<p>An apparatus for treating water comprises a conduit assembly for receiving waste water from a downstream inlet and for providing treated water out of an upstream outlet. The conduit assembly comprises a plurality of substantially vertical conduits in fluid communication providing forwaterto flow in an alternating downward and upward pathway therein. A medium for providing bacterial growth being is mounted within the conduit assembly. The medium comprises a plurality of substrate surfaces stacked along the vertical length of at least one conduit. Each substrate surface extends along the width of the conduit and provides for bacterial growth thereon. The apparatus includes a housing defining at least one chamber for receiving the conduit assembly therein.</p> |
