Efficient Water and Wastewater Treatment

Application-specific solutions for the water and wastewater industry

Efficient Water and Wastewater Treatment

Reliable solutions for a more sustainable world

Water is a common good and an irreplaceable basis for life. Unfortunately, freshwater is becoming increasingly scarce due to rising consumption. Furthermore, population growth, urbanisation, and industrialisation are leading to a deterioration in water quality. For this reason, more and more complex and efficient water supply and treatment plants are needed, which include powerful and innovative technical solutions.

With extensive experience in the water sector, we support you in the planning of water treatment plants. We provide our knowledge, quality, and flexible solutions to develop highly efficient plants that meet growing demands. As experts in connectivity, signal conditioning, fieldbus solutions, remote access, data analytics, predictive maintenance, and many more, our solutions help you achieve a better world.

Your challenges - our answer:

Wastewater Treatment Plants

Constant increases in demand require adaptable plants. We have developed flexible solutions for sewage treatment plants that can be adapted quickly and economically. These include PLC or migration interfaces and our I/O systems in IP20 or IP67. In addition, there are energy consumption controls for measuring efficiency and remote access systems for facilitating maintenance. With a comprehensive view of customers, operators, owners and end users, we always find an optimal solution.

Desalination Plants

More and more often, drinking water has to be extracted from the sea or from saline lakes. The aim here is to optimise production and reduce costs. We offer products and solutions that increase the durability and efficiency of your plants, reduce energy consumption and help you to reduce damage to valves, pumps, and membranes. And thanks to modern data analysis, we can detect many damages before they occur.

Water Dam

Dams usually require large infrastructures in remote locations, often difficult to access and connected to other water facilities. All this makes it necessary to connect them to complex and often remote-control systems. Weidmüller is able to integrate these systems easily, safely, and reliably into an overall system and provide you with a suitable complete solution.
