I have been considering ways to take aerated effluent from an added aeration tank and reintroducing it to the septic tank at a continuous slow controlled rate so's not to create TSS. My latest thought is I could place an upside down funnel with a hose attached and positioned over my aggressive aerator, in the aeration tank. I think it would generate enough pressure to create flow. I could then add a simple irrigation valve to control the flow. I could try trickling this aerated effluent back onto the filter in the septic tank ( like back flushing ) and/or reintroduce it into the first chamber. Either way I think it could be controlled and reintroduced in a way that won't cause TSS. I'm excited about this idea because it would run passively off the energy supplied by the aeration pump.
