Uranium In Water

Uranium is a common naturally occurring radioactive element found as part of rocks, soil, air and water. It enters surface water or groudwater by leaching from soil and rocks, or from industry sources such as tailings dams in the mining industry. Uranium can have a severe effect on human health, being toxic to kidneys and potentially causing an increased risk of cancer over a long period of time.

For this reason, the World Health Organisation’s guideline for drinking water is a maximum uranium concentration of 0.030 mg/L. After the uranium has been removed the waste can be difficult to deal with, often requiring radioactive materials handling permits and requiring careful disposal.

Uranium Removal Technologies

Our CIF® (continuous ionic filtration) technology can be used to reduce or remove uranium, using a strong base anion exchange resin to target uranium ions. The process uses physical filtration alongside ion exchange, which has the added benefit of removing other impurities in the feed water, and delivering higher removal efficiencies than conventional batch ion exchange systems. It is a robust system that usually doesn’t require pre-treatment, and has a reduced capital and operational expenditure through the more effect use of chemicals.

Clean TeQ Water also has a long history providing batch ion exchange plants to remove uranium from drinking water, with some plants still operating over 8 years since commissioning.
