Title:
AUTOMATIC CONTROL OF RESIDUAL CHLORINE AND PH VALUE OF STORED WATER
Document Type and Number:
Japanese Patent JP3201536
Kind Code:
B2
Abstract:
PURPOSE: To make it possible to control a residual chlorine in a stored water and its pH value constantly in an optimal state by combining a quantitative dispenser with high resistance against a solid chlorine agent with a pH adjustment agent, a residual chlorine detection part and a pH value detection part.
CONSTITUTION: Water is constantly extracted to a detection part 6 from a circulation line 1, then a residual free chlorine and a pH value are measured, and if these values are below a standard level, a solid chlorine agent and/or a solid pH value adjustment agent are supplied to their respective dissolution tanks 12 and/or 11, using a chlorine agent quantitative dispenser 8 and/or a pH value adjustment agent dispenser 7. A drive motor 19 is started by a signal of agent addition to rotate a round bar 20 and fill the groove 30 of the round bar with the solid agent. With this action, the round bar is moved along a holding plate and thereby, the solid agent is allowed to drop down from a rectangular space below. Thus, it is possible to maintain the stored water in a tank in an optimal state for a long time.
