Hazardous Waste Treatment

V. HAZADOUS WASTE TREATMENT PROCESS Presently, the hazardous waste treatment technologies are highly developed from the decade before due to the more environmental and ecosystem concerning. Moreover, hazardous waste not threaten only environment but also to human hygiene and health. However, one of the most dangerous hazardous waste is dichlorodiphenyltrichloroethane (DDT). Addition, DDT is used as a majority pesticide during agriculture revolution period, and also uses to regulate Malaria in developing country and Africa. Meanwhile, DDT is banned after the research is found that DDT derivative, DDE, is a carcinogenic substance where able to accumulate in the food chain. As a result, DDT contain waste must be properly manage and destroy, so the conventional treatments available are categorized in to four main groups; Physical treatment, Chemical treatment, Biological treatment and Thermal treatment. A. Physical treatment

Physical treatment process is the process that design to separate and concentrate the component in the waste stream in order to immobilize the hazardous component. Moreover, the physical treatment processes not directly destroy hazardous waste; instead prepare the waste for further treatment or disposal. In addition, the traditional and conventional physical treatment processes are adsorption, filtration, and separation.

B. CHEMICAL TREATMENT Chemical treatment process is the process that utilize chemical reagent in order to convert the hazardous compound to be less toxic or non-toxic. Additions, chemical treatment process might also convert the hazardous substances to the stable compound for easily further treatment or disposal. However, the main benefit of chemical treatment is the production of by-product substance that can be further utilize in other process or saleable. C. Biological treatment

Biological treatment process is chiefly utilizing microorganism in order to degrade hazardous waste. However, biological
