US 5,985,155 A · Method and apparatus for automatic adjustment of halogen production in a water treatment system

Abstract

A method and apparatus for automatically adjusting electrolytic production or feeding of a sanitizer such as halogen for treating a water body such as a swimming pool or spa. A microprocessor is responsive to sensors monitoring pH and temperature of the water body to predict demand for sanitizer which varies dependent on pH and temperature and direct a controller which automatically modifies the ON time during an ON/OFF cycle for the sanitizer production system in response to changing demand resulting from changing measurements in temperature and/or pH of the swimming pool water. The controller also modifies an ON/OFF cycle for a circulating pump when demand predicted by the microprocessor exceeds the capability of the sanitizer producer or feeder under an existing ON/OFF pump cycle.

Dependent claims

A method for treating a water body including the steps of:

(a) providing a sanitizer producer for introducing a sanitizer into such a water body;
(b) providing a pump for creating a flow between said sanitizer producer and such a water body;
(c) providing a control means for control over ON/OFF time for said sanitizer
(d) providing a sensor for monitoring parameters of such a water body;
(e) establishing an initial ON/OFF cycle for the sanitizer producer based upon a predicted demand for sanitizer under an initial set of parameters existing in such a water source;
and
(f) modifying the ON/OFF cycle for the sanitizer producer automatically based upon changes in said monitored parameters from said initial set of parameters.
