Abstract
The research attempts to study the influence operational parameters for industrial
wastewater treatment plant. Industrial production such as medical device company create
large quantities and varieties of wastewater that are causing serious environmental
pollution. Latex wastewater is one of the industrial wastewater generated from
manufacturing product that originated from latex processing material. The pH of latex
wastewater is about 3.88 and it was in acidic condition. The COD, BOD and Color of
latex wastewater were 1093mg/L, 48.8mg/L and 1751PtCO respectively. There are
several treatment processes to treat industrial wastewater and it generally divided into
three stages of treatment which is physical, chemical and biological treatment. In this
study, five selected points in the latex wastewater treatment plant was monitored and the
removal efficiencies was compared between physical, chemical and biological treatment.
Physical, chemical and biological treatment of the selected treatment plant was rubber
trap, coagulation and flocculation and biological treatment using Effective
Microorganism. The average removal efficiency of COD, BOD, Colour and TSS for
biological treatment are 79%,39%,74% and 78% respectively. Then, chemical treatment
using coagulation and flocculation method and ferric chloride as coagulant able removed
56% of COD and 28% of BOD in latex wastewater. During coagulation and flocculation
treatment processes, 53% of TSS and 38% of Colour have removed. The most efficient
treatment is biological treatment using (EM). The result also shows the studied parameter
of treated effluent follows the standard B discharge for industrial effluent.
