Monitoring and optimizing water pre-treatment by ultraviolet illumination and addition of chemical agents

A monitoring module in a water treatment system for pre-treating water delivered to a water treatment sub-system, the monitoring module configured to:

• receive measurements comprising at least a pressure difference over a filtration unit of the water treatment system and/or a pressure difference over the water treatment sub-system,
• determine, based on the measurements, a type and extent of degradation of membranes of the water treatment sub-system due to biological fouling and/or mineral scaling, and
• adjust, based on the determined type and extent of the degradation, a UV dose applied by a UV treatment module to the delivered water to treat biological fouling and/or an addition of chemicals to the delivered water to treat mineral scaling—to maximize a performance of the water treatment sub-system.

A method of managing water pre-treatment of delivered water to a water treatment sub-system, the method comprising:

• receiving measurements comprising at least a filtering pressure difference and/or a pressure difference over the water treatment sub-system,
• determining, based on the measurements, a type and extent of degradation of membranes of the water treatment sub-system due to biological fouling and/or mineral scaling, and
• adjusting, based on the determined type and extent of the degradation, a UV dose applied to the delivered water to treat biological fouling and/or addition of chemicals to the delivered water to treat mineral scaling—to maximize a performance of the water treatment sub-system.

A computer program product comprising a non-transitory computer readable storage medium having computer readable program embodied therewith, the computer readable program comprising:

• computer readable program configured to receive measurements comprising at least a filtering pressure difference and/or a pressure difference over the water treatment sub-system,
• computer readable program configured to determine, based on the measurements, a type and extent of degradation of membranes of the water treatment sub-system due to biological fouling and/or mineral scaling, and
• computer readable program configured to adjust, based on the determined type and extent of the degradation, a UV dose applied to the delivered water to treat biological fouling and/or addition of chemicals to the delivered water to treat mineral scaling—to maximize a performance of the water treatment sub-system.
