Where We Use Our Technology

Municipal Waste Water


Municipal wastewater treatment plants are being regulated to meet to meet stringent specifications for discharge in relation to Chemical Oxygen Demand (COD), total nitrogen (TN) and total phosphorus (TP) levels. Meeting these criteria requires the use of advanced biological and membrane processes which can result in much larger plant and increased power requirements for aeration and pumping; these improvements are often difficult to implement and expensive. Moreover, in colder climates or during winter seasons, the effectiveness of biological treatment can go down substantially, which can also result in the treated effluent exceeding required discharge standards.

Clean TeQ’s CIF® technology provides an excellent solution. CIF® can directly treat the overflow from the secondary clarifiers and reduce the levels of COD, TN and TP to meet the most stringent discharge standards.

CIF® uses a hybrid ion exchange system to polish the secondary effluent by removing COD, ammonia, nitrate and phosphate. The tertiary treated water can then be used in many applications including surface discharge to rivers, recreational lakes or industrial processes.

Where desalination is a requirement, CIF® provides an excellent pretreatment for high recovery reverse osmosis (HiROx™).

The capital and operating costs of a CIF® tertiary treatment plant provide a very attractive cost of ownership.

Power Generation


The handling of power plant water and wastewater is becoming increasingly complex as the regulations move to Zero Liquid Discharge (ZLD) by 2020.

The latest technology to achieve ZLD in power plants involves the following unit processes:

  • Lime Softening
  • Multimedia filtration
  • Ion Exchange Polishing
  • 2-stage Reverse Osmosis
  • Forward Osmosis
  • Evaporation & Crystallisation

CIF® technology directly treats the FGD wastewater and replaces the lime softening, multimedia filtration, ion exchange polishing steps with high water recovery. Achieving 50% cost reduction

High recovery reverse osmosis can then recover most of the remaining water for re-use.

Finally, Clean TeQ’s NeX™ technology can treat the highly concentrated brine from reverse osmosis to provide zero liquid discharge (ZLD) outcome for power plants. By re-using the waste heat from the power plant the operational cost of this solution can be very low.



CIF technology filters and cleans mining process and wastewater to enable the water to be reused or disposed to the environment and to recover valuable metals.

Mining waters are contaminated with metals, acids, and sulphates. CIF® extracts the metals and sulphates to allow the water to be reused or disposed of and to recover the metals.

CIF® can be designed to provide a zero liquid discharge (ZLD) outcome when combined with the NeX™ natural evaporation technology

The capital and operating costs of a CIF mining water treatment plant are highly attractive especially in areas that are fresh water stressed.

Bulk Chemicals


Large scale chemical plants such as refineries and coal to chemical plants consume a large amount of water and create large volumes of difficult to treat wastewater. Water scarcity and concerns about pollution often result in very strict discharge requirements and zero liquid discharge.

Clean TeQ’s NeX™ evaporation and crystallisation technology is well suited to treat this highly polluted wastewater reaching over 99% water recycling and returning crystallised salts that can sometimes be re-used.
