A method for filtering one or more of run-off fluid, chemical spills and facility discharge, the method including: storing a first portion of the one or more of run-off fluid, chemical spills and facility discharge in a first compartment; discharging additional fluid from an overflow in the first compartment when a volume capacity of the first compartment is full; in a second compartment in fluid communication with the first compartment, filtering the one or more of run-off fluid, chemical spills and facility discharge stored in the first compartment that is not discharged through the overflow, and discharging filtered fluid from the second compartment.

Embodiments of the present disclosure could generally provide a relatively easily squeezable beverage bottle that allows control of the flow rate of the liquid being dispensed to the user. The bottle could provide sufficient radial rigidity—or resistance to squeezing—to return to its original shape (or “bounce back”) at a suitable rate without experiencing permanent deformation or denting and to withstand the rigors of filling, shipping, transporting, dispensing, etc. The present disclosure generally provides a beverage bottle filtering system that provides adequate filtering of water taken from the bottle at a suitable rate. In one embodiment, the present disclosure could include a support system to adequately secure the filter media within a filter housing while ensuring a sufficient compression fit and seal of filter media within filter system to eliminate “bypass flow” (i.e., water that might leak past filter system) and prevent consumption of unfiltered water.

The present invention relates to an adsorption filter including activated carbon and a fibrillated fibrous binder, in which the activated carbon has a 0% particle diameter (D0) of 10 μm or more in a volume-based cumulative particle-size distribution and has a 50% particle diameter (D50) of 90 to 200 μm in the volume-based cumulative particle-size distribution; the fibrillated fibrous binder has a CSF value of 10 to 150 mL; and the adsorption filter includes 4 to 8 parts by mass of the fibrillated fibrous binder relative to 100 parts by mass of the activated carbon.

A water purifying apparatus including a head having a water inlet portion and a water outlet portion; a shaft provided in the head and rotatably mounted between the water inlet portion and the water outlet portion; a bypass flow path passing through a circumference of the shaft, and communicating the water inlet portion with the water outlet portion according to rotation of the shaft; a filter detachably mounted to the head, and having a filter inserting portion in which the shaft is inserted when being mounted on the head; and a filtering flow path in which an inlet port and an outlet port are formed on the circumference of the shaft in a direction intersecting the bypass flow path, and communicated between the filter, the water inlet portion and the water outlet portion with each other according to the rotation of the shaft.

An aquarium filter and a method of indicating reduced flow through the filter. The aquarium filter includes a first chamber, a second chamber, and a filter cartridge separating the first chamber and the second chamber. A first flow path is defined through the filter cartridge separating the first chamber and the second chamber. The aquarium filter also includes spillway defining a second flow path and an indicator positioned in the second flow path.

A cartridge for use in a water purification apparatus and a water purification method for maintaining a water quality supply are provided. The cartridge comprises an elongated tubular body having first and second ends comprising a fluid inlet and a fluid outlet, and an internal chamber extending between the first and second end. The first end includes an end cap having a first opening in fluid communication with the body. A disinfectant material is disposed in the internal chamber of the body. Filters are disposed in the elongated tubular body adjacent to the first opening and adjacent the second end of the elongated tubular body and are in fluid communication with the internal chamber and the fluid outlet. The second end of the elongated tubular body comprising an exterior surface having a tapered portion and a linear portion adjacent to the tapered portion.

A novel magnesium-based alloy is described. The alloy is particularly suitable for the construction of electrodes, especially anodes, that can be used for an electrochemical process, such as the synthesis of struvite. The magnesium-based alloy is an AZXY alloy in which A is aluminium and Z is zinc, X represents the content, expressed in wt. %, of the first element, and Y the content, expressed in wt. %, of the second element. The AZXY alloy according to the invention has 2%≤X≤4% and 0.5%≤Y≤2%, and an iron (Fe) content of less than 0.005%, and preferably less than 0.003%. The anodes constituted by this novel alloy have a much slower corrosion speed and improved performances compared to existing anodes. An electrode cartridge comprising said alloy and suitable for being inserted into an electrolytic reactor so as to form, once assembled, an electrocoagulation unit, is also described.

A two-stage filtering system including a first and second filter container. The first filter container has a first filter assembly with a foam filter sleeve enveloping a fluid intake device, a connected valve, and transfer tubing. The second filter includes a pump connected to a spout, a second stage splashguard strainer, a second stage cup filter, and a second filter assembly. The second filter assembly includes at least one main filter comprising at least one carbon body filter enveloping a filter chamber, and exit tubing. The first filter container is structured to stack on top of the second filter container and the transfer tubing is structured to transfer first stage filtered fluid to the second filter container. The pump is structured to draw second stage filtered fluid from the second container through the exit tubing and expel the second stage filtered fluid out the spout to provide purified water.

Systems and apparatus for a fluid filtration device may include a filter housing having openings disposed along a sidewall of the filter housing and a check valve extending outwardly from a first end of the filter housing. The fluid filtration device may include a riser coupled to a second end of the filter housing and a filter cap coupled to a second end of the riser. The filter cap may have an opening fluidly linked to the riser and the filter housing and be configured to selectively attach the fluid filtration device to a container for holding fluids such as a three to six gallon refillable water container.

Some embodiments of the invention provide a reverse osmosis water filtration system including a housing, a pre-filter cartridge, a reverse osmosis cartridge, and a post treatment cartridge. A medial water line transports a first portion of pretreated water from the pre-filter cartridge to the reverse osmosis cartridge. An unfiltered water line includes a flow restrictor and blend valve. The unfiltered water line is fluidly coupled between the medial water line and a blend water line. The blend water line receives filtered water at a first flowrate from the reverse osmosis cartridge and unfiltered water at a second flowrate from the blend valve. The first flowrate and the second flowrate are substantially equal to produce a consistent total dissolved solids value.
