Characterization of titanium oxide optical band gap produced from leachate sludge treatment with titanium tetrachloride.

This study investigated the coagulation performance of titanium tetrachloride (TiCl) for leachate treatment and preparation of titanium oxide (TiO) from generated sludge through calcination process at different temperatures and times. TiCl with chitosan as coagulant aid employed to perform coagulation process on Alor Ponhsu Landfill leachate. Further calcination process was done to synthesize TiO from produced sludge for photocatalytic applications.

Clinoptilolite augmented electrocoagulation process for the reduction of high-strength ammonia and color from stabilized landfill leachate.

The high-strength leachate produced from sanitary landfill is a serious issue around the world as it poses adverse effects on aquatic life and human health. Physio-chemical technology is one of the promising options as the leachate normally presents in stabilized form and not fully amendable by biological treatment. In this research, the effectiveness of natural zeolite (clinoptilolite) augmented electrocoagulation process (hybrid system) for removing high-strength ammonia (3,442 mg/L) and color (8,427 Pt-Co) from naturally saline (15 ppt) local landfill leachate was investigated.
