The 500 LPH FRP Multigrade Water Filtration System with Automatic Multiport Valve is a compact, high-performance filtration solution designed to improve water quality for residential and commercial applications.
The system uses a durable FRP pressure vessel filled with multiple layers of filtration media, such as anthracite, graded sand, and support gravel. As raw water passes through these layers, the system helps remove suspended solids, sand, silt, dirt, and turbidity, producing clearer water for further treatment or general utility use.
Its automatic multiport valve controls filtration and cleaning cycles, including service, backwash, and rinse, reducing the need for frequent manual operation. During backwashing, the water flow is reversed to flush accumulated contaminants from the filter media and discharge them through the drain.
With a nominal treatment capacity of 500 litres per hour (LPH), this single-cylinder system is suitable for homes, villas, apartments, hotels, offices, institutions, and small commercial facilities.
Key benefits: automatic operation, compact single-vessel design, corrosion-resistant FRP construction, multigrade filtration, easy maintenance, and improved clarity of incoming water.
Note: A multigrade filter primarily handles suspended particulate matter and turbidity. Removal of dissolved salts, hardness, iron, microorganisms, or other specific contaminants may require additional treatment stages depending on the source-water analysis.
