Process optimisation in wastewater treatment plants - wastewater flow meters, level, pH, redox and turbidity sensors

Wastewater treatment plants are places where raw sewage is treated so that it can be safely discharged into natural water bodies. This requires continuous monitoring and adjustment of various parameters such as liquid level, pH, dissolved oxygen and many others. In this article, we will take a closer look at what measurement solutions JUMO offers to effectively monitor and control wastewater treatment processes, both in industry and in municipal treatment plants.

Wastewater flow meters – precise measurement for greater efficiency

Precision flow meters are key to measuring the volume of wastewater discharged and minimising its impact on the environment and human health. They prevent wastewater emission standards being exceeded, with consequent fines and penalties.

Investing in a good quality flow meter leads to an optimised treatment process, minimising costs and reducing cycle times.
time. At JUMO, we offer a range of precision flowmeters for wastewater, including electromagnetic OPTIFLUX 2000 and ultrasonic flowmeters flowmeters from the FLOWTRANS US series, which are used to measure the flow of lightly contaminated liquids and galvanic and surface treatment wastewater.

OPTIFLUX 2000 electromagnetic flow meter

The OPTIFLUX 2000 electromagnetic flow meter can be used to measure the flow rate of water and wastewater in a variety of process applications, including pressure installations

ultrasonic flowmeter JUMO flowTRANS US W02

The ultrasonic flow meter is used for measuring slightly contaminated liquids and those with low conductivity.

Hydrostatic probe - an effective way to control wastewater levels in tanks

Controlling the level of wastewater in tanks is extremely important in the water treatment process. To ensure accurate measurements, hydrostatic probes are used. This avoids serious failures and effectively manages the treatment processes.

At JUMO, we offer a variety of hydrostatic probes to ensure accurate level measurements in tanks. One of our bestsellers is the probe for wastewater, the JUMO MAERA F27, which provides fast and accurate level measurements, even under extreme conditions and for heavily contaminated and aggressive media.

Hydrostatic probes are the optimal solution for level measurement in wastewater

PH sensors - minimising the environmental impact of wastewater

PH measurements are used in various stages of the wastewater treatment process, for example in coagulation, flocculation, settling and in biological treatment. Maintaining the pH level within the limits set by the standards is essential to ensure an efficient wastewater treatment process. A pH that is too high or too low can negatively affect the efficiency of the treatment process, which can lead to the emission of harmful substances into the environment and affect human health.

JUMO offers a wide range of pH electrodes and other measuring devices for pH control in wastewater treatment plants. The products on offer include, among others, electrodes JUMO tecLine pH electrodes, as well as transmitters and controllers such as the JUMO AQUIS 500 pH.

The pH sensors in the tecLine series can be used in heavy industry thanks to their manufacture from high-quality materials

JUMO oxygen sensor – monitoring the oxygen content in wastewater

The JUMO digiLine O-DO S10 oxygen sensor is an indispensable solution for monitoring the oxygen content in wastewater treatment processes. It allows you to effectively control the amount of oxygen supplied to the biological reactors, where microorganisms convert pollutants into safe waste. The JUMO oxygen sensor ensures high measurement accuracy and does not require frequent calibration.

The digiLine O-DO S10 optical dissolved oxygen sensor has self-diagnostic functions

Measuring turbidity in wastewater

Turbidity is one of the important water properties that has a direct impact on the quality of wastewater treatment. Proper turbidity measurements are crucial in the treatment process and prevent exceeding the standards set by legislation.

Probe JUMO turbidity probe ecoLine NTU is a high-precision instrument that is used to measure the turbidity of water in the wastewater treatment process. With it, the efficiency of the treatment process can be monitored and problems resulting from incorrect turbidity values, such as water pollution and environmental impact, can be prevented.

Redox sensor – monitoring oxidation processes

In wastewater treatment plants, redox measurements are used to control the concentration of chemical compounds such as oxygen, hydrogen sulphide and methane, which affect the quality of the treatment processes. In this way, chemical and biological processes can be adapted to changing conditions, increasing efficiency and saving costs.

JUMO offers a range of redox sensors for monitoring wastewater treatment processes, including the sensor redox sensor JUMO tecLine, which can optionally include a temperature sensor.

Water and wastewater quality data management

When it comes to monitoring important wastewater or water parameters, JUMO offers not only robust online sensor technology, but also secure data management (IIoT) in the cloud or SCADA.

Such possibilities are provided by the use of our controller PLC variTRON 300 or variTRON 500 as the core of the system. It can be interfaced with analogue sensors or our digiLINE series of digital sensors.

JUMO smartWARE Scada, JUMO smartWARE Evaluation and JUMO Cloud software. The use of these software products offers possibilities such as:

  • availability of data from any location on Earth that has Internet access to an unlimited number of users
  • individually designed dashboards, taking into account the specific features of the plant in question
  • evaluation, control and monitoring are possible via computer, tablet or mobile phone from many locations around the world

in addition to control technology tasks, our gateway to SCADA software, e.g. JUMO smartWARE SCADA or JUMO Cloud, enables manual data, e.g. from laboratory controls, to be stored and analysed in the cloud or in a SCADA database.
