ABSTRACT:
A fluid separation and delivery apparatus and method are provided for filtering a fluid from a source and delivering a filtrate derived therefrom to a first destination, and delivering a decantate derived therefrom to a second destination. The fluid separation and delivery apparatus for the method comprises a filter device having an inlet port for connecting to a fluid source, a first outlet port for directing filtrate to a first destination, and a second outlet port for directing decantate to a second destination; an inlet pump connected between the inlet port of the filter device and the fluid source for pumping fluid at a flow rate of Qininto the filter device; and an outlet pump connected between the second outlet port of the filter device and the second destination for pumping fluid at a flow rate of Qoutout of the filter device to the second destination. The outlet pump and the inlet pump are sized and controlled so that Qoutis less than Qin, and so that the resulting flow rate of filtrate Qrfrom the filter device through the first outlet port to the first destination is equal to Qin−Qout.
