Ozone Concentration and Dosage Equations

20 gpm x l/gal x 60 min/hr. x 2 ppm = 9084 mg/hr. ( gm/hr.) Remember that 9 mg/hr. will permit you to dose the water with 2 ppm of ozone. This does not mean that 2 ppm will be your final dissolved ozone concentration. Due to efficiency losses with injecting ozone and ozone demand of the water, your dissolved ozone concentration will be less.

How is ozone measured in the atmosphere?

on research aircraft to detect ozone over a distance of many kilometers along the laser light path. A network of ground-based detectors measures ozone by detecting small changes in the amount of the Sun’s UV radiation that reaches Earth’s surface. Other instruments measure ozone using its absorption of infrared or visible radiation or its emission of microwave or infrared radiation at ...

Dobson | Network for the Detection of Atmospheric ...

A global network of Dobson instruments was established during the years following the first International Geophysical Year in 1957. A modern instrument, the Brewer Ozone Spectrophotometer, was developed in the nineteen seventies and introduced into the global network in 1982 with the delivery of instruments to Greece, Sweden, Germany and Canada.

Ozone - Wikipedia

Most people can detect about μmol/mol of ozone in air where it has a very specific sharp odour somewhat resembling chlorine bleach. Exposure of to 1 μmol/mol produces headaches, burning eyes and irritation to the respiratory passages.

NASA - Discovering the Ozone Hole: Q&A With Pawan Bhartia

Ozone was a hot topic among scientists an August 1985 meeting in Salzburg, Austria, a few days after Pawan Bhartia presented the first satellite image of the ozone hole. In attendance were Donald Heath, who initiated the ozone measurement program at Goddard in the late 1960s, and the late Sherry Rowland, who later received the Noble Prize for ozone layer research.

Determination of ozone

The calibration system is shown in Figure Various ozone concentrations (in air) are generated and accurately measured with the primary UV calibration photometer. These ozone calibration concentrations are simultaneously sampled by the ambient ozone analyzer to be calibrated via a common manifold. The analyzers response is plotted against the ozone concentrations measured by the primary UV …

ACP - An evaluation of the ability of the Ozone Monitoring ...

Abstract. Nadir-viewing satellite observations of tropospheric ozone in the UV have been shown to have some sensitivity to boundary layer ozone pollution episodes, but so far they have not yet been compared to surface ozone observations collected by large-scale monitoring networks. Here we use 2013–2017 surface ozone data from China's new Ministry of Ecology and Environment (MEE) network of ...
