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 water treatment system includes an ozone generator combined with an electrolytic chlorine generator in a compact, efficient and serviceable assembly. The system may include a modular and replaceable ozone generator, which allows a damaged or non-functional ozone generator to be quickly and efficiently replaced. In order to protect the ozone generator from damage, a fail-safe drain valve assembly may also be provided which will expel backflowing pool water before it is allowed to backflow into the ozone generator. The water treatment system may further include an insulated electrolytic chlorine generator that mitigates or eliminates current leakage for efficient operation.

Abstract: An Air-Water-Food-Fabric-Space-Utility sanitizer (all in one) comprises a detachable blower chamber, a detachable UVC lamp holder, a detachable UVC lamp chamber, a detachable water chamber and a detachable lid. Said invention transforms to an air purifier, a chamber-style sanitizer, or a stand-style sanitizer when one or more chambers are detached. Germicidal lamps surround a target such as air, water, food (meats, plants), fabric (masks, towels), space, utility and soil to kill pests, parasites, insects and pathogenic spores. Said invention also develops seed germination. Water converts gas (MVOC) to liquid and arrests airborne contaminants. A blower drives them to water to enable the use of optimal dosage of UVC light. By either UVC-irradiating water or oxidizing water, pathogens are destroyed in the water chamber. Filters activate spore dispersal when disposed by burning. By not using potentially hazardous waste or an air outlet, pathogenic spores cannot reproduce or return to the environment.

Abstract: A water purifier structure includes a container assembly and a buffer unit mounted in the container assembly. The container assembly includes a housing and a cap unit. The housing has a first receiving section and a second receiving section. The second receiving section of the housing is provided with a retaining portion. The buffer unit is mounted in the second receiving section of the housing and includes a positioning ring secured in the retaining portion of the housing, and a cushioning member mounted in the positioning ring. The cushioning member is elastically movable in the positioning ring. When the cushioning member is compressed by a force, the cushioning member is contracted and elastically deformed toward the second receiving section of the housing, to form a buffering force.

Abstract: Devices and methods associated with these devices for significantly improving the efficiency of an existing or new filter having a granular media filter bed. The methods and devices are designed to increase the height and hence overall volume of the filter bed to allow for longer filtration runs between washing or cleaning cycles of the granular media filter bed. One embodiment includes a multi-wash trough adapter that upon removal of an existing deep wash trough connects two shallow wash troughs or two shallow wash trough channels to an existing wash trough opening formed in a wall of a filter compartment. The shallow members have a height significantly less than the height of the existing deep wash trough, e.g., one third to one half of the height of the existing deep wash trough allowing the volume of the granular media filter bed to be significantly increased.

Abstract: A control valve for a reverse osmosis water purifying system provides a feed water port, a squeeze water port, a drain port, and a product water connection, each of which open into a bore. A first, second, and third O-rings are located in the bore successively between the feed water port, the squeeze water port, the drain port, and the product water connection. A control piston is moveably located in the bore of the housing. The control piston includes a vent/drain well in which a side is chamfered and at least one recess disposed around an end of the control piston. The vent/drain well provides a fluid passage between the squeeze water port and the drain port when the vent/drain well passes over the second O-ring. The fluid passage includes an opening formed between the second O-ring and the chamfered side of the vent/drain well, where the size of the opening is responsive to the position of the control piston.
