Unlike other industries, the dairy industry stands at the top list in generating industrial waste. Its process reveals that processing 1 liter of milk consumes 2 liters of water. It indicates the massive scale of treating effluents to adapt operations and comply with environmental regulations. Therefore, the dairy sector opts for wastewater screens to recycle water at its best.
Effluent Treatment Plant: Major Effluents Discharged in the Dairy Industry
Let’s talk about it thoroughly! When the industry produces butter, cheese, or milk utilizing procedures like homogenization or pasteurization, it results in COD (Chemical oxygen demand) and BOD (Biochemical oxygen demand) that require to be treated before discharging into the environment. Other common effluents are milk fat, suspended solids, and odors, which dairy needs to take care of.
Most dairy production units need wastewater bar screens that effectively tackle the unbalanced levels of dissolved solids, BOD, and COD, leading to safe disposals of industrial waste.
Effluent Treatment Useful for Dairy Industry
It goes through a series of steps-
Step 1: The pH level is brought to 8.5 with pH controllers like acid or caustic. Next, any emulsions can be broken down and make solids precipitate with the help of a de-emulsifier.
Step 2: Other essential steps in the dairy effluent treatment possess Dissolved Air Flotation and flocculation. While the wastewater is streamed into a slow mix zone with flocculation, particles are assembled into larger ones to be taken and treated further by the Air flotation technique.
Step 3: A dissolved air flotation process works this way. The air flotation system bubbles get propelled from a Recycle Air Dissolving system that blows, pressurizes, and dissolves the treated effluent through the air.
Step 4: In the final step, the batch of sludge is pumped through the filter press and disposed of as per the environmental regulations.
The effluent treatment system is designed for the dairy industry, leading to compliance with environmental regulations, inadequate use of resources, and reduced operating costs.
