ABSTRACT:
A system, a device and a method for maintaining water quality in a pool or similar water container for use by people which is characterized in that a pressure sensor is arranged to sense the pressure variations inside a main water container1and to provide a pressure variation signal to a control and processing unit3. The control and processing unit is connected with a dispensing module and is adapted to generate and transfer control signals to said dispensing modules. The control signal depends on the detected pressure variation signal. The system for water treatment comprises also a water treatment circulation loop3A-Dat least one controllable chemical dispensing module8A-D, 9A-D. The circulation loop is adapted to pump water from the main water container1, around the circulation loop3A-D, and back into the main water container1via the dispensing module for dispensing a chemical treatment agent.
