The last stage of upgrades to two wastewater treatment plants will begin after Cairns Regional Council announced an investment to replace specialist filtration membranes.
Council will spend $6,297,963 to replace specialist filtration membranes in the northern and southern wastewater treatment plants by the end of the 2022/23 financial year.
The membrane replacement is the final stage of a six-phase project to upgrade the treatment plants.
Council has systematically replaced the synthetic mineral fibre membranes over the past three years to maximise the lifespan of the filters, reduce the risk of equipment failure and subsequent environmental impacts, and minimise the cost to ratepayers.
The specialist filters, recommended by the Cleaner Seas Alliance, provide a high level of effluent polishing including removal of nitrogen, phosphorus and potentially harmful bacteria all without the need for unsafe chemicals
