Abstract

An apparatus for destroying bacterial pathogens including at least one pair of electrodes secured in a housing configured to constrain flow of water through the region between the electrodes. In one construction, the electrodes are supported in a tube with sides of each member of an electrode pair conforming to the inner surface of the tube and electrode surfaces form a slotted space through which the water passes. In another constrcuction, one electrode is a tube and the other electrode is a rod supported concentrically inside the tube. The treated fluid passes axially through the space between the electrodes. A conductivity meter and flow meter applies a conductivity signal and a flow rate signal to maintain the field in a value that is not too excessive so as to prevent undesired reactions. The electrodes and space between the electrodes are also subject to a magnetic field which reduces rate of deposition of calacerous deposits on the electrode surfaces thereby extending the period of time between required cleaning of the electrodes. The electrodes can be simple slabs or screens or both. The electrodes are preferably tin, titanium, brass, iron or stainless steel.
