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.

Abstract: A self-regulating porous heater regulates the temperature of fluid passing through it. This device includes at least one layer of a porous material which has a magnetic permeability inversely related to temperature over a given range. Due to conductor skin effects, changes in permeability cause changes in the depth of penetration of alternating current passing through the magnetic layer. Changes in the depth of penetration, in turn, result in changes in resistance--the less the depth the greater the resistance--and in I.sup.2 R Joule heat. The combined result of these effects is to provide more heat where the temperature of the fluid and the layer through which the fluid flows is below a specified temperature which is related to the Curie temperature of the layer. Significantly, by properly defining pore dimensions, the heater device can filter contaminants from a fluid as it flows therethrough. In a preferred mode, a porous heater device is included in a chemical reaction chamber.
