KDF 85 Filter on Clack WS1TC Bottle 25 kg – ref. CLACK-WS1TC-KDF85-25

Overview

Bottle filter filled with KDF 85 redox media (copper-zinc), on Clack valve (ref. CLACK-WS1TC-KDF85-25). WS1 valve. This filtration unit removes iron and hydrogen sulphide at the point of entry to protect the entire installation. Supplied ready to install (filled bottle + valve + distribution), it treats mains water, well water or borehole water.

Filtration principle

KDF 85 media, a copper-zinc alloy, is optimised for removing iron and hydrogen sulphide (H2S, rotten egg odour) from well water. Through redox reaction, it oxidises these compounds into particles retained in the bed and removed during backwash, without chemical additives, whilst limiting bacteria and scale.

KDF85 media

The bottle is filled with KDF 85 redox media (copper-zinc) on a gravel/flint support bed that distributes water and retains fines. Media volume: 25 kg. Depending on the media, the bed is backwashed (carbon/Ecomix) or recharged when consumed (calcite/Corosex/Everzit), to maintain performance over time.

Valve & operation

The WS1 valve automatically controls cycles: service (filtration), backwash, rinse and return to service (and salt regeneration for Ecomix). Triggering is time-based or volume-based depending on the model; an integrated bypass isolates the filter without cutting off water.

Sizing & installation

Choose the size according to peak flow rate and water quality. Provide a drain outlet for backwash and electrical supply for the valve. Install in a frost-free location on level ground; an upstream sediment pre-filter is recommended to protect the media.

Economy & ecology

Treating water at the point of entry protects the entire installation: less corrosion (pH correction), more pleasant water (carbon) and preserved equipment, resulting in fewer replacements and less maintenance. Backwash uses only water (and salt for Ecomix), without polluting additives: effective treatment that respects the resource.

Choosing correctly

To choose correctly, have your water analysed (pH, TAC, chlorine, iron) and estimate peak flow rate. Media is selected according to need: carbon (taste/chlorine), calcite/Corosex/Everzit (pH correction), Ecomix (multi-parameter). The DIMM team will help you size the bottle, valve and pre-treatment.

Key specifications

DIMM service & support

DIMM designs, assembles and ships turnkey bottle filters (Aquacarb/Carbsorb carbon, pH correction Calcite/Corosex/Everzit, multilayer Ecomix) on Clack valves, as well as hoses and accessories. Our teams analyse your water, size the bottle and valve and advise you on suitable media and pre-treatment. Each reference is identified by its article code, with manufacturer warranty, spare parts and refill media available. From advice to commissioning, we support installers and end-users, from sizing the bottle and valve to selecting media and maintenance follow-up, with a stock of refill media and spare parts immediately available.

Good to know

Media is selected according to water analysis: carbon for taste and chlorine, calcite/Corosex to raise aggressive pH, Ecomix for multi-problem well water. Plan for backwash (sufficient flow rate and drainage) and, for pH correction media, periodic level monitoring and recharging as they are consumed. An upstream sediment pre-filter protects the media and extends backwash intervals, whilst regular water analysis allows valve settings to be adjusted.

Applications

These bottle filters are installed at the point of entry (protecting the entire house or building), in residential, commercial and agricultural settings. Depending on the media, they refine taste, correct pH or treat multiple parameters. They combine with sediment pre-filtration and, if needed, aeration, for healthy water and protected plumbing year-round.

Warranty & resupply

Unit assembled and distributed by DIMM, identified by its Business Central article code for reliable ordering and simple resupply. It benefits from manufacturer warranty; the valve, bottle, refill media and compatible hoses remain available in the catalogue to support the installation throughout its lifetime.
