Silicon carbide flat sheet filtration membranes are supported on one piece manifold/end cap structures. Ends of a large number of the parallel flat plate membranes are fitted into elongated end cap slots that are part of a single molded manifold/end cap structure, such a structure being at each end of the series of membranes. In addition, a one piece external frame module can be provided to receive the gang of flat plate membranes with attached manifold/end caps. In the event of a damaged plate, the plate can be removed and replaced along with a special end cap repair section. This provides advantages over prior arrangements with individual end caps for each module or potting of the flat plates into a box or chamber.

The embodiments disclose an apparatus including at least one hypochlorous acid generator for producing purified hypochlorous acid from purified water and pure salt, a mixing tank container hypochlorous acid generator for processing the purified water and pure salt, a cap with vent configured to release gases created during an electrolysis operation, a water intake port to fill the mixing tank container with fill water automatically using an automatic system intake valve, a water drain port to drain liquid from the mixing tank container, an AC port to route external power circuits connections, at least one crossing double electrode module configured to provide ultraviolet light to purify water and perform electrolysis, an LCD control panel coupled to control buttons to display processing status and operation control settings, and a hypochlorous acid generator app on a user digital device to transmit hypochlorous acid generator control settings.

Modular Hg analysis devices and methods are described for use in mercury speciation protocols. Modules can be selected and removably connected to one another to specifically target mercury species in a sample so as to accurately determine the presence or quantity of different mercury species in a fluid sample. Modules can include reductants for reducing inorganic mercury to form elemental mercury and amalgamation agents to capture the elemental mercury. Modules can include filters for capture of particulates as well as capture agents, e.g., solid phase extraction agents, for capture of organic mercury species.

The invention is a modular, flexible, thermal, insulating, multilayered enclosure utilizing membrane distillation technology. The enclosure has a heat conducting layer, an insulation layer, and a layer of hydrophobic, polymeric hollow fiber membranes between the insulation layer and conductive layer. The enclosure is wrapped around a heat exhaust to absorb and transfer heat to the hollow fiber membranes to facilitate membrane distillation enabling production of potable water.

The filter system includes a feed hose (10) arranged along a permeate hose (20), wherein the feed hose (10) and the permeate hose (20) include a membrane (7) as the common wall section, and wherein the permeate hose (20) is closed at the front end and includes a permeate outlet (29) at the rear end. A fluid to be prepared flows in a pressurized state through the feed hose (10). At the end of the feed hose, a first fraction of the fluid flows through a retentate outlet (25) out of the feed hose (10). A further fraction of the fluid moves through pores of the membrane (7) into the permeate hose (20). This fraction flows through a permeate outlet (25) at the end of the permeate hose (20), separate from the retentate, and out of the filter system.

In an embodiment, a modular water filtration system includes a magazine and a base. The magazine includes a plurality of cartridge receptacles, a magazine input water valve, and a magazine output valve, where a first cartridge receptacle is coupled between the magazine input water valve and the magazine output valve. The base includes a first fitting configured to receive input water, a second fitting configured to provide drinking water, a base input water valve configured to be coupled to the magazine input water valve, a first solenoid valve having a water path coupled between the first fitting and the base input water valve, a base first valve configured to be coupled to the magazine output valve, and a first switch.

A water purifier filter and a water purifier comprising same, according to the present invention, comprises: a filter housing including an inlet and an outlet; a filter module which is provided inside the filter housing to purify the water having flowed in through the inlet and then supply same to the outlet, wherein the filter module comprises a first filter member formed as a hollow tube and a second filter member made of a material different from that of the first filter member.

A method for controlling the growth of blue algae in a basin relates to the field of the restoration and protection of the natural ecology on the earth's surface. An ecological water treatment system was constructed for the basin with microorganisms, plants, animals, fillers and the like as main elements by building a novel ecological slope protection at the land-lake ecozone along the banks of the basin and planting eucalyptus in the basin water and/or on the bank of the basin, thereby effectively realizing the efficient nitrogen and phosphorus removal from the basin, controlling the spread of blue algae and improving the environmental water quality.

Described are methods and devices for the treatment of fecal matter. A column reactor is used to smolder fecal matter to produce and a volatile components stream and smoldered media. The volatile components stream may be subject to catalysis to reduce the emission of noxious substances and/or generate heat energy. Also described is the use of a turntable for removing smoldered media from the column reactor.

An indicator for management of a filter cartridge for a filtering bottle, the bottle including a container with a neck, a filter cartridge and a cap with a coat. The indicator includes a first ring, a second ring arranged coaxially on the first ring, wherein the first and the second rings are rotatable relative to each other. One of the rings includes markings relating to the filter cartridge arranged around the ring and defining a time unit. The other ring includes an indicating element for indicating a selected marking relating to the filter cartridge by rotating one of the rings relative to the other. The indicator for management of the filter cartridge is also adapted to be mounted around the neck of the container of the filtering bottle under the coat of the cap. Furthermore, a filtering bottle and such an indicator for management of a filter cartridge and a set of a filtering bottle and such an indicator for management of a filter cartridge are described.
