Ion Exchange Technology

Ion exchange (IX) is a method of removing undesirable metallic salt ions dissolved in an aqueous stream by exchanging them with other ions attached to a media, such as a synthetic resin.  This  reversible chemical process occurs because ions have differing affinities for the resin and will replace those ions with less affinity or attraction as they flow over the media.  The ions that are most often used as the exchange ions are sodium and chloride.  Some of the ions that may be removed are calcium, magnesium, iron, uranium, nitrate, bicarbonate, carbonate, sulfate, and hydroxide.  Eventually, the resin will be saturated with the undesirable ions.  Depending on the application, the resin may be regenerated on site, regenerated at a central regeneration facility, or be replaced and disposed.  Water softeners use ion exchange to remove the hardness ions, such as calcium and magnesium, and replace them with sodium or potassium ions to make the product water less likely to form scale on pipes, appliances, and fixtures.
AdEdge Technologies has systems for uranium reduction using AD92 IX resin.  This resin has a very high capacity for uranium removal and is not as susceptible to organic fouling as other resins.  It is easily and effectively regenerated with sodium chloride on site which provides a cost-effective way to extend the effective life of the media, reducing operating costs. Frequently Asked Questions: Uranium Removal
Nitrate removal systems using AD IX are also available from AdEdge for drinking water systems or industrial waste streams that need to reduce the nitrate level to comply with EPA standards.  This resin is designed specifically for removal of nitrate ions and is regenerated with sodium chloride on site to minimize costs.

Adsorption Process

Water Treatment

Adedge Technologies, Water Treatment Systems
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’ Bayoxide®E33 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 Bayoxide ®E33 media is discardable when spent and requires no chemicals or regeneration. It has become the premier product of choice for commercial and drinking water treatment systems for reliable, cost-effective, proven reduction of arsenic.
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.

Oxidation Filtration

Oxidation/filtration refers to precipitative processes that are designed to remove naturally occurring iron, manganese, and sulfides from water. The processes involve the oxidation of the soluble forms of these contaminants to their insoluble forms and then removal by filtration of the precipitated particles.
Arsenic may be removed with the iron in some cases. Arsenic can be removed via two primary mechanisms: adsorption and co-precipitation. In groundwater containing both iron and arsenic, they are usually found in their reduced form. For optimum arsenic removal, a chemical oxidant such as sodium hypochlorite is often needed. Oxidized arsenic then adsorbs onto the iron hydroxide particles that are ultimately filtered out of solution. The arsenic removal efficiency is strongly dependent on the initial iron and arsenic concentrations.
The AdEdge Technologies oxidation/ filtration medias have high catalytic and oxidation activity, superior handling properties and stability, NSF 61 certification, require no permanganate or coagulation addition and low capital and operating costs compared to other alternatives due to the smaller system footprints. We have over 300 public water system installations and over 3,000 residential installations, more than any company in the U.S.

Water Treatment system for Uranium a Success in Village of Marshfield, Vermont

Following a very successful pilot test, AdEdge Technologies Inc. (AdEdge) was selected in 2007 by the Village of Marshfield, VT and the site’s engineer, Forcier Aldrich & Associates (FA&A), to supply and install a full scale uranium treatment system using its AD92 regenerative Ion Exchange (IX) Technology. Given the high naturally occurring uranium of 76 ug/L (nearly 3X the acceptable level), the municipal system had not utilized the two supply wells for several years. Bottled water was being provided to residents in the interim awaiting a solution. The affected wells serve a portion of the town and can produce up to 80 gpm with an expected average daily demand of 28,500 gallons per day. AdEdge was contracted to fabricate and install the treatment system by FA&A and the Village. The AdEdge team prepared the design documents to install a twin vessel parallel treatment system to reduce the high uranium levels to below MCLs. Both regenerative and throw away options were explored with the conclusion that the regenerative AD92 IX approach was the preferred and most cost-effective option for this site.

Designed to provide high efficiency removal of naturally-occurring uranium from groundwater supplies, the packaged, pre-engineered AdEdge AD92 system featured a twin vessel configuration flowing 160 gpm in parallel or 80 gpm per vessel. The system came complete with a manual regeneration/brine system to regenerate the IX resin periodically on demand. The complete system was packaged and delivered for site installation in July of 2007. AD92 IX media is a specialty strong base anion resin with high capacity for uranium removal. It provides superior removal efficiency for uranium and greater resistance to organic fouling than other media. The negatively charged uranium species binds to the anion resin as it passes through the bed and is periodically regenerated with salt brine solution periodically as the resin reaches a certain loading level. The system was permitted by the Vermont Water Supply Division and utilizes a local discharge permit for the periodic wastewater.

The system was placed into full time operation in early July, 2007 processing 80 gpm through the system. Initial results reported by the site’s State Certified Laboratory and reported to the State of Vermont Water Supply Division show excellent uranium reduction from 75 ug/L of uranium to below 2 ug/L (non-detectable) in the treated water. The system will be monitored regularly according to the terms of the operating permit.
