Potential Utilization of Sewage Sludge from Water Treatment Plant as Brick Material

Abstract

One of the results of the water treatment process is the sludge. Generally, the processed sludge from the water treatment is collected and delivered to a landfil. With the delivery of sludge waste, it requires additional cost as a levy in handling sludge waste. Therefore, it is needed to innovate on the recycling of sludge. The waste recycling process is expected to minimize the residual impact of the Water Treatment Plant. The process of waste recycling can be done by utilizing sludge from water treatment, which is brick making process. The benefits can eliminate environmental problems and also some economic problems. This study aims to determine the potential of sludge from water treatment plant to be added for brick making by investigating the physical and characteristics of sludge. The research findings show that sludge waste has the potential to become a brick raw material depending on the nature and clay microstructure.
