Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A water purification apparatus for producing purified water, the water purification apparatus comprising: a tank including at least one fluid level sensor; a pre-treatment fluid path configured to fluidly couple the tank to a fluid source; at least one valve located along the pre-treatment fluid path; a feed fluid path fluidly coupled to the tank and configured to receive fluid from the tank; a pump located along the feed fluid path for pumping fluid from the tank; a heater fluidly coupled to the feed fluid path and arranged to heat fluid from the tank; a recirculation fluid path fluidly coupled to the heater to receive heated fluid and transport the heated fluid to the tank; and a control unit configured to control cleaning of the water purification apparatus, the control unit being configured to cause the water purification apparatus to: cause the at least one valve to open to cause the tank to fill with fluid from the fluid source, receive a signal from the at least one fluid level sensor indicative that a fluid level in the tank has reached a predetermined level, cause the at least one valve to close after receiving the signal from the at least one fluid level sensor, cause the pump to circulate fluid through the feed fluid path, the heater, and the recirculation fluid path to heat the fluid to fulfill a temperature dependent disinfection criterion.
