The whole bed, matched and shipped together
Multimedia Filter Packages
Complete pre-matched media packages — anthracite, silica sand, garnet and the full support gravel set — sized to your vessel diameter and bed depth so nothing has to be reconciled on site.

Overview
Ordering media layer by layer from different suppliers is where multimedia beds go wrong: densities and gradations that were never designed to work together intermix on the first backwash and never re-stratify. A matched package removes that risk.
Give us the vessel diameter, the design filtration rate and the target effluent quality. We return a bed schedule — layer, gradation, depth, volume and weight — plus a single quotation covering all of it.
Packing options
- Per-layer bags, labelled by layer25 kg / 1,000 kg
Loaded in installation order so the bed is built bottom-up without re-sorting
