Abstract
A residence (13) discharges its waste water into a septic tank (10). A pump (18) draws waste from the tank's liquid layer and feeds it to a distiller (22) as distiller feed. The distiller (22) divides the distiller feed into distillate and distiller residue. The distiller residue is returned to the septic tank (10), whereas the distillate is reused or discharged into a leach field. In either case, the adverse environmental effects of leach-field use are largely eliminated.
Claims54
A method of processing waste that includes:
- A) directing waste to flow from a waste source into a septic tank;
- B) drawing waste from the septic tank into a distiller as distiller feed;
- C) employing the distiller to separate the distiller feed into distillate and distiller residue;
- and
- D) returning most of the distiller residue into the septic tank without returning most of the distillate thereto.
2 more elements
A method of processing waste that includes:
- A) directing waste to flow from a waste source into the main septic-tank inlet of a septic tank having a main septic-tank inlet, a main septic-tank outlet, and an auxiliary septic-tank outlet;
- B) drawing waste from the septic tank through the auxiliary septic-tank outlet into a distiller as distiller feed;
- C) employing the distiller to separate the distiller feed into distillate and distiller residue;
- and
- D) directing waste to flow out of the septic tank through the main septic-tank outlet.
2 more elements
A method of processing waste that includes:
- A) directing waste to flow from a waste source into a septic tank;
- B) drawing waste through a filter from the septic tank into a vapor-compression distiller as distiller feed, the filter preventing the distiller feed from including particulates greater than a predetermined maximum size;
- and
- C) employing the distiller to separate the distiller feed into distillate and distiller residue.
1 more element
A waste-processing system that includes:
- A) a source of domestic waste;
- B) a septic tank;
- C) a main inlet conduit leading from the source into the septic tank;
- D) a distiller that receives waste from the septic tank as distiller feed and separates it into distillate and distiller residue;
- E) a return conduit that conducts most of the distiller residue into the septic tank;
- and
- F) a distillate conduit that conducts most of the distillate to a destination other than the septic tank.
4 more elements
A waste-processing system that includes:
- A) a source of domestic waste;
- B) a septic tank having a main septic-tank inlet and a main septic-tank outlet through which waste can drain from the septic tank;
- C) a main inlet conduit leading from the source into the septic tank through the main septic-tank inlet;
- D) a vapor-compression distiller that receives waste from the septic tank as distiller feed and separates it into distillate and distiller residue;
- and
- E) a pump that draws waste from the septic tank into the distiller as distiller feed.

- B) a septic tank having a main septic-tank inlet and a main septic-tank outlet through which waste can drain from the septic tank;
- C) a main inlet conduit leading from the source into the septic tank through the main septic-tank inlet;
- D) a vapor-compression distiller that receives waste from the septic tank through a distiller-feed path as distiller feed and separates it into distillate and distiller residue;
- and
- E) a filter interposed in the distiller-feed path to prevent the distiller feed from including particulates greater than a predetermined maximum size.
