Innovative methods are continuously required in water purification of a wide range of wastewater pollutants especially in case of difficult approach, then several technologies have been developed for example, Electrochemical Wastewater Treatments. Electrocoagulation system optimised by INTECNA, provides a relatively compact and robust wastewater treatment plant alternative in which special alloy metal anodes initiate electrochemical reactions that provide active metal cations for coagulation and flocculation. INTECNA has designed, developed and patented specific electrocoagulation plant for wastewater under the CELDAR brand.
