Effect of various thickness activated carbon waste plastic shopping bags in waste reduction in industrial cleaning clothes phosphate (laundry)

Laundry industry directly in the form of phosphate throw waste into the drainage channel or body of water without prior treatment. One of the alternative technologies that can be used to overcome this problem is biosand filter and activated carbon. Activated carbon is very effective in reducing the organic materials one phosphate, wherein the activated carbon made from waste plastic bag crackle of the type of polyethylene. The general objective of this study to determine the effect of various thickness of plastic bag litter activated carbon in reducing phosphate in industrial waste washing clothes (laundry). The study design was a laboratory-scale experiment, which studied the effect of the influence of various thickness of plastic bag litter activated carbon in reducing phosphate in industrial waste washing clothes (laundry). The study design was a laboratory-scale experiments, design done in this research is completely randomized design. The population is all the waste industry washing clothes contained in Cimahi Pasantren North Road area. Statistical test results obtained p value was 0.000 (p <0.0050, so there are differences in average thickness of activated carbon waste crackle in reducing phosphate in waste water washing (laundry). The conclusions of this study there is the influence of the thickness of the active carbon garbage plastic bag in reducing phosphate in industrial waste Laundry (Laundry) with a thickness of 10 cm which can reduce waste highest phosphate.
