ABSTRACT:
A process and system for reducing the biochemical oxygen demand and suspended solids levels of impure water and creating a wild life habitat. A number of containers are arranged in series with interconnecting lines through which the water flows. The containers include openings with clusters of bark fibers projecting through the same. The fibers serve to attract and hold nutrient deposition in the form of colloidal wastes and the like and as a safe habitat for microorganisms which feed on such wastes and as a capillary system for the passage of clarified water formed in the bark fibers. The containers are disposed underground. Roots from neighboring plants are attracted to the bark clusters and grow into the containers. In a preferred embodiment, the above container system is utilized as an advanced secondary treatment system for water previously treated in an open body of water in which a number of float units are secured carrying bark fibers which promote a trophic balance between minute animal feeders and excessive colloidal nutrient depositions in the water body.
