Many regions around the world are facing water scarcity, and industrial processes are contributing to the problem. The demand for water in manufacturing is expected to increase by 400% by 2050 [OECD], as many industries are water intensive. Water plays directly or indirectly an important role as a solvent, cooling liquid, wash and clean liquid and many other applications.
In response to water scarcity and rising clean-water and wastewater discharge costs, industrial facilities are moving towards water reuse all over the world. Water reuse is when the wastewater for the entire plant or specific process is treated to a quality that makes it possible to feed it back into the facility’s water cycle. Water reuse for temperature control in cooling towers is a sensible place to start because cooling towers consume large amounts of water across the industry, require a relatively low quality of water and thereby water reuse can be put into play with a lower capital investment than water treatment for core processes.
Grundfos is able to deliver solutions for all key phases of water treatment, including biological, chemical and physical treatment. This will make your water reuse system state-of-the-art when it comes to reliability and cost-efficiency, and at the same time make it future-ready for increasing water reuse demands.
We reuse 80% of our rinsing process water
At Grundfos, we have our own water-saving ambitions. We want to cut water consumption by 50% by 2025 compared to 2008. In our wastewater treatment plant which opened in 2018, we use Grundfos iSOLUTIONS water reuse technology. The solution helps us reuse around 80% of the wastewater from our rinsing process and the facility saves around 5,000 m3 of water a year.
