The dairy business is one of the greatest polluting food industries because of its high water demand. One of the main causes of water contamination is dairy. India’s dairy sector is predicted to grow quickly due to the country’s rising milk demand, & waste production along with environmental concerns will only become more significant. Poorly treated effluent with a substantial amount of contaminants resulting from subpar design, execution, or treatment systems poses serious environmental issues when it is released onto surface land or water. Therefore, even an effluent treatment plant necessary for the dairy industry, which is only possible if companies such as Commercial RO Plant come in action in such dairy sectors.
Waste Water effluents from the dairy sector:
Highly organic materials found in dairy waste water are prone to decomposition. This calls for immediate & sufficient treatment of waste water before to release into the environment. Dairy waste contains nearly all organic materials that decompose naturally. Consequently, the wastewater can undergo either aerobic or anaerobic biological treatment. These wastes, which are usually discharged as solids, liquid effluents, along with slurries comprising a range of inorganic along with organic compounds, are regarded as possible pollutants when they negatively affect the environment.
Control of effluent through ETP:
Meeting discharge regulations in the dairy industry has long been a significant concern for business people. Each industry’s effluent treatment plant is required to treat wastewater for this purpose inside their own industry. Industries must adhere to the effluent discharge guidelines before releasing treated wastewater onto land or into any body of surface water. Proper procedures in the ETP need waste water characterization, treatability studies, & the planning of appropriate units along with procedures for effluent treatment specially designed & manufactured by companies like Commercial RO Plant.
Significant degrees of BOD (biochemical oxygen demand) alongside COD (chemical oxygen demand) estimated in mg/L are formed during the industry’s treatments through pasteurization when producing milk, processed butter, or cheese; these materials must be handled before being released into the environment. Dairy product odors, milk fat, as well as suspended particles are additional frequent effluents that need to be treated.
A dairy wastewater treatment plant is necessary for every dairy production facility in order to safely dispose of industrial waste by effectively addressing imbalanced levels of BOD, COD, particles in suspension, & dissolved solids.
Dairy industry operations involving Effluent treatment
The steps that the dairy wastewater treatment facility takes are as follows:
1) First, the pH is brought down to 8.5 with the application of pH controllers such acid or caustic. A de-emulsifier is next employed to break down any emulsions & cause the solids to precipitate.
2) The processes of flocculation & dissolved air flotation are also important in the sterilization of dairy wastewater. The effluent wastewater is flocculated by running it over a slow mix zone, which collects the particles while making them larger. The air flotation technique is then used to treat the wastewater further.
3) By blowing the treated effluent, pressurizing it, & subsequently dissolving it with air, a Recycling through Air Dissolving system propels the air flotation system bubbles. This is how the dispersed air flotation technology operates.
4) In compliance with environmental standards, the sludge batch is subsequently run through the filter press & disposed of.
Finally, an Effluent Treatment plant necessary for the dairy industry designed specifically for the best leads to reduced operational costs, smooth dairy operations, resource efficiency, environmental compliance, & peace of mind.
Conclusion
The dairy business is the one that produces the most industrial waste, in contrast to many other industries. According to the dairy industry, processing one liter of milk requires about two (02) liters of water. This demonstrates unequivocally the enormous volume of effluents that need to be processed in order to enhance operations & adhere to environmental standards which eventually makes an effluent treatment plant necessary for the dairy industry.
Commercial RO Plant is the top producer of water plus wastewater treatment systems in India. The idea of commissioning sewage treatment plants & effluent treatment plants for various industries is one of our environmental services.
