This book deals with quantification of bacterial pathogens from three landfills in Malaysia. The emphasis was to validate whether leachate contains pathogens against the common notion related to non-pathogenic potential of leachate. The use of chlorine was looked upon as a means of inactivation of bacterial pathogens and the effect of chlorine dosage, and contact time was studied on the inactivation pattern and formation of chlorination by products.

Mature leachate generated from an aged sanitary landfill is typically classified as non-biodegradable.Disposal of untreated landfill leachate can be a source of hazard to receiving waters. Therfore, treatment of landfill leachate is considered environmentally essential. The application of ion exchange process in landfill leachate treatment was not well established in literature. Optimized operational conditions and the interaction among process variables for this treatment process were unidentified, leaving a substantial gap in landfill leachate treatment knowledge. In the present work, the...
