Abstract: The present disclosure relates to a water purification apparatus that comprises a reverse osmosis device, RO-device, producing a purified water flow and to a corresponding method. The proposed method comprises detecting at least one fluid property of purified water in the purified water path and regulating a flow rate of water in the recirculation path to fulfil one or more predetermined criteria of the purified water in the purified water path, based on the at least one detected fluid property. The present disclosure also relates to a computer program and a computer program product implementing the method.

Abstract: A water purification apparatus (1) comprising a RO-device (2) comprising a RO-membrane (2a). The RO-device (2) is configured to receive inlet water to be purified from an inlet path (19) and produce permeate water into a permeate path (22) and reject water into a reject path (23). The apparatus (1) also comprises a recirculation path (24) arranged to recirculate reject water from the reject path (23) to the inlet water. The apparatus further comprises a cooling arrangement (30) comprising a cooling device (31, 39). The cooling arrangement (30) is configured to cool the recirculated reject water in the recirculation path (24) with the cooling device (31, 39), and a control arrangement (40) configured to control the cooling arrangement (30) to cool the recirculated reject water in the recirculation path (24) in order to cool the RO-membrane (2a).

Abstract: A method for controlling water purification, and a water purification apparatus (1). The apparatus (1) comprises a reverse osmosis membrane (3a) configured to receive feed water from a feed pump (5), and to produce permeate water and reject water. The method comprises measuring (S1) a property indicative of an inlet water quality Cinlet of inlet water to the feed pump (5), and determining (S2) a target recovery for the water purification based on the property indicative of the inlet water quality. The method further comprises controlling (S3) a feed pump speed to a predetermined speed, or to a speed determined based on a relation between the feed pump speed, the inlet water quality Cinlet and a target permeate water quality Cper, based on the inlet water quality.

Abstract: A water purification apparatus (1) comprising a Reverse Osmosis, RO, device (26). The RO device (26) comprises a RO membrane (26a) and a feed pump (23). The apparatus (1) also comprises a recirculation mechanism (33) arranged to recirculate a portion of the reject water to the feed water, a temperature sensor device arranged to measure a temperature indicative of the temperature of the RO membrane (26a), and a flow rate sensor device arranged to measure a flow rate indicative of the permeate flow rate of the permeate water. The apparatus (1) further comprises a control arrangement (50) configured to control recirculation to achieve a predetermined recovery ratio.
