When designing a volume-based runoff treatment BMP, use a calibrated, approved continuous simulation hydrologic model based on HSPF such as MGSFlood or the Washington State Department of Ecology's (Ecology's) Western Washington Hydrology Model (WWHM).
Wastewater Technology Fact Sheet Denitrification Filters
Upflow continuous-backwash filters differ in that influent wastewater flows upward through the filter, countercurrent to the movement of the sand bed. Wastewater enters the filter through the influent pipe (where methanol can be added), and then is transported downward through a supply pipe and distributors (Figure 3).
