Water and Wastewater

Water and wastewater are fundamental aspects of urban infrastructure, encompassing both the supply of clean water to the community and the efficient, environmentally friendly treatment of wastewater. In municipal water supply, various technologies are employed to extract raw water from natural sources and then treat it to become drinking water or utility water. The entire process involves several steps: the extraction of raw water, its treatment, storage, and finally, distribution to consumers.
Precise measuring instruments are required for the monitoring and control of these processes. These include pressure measuring devices used at various stages of water extraction and distribution, as well as thermometers and level probes for temperature and level monitoring. These instruments are essential to ensure the efficiency and safety of the water supply.
In municipal wastewater treatment, similar measuring instruments are used to monitor and control a multitude of processes. This includes treatment in overflow and rainwater retention basins, aeration, sedimentation and settling basins, as well as other facilities such as screening plants, filter presses, and digestion towers. Accurate monitoring of these processes is crucial for reducing environmental impact and complying with legal regulations.
In industrial wastewater treatment, the requirements are often even more specific, driven by regulatory mandates such as the IPPC Directive, which demands the use of the best available techniques (BAT) to optimize wastewater discharge. The use of cutting-edge measuring technology in wastewater treatment plants allows industrial companies to efficiently monitor and optimize their processes, ensuring compliance with these requirements.
Application examples in both municipal and industrial water treatment include level measurement in wells, high/low reservoirs, and open waters, monitoring of filters, operation of pumping stations and pressure boosting systems, and network pressure monitoring. These applications demonstrate the diversity and crucial role of precise measuring instruments in maintaining a safe and efficient water and wastewater supply.
