Ultra-D Submicron Depth Filtration Series

The Ultra D media consists of coated micro-glass fibres 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.

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 filters extend 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 a reduced pressure drop, saving energy. Opportunities for improving RO membrane performance include industrial and municipal wastewater, water re-use, municipal drinking water and desalination.

ULTRA-D SUBMICRON DETH FILTRATION

In addition to its submicron benefits, the Ultra D filter is also available in three other versions. With natural silver impregnated in the media to protect the filter surface from bacterial and fungal growth, killing pathogens on the filter surface. This makes the filter environmentally intelligent and allows the filter to be disposed of at any recycling centre or waste facility. With powdered activated carbon with an average particle size produces remarkably high dynamic adsorption*. With powered activated carbon and natural silver with the same benefits as above. *See contaminants removal list below.

APPLICATIONS FOR AND INDUSTRIES BENEFITTING FROM THE ULTRA-D FILTRATION PROCESS

Residential use where cost effective systems must be used and presence of pathogenic-laden water is of ongoing concern. Food and beverage industry for high purity water. Pharmaceutical industry for high purity water. Commercial pre-RO and ultra filtration treatment to sustain the life of the membranes. Greywater recycling for removal of pathogens. De-salination for pre filtration. Other high purity applications. Water re-cycling treatment for circuit board industry.

BENEFITS USING THE ULTRA-D FILTER CARTRIDGES VERSUS OTHER MEDIAS

Finer particle retention and filtration capacity (2 to 3-micron pore size comparable to a 0.02-micron size for virus removal.) Higher loading capacity (up to 25 times greater.) Greater efficiency in salt, brackish and fresh water. Wider pH operating window (4-9pH.) Very low pressure drop (approximately 2 psi.) lower cost of ownership. The capability of using one stand-alone filter system to achieve pathogens, heavy metal, taste and odour, chemical and organics removal or reduction (the carbon and silver version); for a broad range of applications including residential whole house point- of-entry and point-of-use for bottles and backpacks; unlimited commercial water filtration applications. The Ultra D filter series are available in 2-5 inch and 4.5 inch diameters (OD), and in 5 to 40 inch lengths.
