Tailored solutions for process water
Our wastewater treatment systems are designed to cater to the specific needs of your business. For around 80 to 90 per cent of applications, our recirculation systems are the optimal choice. These systems continuously return process water to the working tank, removing solids through advanced centrifuge technology. This not only saves water and compound costs but also reduces disposal expenses. For applications where process water cannot be reused, such as when using acidic pickling or varied compounds, our flocculation systems ensure reliable purification. These systems effectively remove oils, greases, and solids, ensuring compliance with legal regulations and safe discharge into sewerage systems.
Centrifuges and flocculation systems for wastewater treatment
Walther Trowal Ltd offers state-of-the-art centrifuges and flocculation units to meet your wastewater treatment needs. They gently clean process water, effectively separating solids while retaining the compound used. Meanwhile, our flocculation systems provide a reliable solution for wastewater treatment, removing pollutants such as metals, oils, and greases. These systems ensure that purified water complies with legal standards, making disposal hassle-free. With our advanced technology, you can improve your processes, reduce costs, and contribute to environmental protection
