Industrial Wastewater treatment technology

Although the conventional methods like, coagulation / flocculation, sedimentation, filtration, and disinfection are promising for the industrial waste water treatment, some of the chemical pollutants cannot be eliminated using such methods, hence the need to use integrated advanced treatment process technologies. The task of selecting the best treatment option for remedying specific industrial water is usually a complex one. EIS conduct pilot-plant studies at the client facility and such studies prove decisive in cases where several technologies are to be combined for reuse or decontamination of particular industrial spent water. EIS selection of the specific wastewater technology to apply include the quality of spent water, conventional treatment options, removal of contaminants, treatment flexibility, economic studies, the facility decontamination capacity, treatment system efficiency, reuse of treated water and the compatibility of wastewater treatment technology.

Currently, Electro coagulation (EC) and advanced oxidation processes (AOPs) are among the most frequently used approaches to remove pollutants that have low biodegradability or high chemical stability. These methods is depend on the generation of hydroxyl free radical (HO*) as a strong oxidant for the destruction of compounds which cannot be oxidized using conventional oxidants. Hydroxyl radicals, which are non-selective reactive species, able to oxidize pollutants into mineral end-products, yielding CO2 and inorganic ions.
