Clean TeQ designs for Koumala water treatment plant in Queensland

Mackay Regional Council

Clean TeQ has won a competitive tender and been awarded a contract which is valued at over $2 million by Mackay Regional Council for the upgrade of a bore water treatment plant at Koumala, near Mackay in Queensland.

Clean TeQ will design, supply, and install an ion exchange treatment plant plus a package gas chlorination system to remove hardness and lower the salinity of an

existing bore water supply to reduce the scaling of pipes and improve taste for use in the potable water supply of Koumala, Queensland. Clean TeQ will manage the full design, procurement, construction and commissioning of the plant including subcontracting of civil works. The program of works is scheduled to commence in the first quarter of CY2021 and run through to the end of the year.

Oman

In late 2019 Clean TeQ announced the successful customer acceptance of commissioning and handover of a ground-breaking Continuous Ionic Filtration (CIF®) plant in Oman. Clean TeQ was engaged by Multotec, the Company’s sales and delivery partner in Africa, under a design, procure and construct contract to deliver a waste water treatment system at an antimony processing facility in Oman. The Clean TeQ designed and supplied water treatment plant comprises the Company’s DESALX® (two-stage CIF®) technology, chemical precipitation and reverse osmosis to recycle process water for re-use on site. The water treatment plant is designed to remove a range of deleterious elements from up to 200 tons of waste water per day.

By treating the waste, the customer is able to recycle a significant proportion of the water for re-use in their processing plant, rather than disposing of it. This provides a valuable cost saving for the customer in a geographic location where water is relatively scarce. Recycling the water also results in environmental benefits by significantly reducing the volume of waste which would otherwise need to be disposed.

The plant consists of a number of precipitation steps to remove antimony, arsenic and hardness, followed by Clean TeQ’s proprietary DESALX® (two-stage CIF®) technology system to extract calcium and magnesium sulphate plus any remaining heavy metals, followed by reverse osmosis to desalinate the water and prepare it for re-use.

Clean TeQ has been awarded a contract to undertake the detailed design for an upgrade of this water treatment plant. Changes in the upstream antimony processing facility have resulted in a higher salt load and increased arsenic, antimony and selenium concentrations in the waste water. The upgrade will focus on neutralising the waste liquors and precipitating contaminants for easier recovery, as well as upgrading the existing ion exchange circuit using Clean TeQ’s CIF® technology and adding additional pre-treatment for the reverse osmosis plant in order to maximise recovery and generate reduced brine for disposal.
