Sector

Food production for HORECA (Hotel, Restaurant, Cafe/Catering)

SITUATION

St. Petersburg wants to take a big step forward in environmental protection and invest around €2.3 billion by 2025. This will oblige companies to pretreat their wastewater or treat it so that it can be discharged directly into the Neva.

With the help of the modernized wastewater treatment, environmental protection is to be promoted and thus ecosystems preserved and protected.

PROBLEM

Non compliant industrial wastewater treatment system requiring an upgrade to meet strict environmental water pollution guidelines.

SOLUTION

Dissolved Air FlotationAs a leading Russian company in the field of sauces and mayonnaise production, it was a matter of course for our customer to invest in a waste water treatment plant in order to set an example for other companies.

With the ClearFox® Dissolved Air Flotation, the majority of solids and fats can be removed from the waste water at low cost and efficiently.

In order to comply with the prescribed effluent values, the wastewater is further treated biologically after flotation. The plant technology, which includes chemical and biological treatment, was installed in two 20-foot HighCube containers to save space.
