What are polyelectrolyte preparation stations and what are the benefits of installing them?

Polymers supplied in bulk or emulsion form require equipment that prepares their solution with the correct parameters before being used in the wastewater treatment process.

Polyelectrolyte stations are used for this purpose. Their main task is to improve water quality by removing harmful pollutants and sludge through coagulation and flocculation processes.

Polyelectrolyte stations - benefits

The preparation and dosing of polyelectrolyte using stations brings many benefits, including improved
water quality, reducing the amount of chemicals used, as well as reducing maintenance and service
costs associated with maintenance and servicing.

Water meters in polyelectrolyte preparation plants - problems

Traditional water meters are often used in polyelectrolyte stations to measure the flow of water and chemicals. However, their use can lead to a number of problems that affect the efficiency of the station.

First of all, water meters have moving parts that are subject to wear and tear and require maintenance. Frequent maintenance and replacement of parts cause interruptions in station operation and increase maintenance costs. In addition, traditional water meters only provide measuring pulses, which means that their accuracy is limited.

In summary, the disadvantages of the water meter are:

• moving parts - more frequent maintenance and replacement of parts, higher maintenance costs
• delivery of only measuring pulses - limited accuracy

Why is an ultrasonic flow meter better than a water meter?

The ultrasonic flow meter is a better solution than the traditional water meter in polyelectrolyte stations for several reasons. Firstly, it has no moving parts that wear out and require maintenance. What's more, ultrasonic flow meters generate a continuous 4-20mA output signal, which means they measure flow in a way that is more precise and accurate than water meters that only generate pulses. Therefore, it can certainly be concluded that this is a more favourable solution for the long-term use of polyelectrolyte stations.

In summary, the advantages of ultrasonic flowmeters in polyelectrolyte preparation and dosing stations are:

• no moving parts - lower maintenance and upkeep costs
• output signal 4.-20mA, not just a pulse as in a water meter - high accuracy
• only slightly higher price

JUMO flowTRANS W01 ultrasonic flow meter

The JUMO flowTRANS w01 ultrasonic flow meter is used for flow measurement of both conductive and non-conductive media. In addition, the output signal can be provided as a current signal (4 to 20 mA) or a pulse signal (0 to 10 kHz), giving great flexibility for integration with other devices.

JUMO flowTRANS W02 ultrasonic flow meter

The JUMO flowTRANS W02 ultrasonic flow meter has all the advantages of the W01 model, in addition to a convenient process display. Furthermore, it can be integrated into a communication network via the JUMO digiLine (RS485) or IO-Link interface. In addition, the device can be configured via Bluetooth via the JUMO smartCONNECT app.

Summary

In summary, the use of ultrasonic flowmeters in polyelectrolyte stations brings many benefits, such as greater measurement precision, reliability and lower maintenance costs. Contact us for detailed information on the solutions offered by JUMO!
