TECHNOLOGY Feasibility Study of Electro-Coagulation as a Treatment Method for Textile Industry Wastewater

Electro-coagulation (EC) is becoming a popular process to be used for industrial wastewater treatment. In the present study, a laboratory scale electro-coagulation (EC) process was utilized to treat the textile wastewater in order to bring the quality up to the wastewater reuse standards and also to compare the electro-coagulation process with the conventional coagulation treatment. Effect of various operating parameters such as operating time and voltage on COD removal efficiency was evaluated to achieve the maximum possible treatment efficiency

TECHNOLOGY Plasma Gasification of Municipal Solid Waste: A Review

Utilization of plasma gasification in waste to energy is one of the novel applications meeting todays need for waste disposal. In this application, plasma arc, gasifies the carbon based part of waste materials such as municipal solid waste, sludge, agricultural waste, etc. and generating a synthetic gas which can be used to produce energy through engine generators, gas turbines and boilers. The non-carbon based part of the waste materials can be vitrified into glass and reusable metal. The analysis indicates that gasification is a technically viable option for the solid waste conversion, including residual waste from separate collection of municipal solid waste. The paper focuses on plasma gasification technology for waste disposal and energy generation with case study. It is able to meet existing emission limits and can have a remarkable effect on reduction of landfill disposal option
