Water treatment for an Arla / Molvest dairy in Russia

EUROWATER has supplied and installed water treatment in many of Arla Foods Danish dairies. When Arla decided to establish a new production in the southwest of Russia together with the local dairy Molvest, EUROWATER was also the preferred partner.

To reduce the levels of iron and manganese the feed water is filtered in two parallel pressure filters. The treated water is collected in large stainless steel vessels and a pumping unit supplies it to the user points. The water is used as ingredient water for cheese production, drinking water and for cleaning purposes.

In order to prevent microbiological growth in the water a UV-disinfection unit is installed. In connection with milk separation and heat treatment, it is important that the water is free of salts to avoid malfunctions and failures of technical equipment. To this end, a softening plant with subsequent reverse osmosis system was installed in the dairy, thereby removing 98 % of the salts in the water. CIP cleaning of membrane systems in connection with whey production requires access to demineralized water of high quality. For this purpose, a compact unit was chosen comprising a reverse osmosis system with pre-treatment built on the same stainless steel frame, ready for use.
