providing a first filter apparatus;
providing unfiltered water to the first filter apparatus;
filtering the unfiltered water to remove solids from the unfiltered water to produce initial filtered water, with the unfiltered water remaining with the solids;
placing the solids and a portion of the unfiltered water in a fermentation tank;
fermenting the solids within the portion of the unfiltered water to produce water containing the solids and volatile fatty acids; and
filtering the water containing the solids and volatile fatty acids using the first filter apparatus to remove the solids to produce water containing volatile fatty acids simultaneously with filtering unfiltered water.
