UASB reactor removal of BOD & COD is reasonably good, as remarked, but should be improved to up to 80%. Sludge can be reduced by drying in drying beds after dewatering to 20% DM. Since this is a food industry, total digestibility should be good enough to reach final COD < 150 mg/l with aerobic treatment, but pH correction and N & P dosing are absolutely necessary.
