AFM Sediment & Turbidity Reduction Filter – 12×52 FRP Vessel – Automatic Backwash

The 12×52 sediment and turbidity reduction filter captures suspended particles to improve water clarity. AFM is activated glass filter media used as a physical filtration stage, with routine backwashing to remove accumulated material from the bed.

This complete media-vessel package includes the 12×52 FRP vessel, Runxin automatic backwash valve and AFM activated glass filter media.

Key Features & Benefits

• Clearer water: Reduces suspended sediment and particulate matter responsible for turbidity.
• Activated glass media: Provides a filtration bed designed to resist biofouling when correctly operated.
• Useful pre-filtration: Helps reduce particulate loading on downstream cartridges and other treatment equipment.
• Automatic backwash: A programmed cleaning cycle reduces hands-on valve operation. The inlet supply and waste drain must still provide the required backwash capacity.
• FRP construction: A corrosion-resistant vessel body houses the treatment bed.

Applications

• Sediment filtration for borehole, wellpoint, rainwater and municipal supplies, following a water-quality assessment.
• Point-of-entry filtration and suitable commercial water processes.
• Pre-filtration before fine cartridges, UV or reverse osmosis where required by the treatment design.

Technical Specifications

• Product code: H2OW1223
• Vessel size designation: 12×52; nominal vessel designation, not the installed height including the valve.
• Vessel material: Fibreglass-reinforced plastic (FRP).
• Treatment media: AFM activated glass filter media
• Head / control: Runxin automatic backwash valve
• System design flow: Select from the water analysis, media bed depth, required outlet quality and available backwash supply. Vessel size or valve capacity alone does not establish the treatment flow.

What’s Included

• Vessel: 1 × 12×52 FRP vessel.
• Control valve: 1 × Runxin automatic backwash valve.
• Media: AFM activated glass filter media supplied for this product configuration.

Installation & Use

• Before installation: Have the source water tested and confirm the treatment sequence, operating flow and backwash requirements.
• Site connections: Arrange inlet and outlet pipework, suitable isolation/bypass provision and a correctly sized drain for backwash water.
• Commissioning: Load and condition the media according to the media and valve instructions. Leave the required expansion space; supplied bag quantities are not an instruction to fill the vessel to the top.
• Cleaning control: Programme the valve for the site’s water quality and follow the fitted valve instructions.
• Operating limits: Use the lowest pressure and temperature limits of the vessel, valve and other fitted components. Isolate and depressurise before opening the vessel.

Important Information

• Treatment role: AFM captures particles. Dissolved iron or manganese generally requires an oxidation stage before the resulting solids can be filtered.
• Filtration performance: Particle capture depends on the AFM grade, media layering, filtration velocity and feed water. The vessel is not assigned an absolute micron rating here.
• Water hygiene: Resistance to biofouling in the media does not mean the water is disinfected. Provide a separately designed disinfection stage where required.
• Bed care: Use the specified media grading, support arrangement and expansion space; backwash at a flow that cleans the bed without washing media out.
• Complete treatment design: Additional oxidation, pH correction, softening or disinfection may be required for the intended use. A media vessel alone does not establish that water is suitable for drinking.
