BIRM Iron & Manganese Removal Filter – 13×54 FRP Vessel – Automatic Backwash

The 13×54 iron and manganese removal filter uses dissolved oxygen in the feed water to support iron oxidation, after which the resulting particles are retained in the filter bed. Manganese reduction is possible when the water meets BIRM’s more demanding pH and chemistry requirements.

This complete media-vessel package includes the 13×54 FRP vessel, Runxin automatic backwash valve and BIRM catalytic filtration media.

Key Features & Benefits

• Iron treatment: Helps reduce iron-related staining and deposits in suitable borehole or wellpoint water.
• No salt regeneration: The media is cleaned by backwashing rather than regenerated with softener salt.
• Conditional manganese reduction: Can treat manganese where pH, oxygen and the remaining water chemistry are suitable.
• 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 meeting BIRM’s feed-water requirements.
• Point-of-entry systems addressing iron-related staining.
• Pre-treatment for downstream equipment where a water analysis confirms suitability.

Technical Specifications

• Product code: H2OW11
• Vessel size designation: 13×54; nominal vessel designation, not the installed height including the valve.
• Vessel material: Fibreglass-reinforced plastic (FRP).
• Treatment media: BIRM catalytic filtration media
• Head / control: Runxin automatic backwash valve
• Media pH requirements: Iron: at least 6.8. Manganese: typically 8.0–9.0, with pH below 8.5 where iron is also 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 × 13×54 FRP vessel.
• Control valve: 1 × Runxin automatic backwash valve.
• Media: BIRM catalytic filtration 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

• Iron removal conditions: The manufacturer specifies pH of at least 6.8 and dissolved oxygen of at least 15% of the iron concentration, using the same concentration units.
• Manganese removal conditions: The manufacturer recommends pH 8.0–9.0; when iron is also present, pH should remain below 8.5.
• Feed-water compatibility: BIRM is unsuitable for untreated water containing oil or hydrogen sulphide. Organic loading and any proposed oxidant addition must also be checked against the media requirements.
• Pre-treatment: Aeration or pH correction may be required before the BIRM vessel. Do not assume the media can treat every borehole supply without additional equipment.
• 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.
