Abstract
The invention is a sewage treatment system with a filter apparatus enclosed within a housing. The filter operates to separate a liquid component from a solid component of the sewage. It does so by having the sewage drop onto a diffuser. The diffuser has a conical shape with its apex facing upward. The diffuser breaks up the sewage and forces the sewage to flow against the filter walls. The filter walls are liquid permeable which separates liquid from solid. The solid component then falls to the bottom of the filter walls which has as its base an incinerator plate. Hot air is then used to dry the sewage. The incinerator plate heats to a combustion temperature and burns the sewage. The ash resultant and the liquid component of the sewage is then removed from the chamber.
Claims5
An apparatus for separating sewage into a solid component and a liquid component, comprising:
- A. a housing having a top end and a bottom end and defining a chamber disposed along a vertical axis, and having an inlet port disposed about said vertical axis at said top end of said housing and defining an input sewage flow path into said chamber,
- B. an incinerator plate disposed near said bottom end of said housing and transverse to said vertical axis,
- C. a tubular screen filter having liquid permeable lateral walls extending from said incinerator plate about said vertical axis toward said top end of said housing,
- D. a diffuser having a substantially solid lateral surface having a monotonically increasing radius extending from an apex point about a central diffuser axis, and
- E. means for positioning said diffuser within said filter with said apex point uppermost with said diffuser axis substantially coaxial with said vertical axis wherein said diffuser lateral surface has a shape and position wherein gravity fed sewage incident thereon from said inlet port is deflected by said diffuser lateral surface to be incident on said lateral walls of said filter so that said liquid component of said sewage passes through said lateral surfaces to a region of said chamber outside filter and said solid compartment at said sewage is retained within a region of said chamber within said filter and substantially on said incinerator plate.
