Anaerobic digestion is an engineered methanogenic decomposition of organic matter under oxygen-free conditions and involves a mixed consortium of different species of anaerobic microoganisms that transform organic matter into biogas. The process is successfully used for the treatment of municipal sludge, animal manure, industrial sludge, and industrial and municipal wastewaters. Applications of...

Laboratory scale studies were conducted to investigate the feasibility of Industrial by-products as potential alternative medium to conventional gravel in the drainage layer of leachate collection system as permeable reactive barriers (PRBs) for landfill leachate treatment. Industrial by-products were used to treat effectively the landfill leachate, which is an innovative in-situ remediation te...

This paper presents a forecasting study of municipal solid waste generation (MSWG) rate and potential of its recyclable components in Kuala Lumpur, the capital city of Malaysia. The generation rates and composition of solid wastes of various classes such as street cleansing, landscape & garden, industrial & constructional, institutional, residential and commercial are analyzed. The past and pre...

background: in addition to the various human environmental issues, environmental hazards due to the industrial waste mismanagement are one of the country's major problems. this especially is more important in the provinces such as bakhtiari province where there have been concentration and diversity of the natural resources and a rapid growth of technology and industry in the recent years. metho...

In this review, adsorbents used in wastewater treatment and their technical feasibilities are reviewed. Adsorbents are classified as natural adsorbents, and the adsorbents obtained from industrial and agricultural wastes. They all were compared with each other condensing the metal binding capacities, costs and metal removal performances in waste water treatments. Although commercial activated c...
