During processing of milk and manufacturing of dairy products in the dairy industry, quite a lot of water is used. In general every kilogram of dairy product requires 2 - 4 liters of water and generates 0,5 - 20,5 liters of wastewater.
Dairy effluents contain typically quite some organic molecules, such as lactose, proteins and fat. In wastewater language we call this COD, chemical oxygen demand.
In general the aim of wastewater treatment is to remove COD, TSS, TN and TP. Concentrations of these components are important for design of a wastewater treatment - or valorization plant.
The COD of dairy effluent is very well anaerobically degradable, a good source for biogas production.
Biothane can support dairy processors to reduce costs, generate new revenue streams and achieve sustainability targets by delivering:
- Improved energy efficiency and reduced carbon emissions related to energy use by transforming wastewater into biogas and supplying back to grid or used on site for generating energy. Our Biobulk® SPAR and MemGas™ technologies are perfect solutions which can be applied for dairy wastewater treatment.
