What are Wastewater Contaminant issues faced by Dairy industries?
High demand of milk produces more wastewater.
Because of the high demand for milk and milk product, dairy businesses have risen in most countries. Dairy industry have grown as a result of this rise.
Major pollutants present in DAIRY wastewater
The wastewaters discharged from this industry contains high concentrations of nutrients, chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS) and organic and inorganic contents. These can cause serious and long term environmental problems, if not properly treated.
Many dairy wastewater treatment plants have low F/M ratios on off-days, which causes sludge thickening and poor BPR performance. Most dairies don't have an equalization tank, or if they have, it's too small to handle the flow and organic loading fluctuations.
The conventional bio treatment methods are most suitable for dairy wastewaters due to the high biodegradability!
Long chain fatty acids generated during lipid hydrolysis, on the other hand, have an inhibiting effect during anaerobic treatment. For the biological treatment of dairy wastewaters, sequencing batch reactor (SBR) and up flow anaerobic sludge blanket (UASB) systems appear to be the most promising technologies and can be provided by one of India’s major wastewater treatment technology manufacturers, Netsol Water.
Varying nature of wastewater in Dairy Industry
Because each milk product requires its own technological line, large changes in effluent quality and quantity are a major issue in dairy operations.
1: With the commencement of a new cycle in the manufacturing process, the composition of dairy effluent changes, impeding the work of in-factory wastewater treatment plants. Furthermore, time-dependent intense effluent volumetric changes are prevalent.
2: Washing the equipment and flooring as the final step in every process cycle results in daily and hourly modifications.
3: Seasonal differences are due to a larger dairy plant load in the summer compared to the winter.
4: Hourly homogeneity can be explained using coefficients in the 1.4–2.0 range.
5: The diurnal inequality coefficient varies depending on the seasonal nature of dairy processing, ranging from 1.5 in summer to 2.6 in winter, as per one study.
6: The actual concentration of polluting dairy effluents varies greatly depending on the profile and capacity, production technique, the type of equipment used, wastewater reuse, raw material loss, waste management, and so on.
7: The rapid discharges created in the cleaning of tank trucks, pipes, or equipment at the end of each cycle are a crucial component in the volumetric loading of dairy wastewater treatment plants. The effluent volumes are larger than those of produced milk in such circumstances. On average, wastewater discharge accounts for 70% of the fresh water consumed.
Reusing of wastewater in Dairy Industry
The most pressing problem is figuring out how to reuse water and manage wastewater in a cost-effective and environmentally sustainable way. Alternative treatment technologies, like as coagulation, adsorption, RO and electrolysis processes, are being studied as alternatives to biological treatment approaches.
