Producing dairy products such as milk, cheese, butter, and yogurt produces wastewater that contains high levels of Biochemical Oxygen Demand (BOD). This must be reduced before discharging the water to effluent treatment plants or recycling.
Key Factors Present in Dairy Waste
Water waste from these products contains sugars, fats, proteins, and sometimes the residue of additives. It can also contain pathogens from contaminated material or the production process. Hazardous or contaminated waste is occasionally contained from the gearboxes of machinery, paints, batteries, laboratory waste and lubricants and solids.
Advice and Recommendations on Dairy Wastewater Treatment
Where possible the site should be located away from sensitive environments. Improving the management of waste will lower the cost of purchasing materials, and also reduce the impact on the environment.
Dairy wastewater treatment involves treating the waste water for use in irrigation. It is advisable to implement a plan for water collection and recycling for both rain and grey water.
Check if dairy wastewater treatment sludge can be composted at an approved off-site factory.
Dairy does not create toxic effluent. Odor control must be in place in dairies, and a monitoring program for both odor control and wastewater treatment must be in practice.
Dairy Processing Effluent Treatment
Technology must be usedto separate waste water from dairy processing effluent. This will reduce the volume of the waste water. Uncontaminated storm water can also be separated from the waste and beeither reused, collected, or recycled.
If stormwater is to be used in the operation of the plant it does not need to be separated. Contaminated waste watermust be sent to a plant.
Dairy wastewater treatment isdone by use of equipment and separation methods including dissolved air flotation, centrifugation and micro-filtration. This effluent treatment reduces the rate of sludge build up in lagoons and the wear on dairy equipment pumps. It quickly reduces the BOD concentration in effluent before disposal.
Always consider the environment and health and safety when re-using waste water.
Efficient waste management is an important component of dairy processing operations. With the proper equipment dairy wastewater treatment can be quickly and easilymanaged. Contact us for further information.
