A common effluent treatment waste water sludge being largest industry in India faces problem of sludge disposal. In this attempt is made to reuse common effluent treatment waste water sludge in solid blocks. Common effluent waste water sludge is used to replace base material by weight up to 15%. Blocks are casted by adding sludge after drying at 100 0 C to 150 0 C for 24 hrs. Common effluent treatment waste water sludge can be added up to 15% as it can give compressive strength above 8.33 N/mm 2 and water absorption ratio can be obtained as less than 0.50 %. Thus reuse of common effluent treat...
A common effluent treatment waste water sludge being largest industry in India faces problem of sludge disposal.

Common effluent treatment waste water sludge can be added up to 15% as it can give compressive strength above 8.33 N/mm 2 and water absorption ratio can be obtained as less than 0.50 %. Thus reuse of common effluent treatment waste water sludge in solid block is better option so that problem of ultimate disposal of common effluent treatment waste water sludge can be solved up to greaterextent.The overall objective of this study is to find an alternative solution for the disposal oflarge volume of sludge produced in the wastewater treatment plants. This large quantityof sludge is related to scarcely of land area and high population density represent thesludge problem.
