Does anyone know method to recycling sewage to drinking water qualit , using ecological engineering methods??

The holes (yes you are correct, they are for letting water into the container) are located below the invert of the elbow on the riser pipe. So as the air forces the water level in the container down, it is released to escape up the pipe before it ever gets to the level of the inlet holes. No foot valve required.It is unclear to me why the water is simply not driven back out the hole by which it entered
There is some, but most of it stays in suspension to be pumped out to the next stage. (There is some buildup of crud on the walls of the tank, and I assume there is also some on the bottom of the tank, but I can't say how much, after 5-6 month's operation. Not enough to clog the pump anyway.)Also how are you able to aviod solid build up in the surge tank.
Also the flow pattern through the biofilter is unclear to me. The fliter effluent collects in the drum beneath. How does the solids sloughed off get returned to tha anerobic zone.
Not regularly. We used to, but then got lazy -- except when the grandkids are here and want to feed them. They are herbivorous, and find enough to eat browsing the bottom or algae or the duckweed.Do you feed your fish??
Yes. We have never heard otherwise, anyway. (Also, fwiw, I'm not sure I would describe gut bacteria as 'low level pathogens'. In most cases I'd guess the temporary upset you describe could be due to a disturbance of the gut ecosystem balance, rather than to presence of actual pathogens.)As to the questions if any pathogneicity remain in your treated water ... Do your house guests drink the recycled water without ill effect?
For the current system, I'd say it was about a week - 10 days. (They were somewhat anxious days, as I fretted about whether, or how well, it would work.) And, I also assume you are talking about the primary treatment unit, rather than the whole system, correct?Thinking back to when you first stared up the system. How long was it before it started producing clear water?
When you got the small research grant to have your system analyzed, did you publish the results.
I have a friend who owns an environmental lab. Would you be willing to send him some samples {no cost to you}.
