Elentec has developed a system of electrocoagulation for the treatment of contaminated water which has been trialled across a range of industries. These include removal of phosphate and ls from automotive plant waste as well as heavy ls from mine waste and contaminants and solids from groundwater. In particular we have removed phosphate from dairy waste and participated in projects to recover the phosphate; we are also working with the anaerobic digestion industry to deal with the effluent produced, as well as the capability of dealing with the slurry directly.

The technology replaces traditional chemicals used for coagulation, which are usually ferric or alum d, by the use of l plates within purpose designed chambers, where low levels of electrical current causes dissolution of the plates into the waste stream, which leads to coagulation prior to subsequent settlement. Advantages are: small footprint;low power requirement - some applications could be powered by photovoltaic;no chemical use or storage;significantly reduced sludge;flexible in terms of flow rates and modular design.
