<p>A water treatment apparatus 10 comprises a filter 12, a biomonitor device 28, a treatment device 18, and a control device 38. The apparatus is operable to receive water and to filter it with the filter. The treatment device, such as an ultraviolet treatment device, is operable to treat the filtered water. The biomonitor device determines the presence of organisms in the filtered water relative to a predefined threshold and provides a data signal 36 to the control device in response thereto. The control device provides a control signal 39 relating to the data signal, for controlling the treatment of the filtered water by the treatment device. Preferably, the apparatus treats ballast water. The biomonitor device may have a flow cytometer 34 for quantifying and/or determining a species of the organisms. Suitably, the biomonitor device has a concentrator device, such as a dielectrophoresis device 30, for concentrating the organisms in the filtered water.</p> |
