Industrial Waste Water Treatment using Electrocoagulation
The electrocoagulation wastewater treatment is very interested in the present. Because the system requires less space and lower operating cost, when compared to other systems. Many studies have tested the effectiveness of wastewater treatment by this method in different manners. But mostly confined only in laboratory scale.[2-5] Some work can be done commercially, but must be imported from abroad. That is expensive and lacks of specialists to operate the system. For this reason, the electrocoagulation waste water treatment system has not been used prevalent in Thailand. Our research team is interested in creating a prototype wastewater treatment by this method, which can be used practically in Thailand.
The main problem in the system is corrosion and the formation of a hydroxide formed on the electrode. Therefore, it is necessary to regularly to clean the electrode in a reaction tank to provide effective treatment of wastewater is not reduced. That is the burden of maintenance. A solution to these problems can be achieved by creating a mechanical abrasion electrode in a reaction tank, which will be developed in next-generation.
