Patent ID: 8388833

Claim:
A wastewater treatment device, comprising: a tank shaped to hold wastewater to be treated, the tank being subdivided by internal walls into separate compartments, one of the compartments defining a sump cavity shaped to receive wastewater therein; at least one filtration subsystem disposed in the sump cavity and comprising: a filter pump subsystem comprising a wastewater pump operable to pump wastewater in the sump cavity; and at least one bioreacting filter fluidically connected to the wastewater pump and operable to filter wastewater received therein from the wastewater pump, the at least one bioreacting filter having: an internal fluidized-bed filter disposed in the sump cavity and supported upright by the one compartment, the internal fluidized-bed filter having: an upwardly expanding, hollow, conical filter body; filter media inside the filter body; an injector assembly having: at least one horizontal inlet; a center inlet tube; and a base at a bottom of the sump cavity configured to inject the wastewater into the filter body from the at least one horizontal inlet and the center inlet tube so as to create an upwardly spiraling flow into the filter body; and an output fluidically connected to the internal fluidized-bed filter and operable to discharge filtered wastewater out from the internal fluidized-bed filter; and a monitoring subsystem comprising monitors operable to measure wastewater process parameters of the tank selected from at least one of the group consisting of process flow, water level, water temperature, pH, nutrient concentration, total suspended solids, actual weather condition at the tank, and effects of local weather condition on the tank.
