Waste Water: Process Control and Monitoring

The control and treatment of wastewater is vital. Wastewater contains a variety of organic substances that need to be treated and removed before the water is released back into the environment. Advanced collection systems are needed here to get wastewater to the right place at the right time and protect ecosystems. These wastewater collection systems are extremely complex and consist, among other things, of sewers for wastewater discharge, treatment plants and overflow basins. GWF offers flow measurement solutions in all areas of wastewater treatment plants around the world.
