Abstract: Disclosed is a system and method for treating nitrogen-rich effluent water utilizing a partially aerobic bioreactor. The bioreactor comprises a first housing having a plurality of openings and a second housing positioned within the first housing, the second housing directing a flow of effluent against the openings. When the effluent is circulated through the bioreactor it contacts aerobic microorganisms carried within the first housing for metabolizing nitrogenous compounds.

Abstract: An irrigation control system is disclosed for controlling the irrigation of horticultural plants or crops grown in containers. The system includes a beam assembly for supporting the plant media system and a load cell for providing an electrical output signal proportional to the load applied to the beam assembly by the plant media system. The load cell is interfaced with a microcomputer which executes a control program of the present invention. The control program reads the signal from the load cell at selected intervals and signals for an irrigation event if the current weight of the plant media system is less than a predetermined base weight. A new predetermined base weight is calculated and reset after each irrigation event.
