Résine Purolite MB400 IND, lit mélangé industriel, ref. MED-PUROLITE-MB400IND

Overview

The ion-exchange resin (ref. MED-PUROLITE-MB400IND, sac de 25 L) is a bead-form medium that selectively captures certain water ions. Depending on the type (cationic for softening, anionic anti-nitrate, or mixed-bed for demineralisation), it exchanges calcium/magnesium for sodium, retains nitrates, or produces demineralised water. Loaded into a softener or demineraliser bottle, it regenerates (salt or reagent) for a long service life.

Role & action

This medium provides ion exchange, softening, demineralisation or nitrate removal depending on the resin. Its performance depends on the loaded volume, the service flow and the quality of the water to be treated. It fits into a filter bottle equipped with a valve (manual or automatic) or into a suitable media holder, sized to your installation’s flow.

Commissioning & maintenance

Load the medium into the bottle (with a support layer if needed), backwash before first commissioning to remove fines, then put into service. Depending on the medium type, periodic backwash declogs the bed and restores the pressure drop; adsorbing media (carbon) and finite-capacity media (arsenic) are replaced when saturated.

Packaging

Supplied as sac de 25 L. Store dry, protected from frost and contamination sources. Handle with suitable protective equipment (dust). Sized to the useful volume of the filter bottle.

Savings & ecology

A well-chosen, properly backwashed medium lasts several years and treats large volumes of water at low cost. Media regenerated by simple backwash (sand, glass, iron removal) limit consumables and waste; recycled filter glass and coconut carbons fit a sustainable approach. Less scaling, corrosion and clogging downstream also means a more reliable, economical installation.

Choosing right

Choose the medium according to the problem to treat (chlorine/taste → carbon; acidic pH → calcite/corosex/everzit; iron/manganese → BIRM/pyrolusite; arsenic → Bayoxide; turbidity → sand/glass) and according to your bottle’s flow and volume. Several media can be layered. The DIMM team helps you size the volume and choose the right valve.

Key specifications

DIMM service & support

DIMM distributes a complete range of filtration and treatment media, activated carbons (coconut, coal, agglomerated, catalytic), pH correctors (calcite, corosex, everzit), iron removal (BIRM, pyrolusite), arsenic removal (Bayoxide), filter sands and glasses, ceramic beads, plus the bottles, valves and mounting accessories. Our teams advise on choice and sizing by your water analysis, supply refills and handle follow-up. Every medium is identified by its article code for reliable ordering and easy re-supply.

Good to know

Always check the medium’s compatibility with your water analysis (pH, iron, hardness, flow). Rinse the medium before commissioning to remove fines. Provide a support layer (sand/gravel) under fine media and respect the expansion rate during backwash. Carbons and adsorbing media must be replaced once saturated, they do not regenerate by simple backwash.

Applications

These media equip domestic and industrial filter bottles, at point of entry as well as point of use: homes, buildings, shops, agriculture, industrial processes. They protect softeners, RO units, water heaters and networks, and improve water quality (taste, clarity, pH, iron, arsenic) depending on the chosen medium.

Warranty & re-supply

Medium distributed by DIMM and identified by its Business Central article code for reliable ordering and easy re-supply. Bottles, valves, support layers and complementary media remain available in the catalogue to build and maintain your treatment chain throughout its service life.
