    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.

    摘要： The filter comprises a pressure vessel, which contains vertically spaced apart partitions for supporting respective layers of a particulate filtering material. In order to ensure that the result of the filtration will not be influenced by fluctuations of the flow, pressure and temperature conditions of the solids-laden fluid to be filtered, each layer of filtering material is enclosed by a sheath, which is permeable to the fluid to be filtered and impermeable to the filtering material and which together with said filtering material constitutes a filtering package, which is engaged at its top and bottom by two of said partitions and is compressed by said partitions under constant pressure. The partitions engaging each of said filtering packages at its top and bottom define with said filtering package passages for the supply of said solids-laden fluid to said filtering package and for withdrawing filtrate from said package.
