Abstract: Portable water conditioning systems include a water conditioner having a plurality of conditioning stages including, in a direction of flow of the water through the water conditioner, a reverse osmosis stage having a reverse osmosis membrane, and a deionizing stage. A first sensor is configured to detect a first condition of the water before the reverse osmosis stage and a second sensor configured to detect a second condition of the water after the reverse osmosis stage. The conditions each include (i) a level of total dissolved solids of the water and (ii) temperature of the water. A controller is in communication with the sensors and configured to determine of a percent of dissolved solids that are rejected by the reverse osmosis membrane based on the conditions when backpressure on the reverse osmosis stage is at a known state.

Abstract: 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.

Abstract: Extendable cleaning tools are described. The tools include a plurality of pole elements, wherein the plurality of pole elements include an innermost pole element and an outermost pole element, wherein the innermost pole element is moveable relative to the outermost pole element in an axial direction and the innermost pole element and the outermost pole element are not rotatable relative to each other, a clamp arranged at an end of the outermost pole element and configured to selectively engage with a pole element of the plurality of pole elements arranged within the outermost pole element, and a working head assembly attached to an end of the innermost pole element.

Abstract: A portable water conditioning system is provided that includes an incoming water inlet; a reverse osmosis stage in fluid communication with the incoming water inlet, the reverse osmosis stage having a permeate outlet and a concentrate outlet; a diversion device having a diversion valve, the diversion valve placing the concentrate outlet in fluid communication with a waste water outlet; a deionizing stage in fluid communication with a pure water outlet; a bypass valve configured to selectively place the permeate outlet in fluid communication with one or more of the waste water outlet, the deionizing stage, and the pure water outlet; and a controller configured to control the diversion device and the bypass valve to provide water at the pure water outlet of a desired condition.

Abstract: Water conditioning systems are shown and described. The water conditioning systems include a water conditioner having a plurality of conditioning stages along a flow path between an inlet and an outlet that are configured to condition water. The plurality of conditioning stages include a pre-filter stage, a feed pump, a reverse osmosis stage, and a post-filter stage. A pure water valve is arranged between the feed pump and the reverse osmosis stage and a boost valve is arranged between the feed pump and the outlet. The pure water valve is configured to selectively allow water to flow from the feed pump, through the reverse osmosis stage and the post-filter stage, prior to exiting through the outlet, and the boost valve is configured to selectively allow water to flow from the boost pump directly to the outlet and bypassing the reverse osmosis stage and the post-filter.

Abstract: Modular pure water systems are provided that have a tank and a cover assembly, wherein the tank and cover assembly are configured to removably receive therebetween one or more expansion tubes in a fluid tight manner to allow for selective volume expansion of the pure water system. Also provided are purification media bags for pure water systems that have a shape, construction, and/or material that mitigates the flow of water between the outer wall of the bag and an inner wall of the pure water systems.
