QUATTRO™ - pure water in a package

QUATTRO™ systems supply high purity water for a range of applications.


QUATTRO™ systems supply high purity water for a range of applications.

Nominal flow rates from 500 to 3000 l/hr.

QUATTRO™ is a convenient and cost-effective solution for supplying up to 3000 l/h of high purity water (less than 0.7µS/cm conductivity). It combines in a single compact skid-mounted assembly four treatment processes:

  • softening
  • filtration
  • reverse osmosis (RO)
  • continuous electro de-ionisation (CEDI)


QUATTRO™ systems are fully pre-assembled and pre-tested before delivery, ensuring that installation is a virtually "plug-and-play" process, saving more time, and guaranteeing the minimum of on-site disruption.



Save Time

  • Pre-assembled and pre-tested
  • 'Plug and play' on site, so minimum site disruption
  • Fast track project delivery
  • Microprocessor control system with HMI screen - fast start up time and easy to use


Save Space

  • Skid-mounted
  • Footprint optimisation
  • Integrated Cleaning in Place system


Save Money

  • Reduced installation time
  • Chemical free, reducing running costs



The QUATTRO™ packaged water treatment solution provides appropriate purified water to various industrial fields :

  • Industrial laboratories
  • Biotechnology
  • Pharmaceuticals products
  • Cosmetics
  • Healthcare
  • Microelectronics
  • Boiler feed


A wide range of configuration options are available for QUATTRO™ systems, enabling them to be accurately matched to meet your requirements.



1- Softening
Softener columns pre-condition the process feedwater by removing water hardness due to calcium and magnesium ions.

The pre-filter step serves to extend the lifetime of the reverses osmosis membranes by capturing any fines particulates.

3- Reverse osmosis
The pretreated water enters then into the RO membranes. In addition to removing microbial impurities, the RO phase removes up to 97% of dissolved inorganics and over 99% of total dissolved organics, colloids and particles.

4- Continuous Electro-deionisation (CEDI)/Service Deionisation (SDI)
The final polishing step is done through CEDI or SDI process. The CEDI is an electrically driven, ion exchange technology combined to ion selective membranes, which operates continuously without chemical regeneration.
The SDI is the use of mixed bed ion exchange cylinders which are replaced and regenerated off-site.
