Vessel filter BIRM Fleck vessel 18X65, ref. FL-2910-MEC-BIRM-120

Overview

Vessel filter filled with BIRM catalytic medium, on a Fleck valve (ref. FL-2910-MEC-BIRM-120). Vessel 18X65. This filtration station provides iron and manganese removal, at point of entry to protect the whole installation. Delivered ready to install (filled vessel + valve + distribution), it treats mains, well or borehole water.

Filtration principle

BIRM is an iron/manganese-removal catalytic medium: it accelerates the oxidation of dissolved iron and manganese using the oxygen present in the water. The insoluble oxides formed are retained in the bed and flushed out during backwash, without chemical reagent, as long as the water is sufficiently oxygenated and the pH suitable.

BIRM media

The vessel is filled with BIRM catalytic medium on a gravel/silex support bed that distributes the water and retains fines. Media volume: 113.2 L. Depending on the medium, the bed is backwashed (carbon/Ecomix) or topped up as it is consumed (calcite/Corosex/Everzit), to maintain performance over time.

Valve & operation

The Fleck valve automatically drives the cycles: service (filtration), backwash, rinse and return to service (and salt regeneration for Ecomix). Triggering is timed or metered per model; a built-in bypass isolates the filter without cutting the water.

Sizing & installation

Choose the size (vessel 18X65) according to peak flow and water quality. Provide a drain for backwash and a power supply for the valve. Install frost-free, on a flat floor; an upstream sediment pre-filter is recommended to protect the medium.

Savings & ecology

Treating water at point of entry protects the whole installation: less corrosion (pH correction), more pleasant water (carbon) and preserved equipment, so fewer replacements and less maintenance. Backwash uses only water (and salt for Ecomix), without polluting additives: an effective, resource-respecting treatment.

Choosing right

To choose well, have your water analysed (pH, alkalinity, chlorine, iron) and estimate peak flow. The medium is chosen by need: carbon (taste/chlorine), calcite/Corosex/Everzit (pH correction), Ecomix (multi-parameter). The DIMM team helps you size vessel, valve and pre-treatment.

Key specifications

DIMM service & support

DIMM designs, assembles and ships turnkey vessel filters (Aquacarb/Carbsorb carbon, Calcite/Corosex/Everzit pH correction, Ecomix multi-layer) on Clack valves, plus the hoses and accessories. Our teams analyse your water, size vessel and valve and advise the right medium and pre-treatment. Every item is identified by its article code, with manufacturer's warranty, parts and refill media available. From advice to commissioning, we support installers and homeowners, from sizing the vessel and valve to the choice of medium and maintenance follow-up, with a stock of refill media and parts immediately available.

Good to know

The medium is chosen from the water analysis: carbon for taste and chlorine, calcite/Corosex to raise an aggressive pH, Ecomix for multi-problem well water. Provide the backwash (sufficient flow and drain) and, for pH-correction media, periodic checking and topping-up of the level as they are consumed. An upstream sediment pre-filter protects the medium and spaces out backwashes, while a regular water analysis lets you fine-tune the valve setting.

Applications

These vessel filters are installed at point of entry (whole-house or building protection), in residential as well as tertiary and agricultural settings. Depending on the medium, they polish taste, correct pH or treat several parameters. They combine with a sediment pre-filter and, if needed, aeration, for healthy water and protected plumbing year-round.

Warranty & re-supply

Station assembled and distributed by DIMM, identified by its Business Central article code for reliable ordering and easy re-supply. It carries the manufacturer's warranty; the valve, vessel, refill media and compatible hoses remain available in the catalogue to support the installation throughout its service life.
