depths and particle sizes also allow for far higher solids holding capacity without turbidity leakage. The solids retention abilities of multimedia sand filters allow them to be operated at high filtration velocities, which result in reduced installation space and capital costs.
