Municipal drinking water
Drinking water as a foodstuff must meet the highest purity standards and availability requirements. This applies to the entire process chain from raw water catchment, drinking water treatment through to transport and storage.
The quality of the raw water is as diverse as the methods for its treatment. Flocculation filtration in open tanks or pressure vessels, ultra-filtration or nano-filtration, reverse osmosis, water hardening and softening, oxidation, deacidification, disinfection – the quality of the raw water and the local conditions decide which process steps are implemented. In more than 150 projects, BNA has become familiar with practically all possible treatment methods and thus has a large reservoir of technically approved control solutions.
Once treated, the water has to be transported to consumers. BNA's wealth of experience comprises all customary structures and distribution networks through to long-distance water supply systems with large pumping stations, pipe diameters of more than 1,000 mm and elevated storage tanks with a capacity of more than 10,000 m³. BNA also provides offers such as leakage detection, pipe network management, energy recovery or remote meter reading to help utilities meet quality standards and reduce costs.
