Abstract
Apparatus for measuring the turbidity of water, which apparatus comprises: (i) pressure reducer and flow controller means; (ii) calibration solution injection means (2); (iii) a variable dielectrophoresis drive particle filter (3), set to retain micro-organisms, and able to be turned on and off at a set frequency, periodically releasing any micro-organisms that have been retained; (iv) monitor means (4) which monitors the output of the filter (3) by optical particle detection; and (v) phase sensitive detection signal processing means for correlating an obtained turbidity signal with the state of the filter (3) and flow rate of the water through the apparatus.
