Greensand Iron Removal Filter on Clack WS1CI 90 L Bottle - ref. CLACK-WS1CI-GREENSAND-90

Overview

Iron removal filter on Clack Greensand media (ref. CLACK-WS1CI-GREENSAND-90). 16X65 bottle. WS1 valve. This unit treats well, borehole or mains water laden with iron and/or manganese, which cause ochre deposits, stains on laundry and fittings, and metallic tastes. Supplied ready to install (filled bottle + valve + distribution), it is installed at the entry point to protect the entire system.

Iron removal principle

Manganese greensand is a media coated with manganese oxide that oxidises and retains iron, manganese and hydrogen sulphide. It acts by catalytic contact and regenerates periodically with potassium permanganate, allowing it to treat heavily laden water and high manganese concentrations.

Greensand media

The bottle is filled with Greensand media on a gravel/flint support bed that distributes water and retains fines. Media volume: 85.2 L. The media regenerates/cleans by backwash, which unclogs the bed and removes retained oxides, restoring filtration capacity for the next cycle.

Valve & operation

The WS1 valve automatically controls cycles: service (filtration), backwash, rinse and return to service. Depending on the model, triggering is time-based or volume-based. An integrated bypass allows the filter to be isolated without cutting off water. Programming adjusts to hardness/iron load and consumption.

Sizing & installation

Choose the size (16X65 bottle) according to peak flow rate and iron/manganese content. Provide a drain connection for backwash, electrical supply for the valve, and if water lacks oxygen, aeration or air injection upstream. Install in a frost-free location, on level ground, with sediment pre-filter recommended.

Economy & ecology

Treating iron and manganese at source prevents ochre scaling of pipework, stains on laundry and premature failure of appliances: equipment lifespan is extended and cleaning products and replacements are reduced. Backwash uses only water (and salt for Ecomix), with no polluting additives, for effective treatment that respects the resource.

Choosing correctly

To choose correctly, have your water analysed (iron, manganese, pH, dissolved oxygen, H2S) and estimate peak flow rate. Media is selected according to parameters: BIRM (oxygenated water), Greensand/Pyrolusite (heavy loads, manganese), Ecomix (multi-parameter + softening). The DIMM team will help you size the bottle, valve and pre-treatment.

Key characteristics

DIMM service & support

DIMM designs, assembles and ships turnkey iron removal stations (BIRM, Greensand, Pyrolusite, Ecomix media) on Clack, Fleck and Ecosoft valves, together with hoses and connection accessories. Our technical teams analyse your water, size the bottle and valve, and advise on appropriate pre-treatment (aeration, pre-filtration). Each reference is identified by its article code for reliable ordering, with manufacturer warranty, spare parts and replacement media available. Whether you are equipping a domestic borehole, agricultural operation or tertiary building, we support you from water analysis to media and valve selection, through to commissioning and maintenance follow-up of your unit.

Good to know

Catalytic iron removal (BIRM, Greensand, Pyrolusite) requires regular backwash and sufficient flow rate: undersizing the bottle degrades effectiveness. Check dissolved oxygen and pH before choosing media. For multi-problem well water (iron + hardness), Ecomix simplifies by treating everything in one bottle regenerated with salt. Also consider a sediment pre-filter upstream, drainage of backwash water and annual media inspection: these three practices preserve effectiveness and extend the unit's lifespan.

Applications

Iron removal applies to well, borehole and spring water laden with iron and/or manganese, in residential, tertiary and agricultural settings. Placed at the entry point, the unit protects the entire house or building: fittings, appliances, softener and reverse osmosis unit downstream. It combines with sediment pre-filtration and, if necessary, aeration to ensure the oxygen required by catalytic media.
