In the dairy sector, it is important
to focus on the
purification of wastewater from
discharges deriving from the washing of equipment used
in the processing of milk and cheese production
(polyvalent, double bottled, formers, pasteurizers,
etc.), packaging and bottling lines, storage tanks and
means of transport of milk and finished products.
Most of the dairy wastewater also
comes from washing floors, production departments,
workbenches, heat treatment plants and more.
Dairy wastewater is completely free
of toxic agents, but due to its high organic content
(whey, fats, production residues, etc.), it cannot be
discharged directly into water bodies or municipal
sewage networks.
To ensure compliance with the parameters imposed by
current legislation (Legislative Decree 152 of 2006),
wastewater from the
dairy industry (cheese factories,
yoghurt bars, dairies) must be treated in special
purification plants.
