Study
- Citation
- Sansalone, J., Liu, B., & Ying, G. (2010). Volumetric Filtration of Rainfall Runoff. II: Event-Based and Interevent Nutrient Fate. Journal of Environmental Engineering.
- Study description
- This study examined phosphorus treatment through the use of a volumetric clarifying filter (VCF). The study assessed the VCF through time without maintenance and assessed the differences between phosphorus mass in influent and effluent and the partition between dissolved and particulate phases.
Response
- Cause term/trajectory
-
Habitat (physical alteration)
- Cause description
- Volumetric Clarifying Filter (VCF)
- Effect term/trajectory
-
Water quality - nutrients (phosphorus)
(Decrease)
- Effect description
- Phosphorus fraction. All phosphorus fractions (settleable, sediment, dissolved) and thus total phosphorus were significantly reduced from influent to effluent from the VCF.
- Response measure type
- Other
- Statistical significance
- The median of each frequency distribution for P phases was significant (p<0.05)
- Response measure description
- Lognormal frequency distribution
