heal.abstract	In this study, a new method for the treatment of currant-finishing wastewater was proposed in the context of the 11 clean technology (TM) concept. This method consisted of two stages, In the first stage, the currant-finishing wastewater was recirculated in the currant-wash process and in the second stage this wastewater was utilized for the production of energy through anaerobic digestion. Recycling ratios from 0 to 95% were examined. By increasing the recycling ratio, effluent's COD increased from 3808 to 43,722 mg/l, effluent's BOD from 681 to 5378 mg/l, total sugars from 2.57 to 42.13 g/l, total phosphorous from 0.79 to 5.14 mg/l and total Kjeldahl nitrogen from 7.36 to 51.9 mg/l while fresh water addition decreased from 6 to 0.3 kg per kg of currants processed. The optimum recycling ratio range for the wastewater energy utilization proved to be 30-40%. In this range, the mass of COD and sugars digested was maximized resulting in the highest biogas production. Thus, the proposed system could be promising since water consumption is minimized and wastewater energy utilization is achieved rendering the process almost energetically self-sufficient.
