Electrochemical Technology Applied In Treatment Of Wastewater And Ground Water

With a rapidly growing economy and burgeoning populations, the world's scarce water resources, such as rivers and lakes, are seriously affected by pollution from the vast discharges of industrial and domestic wastewater, indiscriminate solid waste disposal and runoff from an agricultural sector characterized by excessive use of fertilizer and pesticides and large-scale livestock breeding. Therefore, these wastewaters must be treated before being discharged. The electrochemical method is an attractive alternative to other methods of wastewater treatment because of its environmental respectability and ease of operation. This book introduces the application of the electrochemical method for treatment of domestic and industrial wastewater.
