FRP Pressure (Sand) Filters

An FRP pressure sand filter is a very efficient filter unit employed on the removal of suspended solids, sediment, and particulate matter from water or fluid. FRP is an abbreviation for Fiberglass Reinforced Plastic, a light weight, strong, and corrosion-resistant material. All these features make it optimum for high-pressure and severe conditions. 

Key Components

• FRP Tank: The filter matrix comprises fiberglass reinforced plastic, increased strength, and long-term durability even under unfavorable conditions.
• Media Bed: A specially layered filter media bed, usually silica sand, retains and filters out impurities as water passes through within the tank.
• Underdrain System: It is located at the tank bottom and captures the filtered clear water and also effects uniform distribution upon backwashing.
• Control Valve: It controls the incoming water entering into the system and outgoing from the system and backwash cycle for maintenance.

FRP pressure sand filters find wide application due to high reliability, economic viability, and corrosion resistance. They can be installed in freshwater to seawater conditions.

Most Popular FRP Pressure Sand Filter Models

• Top mounted FRP pressure sand filters
• Side mounted FRP pressure sand filters
• Automatic FRP pressure sand filters
• Multi-layer or multimedia FRP pressure sand filters
• Dual stage FRP pressure sand filters
• High flow FRP pressure sand filters
• Skid-mounted FRP pressure sand filters
  

Filters are easy to install and offer long operation lifetimes and are one of the most widely used for the majority of water treatment plants.
