<p>PURPOSE:To decrease dissipattion of heat and to save fuel cost and water by purifying and regenerating the residual hot water after bathing with a coagulating sedimentation method while insulating it with an insulating material. CONSTITUTION:The residual hot water after bathing is transferred from a bathtub to an insulating hot water storage tank 1 by a hot water suction pump 6. Slaked lime or slaked lime solution is poured into the hot water storage tank 1 and agitated by an agitator 8 and further poly aluminum chloride is poured and the mixture is agitated. The precipitate coagulated and precipitates is carried up in a tank filter 2 together with transparent hot water and filtered by a filter 3. The hot water purified and regenerated is transferred to the bathtub by a hot water feed pump 7 and reused for bathing. And it is also used for the sink and if necessary, it is sterilized by a chemical, etc. It will be sufficient if the filter is properly replaced. And the filter is easy to replace and excellent in insulating property and purifying power.</p> |
