A METHOD AND A SYSTEM FOR MANAGING A RESERVOIR OF WATER REQUIRING RECIRCULATION AT TIME INTERVALS

摘要

A method of managing a reservoir of water having a recirculating arrangement for recirculating water at frequent time intervals is disclosed. The method includes starting a productive recirculation of water within the reservoir by means of the recirculating pump, and sensing control parameter/s relating to the quality of water that are selected from: a level of disinfectant, a pH level, a water turbidity level, or a biological count level. The productive recirculation of water by the recirculating pump is continued until each sensed control parameter has reached its target level in the water. In a power saving management mode the productive recirculation of water by the recirculating arrangement is stopped when each sensed control parameter has reached its target level. Instead in a minimum run time mode the productive recirculation is only stopped when this minimum run time has been completed and each sensed control parameter has reached its target level. A management system for installation on a reservoir to carry out the method is also disclosed.
