Water and wastewater – IPTech – IoT | Vehicle Tracking | Security

Water and wastewater management

Drinking water is a valuable foodstuff. Wastewater treatment is just as important a task as the monitoring of drinking water supplies.
IPTech supplies sensor technology for level, switching and pressure – perfectly adapted to the requirements of the water and wastewater industry.

Wastewater treatment

Sewage treatment plants around the world rely on IPTech measurement technology because they place great importance on high plant availability, maintenance-free operation and accurate measurement data, as the basis for automatic control of the various process stages.

Application

Accurate monitoring of the river level is an important prerequisite to be able to react quickly and correctly in the event of a flood. Data recording and transmission via radio link is the optimal solution for getting level information on rivers in remote areas without power.

When new building zones are opened up, it is often quite expensive to build a sewerage network with the necessary downward slope. In such cases, a vacuum sewerage network offers an interesting alternative to traditional sewer systems. The wastewater is transported to the pumping station under vacuum, which allows significantly smaller pipes to be used and stretches of upward slope spanned. A central vacuum pumping unit conveys the wastewater from households via a central sewage discharge into the public sewer system. To effectively control the system the level in the vacuum tank must be continuously monitored.

Application

In the central drinking water supply system, air-bladder chambers are used to compensate for pressure fluctuations in the supply line. They are used primarily to stabilize smaller water networks, where, for economic reasons, a water tower is not an option. A pressure transmitter is deployed to monitor the tank and control the pumps. A low level switch detects the minimum water level in the tank and thus prevents air from entering the water supply network.

Application

Spring water originates from surface water, which passes down through layers of porous rock on its way down into the earth. It then flows horizontally along a layer of clay or rock and thus forms a spring. To obtain drinking water, the spring is impounded in some type of structure and protected against contamination. The spring water flows into a settling pond and then into a reservoir. A reliable level measurement is critical in ensuring a sufficient supply of drinking water.

Special challenges:

Environmental influences from rain, wind and sun

Application

To filter suspended matter out of the water, precipitants are added to the water. When small air bubbles are injected into the liquid, suspended matter is bound to the rising bubbles and drawn off at the water surface. In order to achieve the best possible bubble formation, the pressure in the air supply is regulated to stay within narrow limits. Reliable and accurate level measurement is necessary to achieve efficient removal of the suspended matter.

Application

During seawater desalination, substances often have to be removed or separated from each other. One method for separation or precipitation is filtration. Superior product quality results only when the filter functions properly. For that reason it must be ensured at all times that the filter is performing adequately. This requires continuous monitoring of the filter.
