1 Small Community Wastewater Alternatives Section V Advanced Treatment

2 Advanced Treatment Process House sewer conveys sewage to aerobic treatment unit Aerobic treatment unit treats the sewage similar to a sewer plant (secondary treatment) Effluent pipe conveys treated effluent to absorption area Absorption area now serves primarily as a dispersal area for treated effluent Courtesy of OTN

3 Most Advanced Treatment Technologies Produce “Secondary” or Better Quality Effluent!

4 Advanced Treatment Pre-treatment of wastewater –Usually requires dosing –Often requires electric –Always requires maintenance Applicable to: –Difficult sites –Sensitive environments

5  May be required by design or to “lift” wastewater to the absorption area  Delivers a calculated “dose” of wastewater  Allows for rest periods, promotes aerated and unsaturated soil conditions  Extends system life Dosing Options

6 Advanced Treatment Aerobic Treatment Units (ATU) Media Filters: –sand –textile –peat –foam Nutrient Reduction

7 Advanced Treatment Difficult Sites
