Shallow Sand Filters
FRP pressure vessels for turbidity, sediment and organic pretreatment
Overview
JIE NENG supplies multi-media and sand filtration vessels fabricated from fiberglass-reinforced plastic, sized for outdoor or indoor installation and connected in banks to match required flow rates for industrial and municipal pretreatment.
Each vessel is fitted with top and side inspection/access flanges, distribution piping and a media bed of graded sand, anthracite or multi-media layers selected for the target turbidity and particle-size reduction.
These vessels are typically the first hydraulic stage in a treatment train, protecting downstream ultrafiltration, softening or reverse osmosis equipment from fouling by coarse suspended solids.
