Production Of Red Mud Composite As Coagulant For Harvesting Chlorella Vulgaris.
Masters thesis, Universiti Sains Malaysia.
Abstract
Red mud is a solid waste which is insoluble and has high alkaline content that is produced during alumina extraction from bauxite using Bayer process. The most common way used to dispose the red mud is by dumping it into large pond within the secured places. But the biggest concern regarding this method it does create pollutions due to high alkaline content and presence of heavy metals in red mud. This study will focus on the feasibility of developing composite coagulant from red mud by using acid leaching method which consists of acid leaching, hydrolyzation and polymerization.
