Abstract
A method of phosphorous reduction in stormwater runoff using iron humate, such as in the form of a filter, a layered filter bed, a stacked wall or a liner. The stormwater (fluid) runoff is sent to a fluid retention area such as a retention pond, wetland reservoir or the like where the runoff is filtered through iron humate. While the runoff is filtered, the iron humate absorbs or chemically retains the phosphorous in the runoff to produce filtered runoff with a reduced level of phosphorous. In an alternate embodiment, the runoff can be pumped from a retention pond into a iron humate filter where the runoff is filtered. In another alternate embodiment, the iron humate filter may be placed in a trench below ground to intercept and filter groundwater flows.
Claims19
A method of phosphorous reduction in stormwater runoff comprising the steps of:
- (a) channeling a fluid runoff into a fluid retention area having vegetation;
- (b) filtering the fluid runoff through iron humate to absorb phosphorous from the fluid runoff with the iron humate to create filtered fluid runoff;
- (c) during step (b), fertilizing said vegetation in said fluid retention area with said iron humate to promote vegetation growth;
- and,
- (d) discharging the filtered fluid runoff out of the fluid retention area.
A method of phosphorous reduction in stormwater runoff comprising the steps of:
- (a) lining a fluid retention area with a removable iron humate liner having iron humate;
- (b) channeling a fluid runoff into said fluid retention area having vegetation;
- (c) filtering the fluid runoff through said removable iron humate liner to absorb phosphorous from the fluid runoff with said iron humate to create filtered fluid runoff;
- (d) during step (c), fertilizing said vegetation in said fluid retention area with said iron humate to promote vegetation growth in said fluid retention area;
- (e) discharging the filtered fluid runoff out of the fluid retention area;
- (f) removing said iron humate liner when saturated with said phosphorous;
- and,
- (g) after the step (f), replacing said iron humate liner.
A method of phosphorous reduction in stormwater runoff comprising the steps of:
- (a) channeling a fluid runoff into a fluid retention area having vegetation;
- (b) filtering the fluid runoff, while in said fluid retention area, through iron humate to absorb phosphorous from the fluid runoff with the iron humate to create filtered fluid runoff;
- (c) during step (b), fertilizing said vegetation in said fluid retention area with said iron humate to promote vegetation growth;
- and,
- (d) discharging the filtered fluid runoff out of the fluid retention area.
