PCT No. PCT/AU84/00098 Sec. 371 Date Jan. 28, 1985 Sec. 102(e) Date Jan. 28, 1985 PCT Filed Jun. 1, 1984 PCT Pub. No. WO84/04703 PCT Pub. Date Dec. 6, 1984.Liquid separating device apparatus particularly for separating oil and water components from a mixture thereof. The apparatus includes a tank (50) for the liquid and two banks (62, 64) of cyclone separators for separating oil and water from the liquid in the tank. A control circuit (102) receives input from height sensors (180, 182, 184, 186) sensitive to the height of liquid in the tank (50). Circuit (102) is responsive to the sensed liquid height to vary the flow rate of liquid through the apparatus by varying the rate of operation of a pump (60) which pumps liquid from the tank (50) to the banks (62, 64), by controlling a valve (66) to direct the liquid either to one or to both the banks (62, 64) and to constrick flow from the banks (62, 64) by varying the resistance to flow through variable chokes (68, 70) which receive outflow from the banks. |
