GAC Media FRP Vessel 13x54 – Automatic Backwash Complete with Media

The GAC Media FRP Vessel 13x54 with automatic backwash is a higher-capacity water-filtration system designed to reduce chlorine, odours, organic compounds and selected volatile organic compounds (VOCs). It includes a durable 13x54 FRP vessel, a RUNXIN automatic backwash head and granular activated carbon (GAC) media for larger residential, commercial and selected process-water applications.

GAC media helps improve water taste and odour, while automatic backwashing cleans and loosens the media bed to support consistent operation and reduce manual maintenance.

Key Features

• GAC filtration: Helps reduce chlorine, odours, organic contaminants and selected VOCs.
• Automatic backwash: RUNXIN valve provides scheduled media cleaning.
• Durable FRP vessel: Corrosion-resistant and suitable for pressurised water systems.
• Higher-capacity treatment: Suitable for larger homes, hospitality and commercial point-of-entry systems.
• Operating pH range: Approximately 5.5–9.5, subject to the selected carbon and feed-water chemistry.

• Empty vessel weight: Approximately 8.5 kg

GAC Filter Residence Time and Flow Rate

The chart below compares estimated media residence time across common FRP vessel sizes at different flow rates. For effective granular activated carbon treatment, a contact time of approximately 3 minutes or longer is generally preferred, subject to feed-water quality, carbon specification, treatment objective and the contaminants being addressed.

Operating Considerations

• Provide sufficient backwash flow to expand and clean the media bed.
• Allow adequate freeboard for media expansion during backwashing.
• Actual treatment performance depends on contaminant concentration, competing organics, temperature, pH and contact time.
• Carbon replacement frequency must be based on water quality, throughput and breakthrough monitoring rather than time alone.

Applications

• Large residential point-of-entry municipal-water filtration
• Hotels, restaurants, offices and commercial premises
• Chlorine reduction ahead of reverse osmosis
• Taste and odour improvement
• Food, beverage and selected process-water applications, subject to design confirmation
