Ceramic Polymer: Internal coating of a huge tank for brewery effluents in Laško with PROGUARD CN200

BIELEFELD, Germany - Nov. 25, 2016 - PRLog -- The large wastewater tank of a well-established brewery in Laško showed heavy corrosion damages. Extreme rust perforation occurred in its upper third; the area with fluctuating water levels. The sewage water contains an elevated oxygen level within this zone. Thus, this part of the tank is most susceptible to corrosion.

Brewery effluents have high pH values and an extensive chemical aggressiveness due to organic substances such as yeast, starch or sugar compounds. Moreover, plenty of chemical detergents are fed into the sewage of breweries.

The wastewater tank in Laško was completely and extensively renovated. For instance, only assembling the scaffold takes approximately 2 weeks. The German company ISDW used for the new coating of the tank the product system PROGUARD CN 200.
