Industry Spotlight – Wastewater treatment!

Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused. This process is conducted in order to transform raw sewage into water clean enough to be discharged into a lake or stream without causing harmful environmental or ecological consequences.

Wastewater treatment generally involves 3 stages of treatment: primary, secondary and tertiary treatment. – Primary treatment consists of temporarily holding the sewage in a basin or clarifier where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface.

Issues

During the operation of wastewater treatment, harmful gases are emitted from the process, these include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrogen sulphide (H2S), chlorine (CL2), ozone (O3), sulphur dioxide (SO2) as well as this, oxygen depletion is something that needs to be taken into consideration.

The above-mentioned gases can be harmful for many different reasons, to workers exposed to them. Some of the gases mentioned, for example Hydrogen Sulphide is a dense, colourless, odourless toxic gas that corrodes infrastructures and impairs the performance of wastewater treatment operations. Due to its odourless quality, it makes it impossible to know whether it is present or not, which in turn leaves workers exposed to high risk of nausea and irritation.
