Dairy products

Solutions adapted to the dairy sector with clear advantages and benefits

The dairy industry is dedicated to the production of milk and the manufacture of processed by-products such as yoghurt, cheese, butter and cream, among others. This sector generates a lot of process water highly charged with organic materials, nitrogen and phosphorus, detergents, acidity, oils and fats.

Wastewater is generated by:

Production process;
Cleaning operations on tanks, equipment and installations, surfaces (floors, walls), leaks and spillages;
Periodic pouring operations. These operations represent the largest consumption of water, used to maintain the required hygiene and quality conditions;
Sanitary uses.

Sizing on a case-by-case basis;
Proven experience;
Reliable and lasting compliance with legal requirements;
Elimination of soil and groundwater contamination due to the complete watertightness of the treatment units;
Ease and speed of installation (pre-assembled components and ISO 9001 factory conditions);
Easy to upgrade if production capacity increases - modular solutions.

For this industry, ECODEPUR® adopts a case-by-case sizing of integrated treatment systems, taking into account the particularities of each facility, namely production capacity, type of products manufactured, availability of land and discharge requirements (collector/natural receiving environment/reuse).

The treatment scheme basically consists of the following unit operations:

Pumping upstream of the treatment system;
Preliminary treatment, with fine sieving to remove coarse and fine solids (< 2 mm);
Equalisation / Homogenisation, to minimise the effects of the great variation in the flow and quality of the effluent, optimising the operation of the downstream treatment stages;
Dissolved air flotation (DAF), in order to remove suspended solids, grease and organic matter. The performance achieved by DAFs can be optimised with the addition of coagulants and flocculants;
Biological treatment. In this context, ECODEPUR® has a wide range of technologies available, including activated sludge reactors with a nitrification/denitrification process in the SBR regime and MBBR mixed bed reactors;
Tertiary treatment, whenever the treated effluent is to be reused or in situations of more demanding discharge standards.
