Some techniques enable us to succeed in bio-remediating leachate using constructed wetlands. These techniques aim to design effective and cheap bio-remediation systems. The choice of an approach depends on the type of contaminants present in leachate. For example, using prioritization tools enables researchers to integrate toxicity data from databases with community priorities to determine contaminants that require urgent attention.
The community may choose to eliminate contaminants that cause cancer from leachate. The pollutants will disappear if people construct wetlands by planting varieties of vegetation that do well in their presence. Therefore, the designers must adjust constructed wetlands according to the pollutants they wish to eliminate. These treatment systems improve water quality by removing heavy metals, pathogens, nutrients, and other contaminants. Constructed wetlands are popular because they are easy to construct, aesthetically appealing, tolerate flow fluctuations, and are cheap to maintain. Thus, a proper selection of plant varieties during the design of constructed wetlands results in a cleaner and more beautiful environment.
