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.
Claims8
A filter compression spacer, said filter compression spacer comprising:
- a.) an exterior surface and an interior surface said interior surface defining an interior void comprising a top surface area and a bottom surface area;
- b.) a first plurality of stems protruding radially inwardly from said interior surface from 60% to 85% towards the center of said void, each said stem of said first plurality of stems having two opposed branches extending circumferentially outward from a respective said stem without intercepting an adjacent stem and without intercepting said interior surface, said two opposed branches being oriented concave inwardly, said stems covering a portion of said void's top surface area and bottom surface area.
