Abstract: Disclosed herein is a water purification apparatus capable of being cleaned at a point of care, and methods for cleaning the water purification apparatus at the point of care. The water purification apparatus and the methods provide an efficient use of a heater for heat disinfection the water purification apparatus, e.g. by recirculating heated fluid to further heat the fluid. Several different cleaning programs are provided that may be utilized for cleaning different parts of the water purification apparatus.

Abstract: A water purification apparatus (300) capable of being cleaned at a point of care, and methods for cleaning the water purification apparatus (300) at the point of care. The water purification apparatus (300) and the methods provide an efficient use of a heater (302) for heat disinfection the water purification apparatus (300), e.g. by recirculating heated fluid to further heat the fluid. Several different cleaning programs are provided that may be utilized for cleaning different parts of the water purification apparatus (300).

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).
