Abstract

ABSTRACT   Food industry wastewater contains large amount of organic contaminants that cause water pollution. Approprite techniques for wastewater treatment can reduce the content of pollutants in the wastewater. Electrocoagulation is an alternative for treatment of the wastewater. This technique is pricipally a coagulation process that uses direct current through electrolysis. One of the advantages of this process is no need chemicals adding as coagulant. Electrocoagulation process has been carried out with a batch system on a scale of 1 Liter of wastewater using stainless steel electrodes with effective area of 108.9 cm2. Electrocoagulation has been performed on voltage variation of 9 to 24 Volt and operating time of 30 to 60 minutes. Samples were taken at each variable and analyzed for following parameters pH, TSS, turbidity, color, COD and phosphate concentration. The results showed that the greater voltage and operating time of electrolysis, the greater removal of contaminants in wastewater. Electrocoagulation optimal condition occurs at a voltage of 24 Volt and 60-minute operating time with efficiency TSS removal of 88.02%, turbidity removal of 76.85%, color removal of 77.49%, phospate removal of 100% and COD removal of 77.78%. Keywords: advanced wastewater treatment, electrocoagulation, food industry wastewater

Abstract

ABSTRACT   Increased production in companies will result in the increase the load of the existing wastewater treatment plant. To anticipate the future increase in the COD load, it is in need to characterize dan optimizize the existing wastewater treatment plant. Objectives of this research were characterization of operating conditions, measurement of performance as well as optimization of a food wastewater treatment plant to increase the effluent quality and minimize cost of operating cost.This study was conducted in a food industry in Jakarta. Characterization of the physical installations performed against all operation units that include the unit process physical, biological, and chemical processes. Performance evaluation was carried out using secondary and primary data covering NH4+, phosphate, nitrate, TSS, turbidity, temperature, pH, COD, MLSS, and DO. It was indentified that the biological stage was need to be optimizd especially in the nutrient addition. Almost all units there are differences between condition actual and design that lead to lower efficiencies. It was identified that the optimum nutrition added on Monday was 7 kg/day of urea, 26 kg/day of phosphate as well as 8 kg/day of nutrition liquid. The optimum nutrition added on Thursday was 32 kg/day urea, 45 kg/day phosphate and 8 kg/day nutrition liquid. By implementen these recommendations it can be expected a cost saving by 50%.   Keywords: food industry, nutrient addition, operating conditions, performance optimization
