Preliminary Study Of Water Quality Surrounding The Petrochemical Plants At Teluk Kalong Industrial Area

Wastewater from industry could lead to water pollution if not properly treated. This research aims to analyze quality of effluent discharge surrounding the petrochemical plants at Teluk Kalong Industrial Area. The purpose is to identify of uncertain level of Biochemical Oxygen Demand (BOD), Total suspended Solids (TSS), heavy metal zinc and copper. These properties could affect water quality if the effluent is not properly treated prior to discharge on water surface. In order to obtain the aim of this research, the laboratory analysis has been carried out on the waste water discharged from the petrochemical industry area. An experiment was conducted and discovered that the minimum value for BOD, TSS, Zn and Cu was 35.55mg/l, 21.667mg/l, 0.006mg/l, and 0.001mg/l accordingly. The maximum value for BOD, TSS, Zn and Cu was 60.150mg/l, 742.667mg/l, 0.839mg/l and 0.044mg/l accordingly. As not all parameters obtained satisfactory to the local standard, it is recommended further research be performed to ensure appropriate result complying to the regulatory standards.
