EFFLUENT TREATMENT PLANT EVALUATION KIT USING DIFFERENT ELECTRODES AS A ELECTRO COAGULATION & ELECTRO OXIDATION,

Electro coagulation operation and Electro Oxidation are the most important process in water treatment and frequently is a necessary units which cannot be omitted or substituted. The target of coagulation are the precipitation, colloidal and suspended particles which consist of insoluble and hydrophobic materials. Therefore, the attempt to remove soluble materials from water by coagulation directly is impracticable. If some soluble materials can be transformed to insoluble materials, they will be coagulated and flocculate in the top of the Coagulation Reactor. In some cases, soluble materials can be removed to some extent since they are adsorbed onto the flocculates formed in the coagulation process; and also some heavy metals settled in the bottom of the settling tanks, as a result, the co-precipitation will take place, which can be considered to be a synergy effect. Generally, the flocculates produced can be separated from water by settling, filtration, flotation, etc. The purpose of coagulation is not only to cause particle settling but also to give particles the appropriate surface property which facilitate particles to be retained by the filter medium in subsequent filtration unit. The aim of water treatment for the water supply is to provide drinking water for people and industrial water for production. In water plants for the water supply, surface water or underground water is treated to meet the standards of usage by people or the industry. The typical technological process includes natural sedimentation, coagulation, sedimentation, filtration, and disinfection. Also the important electrodes installed in the  Appraisal Kit are used to conduct the preliminary test as onsite test.  The same attached image is self-explanatory.
