The composition of landfill leachate is complex due to the conditions within a landfill and treatment methods must be based on the actual characteristics of the leachate. This book, therefore, investigates various operating conditions for minimizing required Fenton reagents and sludge disposal and maximizing chemical oxygen demand as well as colour removal from the leachate. A number of combined treatment processes are also developed in order to maximize the removal of organic compounds through the most appropriate one. Samples were collected from Matuail landfill site, one of the major...
