Trickling SOG filter

The SOG trickling filter is a waste water treatment process that has evolved from the need to treat small and sporadic amounts of domestic sewage.   Unlike most conventional sewage treatment plants, the SOG filter makes use of plants, earthworms, fungus and bacteria to treat sewage.  By spreading the type of organism activity, a larger range of variable flow and load is possible.  The range in size of treatment organism also facilitates the conversion of sewage to heat and gas as opposed to mere biomass.  In the SOG filter there are pockets of aerobic, anoxic and anaerobic zones.  Organisms live in the various zones performing selective functions including dissolved organic material degradation (COD reduction), conversion of ammonia to nitrate (nitrification) and removal of nitrate (denitrification).
