Katalox Light Iron & Manganese Removal Filter – 18×65 FRP Vessel – Automatic Backwash

The 18×65 iron and manganese removal filter uses a manganese-dioxide-coated medium to support the oxidation and filtration of iron and manganese. It can also form part of a treatment system for hydrogen sulphide, subject to water analysis and the required oxidation process.

This complete media-vessel package includes the 18×65 FRP vessel, Runxin automatic backwash valve and Katalox Light catalytic filtration media.

Key Features & Benefits

• Targeted treatment: Helps reduce iron and manganese associated with staining and deposits in water systems.
• Catalytic filtration: Supports the conversion and capture of dissolved contaminants when the water chemistry and oxidant conditions are suitable.
• Downstream protection: Can reduce metal loading ahead of further filtration, softening or reverse osmosis.
• 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

• Borehole and wellpoint water with confirmed iron or manganese contamination.
• Point-of-entry treatment and selected commercial processes, sized to the tested water quality.
• Pre-treatment ahead of downstream equipment where iron or manganese reduction is required.

Technical Specifications

• Product code: H2OW1203
• Vessel size designation: 18×65; nominal vessel designation, not the installed height including the valve.
• Vessel material: Fibreglass-reinforced plastic (FRP).
• Treatment media: Katalox Light catalytic filtration media
• Head / control: Runxin automatic backwash valve
• Media inlet pH range: 5.8–10.5 is the manufacturer’s media range; the required treatment pH depends on the contaminants present.
• 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 × 18×65 FRP vessel.
• Control valve: 1 × Runxin automatic backwash valve.
• Media: 5 × 30 kg bags of Katalox Light media (150 kg supplied).
• Internals: Riser pipe and distribution components as specified for this vessel.

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

• Water chemistry: Confirm pH, iron, manganese, dissolved oxygen and any hydrogen sulphide before selection. Manganese treatment can need higher pH and more contact time than iron treatment.
• Oxidation: Aeration or a controlled oxidant stage may be required. Backwashing alone does not replace the necessary oxidation conditions.
• Media maintenance: Backwash and rinse to clear retained solids; monitor treated-water quality and pressure loss.
• 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.
