Sequential flow filtration chamber for treatment of waste water and associated method

摘要

A sequential flow filtration chamber for treatment of waste water effluent from a septic tank comprises an inlet positioned in fluid communication with the septic tank for receiving waste water into the chamber, at least one partition positioned within the chamber so as to define a substantially sequential flow path for the waste water, a filter positioned within the flow path for filtering the waste water flowing therethrough, and an outlet positioned in fluid communication with the flow path for discharging filtered waste water from the chamber. The chamber may include a sequential flow path disposed substantially vertically or substantially horizontally. A sequential flow nitrification drain field for filtration treatment of waste water comprises a source of waste water, and at least one sequential flow filtration chamber. The source of waste water for the drain field is preferably a septic tank. The drain field may comprise a plurality of chambers connected in fluid communication. A method of treating waste water effluent from a septic tank includes the step of sequentially filtering the waste water effluent by channeling the waste water through a flow path containing a plurality of filtering particles so as to sufficiently treat the waste water for discharge. The step of filtering may be performed a plurality of times before the waste water is discharged.
