Wastewater is used water. It includes substances such as human waste, food scraps, oils, soaps, and chemicals. In homes, this includes water from sinks, showers, bathtubs, toilets, washing machines, and dishwashers.
Businesses and industries also contribute their share of used water that must be cleaned. Storm runoff must also be considered.
While natural processes can handle a certain amount of the contamination when this wastewater is put back into the environment, active wastewater treatment must be invoked to avoid overwhelming nature’s inherent cleaning ability.
The primary aim of wastewater treatment is to remove suspended solids, which, if left in the water tend to remove oxygen, threatening aqueous plant and animal life. Various processes are employed in modern wastewater treatment plants to clean up the effluent. However, a residual odor (largely hydrogen sulfide) often remains. Ponds and settling areas can be covered up to prevent the H2S from entering the atmosphere, but at some point, this gas has to be dealt with.
Thus, odor control scrubbers are frequently used, and the outlet of these scrubbers is monitored for their H2S concentration, to ensure that they are working properly.
For this application, Interscan supplies a suitable hydrogen sulfide continuous monitoring system, in which a coalescing filter (for the removal of water) is usually included.
