TitleStabilization of arsenic removal plant sludge by mixing in cement mortar
AbstractArsenic a semi-metallic element found naturally in ground water in some areas of India, Bangladesh, Italy, Chile, China, Argentina, Mexico, and many other countries. Due to differences in geochemistry, environmental conditions, and human activities, arsenic concentration in ground water aquifers varies widely which is several times higher than Maximum Contamination Level (MCL), 10?g/L as recommended by World Health Organization (WHO). Long-term exposure to arsenic through drinking water and/or food can results in adverse health effect Chronic Arsenic Toxicity (CAT). Different technologies are in use for removal of arsenic from portable water which generates higher concentration of arsenic mixed sludge. The safe disposal method of this arsenic rich sludge is of great concern as it possesses high potentiality of arsenic to leach back and mixed with ground water aquifers. Present research was conducted to address this issue and determine a simple and easy process for stabilization of this sludge by mixing in cement mortar. Numbers of standard cement mortar cubes were prepared with design mix ratio of arsenic sludge to evaluate its arsenic stabilization capacity. Standard physical and destructive tests were also carried out to ascertain there usability as construction materials.
