Electrochemical oxidation of sulfite ions in aqueous solutions

Gaseous pollutants that affect human health, destroy vegetation and damage materials and art treasures can be converted into harmless components by electrochemical reactions. Electrochemical gas purification methods can be applied basically in two steps. In the first step, gases to be removed are absorbed in an aqueous electrolyte. Then, in the second step, they can be converted into harmless ...

Investigation of High BOD in Final Plant Effluent

The Detroit WWTP had experienced intermittent high BOD in the dechlorinated final plant effluent from September 2003 to October 2004 and was not related to wet weather events. No NPDES violations occurred. A short-term cost effective laboratory investigation was initiated during the months that the intermittent high BOD values were occurring to determine possible causes. The results of the ...

Air pollution modelling of the Calabrian pine forests withered by the Yatagan thermal power plant, Turkey

The emissions from the chimney of the Yatagan thermal power plant have caused a 3050-hectare forest to wither. Such air pollutants as sulfur dioxide, nitrogen oxides and fly ash are carried towards the Bencikdagi Calabrian pine forests on the prevailing north-east winds. To study these effects, the Q-Basic computer program developed for the Gaussian puff model was used with meteorological data ...

Why Air Quality Specialists Should Measure for Sulfur Dioxide (SO2) in Homes & Offices - Case study

What is Sulfur Dioxide? (SO2) Sulfur Dioxide (SO2) is a highly reactive gas that is part of a larger group of sulfur oxides or SOx gases. According to the U.S. Environmental Protection Agency, the largest sources of SO2 emissions are due to “fossil fuel combustion at power plants (73%) and other industrial facilities (20%)”. Although residents in homes and offices at or near the ...

Acid Rain Progress Report

In 1990, EPA Congress established the Acid Rain Program under the Clean Air Act. The principal goal of the program is to achieve reductions of 10 million tons of sulfur dioxide (SO2) and 2 million tons of nitrogen oxides (NOx), the primary components of acid rain. These pollutants, in their various forms, lead to the acidification of lakes and streams rendering some of them incapable of ...

On-line analysis of copper foundry’s stack gas composition by low resolution ft-ir gas analyser

ABSTRACT Stack gases of a copper foundry's after-burner were measured on-site by low resolution FT-IR gas analyser. Concentrations of carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), nitric oxide (NO), nitrogen dioxide (NO2), methane (CH4) and water vapor (H2O) were continuously measured for a period of three days. Validation of the method included laboratory determination of ...

Analysis of Natural Gas Products by GC / TCD / FID

The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific ...

Treament of Hydrogen Sulfide (H2s)

This gas is often found in groundwater that contains iron and manganese. It is easily identified by its "rotten egg" odor. In addition to causing serious taste and odor problems, sulfide also promotes the growth of sulfur bacteria. Hydrogen sulfide can cause corrosion problems with iron and concrete pipes and reservoirs. Sulfides are formed by the anaerobic reduction of sulfates and organic ...
