ABSTRACT:
An improved apparatus for purifying a liquor containing biodegradable wastes wherein the liquor is delivered serially to a number of zones. The liquor is first delivered to a clarification zone to remove suspended solids, and is then delivered to an oxidation
itrification zone where the liquor is subjected to oxidation by aerobic microorganisms. The liquor is next delivered to a denitrification zone, where it is subjected to the action of anaerobic bacteria. Both the oxidation
itrification zone and the dentrification zone contain a particular type of submerged media which comprises a multiplicity of elements freely and randomly stacked on one another to provide interstitial area therebetween. The elements have a high surface area to volume ratio in order to promote the growth of microorganisms.
