Abstract
A process for treating water to remove concentrations of nutrients and pollutants using ozone prior or after the water is exposed to natural filtration by periphyton or other aquatic plants. A system employs a deep water tank containing water to be treated is injected at the bottom with concentrated ozonated water to expose the water to be treated to ozone. The treated water exits from the tope of the tank whereby it is flowed over aquatic plant system to remove the undesired matter, such as pesticides. The process can be repeated successively to further treat the water if desired.
Claims14
A method of treating water comprising the steps of:
- (a) exposing influent comprising water desired to be treated to ozone in sufficient quantity to disrupt cell walls of undesired microorganisms therein, thereby releasing nutrients from within the microorganisms in a form amenable to bioassimilation, the ozone further in sufficient quantity to oxidize toxic, humic, and tannic compounds to a form amenable to bioassimilation;
- and
- (b) contacting aquatic plants with the ozone-exposed water, the aquatic plants adapted to remove the released and oxidized nutrients therefrom.
A system for treating water containing excess nutrients comprising:
- means for exposing influent comprising water desired to be treated to ozone in sufficient quantity to disrupt cell walls of undesired microorganisms therein, thereby releasing nutrients from within the microorganisms in a form amenable to bioassimilation, the ozone further in sufficient quantity to oxidize toxic, humic, and tannic compounds to a form amenable to bioassimilation;
- aquatic plants adapted to remove the released nutrients and the oxidized compounds from the ozone-exposed water;
- and
- means for directing the ozone-exposed water from the water-exposing means to the aquatic plants.
