The apparatus and method of the present invention may be readily-sized and configured depending upon the amount and constituent(s) of the wastewater to be treated. In a first embodiment, the apparatus and method of the present invention is designed to be a zero discharge system in which no wastewater will be discharged or land applied. In use, the apparatus and method of the first embodiment may actually require addition of make-up water during periods of low rainfall to make up water losses due to evaporation and drift. It is contemplated that the only byproduct of the apparatus and method of the first embodiment may be a beneficial sludge if a sufficient number of installations are operated. In a second embodiment, the apparatus and method of the present invention provides a treatment system capable of reducing the nutrient loading in a step-wise fashion so that the wastewater can be used from different steps of treatment in order to apply the varying nutrient loads required by crops on a seasonal basis.

SUMMARY OF THE INVENTION For the purposes of summarizing the invention, the present invention is drawn to a unique apparatus and method for treating and reusing the wastewater discharged from agricultural animal farms. The apparatus and method of the present invention may be readily sized and configured depending upon the amount and constituent(s) of the wastewater to be treated. In a first embodiment, the apparatus and method of the present invention is designed to be a zero discharge system in which no wastewater will be discharged or land applied. In use, the apparatus and method of the first embodiment may actually require addition of make-up water during periods of low rainfall to make-up water losses due to evaporation and drift. It is contemplated that the only byproduct of the apparatus and method of the first embodiment may be a beneficial organic fertilizer if a sufficient number of installations are operated.
