Task
At its site in Weißbach near Heilbronn, Konrad Hornschuch AG manufactures films, high-tech synthetics, and imitation leather for a variety of applications. From here, international customers in more than 100 countries around the world are supplied.
The goal was and is to prevent corrosion and biofouling in the systems in the long term while reducing water consumption through optimized bleed management.
Other important requirements included compliance with the equipment manufacturers' specifications and easy handling of the operating materials on site.
System specifications
- Type of cooling: Evaporative cooling system and various semi-open cooling circuits
- Materials in the system: steel, galvanized steel, copper, stainless steel
- Circulation volume: 5–20 m³
- Make-up water: River water, fully desalinated
Solution
Solution
ALMAWATECH developed a coordinated operating resource concept based on a multifunctional protection strategy consisting of:
- Corrosion protection for mixed metal materials (ALMA Treat KK 1000; ALMA Treat VKA 1000)
- Biocide management against microbiological growth (ALMA BIO 400)
The corrosion protection for the operating equipment is dosed fully automatically depending on the make-up water volume, and the biocide dosing is time-controlled for the corresponding cooling circuits, ensuring stable operation with minimal use of chemicals. In addition, quarterly water analysis and system checks are carried out by ALMAWATECH Service.
