Home :: Processes :: Adsorption
In the adsorption process, contaminants in the aqueous stream break their bond with water molecules and chemically adhere to a filter media. In most systems this is accomplished by directing the water flow through pressure vessels containing the filter media at a rate that allows enough contact time for the adsorption to occur. Several medias have been developed to reduce a variety of contaminants such as arsenic and other heavy metals, fluoride, and dissolved organic chemicals like pesticides or petroleum products.
AdEdge Technologies GFO+adsorption media is the industry standard for arsenic reduction reducing up to 99% of total arsenic, including both arsenic (III) and arsenic (V). It is also effective in reducing other heavy metals such as lead, cadmium, chromium, antimony and molybdenum. This revolutionary iron-based granular adsorption media has 4 to 10 times the capacity of many adsorption medias. Adedge’s product is specifically designed for commercial and residential POE and small drinking water systems to meet the new EPA arsenic standard of 10 ppb. The media is discardable when spent and requires no chemicals or regeneration.
AD74, is an AdEdge adsorption media for reducing fluoride, which may be found naturally in some groundwater, added by municipalities, or in some industrial process waste streams. This media can be regenerated or used as a disposable one in smaller applications. It also has the capability to reduce some arsenic and other heavy metals.
