Problems solved by technology

However, these systems are expensive and cannot always be converted to be suitable for handling small quantities of gas, vapor or liquid (e.g. for a single user), as well as large quantities of substances (enough for a small village or community)
In addition, unclean storage facilities may contaminate water after previous decontamination

Embodiment 1

[0093] The ability of a fluid filtration system 600, which represents an embodiment of the present invention, to remove contaminants from an unpurified fluid was tested (see Image 6 ). Specifically, raw water is introduced into the inflow opening 601 of the system and communicated with Iodinated resin column 602 (approximately 5.5 mL) contacts, then flows through Nano-alumina fiber material 604 and dispensed through effluent opening 605. at position 603 with post-contact and at position 605 with the The material is tested for contamination after exposure. The flow through the system was 20 mL / min upstream. The test results are shown in Tables 1 and 2, where no detectable spread of MS2 or E. coli contamination occurred. SP1 represents the test at position 603 and SP2 represents the test at position 605 .

Embodiment 2

[0101] In an independent test using a separate Argonide filter, transmission of both MS2 and E. coli occurred after approximately 2.75 liters of water passed through a single filter unit. The results of individual Argonide filter tests are shown in Tables 3 and 4.

Abstract

The present disclosure generally relates to filter media compositions, apparatuses and systems for removing contaminants from fluids, as well as methods of using the same. In certain aspects the filter media comprises on or more halogenated resins (103) and one or more contaminant sorbent media (102, 104, 105, 106). The filter media of the present disclosure may be self-contained in a single unit or certain components may be housed in separate units acting in parallel or in series.
