Technical Datasheet for Fiberglass Reinforced Plastic (FRP) Vessels in Water Treatment Plant
FRP Multimedia Vessels
Product Description
FRP Multimedia Vessels are premium-grade fiberglass reinforced plastic (FRP) pressure vessels engineered for water treatment applications such as multimedia filtration, activated carbon filtration, water softening, and reverse osmosis pre-treatment systems. Manufactured with food-grade HDPE liners and reinforced composite fiberglass shells, the vessels provide high strength, corrosion resistance, lightweight handling, and long operational life.
