Innovative Water Treatment

Clean TeQ water treatment solutions are built around the three core technologies: CIF® Continuous Ionic Filtration, NeX™ Natural Evaporation and Cystallisation Technology and advanced membrane systems

Continuous Ion Exchange – CIF®

Contaminants in water can be effectively removed using a combination of physical and ionic filtration.

Process Description

Feed water is passed upwards through the ionic bed and exits the top of the filter as cleaned water. At the same time, the resin is removed from the bottom, cleaned, regenerated and returned to the top.


Clean TeQ’s Continuous Ionic Filter (CIF®) offers the following benefits:

  • Operates on Dirty Feed Waters
  • Operates on Variable Quality Feed Waters
  • No Scaling & Fouling Issues
  • Potential Value in By-Product Recovery
  • Low Capital Cost
  • Low Operating Cost
  • Fully Automatic

 Case Example

Clean TeQ has shown the effectiveness of the technology in multiple applications including municipal, groundwater, mining and power. A demonstration plant located in Queensland Australia processed 200 tonnes of saline ground water per day to recover over 95% of the water as irrigation quality for crops and producing a gypsum by-product for soil improvement


NeX™ – Natural Evaporation and Crystallisation 

High salinity water can be treated by NeX™ to create high purity distilled water and a solid residue by-product.

Process Description

Highly polluted, high salinity (>5%) waste streams are fed into a low temperature, ambient pressure humidification chamber where water is evaporated by a dry air stream. Subsequently, the evaporated water is recovered, together with the heat energy in a dehumidification chamber. This process results in clean distilled water and semi-dry salts produced at low energy cost.


The low-temperature evaporation process reduces the risk of scaling and can handle a wide range of input streams that can include COD and volatile elements that tend to create major obstacles in traditional evaporation systems that boil the waste water.

The benefits of the NeX™ technology include:

  1. Zero liquid discharge
  2. Applicable to the most highly polluted waste streams
  3. Low energy use
  4. Rarely scaling problems

Case Example

In the treatment of desulphuration wastewater from coal fired power generation, NeX™ technology has shown to be a robust and cost-effective zero liquid discharge solution, with very low energy cost.  Beyond power generation the NeX™ technology has shown to be effective in many other industrial sectors.


 CleanBio® Lenses

CleanBio® is using natural bacteria immobilized in a PVA gel, which ensures waste water treatment processes are accelerated with as a result a lower footprint, low power and less sludge production. This process is particularly applicable nitrification and denitrification

Process Description

Biocatalyst is entrapped in a biolens made from a PVA matrix and the biolenses are stirred into a reactor. Diffusion of water and pollutants through the biolenses will result in the targeted reactions to occur.


  1. Less/no secondary waste/sludge
  2. No organism loss
  3. Ability to reach very low TN levels
  4. Intensified Process with a small footprint
  5. Low energy demand
  6. Low lifecycle costs
  7. Bacteria in biolens are protected against harsh water conditions

Case Example

Clean TeQ has designed two drinking water plants that use the CleanBio lenses for denitrification.

Advanced Membrane Systems

Membranes are universally used for filtration of waters and wastewaters in circumstances where the water quality is predictable and scaling and fouling potential is managed by pre-treatment.

Process Description

Clean TeQ provides the full range of membrane systems based on available membrane technology. Clean TeQ is also developing a novel membrane-based on graphene oxide that will require less energy in operation and avoids many of the scaling and fouling issues of conventional membranes

Case Example

Clean TeQ has designed and supplied a commercial ultrafiltration and ion exchange plant located in Queensland Australia cleaning treated wastewater effluent from an ammonium nitrate manufacturing process. The plants treat 1500 tonnes of process water per day to recover over 95% of the water as high-quality water for reuse in the boilers and cooling towers.
