The Governmental Institute for Sewage and Waste Water Treatment has studied the presence of a number of hazardous substances, selected by the EEC-Commission, in sewage and industrial waste water. The influent, effluent and sludge of six municipal waste water treatment plants and the waste water of 59 industries were sampled and analysed. Volatile chlorinated hydrocarbons in sewage originate mainly from industrial discharges. Chlorophenols, γ-hexachlorocyclohexane, polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAH) appear to be present at a low and constant background in municipal sewage and in many industrial waste waters. The removal in the municipal treatment plants amounts to:-volatile chlorinated hydrocarbons 50–90%-hexachlorobenzene 95%-hexachlorocyclohexanes 40–65%-chlorophenols 20–40%-PCB about 90%-PAH 85–95% This study has given a survey of emissions of these hazardous substances. The total emission of the examined substances in the Netherlands has remained out of the scope of this investigation.

Electrocoagulation Process

Waste water treatment by industry usually uses chemicals that may lead to additional environmental pollution load. On the other hand, water demand increases and environmental regulations regarding waste water disposal requirements that apply more stringent. It is necessary for waste treatment technique that accommodate this requirement. Electrocoagulation process is a technique of wastewater treatment that has been chosen because the technique is environmentally friendly. This paper will review some of the research or application electrocoagulation process which is conducted on industrial waste water. Types of industrial waste water that is to be reviewed include: industries batik, sarongs, textiles, palm oil, slaughterhouses, food, leather tanning, laundry, pulp and paper. Overview reviewed in this research include the waste water treatment process in several processing variations such as: change in time, electricity and kind of electrodes. The results of the research with electrocoagulation process in the industry are the removal efficiency of TSS, COD, BOD5, Chrome, phosphate, surfactants, color turbidity influenced by several factors including time, strong current, voltage, distance and type of electrode and pH. The results of the study with electrocoagulation process in the industry is the removal efficiency of TSS, COD, BOD5, chromium, phosphate, surfactant, turbidity color that are influenced by several factors including time, strong current, voltage, distance and type of electrode and pH. It is hoped the information presented in this article can be a reference for similar research for the improvement of research on the process ektrokoagulasi.Key words: elektrocoagulation, removal eficiency, environmental friendly
