Description
Fine filter cartridge 20'', 5 µm, Big Blue is a sediment filter cartridge designed for fine particulate retention in water-treatment and laboratory process streams. With a stated pore size of 5 µm and a 20'' length in Big Blue format, it provides depth filtration for suspended solids and sediment. The unit is described as a Flow-Pro melt-blown sediment cartridge (FFK 5 micrometre filter cartridge), suited to applications where consistent fine filtration and cartridge-style housing compatibility are required. Supplied as a single piece, this filter candle supports routine maintenance of prefiltration stages ahead of reverse-osmosis, EDI, or polishing systems. The melt-blown construction is intended for sediment capture along the cartridge depth, helping protect downstream membranes and components from particulate load. Offered from manufacturer Evoqua Water Technologies, the cartridge fits Big Blue-style housings that accept 20'' fine-filter elements. It is classified under filter cartridges for laboratory and process water use and is selected where a 5 µm rating and extended 20'' length are specified for the installation.
This article is part of Filter cartridges & capsules, in Filtration.

Questions about Fine Filter cartridge 20'', 5µm Big Blue
What is this article?
Fine Filter cartridge 20'', 5µm Big Blue is the article on this page. Luminix Health distributes Evoqua Water Technologies for laboratory use. It sits in Filter cartridges & capsules, inside Filtration, in Lab consumables.
A cartridge or a capsule is a pleated filter for a larger volume than a syringe filter, often in a housing or as a disposable capsule. Pore size, membrane and the connection, hose barb or sanitary, are the specification. It is the filter of a transfer line, not of a single injection.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
