A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter medium is positioned within the filter chamber, each end of the filter medium being enclosed by an endcap formed from a resilient material, such as molded silicone or a thermoplastic elastomer. The endcaps slide on the ends of the filter media with no need for adhesive and form a fluid seal with both the filter media and the filter housing once installed. One or more fluid bypass channels may be defined by the filter housing or in the endcaps to allow water to flow as desired within the filter chamber. The resulting filter requires fewer components and less assembly time while improving filtration performance and reliability.

Methods of treating a fluid mixture include performing a first treatment on the mixture with electrochemically produced ions to separate an aqueous phase and a hydrophobic phase and performing a second electrochemical treatment on the separated aqueous phase to thereby remove aqueous contaminants from the aqueous phase wherein substantially laminar flow of fluid occurs between electrodes in the second electrochemical treatment.

A water purification system provides clean water for the consumption by livestock by using a continuously recirculating water loop. Optionally, a circulating pump moves the water within the water loop in a flow direction. A water supply inlet is fluidically connected to the water loop to provide additional water. A particle filter system (or systems) is fluidically connected in series and removes dissolved solids or particulates within the water. An ozone purification system and/or with the addition of other antimicrobial or purification agents is fluidically connected in parallel to a portion of the continuously recirculating feedback monitored and control water loop. The ozone purification system is disposed downstream of the particle filter system and RO (or similar) system in relation to the flow direction. A feeding station is connected in series with the continuously recirculating water loop disposed downstream of the ozone purification system in relation to the flow direction.

The present invention pertains to a process for treating waste water from mining. The process involves contacting the mining waste water with an emulsion of a nano scale compound comprising iron, magnesium, or both. Mixing results in a substantially foam-like layer at the surface of the mixture which may be further oxidized to form treated water.

Highly mesoporous activated carbon products are disclosed with mesoporosities characterized by mesopore volumes of 0.7 to 1.0 cubic centimeters per gram or greater. Also disclosed are activated carbon products characterized by a Molasses Number of about 500 to 1000 or greater. Also disclosed are activated carbon products characterized by a Tannin Value of about 100 to 35 or less. The activated carbon products may be further characterized by total pore volumes of at least 0.85 cubic centimeters per gram and BET surface areas of at least about 800 square meters per gram. The activated carbon product may be derived from a renewable feedstock.

This invention relates, generally, to the collection of water. More specifically, the invention relates to an atmospheric water generator, to a condensation arrangement for an atmospheric water generator, and to a process for extracting water from air. The generator disclosed herein comprises a coolant chilling unit, a condensation arrangement, and a water holding and/or filtration arrangement which cooperate to extract water from air and store and/or filter the same for use.

A composite filtration material is provided as well as a method for preparing the same. A filter is also provided that is fabricated with the presently disclosed composite filtration material. In various aspects, the provided composite filtration material may include activated carbon doped with silver and/or iron oxide. A one-step thermal decomposition process is provided that may be employed to prepare the provided composite filtration materials. The one-step thermal decomposition process may include dissolving one or more precursors in water, spraying the dissolved one or more precursors onto activated carbon, and heating the activated carbon saturated with the one or more precursors for a predetermined amount of time. The inventors have found that the provided composite filtration materials are more effective (e.g., higher removal of pollutants) and have a longer service life as compared to typical activated carbon filtration materials.

A water purification apparatus includes a water intake configured to receive water to the water purification apparatus, a filter part including a plurality of filters configured to filter the water and generate purified water, a water outlet including a plurality of water outlet ports configured to discharge the purified water, and one or more pipes that define a water purification path configured to guide the water from the water intake through at least one of the plurality of filters to thereby provide the purified water to at least one of the plurality of water outlet ports.

The present application relates to a novel method for reductive degradation of perfluoroalkyl-containing compounds, such as perfluoroalkyl sulfonates, by activated carbon (AC) supported zero valent iron-nickle nanoparticles (nNi.sup.0Fe.sup.0).

A method for mitigating microbe buildup within a potable water supply system including: cleaning of the water supply system; acquiring data including at least water conditions at multiple points within the potable water supply system; a control system adjusting local water conditions within the potable water supply system; a bacteria monitor assessing water within the potable water system to determine at least levels of bacteria within the potable water system; and applying an antimicrobial condition to water within the potable water system.
