Abstract:
An electrode assembly for treating a flowing fluid with an electrostatic field comprising:(a) a conduit having an inside surface adapted to operate as a negatively charged surface for an electrostatic field, the conduit further adapted to contain the flowing fluid:(b) an electrode adapted to be located generally within an axis of the conduit and adapted to maintain a potential difference between the electrode and the inside surface of the conduit of over 10,000 volts DC and a current in the order of microamps, such that a negative pole of a DC power supply is electrically connected to the inside surface of the conduit and the electrode is electrically connected with a positive pole of the power supply;(c) the electrode substantially having the shape of a cylindrical rod and having a thin surface layer sealing from the flowing liquid successive adjacent layers of a cylindrical dielectric layer and cylindrical conductor layer;(d) the dielectric layer comprising a substantially thin polymer layer of a polymer selected from the group consisting of polyvinylidene fluoride and poly-paraphenylene terephthalamide close to and in electrical field contact with the conductor, and(e) the conductor comprising a hollow cylinder electrically connected to the positive pole of the power supply.
