Abstract: A Water and Wastewater Treatment Aerated Mini-Dosing air-lift pump System and filter housing, that replaces the conventional dosing pump, controls and additional Tank. It is adaptable to all access ports and uniquely smaller than a 3? inspection port and is integrally positioned in an existing or new raw water pretreatment or pump tank. It aerates the source pool thereby mitigating: H2SO4 gases, odors and source pool BOD5. The system communicates with an above ground aerator and optional controls and in it's plurality supplies dissolved and free oxygen to the pump, housing, effluent and the source pool, with surge protection and scum mitigation. Mini-metering and, low pressure, extended cycle durations increase the average microbial production balance and microbial Ratio to nutrients BOD. The raw sewage tank no longer requires gas removal prior to inspection due to oxic and anoxic microbial processes that mitigates H2SO4 gases.
