Abstract

Many methods for dewatering of sludge, such as natural evaporate by sun or by means of equipment. Three kind methods of electroplating sludge dewatering by using equipment hare been studied, i.e : centrifugal, filter press and vacuum filter. The result shows that centrifugal has the best performance in term of reduction speed of sludge weight, moisture content of dry cake, and also time. The use of coagulant, thickener and polymerin dewatering can increase flock formation , therefore can accelerate the process. Coagulant addition is necessary in dewatering by using centrifugal method.

Abstract

Disposal of ex-dry cell is one of some waste which is potential for environmental pollution, because dry cell containt heavy metal and other material which is characteristic toxic.This research show the impact disposal of this dry cell. Result from lechate test show that heavy metal which is contained in dry cell shall be leachate in water, moreover in acid condition.

Abstract

The Function of stabilization is to decrease leachate or chemical reaction which is potential to produce pollutant from waste. Three kinds of stabilization such as addition of the cement, lime and organic sludge had been done before. The result showed that the sludge can bind heavy metal. Analysis result showed that the decrease 'in presentation of heavy metal are Zn (79%), Cu (83,5 %), Fe (99,97 %), Mn (JOO %) and Cr (98,2 %). This experiment is continued to find the optimum amount of cement added to the sludge. The result showed that by addition of 5 % cement in textile sludge can hold the heavy metal.
