Methods, systems and compositions for a green
sorption media for
bioretention soil amendments in drainfields for on-site waste water systems filled with the green
sorption media to foster an anaerobic or anoxic environment saturated. The green
sorption media includes one or more recycled materials, including tire crumb,
sawdust, orange peel, coconut husks, leaf
compost,
oyster shell,
soy bean hulls and one or more naturally occurring materials including
peat, sands, zeolites, and clay. The
wastewater filtration system for a passive drainfield includes the green sorption material mixture, a
cell including baffled compartments and a riser, the
cell filled with green sorption material mixture to provide an alternating cycle of aerobic and anoxic environments, an influent
distribution system to distribute the influent over the
cell, and a
piping system arranged for dosing the cell to sustain the functionality of the green sorption material mixture to remove
nutrient content in
wastewater.
