Anaerobic treatment of sludge, industrial waste water and industrial waste from food industry

The use of biological anaerobic treatment for sludge digestion in treatment plants has a Jong operational record. The result is a lower amount of stabilised sludge and a considerable energy output, as heat and possibly also electrical energy. In industrial waste water treatment, anaerobic processes have also been used quite a Jong period, especially in food and pulp and paper industries. The anaerobic treatment of organic waste from industries or municipal waste, is a more recent application. The paper presents a summary of used anaerobic technology, with a special case from the Kalmar waste water treatment plant, where the two existing sludge digesters are upgraded to termophilic anaerobic treatment, one unit t be used for sludge and the other, separately, for organic waste from food industry and manure from farms.

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
