Abstract
Periphyton filtration is a known method for performing bioremediation of polluted water, removing nutrients from the influent on which the attached algae thrive. The present system improves upon this method by adding a strong oxidizer to the influent, and, in some cases, to the effluent, to make organically bound nutrients available to a target culture of periphyton or aquatic plants to reduce the population of undesirable microinvertebrates, to make organically bound nutrients available to the periphyton, and to reduce the level of toxic compounds. A particular embodiment comprises ozonating the water. A pesticide may be added to control insect populations.
Claims37
A method of treating water comprising the steps of:
- exposing water desired to be treated to ozone in sufficient quantityto reduce a concentration of undesired microorganisms therein;
- and
- flowing the water over a colony of attached algae to remove undesired matter therefrom.
A system for treating water comprising:
- means for exposing water desired to be treated to ozone in sufficient quantity to reduce a concentration of undesired microorganisms therein and to liberate available nutrients therefrom;
- a colony of attached algae for removing undesired matter from the ozone-exposed water;
- and
- means for directing the ozone-exposed water from the water-exposing means to the algal colony.
