The safe and efficient disposal utilization of sludge are major issues to be solved in solid waste treatment environmental protection due the complex characteristics low rate innocuous treatments. Composting is a process decomposing organic matter transformed low-molecular acids into high-molecular humus substances under action microorganisms. Although land-use after composting has become an im...

Present study was carried out to evaluate the feasibility of conventional rural based defluoridation technique Nalgonda technique, Activated alumina in urban areas. Nalgonda technique is being used extensively due to ease in construction of the reactor, operation & maintenance. This technique is very effective even when the fluoride concentration is above 20 mg/L. However, generation of acid or...

Sludge management has been regarded as an environmental challenge to deal with due high energy costs for wastewater treatment plants. From this perspective, of sludge should be defined and calculated in order obtain effective Energy consumption is the major constituent operational costs. Especially, dewatering processes have led electricity at industrial This paper aimed define role design para...
