United Filters International announces its newest line of filters, The ULTRA-D Submicron Depth Filtration Series, which are manufactured using a proprietary, patented, electroadsorptive media technology, capable of removing submicron pathogens and inorganic contaminants through electro-adhesion and ion exchange. This technology makes it possible for a nonwoven media to produce filtration efficiency comparable to ultra membrane filtration but at very low pressure drop, with high flow rates and high loading capacity working equally well in fresh, brackish or salt waters.
The ULTRA-D media consists of coated micro-glass fibers produced using a wet laid nonwoven manufacturing technology. The base media is laminated between layers of spun-bond to provide both strength and pleat support. The media in the ULTRA-D filter is NSF 61-approved (Drinking Water System Components - Health Effects), and USP Class VI testing and endotoxin testing.
This media has been specifically engineered to have an average pore size of 2 microns and a mean flow pore of 0.7 microns. This allows the naturally occurring charge field to affect the total volume of the individual pores, as well as virtually the entire void volume of the filter media itself.
The media in these cartridges efficiently retain inorganic and organic particulates, cell debris, endotoxins, virus, proteins, many colloids, bacteria and inorganic submicron particulates. Contaminants are removed by being exposed to a torturous path through the media, depth and the powerful electropositive charge.
With the ability to remove membrane biofoulants such as organic acids, bacteria and cellular debris the ULTRA-D is an effective pre-filter to protect reverse osmosis membranes from biofouling. By reducing membrane biofouling, the ULTRA-D filter extends the performance and life of RO membranes by increasing the time between clean-in-place treatment and reduces the volume of reject water. Energy savings are also gained because clean membranes operate at reduced pressure drop, saving energy. Opportunities for improving RO membrane performance include industrial and municipal wastewater, water re-use, municipal drinking water and desalination.
