Mixed Bed De-Ionized Water System

Sabah Water Filter Industries (SWFI) delivers reliable mixed bed de-ionized water systems for industries in Sabah and Malaysia. Our systems polish water to ultra-pure levels, removing nearly all dissolved ions for high-quality demineralized (DI) water.
These systems work best after reverse osmosis (RO). They help factories, pharmaceuticals, power plants, and petrochemical plants achieve clean, reliable water.

MIXION® module mainly used in the water purification industry for polishing process water to achieve demineralized water quality.
Mixed bed as the name states consists of strong acid cation exchange and strong base anion exchange resin.
Ideally used after RO permeate for polishing or direct from city water for demineralization.

Our systems deliver reliable, cost-effective water purification tailored to demanding sectors:

Frequently Asked Questions (FAQ) – Mixed Bed De-Ionized Water System

1. What is a mixed bed de-ionized water system?

A mixed bed de-ionizer uses a single vessel with both cation and anion exchange resins to remove almost all dissolved ions from water, producing ultra-pure demineralized (DI) water with high resistivity (>18 MΩ·cm). It is commonly used for polishing after reverse osmosis (RO) or directly on city water.

2. What industries in Sabah use mixed bed de-ionizers?

Common applications include:
– Pharmaceuticals
– Power generation plants
– Petrochemical and refinery plants
– Micro-electronics cleaning
– Condensate polishing for boilers
– Ultra-pure water production in manufacturing

3. How does it differ from a two-bed de-ionizer system?

A two-bed system uses separate cation and anion vessels, while a mixed bed combines both resins in one tank. Mixed bed systems produce higher purity water in one pass and are ideal for polishing RO permeate.

4. What is the capacity range of your MIXION® mixed bed system?

Our systems range from 2 m³/hr to 20 m³/hr, with custom sizes available based on your Sabah factory or plant requirements.

5. How does regeneration work?

Regeneration is automatic or manual: Backwash → Settling (resin separation) → Alkaline drawing → Acid-alkaline drawing → Acid-alkaline rinse → Drainage → Mixing → Rapid rinse → Fast rinse This upflow process ensures efficient resin cleaning and reuse.

6. What are the main benefits of your system?

– Saves at least 30% compared to portable DI columns
– Fully automatic with programmed controller
– 5-year warranty on FRP pressure vessels
– Skid-mounted, expandable, and easy to maintain
– Made in Malaysia with local support in Sabah

7. Can I combine it with reverse osmosis (RO)?

Yes – our mixed bed system is designed to polish RO permeate for ultra-pure water. We offer complete integrated RO + mixed bed solutions for Sabah industries.

8. How much maintenance is required?

Very low – the system is pre-wired, pre-plumbed, and individually tested. Components are easily accessible, and we provide local servicing in Sabah.

9. Is this system suitable for Sabah’s water quality?

Yes – it handles typical Sabah raw water or city water effectively. We customize pretreatment (multimedia + activated carbon filters) based on your local water analysis.
