Abstract
The study is a method of aeration treatment for raw latex wastewater produced by
manufacturing product that originated from latex processing material devices
companies in Kamunting, Taiping. Perak. Large quantities of raw latex wastewater
which high in COD and BOD value causing serious water pollution. Raw latex
wastewater is one of the industrial wastewater generated from manufacturing product
that originated from latex processing material. There are three stages of wastewater
treatment which is physical, chemical and biological treatment. In this study, only
biological treatment was performed to treat latex wastewater and the efficiency of
removal was compared between three condition aeration process. Aeration process
divided into three different conditions which is aeration of wastewater, aeration of
wastewater with bacteria and aeration of wastewater after coagulation. The hydraulic
retention time (HRT) is fixed for the aeration process is 1 hour, 2 hours, 3 hours, 4
hours, 5 hours, 6 hours and 24 hours respectively. The coagulation process used ferric
chloride as a coagulant. All the treated effluent from the aeration of wastewater,
aeration of wastewater with bacteria and aeration of wastewater after coagulation
process was compared to the standard B discharge for industrial effluent.
