An FRP (Fiberglass Reinforced Plastic) vessel is a strong, lightweight, and corrosion-resistant tank used in water treatment systems to hold and process water under pressure. Made by reinforcing plastic with fiberglass, these vessels offer excellent durability, chemical resistance, and long service life.

In RO water plants, FRP vessels are commonly used to house filter media such as sand, carbon, or softening resin. They are preferred for their high strength-to-weight ratio, low maintenance, and resistance to rust and chemical corrosion, making them ideal for domestic ,commercial and Industrial applications.
