Description
PUROLITE MB400 is a mixed ion-exchange bed for final water demineralization after the RO process. It works well as a cartridge for reverse osmosis systems, osmotic filters, and reverse osmosis units when the goal is to obtain water with very low mineral content. The resin removes cations and anions simultaneously, is ready to use immediately upon delivery, and is packed in an airtight zip bag. It is a practical solution for applications where high water treatment quality and stable operation of the final filtration stage matter.
PUROLITE MB400 – mixed bed for water demineralization
PUROLITE MB400 is a high-quality ion-exchange mix designed to remove anions and cations after reverse osmosis filtration. The bed operates as a final stage, helping to obtain water with very low mineral content where the reverse osmosis filter alone is not sufficient to achieve the expected water purity.
The resin has the form of transparent, yellow, spherical granules. The properly balanced ratio of cation resin to anion resin, 1.0 : 1.5, supports effective capture of positive and negative ions, making the bed suitable for precise demineralization in water filtration systems and installations requiring water after final polishing.
Application and key benefits
The PUROLITE MB400 bed is intended for final water demineralization after RO. In practice, this means effective polishing of water after it passes through the reverse osmosis system, so as to limit the presence of residual ions and achieve an even lower mineral content.
- removes cations and anions simultaneously,
- supports obtaining water with very low mineral content,
- is suitable for post-reverse-osmosis operation as a final stage,
- is supplied in H+ / OH- ionic form,
- comes in convenient packaging and is ready to use,
- works well as an MB20 replacement in demineralization applications.
Bed characteristics
PUROLITE MB400 is an ion-exchange mix based on polystyrene cation resin and anion resin. The granules have a spherical shape and a yellow, transparent form, which makes it easier to identify the material when filling columns or cartridges intended for demineralization.
An important operating parameter is the ratio of bed components: cation resin : anion resin = 1.0 : 1.5. Such a composition promotes effective removal of both positive and negative ions from water, which is crucial at the final stage of treatment.
Operating conditions
To ensure the bed retains its proper operating properties, it is worth following the basic operating parameters. These concern operating temperature, bed depth, and flow rate depending on the type of water supplied.
- maximum operating temperature: 60 °C,
- minimum bed depth: 700 mm,
- flow rate for raw water: 10–20 BV*/h,
- flow rate for partially demineralized water: 20–40 BV*/h.
* BV (bed volume) = 1 m³ of solution per 1 m³ of resin.

Packaging and ready-to-use form
The product is packed in an airtight zip bag, which makes storage and convenient dosing easier when preparing a cartridge or topping up the bed in the device. The package capacity is 1 liter, i.e. 1,000 ml. The delivery format allows quick use of the product without any additional packaging preparation.

FAQ
What is PUROLITE MB400 used for?
PUROLITE MB400 is used for final water demineralization after reverse osmosis. The bed removes cations and anions simultaneously, helping to obtain water with very low mineral content.
Is this bed suitable for use after an RO system?
Yes, this product is intended specifically for use after reverse osmosis filtration. It can be used as the final water polishing stage in RO systems.
What form does MB400 resin have?
The bed comes in the form of yellow, spherical granules. The technical description also states a granule size of 0.3–1.2 mm.
Which ions does this mixed ion-exchange bed remove?
PUROLITE MB400 removes both positive ions, i.e. cations, and negative ions, i.e. anions. This makes it suitable for final water demineralization.
In what ionic form is the bed supplied?
The resin is supplied in H+ / OH- ionic form. This is a ready-to-use form typical of a mixed bed designed for demineralization.
What are the recommended operating parameters for this bed?
The maximum operating temperature is 60 °C, the minimum bed depth is 700 mm, and the flow rate is 10–20 BV*/h for raw water and 20–40 BV*/h for partially demineralized water.
What does the unit BV*/h mean?
BV stands for bed volume. 1 BV equals 1 m³ of solution per 1 m³ of resin. This parameter helps define the recommended flow rate through the bed.
How is the product packaged?
The product is packed in an airtight zip bag. This packaging makes storage easier and allows convenient use of the bed when filling a cartridge or tank.
Can PUROLITE MB400 be used as a replacement for MB20?
Yes, the product is offered as a replacement for MB20 in water demineralization applications.
Niezawodna ż ywica MB400
Swietna mieszana zywica demineralizujaca. Uzywam w systemie odwrconej osmozy do akwarium. Woda jest krystalicznie czysta, parametry w normie. Latwa wymiana, opakowanie szczelne i dobrze zabezpieczone. Polecam akwarystom i do zastosowan laboratoryjnych.
