Nijhuis Saur Industries completes the first full-scale ozone solution at a Dutch sewage treatment plant for micropollutants and medical residue removal
20/06/2023 Nijhuis Saur Industries B.V.,
After analyzing all treatment plants in the field of medical residues in wastewater, the Dutch sewage treatment plant (STP) at Houten emerged as a national hotspot. The state-of-the-art ozone plant is now fully operational at this STP for the additional removal and reduction of the amount of medical residues entering the environment
This is a great example of micropollutants removal, improving the water quality in the Amsterdam- Rijnkanaal and seamlessly fitting with Nijhuis Saur Industries’ purpose, called #MissionWater.
From design to solution
After successfully completing the engineering phase with Nijhuis Saur Industries’ partners - Pannekoek GWW B.V. and Witteveen+Bos - the plant was built, tested, and successfully commissioned for Hoogheemraadschap De Stichtse Rijnlanden (HDSR).
Following the successful start-up of this new application, a combined team of the HDSR Water Authority and Nijhuis Saur Industries’ experts are reviewing the results to optimize and adapt the performance of the plant.
Ozone technology partnership with De Nora
After a detailed comparison of different technologies, the HDSR Water Authority selected ozone technology as basis of design. This was not only because of its proven and effective process to break down organic micropollutants in wastewater, such as endocrine-disrupting compounds and antibiotics, but also because of its low energy consumption, limited use of scarce raw materials, and low life-cycle cost. The compact and modular installation is designed to treat a maximum of 870 m3 of wastewater per hour using a De Nora Capital Controls® ozone generator.
Another step forward to reduce the environmental impact of micropollutants
Henri Besselink, Nijhuis Saur Industries Director Projects, and Services, adds: “At Nijhuis Saur Industries, we gained extensive know-how and experience to design and build the best available solution for the removal of medical residues from municipal wastewater. The partnership with De Nora for the supply of the ozone generator technology is crucial to meet the demanding regulatory requirements, especially as the project in Houten is the first out of four projects, we are realizing for different Dutch water authorities.”
