Nitrogen And Phosphorus Remediation Of Aquatic Garden Plants In Laboratory-Scale Constructed Wetlands., Robert Polomski

All Dissertations

This research investigated the potential of growing marketable aquatic garden plants that also remediate nursery and greenhouse runoff in a subsurface-flow constructed wetland. The cost of wastewater treatment is offset by the production of revenue-generating horticultural crops. Aquatic garden plants that offer the dual benefits of nutrient remediation and aesthetic value may also be planted in bioretention basins, rain gardens, buffer zones, and filter strips.
Fifteen commercially available aquatic garden plants were grown for 8 weeks in a laboratory scale subsurface wetland in a greenhouse and received nitrogen (N) and phosphorus (P) from Hoagland's nutrient solution every two days for …
