<p>An evaporator, used as an alternative means of disposing of biological wastes or wastes containing biological matter from, for example, oil flush toilets or minimum flush toilets or in any biological waste treatment system. The evaporator includes a storage tank (2) containing the waste with aeration means (7,8) employed to expose large surface areas of the waste to free air and a heat source (5) to supply sufficient heat energy to equal the heat of vaporization required for evaporation of the water into the air, and maintain a temperature at which evaporation and biological activity take place. Saturated air at an elevated temperature leaves the tank through a vent (3). As waste is introduced, heat and air are added to promote evaporation and, thermophilic aerobic biological activity. The air supply is provided at a rate commensurate with the supply of waste material, and the temperature is adjusted (for example to 58 DEG C but below 100 DEG C) to accommodate a particular strain of thermophilic bacteria, ambient air conditions, percent of organic substances or other criteria that may be established as a function of design criteria.</p> |
