ABSTRACT:
A thin film electrocoagulation liquid treatment apparatus includes a nonconductive housing formed by opposite top and bottom walls, opposite side walls, and tubular end members with slots therethrough which define a treatment chamber. Pluralities of elongated electrodes extend between the side walls and are spaced along the top and bottom walls in spaced apart interleaved relation to define a serpentine fluid treatment path. The tubular end members form fluid connections, one end member receiving liquid to be treated from a supply conduit and the other discharging the treated liquid to a discharge conduit. A DC power supply has opposite poles thereof connected respectively to the sets of electrodes in such a manner that the polarity on succeeding electrodes is opposite. The first two electrodes in the flow direction of the fluid path are preferably connected to the negative pole of the power supply. A treatment process employing the treater apparatus includes pressure differential monitoring across the treater and flow direction reversal to avoid clogging the treater and temperature differential monitoring across the treater to optimize the consumption of electrical power by the process.
