Based on technologies developed at The University of Queensland, Cloevis is a new, low-cost and effective method of preventing sewer corrosion and odours caused by hydrogen sulphide. Sewer corrosion is a world-wide problem, arising from bacterial sulphide formation, particularly within the biofilm on the inner surface of pipes. Oxidised sulphide forms sulphuric acid, which corrodes concrete sewer pipes. Current chemical treatments target the hydrogen sulphide, which requires continuous dosing. Cloevis is a two-part solution - a patent-pending chemical mix to effectively kill sulphide-producing bacteria and a software modelling tool for optimising dosage - offering the potential to reduce treatment costs significantly.
