Water Treatment
In the elimination of heavy metals from wastewater, both the use of Sulfate-reducing bacteria
and Toxicity assessment criteria use oxidation. They both oxidize the heavy metals into less
toxic compounds, and the processes are cheap and easy to apply. The two methods, Sulfate-
reducing bacteria, and Deep Sea Bacterium are biological control methods where in both cases,
live microorganisms are used in the removal of heavy metals.
Although Toxicity assessment criteria, which uses landfilling and Consortium and Biosorption
process, which uses microbes differ in their techniques of the removal of heavy metal, they both
use preventive measures. In the first one, running water containing heavy metals is treated before
it reaches water bodies. The same mechanism is applied in Consortium and Biosorption process
where microbes are used in the treatment of industrial wastes before being disposed and washed
by running water into the water bodies.
Construction of wetlands and Toxicity assessment criteria are similar as they both try to counter
the waste before reaching the water bodies, as stated in Gill, Casey, & Johnston 2017 (233). In
both cases, they aim at treating the running water as they believe it is the source of hard metals
found in the seas from chemicals and wastes collected along the way.
