Use of arsenic contaminated sludge in making

2018-2-12 · ABSTRACT: Arsenic contaminated sludge can be substantially found from the treatment of arsenic contaminatedground water. Lake of proper management and reuse of this sludge can create further environmental problem as there isprobability of mixing with soil and water. In this paper, effort is taken in order to use of such waste. Here, effectivenessof using this sludge during the process of making ornamental brick has been analyzed and justified. The detailed studywas made upon the suitability of sludge in making bricks. Results of different tests indicate that sludge proportion isthe key factor for determining the quality of ornamental bricks/tiles. The compressive strength of ornamental bricksmutually decreases with increase of sludge proportion. This study showed that arsenic contaminated sludge could beused safely up to 4 % for making ornamental bricks. Because upper than this limit, the quality of bricks
