Waste water treatment has become a big challenge to industries since conventional methods are unable to remove pollutants to acceptable levels. The main challenges in the treatment of tea wastewater are; colour, BOD and COD emanating from phenols present in green tea catechins. This book provides some understanding on electrochemical processes capable of removing colour, COD and BOD from tea wastewater. The method was optimized for total colour removal using specific energy consumption as the indicator while varying process conditions such as electrode gap, surface area to volume ratio,...
