Distillieries - Environmental Clearance

Best Practices & Latest Technologies available and referenceBest Available Technologies across entire process: Apply Clean-in-place (CIP) methods for decontaminating equipment. Use high-pressure, low-volume hoses for equipment cleaning. Use re-circulating systems on cooling water circuits.Filtrate bottom sediments from final fermentation tanks for use as animal feedBest Available Technologies for effluent treatment:Wherever possible, waste water segregation is recommended. There exists potential for highvolumelow-strength streams to be either:-recycled (following suitable treatment)-discharged directly to sewer (without treatment)-mixed with treated final effluent prior to dischargeThe options available will be dependent upon the receiving water and hence the consent todischarge. By segregating low-strength streams, a treatment facility can be reduced in size bydesigning on high strength waste waters released from an installation. Fermentable and nonfermentablewastes are kept separate to maximize potential for re-use.In general, when applying techniques for the treatment of waste waters released from the brewerysub-sector, the following unit processes may be considered: Screening. Primary treatment. With regard to the pollution strength, aerobic or anaerobic biological techniques are regardedas BATBest Available Technology for Waste Water Treatment:Treatment for discharge to sewerThe level of treatment required prior to discharge to sewer is dependent upon the consent todischarge conditions. An economic balance needs to be achieved taking into account tradeeffluent charges and the capital and operating costs of a new effluent treatment plant.
