Food and dairy

Solution

Wastewater treatment

Food production and dairies are governed by strict requirements from the authorities and therefore often have a high consumption of drinking water, as recycling is difficult and extensive in many contexts. A high water consumption results in a high volume of wastewater, which usually has to be treated before discharge.

The wastewater can be composed of several sources at the factory, e.g. process water, cleaning water and cleaning fluids, all of which may contain residual products. The load and composition vary during the day depending on production and cleaning.

Complete solution

With an AL-2 Belt Filter, wastewater can be filtered effectively or treated with the more advanced AL-2 Separation System. The choice of solution depends on the wastewater and discharge requirements, on which the necessary removal of organic matter, COD, BOD, suspended solids, fat, oil, and phosphorus can be determined. The wastewater load from this type of industry is often high, and therefore pre-treatment is necessary before discharge to the sewer. The sludge fraction from the pre-treatment process is often valuable, since it is a by-product ready for biogas plants.

Deliveries

Extensive experience

We have delivered solutions to various factories such as:

  • Processing factories for production of finished products
  • Dairies for manufacturing of dairy products, butter and cheese
  • Malt houses and breweries

Some wastewater may have a high content of dissolved organic matter and nitrogen, which cannot always be sufficiently reduced with a chemical-mechanical solution. In those cases, post-treatment through a biological plant, e.g. SBR or MBBR is necessary.

Customer-specific solutions

Wastewater from this category can cause air pollution nuisance to the surroundings if the wastewater is not treated decentralized before discharge to the sewer. The air pollution nuisances can, as an example, come from hydrogen sulfide formation, which moreover is also corrosive to many sewage systems. When the wastewater is pre-treated through an AL-2 Separation System, the amount of organic matter is significantly reduced, and therefore the risk of odor is also considerably reduced. In discharge permits, focus is also often on the pH value of the wastewater to avoid corrosive effects in the sewer. Our solutions can always be integrated with a pH regulation if it is not already part of the standard solution.
