Abstract: A method of providing at least two outlet purified water streams from a water purification system by providing a first purified water into a first reservoir able to provide an outlet purified water stream. At least a portion of the first purified water is passed from the first reservoir through a water purification process to provide an ultra-purified water stream. The ultra-purified water stream is passed to a second reservoir. An excess of ultra-purified water is provided into the second reservoir beyond a pre-determined quantity, The excess ultra-purified water in the second reservoir is allowed to flow from the second reservoir into the first reservoir. An outlet from the water purification system of an ultra-purified water stream is provided from the second reservoir.

Abstract: A system is disclosed for facilitating maintenance of water treatment apparatus at multiple locations and which include multiple components designed with an operational life that is greater than an apparatus exchange duration. The system includes tracking the usage of each component and determining an exchange date for an existing apparatus. A refurbished apparatus is sent to the location when the existing apparatus is at or near its exchange date. The operational life remaining for each component in the existing apparatus is determined based on the usage of the component. Each component that has operational life remaining that is less than the exchange duration for use as a refurbished apparatus is removed and replaced or refurbished so as to create a refurbished unit.

Abstract: A clinical analyser wastewater treatment apparatus is disclosed including a carbonator section. Preferably there is also an anodic oxidation section and a UV oxidation section, as well as a heavy metal removal section. The anodic oxidation section may include a conductive diamond anode. The apparatus may include a measurement device downstream of the carbonator section and a control system to control the operation of the carbonator. The measurement device is preferably a pH sensor.

Abstract: An automated method for determining the cleaning operation of a water treatment or water distribution apparatus or system to which one or more substances are added, the method comprising the steps of: (a) conducting one or more measurements of a property of the or an added substance; (b) comparing the property measurement s) from step (a) with at least one reference value for that property; and (c) determining when the comparison in step (b) is within, above or below a pre-determined range or level for that property. The determination in step (c) can consider whether the cleaning operation has been successfully carried out. The present invention automates and therefore optimizes the cleaning operation of the water treatment or distribution apparatus or system such that expensive periods of non-operation during sanitization or cleaning are minimized both in terms of frequency and duration.

Abstract: A method of manufacturing a water treatment apparatus having one or more chambers comprising the step of: filling at least one chamber with ion exchanger resin; wherein at least one ion exchanger resin is dry. Preferably, the dry ion exchange resin has a water content of 0-40 wt %, preferably 0-20 wt %, and more preferably 0-10 wt %, such that the volume of the dry ion exchange resin is 25-50 vol % less than the volume of the same ion exchange resin in a moist or wetted form. One form of suitable water treatment apparatus is an EDI apparatus comprising a plurality of chambers to form a stack, for the purification of the water. The present invention provides an easier method of filling of chambers compared with the use of wetted or moist resins, and ‘over filling’ of the cells of water treatment apparatus.
