ABSTRACT:
This invention most generally relates to a method of and a device/apparatus for use in precipitating out suspended solids, particularly those found in septic tanks, and having the particular objectives, features and advantages of: 1) Special formed collection and support structure which will not restrict or inhibit the flow-through of liquid in a septic tank; 2) Liquid flow directing devices causing undulating and directed liquid flow; 3) Compatibility with existing septic tanks; 4) Collection panels with collection surfaces with-current and counter current to liquid flow within the tank and permitting cross current flow-through of the panels; 5) Special structure adaptable to be easily removed and cleaned. Even more particularly, the invention is directed to a septic tank maze apparatus comprising means for causing the incoming liquid having the suspended materials suspended therein to flow in an undulating path in a direction substantially parallel to collection surfaces of collection panels. The suspended solids collect, at least in part, simply due to contacting the panel collection surface. The collection panels collection surfaces have perforations therethrough to allow for minimal perpendicular flow (higher resistance path) through of liquid and also to reduce the surface area of the collection surface resulting in the dislodging of the collected solids when the mass becomes substantially large. The globules--the locally accumulated collected solids--will either fall from the collection surface to the bottom of the septic tank or will float off and remain in the tank and not outflow into the leach system. More particularly, the collection panels are preferably used in multiples within the septic tank and have flow directing openings located in a manner so as to cause the liquid flow to be undulating through the septic tank from the inflow to the outflow. There is also provided means for keeping the collection panels optimally located within the septic tank.
