Wastewater evaporator

A wastewater evaporator for the evaporation of liquid effluent from a septic system, comprising:

• an evaporator tank having an internal volume;
• a plurality of evaporator trays disposed within the evaporator tank, the evaporator trays being spaced apart from one another in a vertical array, the array having an uppermost tray, a lowermost tray, and at least one intermediate tray disposed between the uppermost tray and the lowermost tray, wherein each of the evaporator trays has a right side portion and a left side portion;
• each of the plurality of evaporator trays consisting of an overflow drain disposed in each of the evaporator trays, the overflow drains each having an outlet positioned to discharge effluent into the next lower tray in the vertical array, wherein the overflow drains are staggered between those in the right side portion to those in the left side portion whereby the effluent flows through the overflow drains from an uppermost tray sequentially to each successive intermediate tray in a serpentine configuration, and then to the lowermost tray, further wherein at least one of the evaporator trays includes an ultrasonic agitator;
• an air intake plenum disposed in the evaporator tank adjacent the evaporator trays;
• an air intake manifold disposed in the plenum, the manifold being disposed to direct a flow of air directly over each of the trays in the vertical array such that the flow of air passes across and between each of the trays and the surfaces of the effluent therein thereby evaporating the liquid effluent;
• an air pump disposed above the plenum and manifold, the air pump being adapted to deliver an airflow through the plenum and manifold over each of the evaporator trays;
• and
• an air outlet vent disposed above the evaporator tank to exhaust air from the evaporator tank.
