Apparatus for the cleaning of water in which the apparatus is positioned, through the biological oxidation of microbiologically digestable compounds within the water, comprising in combination: filter means positionable in the water to be cleaned, the filter means having pluralities of surfaces providing high surface area per volume; biological agents supported on the surfaces for cleaning the water in which it is positioned by digesting microbiologically digestable compounds in the water flowing through the filter means; locating means for locating the filter means spaced from the bottom of the water to be cleaned; pump means with a discharge component for effecting the flow of a pressurized fluid through the water and across the surfaces in circuitous paths for the cleaning and redistribution of the water; and positioning means to position the discharge component beneath the filter means and above the bottom of the water for directing the flow of water through the filter means for cleaning purposes.
