Wastewater Treatment of Wet Coffee Processing in an Anaerobic Sequencing Batch Reactor Pretreated with Electro Coagulation

Abstract

The interest for improving the quality of coffee production has led to the increased use of wet processing so as to highlight the quality and aroma of the beverage. The coffee pulping process has been causing environmental problems at the local level not only due to the consumption of water, but more due to the discharge of effluents with large volumes of organic waste. The wet processing generates enormous quantity of wastewater which causes irrepairable damage to the receiving water bodies. Indispensable. However, physico chemical treatment method coupled with biological treatment as proved effective treatment mode for safe and proper disposal of the wastewater generated. In this sense, the objective of the present study is to evaluate the efficacy of electrocoagulation batch reactor as pretreatment for anaerobic sequencing batch reactor to treat coffee processing wastewater.
