Wastewater from
the dairy industry

Gli effluenti prodotti dall’industria lattiero/casearia, che più frequentemente si originano con il ciclo produttivo, sono caratterizzati principalmente dai seguenti tipi di refluo:
water from washing the vats in which milk is coagulated
liquid from draining the curd, the quantitative and qualitative properties of which vary according to the type of cheese produced
washing the tanks of transport vehicles
used brine from the salting rooms
water used for washing milk-processing spaces
water from washing the equipment employed

It follows that the pollutants contained in dairy wastewater are the residues of milk and its by-products.

The residues from products used to clean rooms and equipment, such as alkaline or acid solutions or detergents with surfactants, can also be added to this. Although free of particular toxic agents, this water must be treated before it can be discharged into sewers or surface waters.

The quality of the effluent produced.

In generale può essere stimata a partire dal numero di capi abbattuti oppure dalla quantità di prodotto trasformato.

Therefore, the chemical/physical and microbiological properties of the wastewater are extremely variable. In addition, the discharge contains pollutants from the products used in the washing and disinfection of rooms. This is why biological treatment is chosen on the basis of the type of processing done by the client. We have collaborated on the construction of wastewater treatment plants for:

milk packaging



production of butter, dairy products and yoghurt

COMS Srl collaborated in the construction of the purification plants of the companies mentioned.
