PCT No. PCT/SE94/00007 Sec. 371 Date Jun. 29, 1995 Sec. 102(e) Date Jun. 29, 1995 PCT Filed Jan. 5, 1994 PCT Pub. No. WO94/15876 PCT Pub. Date Jul. 21, 1994A water purifier which works in accordance with the membrane distillation principle includes a degassor for degassing incoming crude water prior to commencing the membrane distillation precess; a membrane for the membrane distillation of degassed water; and an outlet which functions to discharge a residual quantity of degassed undistilled water when a degassed undistilled water level has fallen to a predetermined lower level in a container which receives the crude water to be purified. The container is provided with an upper level sensor and a lower level sensor and a temperature sensor. The upper level sensor functions to activate the start of circulator for the circulation of crude water through the degassor, and also to activate the start of crude water heater. When the level of water in the container falls, the lower level sensor functions to activate opening of the outlet means so as to discharge remaining undistilled water. The temperature sensor functions to cause circulation to the degassor to stop and to cause the circulation of degassed water to the membrane to commence for distillation of degassed water when a predetermined water temperature is reached. |
