The present invention relates to reducing and preventing biofouling in plants utilizing water, such as seawater with biological organisms, without causing corrosion, chemical or other harmful reactions from additive or environmental release problems. Such actuation mechanisms include, for example, desalination plants, power plants, oil field water injection plants and marine or offshore platform fire water systems. For example, in the desalination plant of FIG. 1, the bioadhesive reduction methods and apparatus of the present invention, with a copper ion, an oxidant (ie, chlorine ion or ozone) source, a copper ion source, and relatively at a suitable time to form a treatment additive It has an addition chamber 25 for delivering a low addition level of oxidant. The flow connector 29 connects the addition chamber 25 to various points along the pipe of the desalination plant. In order to deliver a treatment additive of a predetermined composition to a point along the pipe at a predetermined time and at a predetermined concentration, the controller 31 is provided with a valve 33 along the flow connector 29 which operates in an addition chamber and a sequential target addition mode. To control operation. |
