Microwave real-time solids measurement

Valmet Total Solids Measurement - Valmet TS

Valmet Total Solids Measurement (Valmet TS) is a reliable and accurate microwave real time measurement used to control and optimize the solids treatment process, giving operators information on the total solids 24/7. Being the most reliable and accurate measurement for wastewater applications, Valmet TS allows savings in polymer dosing, energy, and transportation.

Industrial quality for all solids treatment applications

Measurement of solids in wastewater treatment has always been a questionable proposition. Limitations in measurement accuracy along with long-term reliability has been a concern to plant operators and engineers.  Adding to this, one of the biggest challenges is the fact that solids treatment and disposal make for over 30% of the wastewater treatment costs.

Valmet TS utilizes microwave technology to determine total organic and inorganic solids content in the range of 0-50%. With Valmet TS wastewater plants can achieve big savings with mass flow based controls, and further advance the environmental and public health benefits in the community. Controlling and developing the process can be enhanced through accurate and fast measurements, which improves the overall efficiency of a wastewater plant and provides crucial data for dewatering optimization.

Valmet TS sensors are also suitable for explosion-proof applications having ATEX, IECEx, and UKEX certifications.

  • No accumulation of solids in the clarifier
  • Energy savings in pumping

Thickening process

  • Savings with polymer dosing

Digester

  • Heating energy savings
  • More gas production
  • EX certificated (Ex II 1/3 G Ex ib nR IIC T4 Ga/Gc)

Sludge dewatering

  • Optimized polymer dosage based on massflow
  • Typically savings of 20% with optimal polymer dosing

Dry cake solids amount optimization

  • Less water in the dry cake
  • Savings in transportation and incineration costs

Twin Blade sensor

The new Twin Blade sensor model can be installed in all measurement points needed to measure solids. This sensor is suited as well for larger pipe size installations. A process temperature and pressure measurement are integrated in the sensor. The sensor is installed through a process coupling to the process pipe. The sensor has two fin shaped blades with flush-mounted antennas, and the measurement takes place between the blades.

Flow Through sensor

The body of the Flow Through sensor is a pipe that replaces an identical length of the process pipe. Flush-mounted antennas are installed on opposite sides of the sensor body so that the measurement takes place through the pipe. Sensor electronics casings are installed on the sensor body by means of a base bar, and temperature and pressure sensors are installed inside the base bar. Antenna cables are located behind a separate protective cover.

Different linings, such as non-stick lining and rubber lining, are available to suit the challenges in different kinds of applications (e.g. contamination problems, grease, fat, and abrasive material). For high pressure rating applications, Valmet TS offers a high pressure Flow Through sensor.
