Inherent Water Management Conserves Resources

Motivated by Guiding Principles of Sustainable Production

Brewery Schwäbisch Hall

Task

ATN Water Treatment was commissioned by Löwenbrauerei Hall to complete a feasibility study for treating mineral water to produce brew water. The company decided to analyse its material and energy flows when it notices excess use of inherent water. It is also committed to more sustainable production and preventive environmental protection. Wildbadquelle Mineralbrunnen GmbH & Co. KG – which manages own wells – has been part of the company since 1968. For quality- and mineralisation reasons, the wells had to be operated continuously even though not all water was used to produce of mineral water and sweet beverages.

Targets/Challenges

The most self- sufficient water supply possible should be achieved through the volume profile of well yield and excess water from it
Creation of two water types with different mineralisation (brewing water, process water)
No use of added chemicals for ecological reasons
Waste water sakinity to be avoided
No addition of sulphateto adjust brewing water quality
Integration of an energy management system encompassing all pumps to increase efficiency in production

The main issues covered in the feasibility study were

Data acquisition on all water streams within the production processes

Description of water tanks and water network

Excess water after treatment adequate for the facility’s supply

Possibility of economical treatment of mineral water with > 80°dH to be processed into brewing water
