Abstract
Apparatus for treatment of septic tank effluent to remove suspended particles for clarifying and purifying the water prior to discharge into the leaching field or for use for other purposes. The apparatus, which is small enough to be conveniently installed in individual households, comprises a vertical main tank, flocculation material supply means to form flocs for combining with suspended solids in the unclarified water introduced into the main tank, a water electrolysis unit in the main tank for producing gaseous bubbles to which the flocs become attached and which rise to the surface where the entrapped solids are removed and returned to the septic tank, and a filter device at the bottom of the main tank for removing remaining precipitated flocs with entrapped solids. The anode of the electrolysis unit is made of aluminum to provide aluminum hydroxide as a flocculating agent.
