Water Treatment Technologies

Clean TeQ Water’s innovative water treatment technologies are specifically developed to solve some of today’s most pressing water issues. These include increasing the rate of recycling from waste water treatment plants in dry areas, treatment of highly polluting brine streams, and reduction of nutrient loads in effluent to prevent algae blooms and subsequent ecological dead zones.

Our water treatment technologies focus on three core areas, continuous ion exchange, biological treatment and evaporation/crystallisation. Our technology portfolio allows us to deliver tailored solutions to customers in a wide range of applications.


CIF® (Continuous Ionic Filtration)

CIF® enables contaminants in water to be effectively removed using a combination of physical filtration and ion exchange. The technology is continuous, and allows for direct treatment of variable quality input waters and compensation for variable produced water requirements. It is highly resistant to scaling and fouling, and can directly capture solids and dissolved ions typically without pre-treatment. Low capital expenditure, low power requirements and high recoveries are also features of our CIF® technology.

DESALX® (Membrane Free Desalination)

DESALX® consists of two CIF® modules in series, removing both cations and anions from water. DESALX® is used to perform efficient removal of hardness and sulphate from water, also providing TDS reduction. It can also be paired with high density sludge (HDS) systems to provide zero liquid discharge (ZLD) with low operational cost.

HIROX® (High Recovery Reverse Osmosis)

HIROX® combines our CIF® technology with reverse osmosis (RO) to provide a low cost, highly effective water treatment process. CIF® removes cations such as calcium and magnesium from the water, which are usually responsible for the scaling that occurs on RO membranes at high recoveries. With these cations removed, the HIROX® system achieves much higher water recovery (typically 95-99%). The brine from the RO is used to regenerate the ion exchange resin, providing a low cost, chemical free pre-treatment.

BIOCLENS™ (Encapsulated Bacteria Lenses)

Our BIOCLENS™ lenses contain encapsulated bacteria, which are immobilised in a stable, porous PVA gel matrix. The lenses are capable of removing ammonia and nitrate from water, and the encapsulation protects the bacteria in harsh environments (such as high ammonia/nitrate concentrations or saline water). Lenses have a higher bacteria biomass than conventional sludge, which allows smaller site footprints and ultra low (< 1ppm) nutrient concentrations to be achieved.

BIONEX™ (Complete Nutrient Removal)

BIONEX™ uses ion exchange resin to remove nitrate from the water, and then treats the nutrients in the brine using BIOCLENS™. Using ion exchange to remove and concentrate the nitrate allows consistently low nitrate levels to be achieved (as low as <1ppm in all conditions). Since the saline brine is treated using BIOCLENS™ it can be reused, providing minimal chemical consumption and waste production.

EVAPX™ (Low Energy Evaporation)

High TDS water/brine can be treated by EVAPX™ to create distilled water and a solid residue by-product. Waste streams are fed into a low temperature, ambient pressure humidification chamber where water is evaporated using a dry air stream. EVAPX provides reduced heating costs and is highly resistant to scaling, making it a highly efficient way to achieve minimum or zero liquid discharge (ZLD).

CLEAN-IX® (Metal Recovery)

Our CLEAN-IX® continuous ion exchange process provides highly efficient extraction and purification for a range of valuable and strategic metals from slurries and solutions. This includes metal recovery from clarified solutions, slurries, tailings, and water affected by acid mine drainage. CLEAN-IX® typically achieves an extraction rate of more than 98% of the contained metal in the solution, providing shorter payback periods than conventional processing flowsheets and making metal recovery from dilute streams economically viable.
