Ozone Chamber demonstrated breaking down rubber products

We just finished a quick video on the use of our CH-3 Ozone Chamber in use.  A few latex gloves and rubber bands were exposed to ozone in this video for a demonstration.

Ozone set-point of 800 ppm was used.  Watch how quick we achieve 800 ppm and how well we maintain 800 ppm toward the end of the video.   Should you have a need for an ozone exposure chamber, or any ozone testing services, let us know.  We would be glad to find a solution that fits your needs.

Top-quality drinking water through ozone treatment

It can be argued that drinking water is the most important sustenance that humans need. Its preparation requires complex processes. To oxidize and disinfect drinking water in the course of treatment, ozone is often mixed in. Because of its high reactivity, ozone must be produced and added on-site under strict safety regulations. With that in mind, VEGA’s pressure transducers make an important contribution to the continuous processing of top-quality drinking water.

The water supply system in Baden-Württemberg is one of the largest and most traditionally far-reaching water supplies in Germany. Around 250 cities and municipalities are supplied with about 90 million cubic meters of drinking water every year. The quality of water, and a high level of security of supply take center stage in the regional water supply’s management.

At the beginning of the 20th century, the population in the central Neckar region was already growing rapidly as industrialization progressed. An extraordinarily far-sighted plan at the time was to bring drinking water from the Danube Valley at the city of Ulm in the Remstal region, to Stuttgart. This laid the foundation for the regional water supply system. Plant for the conversion of river water to drinking water consists of a raw water pump, which draws the water directly from the river, a pressure pipe from the pumping station to the waterworks, and the treatment facilities in the waterworks.

In peak times, up to 2,300 liters of river water per second can be converted into drinking water. The injection of highly active oxygen (ozone) for oxidation and disinfection during drinking water treatment represents state-of-the-art technology. Ozone oxidizes dissolved and particulate organic matter and kills or inactivates existing microorganisms. Ozone is always formed when some type of energy decomposes molecular oxygen into individual oxygen atoms, which then react with molecular oxygen to form ozone. This can occur through UV radiation, lightning strikes and also high-voltage electrical discharges.

Because of its high reactivity, ozone is produced, transported and added to the water on the spot and in compliance with strict safety regulations. The actual production process takes place in pressurized reactors, where electrical energy is applied to convert oxygen into ozone. Then, the resulting gas mixture flows into an ozone collecting pipe. The maximum ozone concentration is about 180 g/Nm³ at an operating pressure of 1.3 bar. Injectors feed the ozone into the water, while mixers distribute the tiny ozone bubbles evenly throughout the water volume. For a few minutes, the water remains in large containers during which time oxidation and disinfection take place.

To ensure that pressure measurement in the ozone collection pipe and at other important measuring points is safe and reliable, the engineering department decided to use VEGAbar 82, the pressure transmitter with ceramic Certec measuring cell and a second line of defense. This is an additional process separation by means of a gas-tight feedthrough above the process connection. Although the measuring cell is permanently resistant to ozone, the second line of defense provides an extra layer of protection against the leakage of ozone from the pipeline through the pressure transmitter.

VEGAbar 82, therefore, plays an important role in safe ozone generation, as well as in the continuous production of top-quality drinking water.
