Electroflocculation process and apparatus

摘要: The invention provides an electroflocculation process for producing potable water from impure water, comprising forming trivalent ions in Situ by electrolysis of metallic electrodes (16) Selected from the group consisting of metal lic aluminum electrodes and metallic iron electrodes, wherein water to be treated is caused to ascend Sequentially through apertures (22) provided in a Stack of parallel metal lic plates (16) Serving as said electrodes, each plate being charged with a polarity opposite to plates adjacent thereto, apertures of adjacent plates being vertically misaligned, whereby turbulent flow and mixing is created by the Sequen tial passage of Said water to be treated from the aperture of the lowest of Said plates to the apertures of the plates thereabove to exit from the highest of Said plates.
