Abstract:
The present invention relates to a reclamation and recycling process for graphene oxide, a scaffold comprising graphene oxide, a modular graphene oxide-based microbial fluid filter and a filter tool that allows the correct compression pressure of a modular filtration cartridge, and prevents internal leakage along the internal wall of the filter and thus provides correct sealing of the filter. Such modular graphene oxide-based microbial fluid filter does not require a sub-micrometer pore filtering medium, yet has a microbial filtration efficiency of up to 99.99% and the ability to filter particulates while still providing the filtration flow rates of current filters that do not employ a sub-micrometer pore filtering medium.
Abstract:
A smoke filter apparatus comprising a segmented conduit formed of a plurality of nesting sections and comprising one or more filters. The filters may comprise a preferred filter sequence, wherein the preferred filter sequence comprises a metal screen filter, a charcoal filter, and an acetate filter.
Abstract:
Virus and microbe-killing, self-sterilizing resistive heated air filters and methods of making and using same methods. The air filter is includes laser-induced graphene (LIG), a porous conductive graphene foam formed through photothermal conversion of a polyimide film (or another source or source of polymer or other LIG precursor material) by a laser source. The LIG in the air filter can capture particulates and bacteria. The bacteria cannot proliferate even when submerged in culture medium. Through a periodic Joule-heating mechanism, the filter easily reaches greater than 300° C. This destroys any microorganisms including bacteria, along with molecules that can cause adverse biological reactions and diseases such as viruses, pyrogens, allergens, exotoxins, endotoxins, teichoic acids, mycotoxins, nucleic acids, and prions

A method for processing raw coconut coir pith into fine particles having a size range of from 0.001 mm to 7 mm and the use of such fine particles directly or in formulated form in agricultural, industrial and commercial applications.
Abstract:
A portable outdoor water purifier includes a water absorption base, a filter element assembly, an electronic control assembly, and a filter container. The filter element assembly is installed in the filter container. The water absorption base is mounted to a lower end of the filter container. The water absorption base is connected with the filter element assembly. The electronic control assembly is mounted to an upper end of the filter container. The electronic control assembly includes a water outlet seat. Through the water absorption base and the filter element assembly, outdoor water can be filtered and sterilized layer by layer for a user to quickly get a large number of virus-free, bacteria-free, pollution-free safe drinking water in the wild, with high safety factor. This is an effective solution to the demand of drinking water for the outdoor sports enthusiasts.
Abstract:
The present invention provides a reverse osmosis filtration system without pressure tanks consisting of a filter element connecting member and external filter elements and having a raw water inlet, a pure water outlet and a wastewater outlet. In the reverse osmosis filtration system of the present invention, filter elements can be quickly and easily installed for avoiding leakage occurs during the installation or replacement of the filter elements, so that users can conveniently install or replace the filter elements by themselves and purposes of convenient operation and leakage prevention can be achieved. Meanwhile, water storage pressure tanks and pumps are omitted in the reverse osmosis filtration system of the present invention for reducing manufacturing costs and effectively avoiding secondary pollution.
Abstract:
Fluid distribution filters having spiral filter media and associated systems and methods are disclosed herein. In one embodiment, for example, a filter assembly can include a canister having a body portion positioned between a first opening and a second opening. The filter assembly can further include a filter media positioned in the body portion of the canister. The filter media can include at least one channel in fluid communication with the first and second openings. The channel can have a spiral-like shape and be configured to distribute incoming fluid across the filter media and move the fluid at a substantially equal velocity across the filter media.
Abstract:
Disclosed is a multiple separation filter including a microfiltration membrane, an active carbon-based filter and a ceramic filter stacked in order, wherein the active carbon-based filter is obtained by mixing active carbon with at least one selected from zeolite, gold, silver and a mixture thereof, treating the mixture with plasma gas of 60,000° C. to 70,000° C., and then quenching the mixture to −200° C. to −273° C. under vacuum, and the ceramic filter is obtained by quenching plasma gas generated by heating magnesium at 60,000° C. to 70,000° C. to −200° C. to −273° C. under vacuum. Disclosed also is antioxidant water obtained by using the multiple separation filter. The antioxidant water has a negative oxidation reduction potential.
