How dense sensor fights with air pollution

The attempt of fighting with air pollution problem was carried out yet in 2013 when a professor at the University of California proposed to install air pollution sensors to high altitude weather balloons in order to measure how black carbon moves throughout the atmosphere and to accomplish air pollution control measures.

To be precise, diesel engines on trucks, locomotives, and ships, as well as from wildfires and the combustion of solid fuels for cooking and heating produce the black carbon air pollutants. It should be mentioned that the available technology used for air pollution measurement was not able to handle the changes in humidity and temperature appeared during its ascent through the atmosphere or affordable enough for mass use.

This is why the professor and his graduate students researched what it would take to develop their own air treatment device. Thus, their mobile air pollution monitoring study is made with the help of Google street view cars that allow measuring the level of air quality. The researchers carry out the analysis of how air pollution concentrations vary from block to block, including black carbon particles.

The new concept for a low-cost, solid sensor network has been developed to install additionally. The researchers install about 100 sensing systems across the area that would be examined under carbon air pollutants level over the course of 100 days. These sensors would transmit the obtained information back to the main database that would process it, monitor the changes in air pollution levels and record the sensor performance on a map.

The main idea of the concept is to measure the changes of air pollutants over time compared to traditional researches measuring black carbon and other pollutant’s variation at small space. The potential application is the measurement of air pollution at certain locations twenty-four hours a day, seven days a week, consequently, this air treatment device is able to demonstrate how traffic patterns or even the shift times of truck drivers impact the level of air pollution.

Therefore, at the present time, the best air treatment device is considered to be a wet air scrubbing system. Wet air scrubbers allow cleaning dust particles, flue gases, and vapors from a gas stream. The wet scrubbing technology includes numerous types of air treatment tools, for example, spray-tower scrubbers, packed bed scrubbers, tray tower scrubbers or foam scrubbers, centrifugal scrubbers, cyclonic spray scrubbers, and centrifugal-bubbling devices, Venturi scrubbers.

The fields of wet scrubber application vary and contain the washing dust from the air at iron mines, the removal of coal dust from the air at loading facilities, the use for an FGD process at an aluminium plant, the flushing cyanide out in a gold mining leach process, the use of wet air scrubbers for replacement and retrofitting.

If you search for the best air treatment device to improve air quality, you can buy a high-tech completely new type of wet scrubber – a Multi-Vortex wet air scrubber produced by Redwood Technology.

Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.  If you have any questions or would like to purchase a multi-vortex wet air scrubber, please contact us at
