A portable water conditioning system is provided that includes a water conditioner, a first sensor, a second sensor, and a controller. The water conditioner has a plurality of conditioning stages that condition water. The plurality of conditioning stages include, in a direction of flow of the water through the water conditioner, a reverse osmosis stage and a deionizing stage. The first sensor detects a first condition of the water before the reverse osmosis stage. The second sensor detects a second condition of the water after the reverse osmosis stage. The controller is in communication with the first and second sensors and determines a health status of the reverse osmosis stage based the first and second conditions. The first and second conditions each include a level of total dissolved solids of the water.

A control system suppresses biological growth, scale formation and/or corrosion in a recirculating evaporative cooling facility (1). The control system is configured to: monitor a value (C) from at least one sensor (19a-l). The value is indicative of an ion concentration in a cooling liquid of the recirculating evaporative cooling facility (1). The control system controls at least one flow regulation device (21, 23) for regulating the hydraulic operation of at least one de-ionising unit (13) of the recirculating evaporative cooling facility (1). The control system is configured to control at least one parameter of hydraulic operation of the at least one de-ionising unit (13) based on an adaptive target water saving as long as the monitored value (C) does not pass a pre-determined threshold.

A control system for a water treatment apparatus that includes a control valve assembly having a servo chamber in which a stationary port defining signal ports is located. A regeneration control disc sealingly engages and rotates on a planar surface of the port disc and selectively communicates fluid signals to water pressure operated components within the control valve. An electric motor located in a dry chamber is operatively coupled to the regeneration control disc and rotates the disc during a regeneration cycle. An encoder coupled to the control disc monitors its position and movement. A turbine assembly monitors water treated or to be treated and is electronically coupled to a regeneration controller. A sensor emits pulses related to rotation of the usage turbine and communicates these pulses to the controller which uses this information to determine when a regeneration is needed whereupon the drive motor is appropriately energized.

A decision support system and method can be used to control a water treatment or distribution system. The decision support system collects data from multiple water system operators and analyses the data for a selected water system according to one or more rules or algorithms. The system returns data, optionally including alerts or predictions, to the system operator. Optionally, the decision support system uses machine learning applied to (i) historical data from a selected water system and/or (ii) data from other water systems to modify the rules or algorithms used to analyze current data from a selected water system. In some embodiments, the data collected includes microbial population data such as ATP data, optionally including derivatives of microbial population data; microbial speciation information; or, metagenomic data.

A UV reactor for disinfecting water. The UV reactor may include a cooling chamber in which heat from a UV source may be transferred to the water flowing through the UV reactor. The UV reactor may include driver circuitry operable to determine status information, such as health, of the UV source. The UV reactor may include a gas discharge path operable to substantially prevent accumulation of gas within a water treatment chamber.

Systems and methods for managing production and distribution of liquid water extracted from air. A system is provided that includes a plurality of local water generation units including a first local water generation unit and a second local water generation unit. The first and second water generation units each include a controller that is configured to control a production rate of liquid water extracted from the air, a local water collection unit, and a local transceiver. A principal water supply unit is in fluid communication with at least one of the local water collection units. The principal water supply unit is configured to store at least part of the liquid water extracted from the air and to maintain a principal water level at a reservoir of the principal water supply unit based on one or more operational parameters for water distribution.

A modular support system includes a central core and operation modules arranged radially around the central core. A first operation module is configured to receive water to be treated. A second operation module is disposed under the first operation module and is configured to receive the water and to perform a first type of water treatment. A third operation module is disposed under the second operation module and is configured to receive the water and to perform a second type of water treatment that is different from the first type of water treatment. A fourth operation module is disposed under the third operation module and is configured to receive and store the water for usage.

As an example embodiment, a system may detect water flow in a well water system and may responsively trigger a pump to inject a chlorinating substance into untreated water from the well. Further, the system may include a contact reservoir that allows the water and the chlorinating substance to combine. In this way, the chlorinating substance is drawn only when needed, but is given the opportunity to achieve time in solution with the untreated water. As a result, bacteria in untreated water may be dispatched, while other organic substances in the untreated water are given the opportunity to settle to the bottom of the contact reservoir. A static mixer may be used to mix the chlorinating substance and the untreated water prior to entering the contact reservoir and/or while in the contact reservoir.

A portable liquid filtration device includes a GPS tracking unit, a portable housing, an inlet configured to receive non-potable water, and an ozone chamber positioned within the portable housing. The ozone chamber is configured to generate an ozone gas from received air. The device also includes a filtration duct positioned within the portable housing and downstream from the inlet. The filtration duct includes at least one oxidation chamber configured to mix the received water with the ozone gas, and at least one ultraviolet (UV) chamber downstream from the at least one oxidation chamber and including a UV lamp positioned adjacent the water within the filtration duct. The device further includes an outlet positioned on the portable housing and downstream from the filtration duct. The filtration duct is operable to output at least 150 liters per hour of the received water from the outlet as potable water.

The present invention provides a method for comprehensive monitoring, analysis and maintenance of water and equipment in swimming pools, said method implemented by one or more processors operatively coupled to a non-transitory computer readable storage device, on which are stored modules of instruction code that when executed cause the one or more processors to perform: accumulating and monitoring data from elements including at least one of: sensors, actuators, and breakers in and around the vicinity of the swimming pools; accumulating non-sensory data from a plurality of sources at a local processing unit; propagating the data to an online remote server, applying machine learning or rule based algorithms at the online remote server configured to incorporate all the acquired data and obtain an optimal policy for pool maintenance by providing recommendations, control parameters, and providing an online interface to access said recommendation/control parameters for at least one of pool owners, pool servicemen, pool maintenance companies, pool vendors and pool retail dealers.
