| 20110284445 | DECK MOUNTED SOLAR CHLORINE GENERATOR AND METHOD - A deck mounted chlorine generator is shown that is preferably powered by use of a solar array panel. The cell plate housing can be supported by a plurality of swivel members that are locked into a position that conforms to the edge of a pool. The cell plate housing utilizes flow directing outlets to direct chlorine out of the housing. An opening such as a drawer is provided in the cell plate housing to permit salt to be poured into the housing around the electrodes to increase chlorine output. | 11-24-2011 |
| 20130098819 | ENHANCED RESIN REGENERATION - An oxygen and hydrogen emitter that is an electrolytic cell is disclosed. When the anode and cathode are separated by a critical distance, very small microbubbles and nanobubbles of oxygen and hydrogen are generated from aqueous solutions. The very small bubbles remain in suspension in the aqueous solution, forming a solution saturated in oxygen and hydrogen. A flow-through model for oxygenating and adding hydrogen bubbles in flowing water for water softeners is disclosed. Increasing the oxygen and hydrogen content of flowing water in residential and commercial water softeners to reduce sodium usage and increase resin regeneration efficiency with the use of an emitter is disclosed. | 04-25-2013 |
| 20150306527 | DIRECTED HYDROBURST SYSTEM FOR CLEANING FLAT SCREENS - A screen intake system has a body with an open end and a chamber. A flat screen is disposed at the open end of the body. To keep the screen clear of debris, an airburst system has pipes disposed in the chamber. The pipes dispose parallel to one another adjacent the flat screen, and each of the pipes has orifices in a side facing the flat screen. Directors are disposed along the backs of the pipes in a lattice, and each of the directors has a channel in which the pipe disposes. Compressed air released by valves from a tank dispersed from the pipe's orifices. Each of the directors directs the resulting water/airburst from the orifices toward the adjacent flat screen to clear it of debris. | 10-29-2015 |
| 20150328385 | COMBINATION OF A SINGLE-STATION REVERSE OSMOSIS DEVICE WITH A HEMODIALYSIS DEVICE - A combination of a single-station reverse-osmosis (RO) device comprising a hemodialysis device (HD device) is characterized in that a connection line is provided with a buffer chamber for permeate which serves on the one hand a faster permeate supply into the HD device and on the other hand a generation of a negative transmembrane pressure, and that upon request by the HD device the permeate flows either via the water inlet valve into the HD device or via a flushing valve of the HD device to an outlet. | 11-19-2015 |
| 20170233273 | Compressed Salt Block For A Liquid Treatment Apparatus | 08-17-2017 |
| 210191000 | With pump, injector or siphon | 4 |
| 20100276348 | DEVICE FOR GENERATION OF ION NETWORK FOR WATER TREATMENT IN TANKS - The invention concerns a device for generation of ion network for water treatment in tanks, especially for reduction of cloud and for stabilization of water surfaces, where the device is arranged on a floating body equipped with a drive for initiation of mutual motion of the floating body and water, whereas the floating body is equipped with an ejector and at least one source of electrolytically and/or photocatalytically treated water connected with an outlet ( | 11-04-2010 |
| 20120279912 | Chemical Mixing System and Method - A chemical component mixing apparatus for use with a fluid source in creation of a concentrated solution mixture is described. The mixing apparatus includes at least one mixing station. The mixing station includes an injector assembly, where the injector assembly includes at least one venturi chamber having at least one suction port in fluid communication with the at least one venturi chamber. The apparatus also includes at least one super concentrate chemical component housed within a chemical container, where the chemical container is fluidly connected by a first tube to the at least one venturi chamber via the at least one suction port, a receiving container fluidly connected to the injector assembly via a second tube, and a fluid source inlet introducing a fluid into the at least one mixing station, where the pressure within the at least one mixing station is less than 150 psi. The fluid passes through the at least one venturi chamber, thereby drawing the at least one super concentrate chemical component into the venturi chamber, and the concentrated solution mixture is dispensed from the injector assembly into the receiving container. | 11-08-2012 |
| 20140231328 | RAINWATER COLLECTION AND DISTRIBUTION DEVICE - The present invention is directed towards a rainwater collection and distribution device comprising at least one substantially elongate collector tank having an open upper free end and a closed lower free end, whereby the elongate collector tank is dimensioned to fit within a downpipe with its open upper free end exposed to rainwater entering the downpipe; the rainwater collection and distribution device further comprising a connection conduit having a lower open end adjacent the lower closed end of the elongate collector tank, and an upper free end connected to a pump; whereby, a delivery conduit is connected between the pump and a water storage tank. The advantage of providing the pump is that complete control may be exerted over the delivery of the collected rainwater to a water storage tank. Unlike prior art solution, where collected rainwater must be discarded through opening a motorised valve, the collected rainwater is held for immediate delivery, if required, to a water storage tank, by use of the pump. | 08-21-2014 |
| 20140353231 | METHODS FOR FUNCTIONAL ENHANCEMENT OF CERAMIC MEMBRANES AND SYSTEMS FOR SEPARATION OF AQUEOUS MIXTURES - The present application presents the development of a method for enhancing filtration capabilities of ceramic elements by chemically binding a hydrophilic compound throughout the porous structure of a ceramic element. An enhanced ceramic filter includes a ceramic element with chemically bound hydrophilic molecules. The enhanced ceramic filter is used in a system for the separation of non-polar compounds from aqueous mixtures. An aqueous mixture is passed through the enhanced ceramic filter, allowing water to permeate, and concentrate to exit the filter. | 12-04-2014 |
