Effect of Alternative Nutrient Sources During Anaerobic Degradation of Potato Wastewater

The supplementation of nutrients on biological wastewater treatment in many cases may become a relevant part of the treatment cost. In that sense, the finding of new efficient and economic nutrient sources is very important in large scale industrial applications. This work reports on the effect of four readily available alternative nutrient sources during anaerobic degradation of potato wastewater: Peptone, soybean meal, sludge from an aerobic wastewater treatment plant (aerobic sludge) and NH 4 NO 3 plus Micronutrient Supplementation (MS). The addition of alternative nutrient sources changed the rate limiting step from the last steps to hydrolysis in all the cases. While the added soybean meal allowed obtaining the higher final conversion, the degradation rate was slower than the non-supplemented control. The assays with NH4NO3+MS as nitrogen source presented the highest degradation rate. Moreover both NH4NO3 and MS are needed to improve the degradation rates. The percentage of residual COD after treatment was similar for peptone, aerobic sludge and NH4NO3+MS test. However, the lowest percentage of residual soluble COD was obtained when the aerobic sludge was used as supplement. The aerobic sludge presented Co and Mo deficiencies. Finally, taking into account the advantages and disadvantages discussed, among those tested, the aerobic sludge seems to be the best alternative nutrient source for industrial applications.
