ABSTRACT:
Apparatus and method are provided for the treatment of potable water. A non-pressurized chlorinator has a first chamber which receives solid calcium hypochlorite tablets. A portion of the potable water flows into the first chamber to produce a chlorine solution in a second chamber of the chlorinator. An eductor is connected in a potable water flow line and draws the chlorine solution from the second chamber to chlorinate the water. A third chamber in fluid communication with the second chamber includes level sensors to control the flow of water into the chlorinator. The use of pumps for injection of chlorine into the potable water supply is eliminated thereby providing a highly reliable and cost effective system. The system is particularly advantageous in that it does not rely upon the use of chlorine gas nor is it necessary to transport or store highly unstable liquid chlorine.
