If you are planning to run a dairy farm, you should know that the processes involved in preparing raw milk—pasteurisation, separation, sterilisation, homogenisation, etc.—will produce many by-products, such as manure, whey, corral runoffs, and other forms of liquid waste. Like waste materials produced by other industries, these by-products could also cause pollution and have negative effects on the community and the environment, which means that they should be treated and managed properly before being disposed of your farm’s premises. With that said, here are some essential methods for dairy waste management that you can adapt for your farm:
- Mechanical Treatment
Basically, this is the preliminary stage of treating dairy waste that uses a grit chamber, screens, skimming tank, and a clarifier. When using a system for dairy waste management Brisbane has, for example, you will see the grit chamber working to remove heavy inorganic matter in the wastewater, such as grits and sand, while the screens filter other large substances that can also clog the pipes while processing effluent. As for the skimming tank, it removes grease, oil, fruit peels, wood pieces, etc., while the clarifier allows waste matter at low velocity to settle down at its bottom. The collected material is known as sludge, which then requires further treatment.
- Biological Treatment
Considering that the effluent your dairy farm produces will contain organic matter, biological treatment will be a good option to take for waste management and removal. Basically, this method offers the benefits of possible adsorption of heavy metals by suitable microbes and the transformation of complex organisms into something that does not pose a serious threat to the environment. It also offers you the capability to combine various types of biological schemes for the removal of dairy waste.
- Chemical Treatment
Also known as precipitation, this method of treating dairy waste is done by adding flocculants to waste water and mixing it vigorously with agitators. When you use this as your Brisbane dairy waste management solution, you will be precipitating insoluble phosphate in the form of fine particles and then you’ll be aggregating them into larger flocks. These larger accumulations will then settle down in the pre-sedimentation basin as sludge, with the clear effluent then overflowing into another basin for further treatment.
- Sludge Treatment
Each treatment mentioned above generates a sludge that should be treated further. Typically, the sludge that you will produce from your dairy farm should be pumped into a digester, where the organic matter that it contains will be broken down under anaerobic conditions to produce gases that you can use for heating or fertilisers for your farm. As for the remaining waste products, they will be deposited in landfills.
Based on what your dairy farm requires, you can choose some or all of the waste management methods mentioned above. Bottom line is, you should employ the processes that will work for your needs, while also taking into account the benefits that they can bring to the environment.
