Challenges

• Strict guidelines from customer for water quality concerning mineralisation and naturalness
• No use of chemicals such as chlorine or chlorine dioxide for disinfection of drinking water
• Low inherent water consumption, whereas the plant also has to provide appropriately treated water for the production site, the bottle washer, hot water station and for a steam boiler
• The permitted volume of waste water and mineral content is limited by the authority
• The raw water to be treated comes from several wells with changing quantities and an average termperature of 28°C
• Plant completely sanitiseable with hot water: chemicalfree disinfection by hot water up to 83°C
• On demand of the soft drink manufacturer: additional quality assurance with an activated carbon filter as third purification stage
• In parallel to the operation of the product water line, mineral water from a separate well can be treated with this plant - is treated with one of the three multi-layer filters
• Multi-layer filters are filled with a special filling material and backwashed with an air-watermixture - fewer backwashes are required, higher efficiency
