A system for limiting the flow from a dispensing valve when a dispensing cartridge is replaced with the system including a dispenser cartridge with a cam and a water socket with a flow limiter therein that is activeable in response to the position of the dispenser cartridge in the dispensing valve and operable in response to an upstream fluid pressure in the dispensing valve.

The present invention relates to an electrode for electrochlorination processes, optionally operable under polarity reversal conditions, comprising an active layer provided with a doped Ru—Ti catalytic composition.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

A device is provided for disinfecting water of a swimming pool, which includes an inlet for water from the swimming pool and an outlet for the water, an ozonation device, and a mixing section for ozone-containing water, wherein the ozonation device includes at least one UV light source for generating ozone, and an admixing unit for admixing the ozone to the water of the inlet, and the mixing section comprises a housing connected to the inlet, wherein the UV light source is arranged within the housing to emit UV light into the housing interior. The housing has deflecting surfaces for water protruding into the housing interior, which ensure a meandering flow within the housing. The device enables improved disinfection and can be designed to be more space-saving and visually appealing than conventional devices.

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.

There is described a water monitoring device for monitoring a body of water. The body of water comprises a main body of water and a water inlet and/or water outlet. The water monitoring device comprises a sensor operable to generate data in relation to a property of the body of water, an attachment member operable to removably arrange the device in a substantially stationary position adjacent to the water inlet and/or water outlet of the body of water; and a communication member operable to transmit the data relating to a property of the body of water to a remote device. Also described is a water monitoring apparatus and a method of monitoring a body of water.

A managed water system can include a first body of water contained in a vessel. The managed water system can also include at least one sensor device that measures at least one parameter associated with the first body of water. The managed water system can further include a circulation system that circulates the body of water relative to the vessel. The managed water system can also include a controller communicably coupled to the at least one sensor device and the circulation system. The controller can control the circulation system, and receive measurements of the at least one parameter made by the at least one sensor device. The controller can also evaluate the measurements using multiple algorithms, and communicate a result of evaluating the measurements.

A water treatment insert for a pool skimmer system includes a chemical treatment portion separated from a mechanical filtration portion. The treatment device includes an upper portion and a lower portion. The upper section can include a vertical wall or walls, which should be substantially watertight so that substantially all the water entering the pool skimmer flows through the upper portion, and then into the lower section. The entire device is preferably received in the filter basket receiving section of a conventional pool skimmer, in place of the conventional filter basket. One of the upper and lower sections provides mechanical filtration and the other chemical treatment, to enhance the water treatment function of the skimmer.

A pool cleaning system for cleaning debris from a submerged surface of a swimming pool includes a self-propelled pool cleaner having rotatably-mounted supports for supporting and guiding the cleaner on the pool surface; an electric motor for enabling the rotation of the rotatably-mounted supports on the pool surface; at least one camera to capture imagery of the pool surface; a controller, in electronic communication with the at least one camera, to determine a cleanliness characteristic of the pool surface on which the cleaner has passed based on the camera imagery and generate a control signal to direct movement of the cleaner based on the cleanliness characteristic of the pool surface, and a portable electronic device configured to present a graphic on a display, the graphic depicting the submerged surface of the pool and those portions of the surface that remain uncleaned as the cleaner traverses the pool surface.
