Constructed wetlands have been used for several decades in the United States and Europe to remove nitrogen and other traditional pollutants from wastewater. Coates is just one of many scientists across the globe who are working to harness the ability of various bacteria to remove harmful pollutants from water. Some plants are able to extract and concentrate particular elements from the environment, thereby offering a permanent means of remediation. ADVERTISEMENTS: Some of the advanced treatment techniques to remove pollutants from wastewater are as follows: 1. . In antiquity, “crazy as a painter” was a phrase borne from the demented behavior of lead-poisoned painters. Chromium is usually found in water systems in two main states: Cr(III) and Cr(VI). Well, here is the first problem: Not all water filters work well for all radiological pollutants. For more information about any of the steps of the water treatment process, see the Chlorination fact sheet. Root Zone Treatment 4.
