Quick question for anyone who knows septic tanks from experience...
What is the typical or average depth of the "scum" layer atop the clarified water, and how deep does it ride in the effluent?
My dilemma regards the installation of a mechanical effluent filter at the outlet of the septic tank.
I bought an effluent filter, a brand called "PolyLok" to reduce any portion of the "scum" layer at the top or any solids from the "sludge" layer at the bottom from exiting the main solids tank and entering the bio-tank or the leach field. I bought this mechanical filter to study its design. I believe that the design is insufficient after analyzing it first hand.
The lowest level of the outflow of the effluent water pipe is only six inches below the top of the open end of the top of the tee itself. I do not think that this is sufficient headroom. I believe it should be no less than ten inches and better at maybe 12 to 14 inches. Am I wrong? Or is the scum layer thinner and riding lower than I think? I just do not want any of the fats and buoyant solids to escape over the top of the tee and escape out into my secondary treatment tank or leach field. I want to be safe with my design as it is a long term, maintenance conscience engineering aspect.
If you have sincere direction on this notion, I would appreciate hearing from you!
