Aqueous Solutions Global [ASG] manufactures a unique and superior oxidation product, AP Oxidation Media. The ASG, AP Oxidation Media is protected by US Patent. All ASG media products meet the ANSI Standard NSF 61: Drinking Water System Components – Health Effects.

 

What is oxidation and how does the ASG AP Oxidation media work?

An oxidant is a molecule, atom, or ion that loses electrons. The oxidized substance (which lost the electrons) increases in positive valence. Oxidation never occurs alone, but always occurs, with another substance, as part of the oxidation-reduction (redox) reaction. The reduced substance gains electrons and thereby, decreases in positive valance. The total number of electrons lost by one agent (reducer) to an oxidizing agent (oxidant) is the same total number of electrons gained by the substance. Oxidation results in an increase of positive valance. Examples of oxidation agents include oxygen, ozone, chlorine, peroxide, Bromine and ASG AP  Oxidation Media.

ASG AP Oxidation Media will outperform comparable oxidation agents because the ASG Oxidation Media has many more oxidation sites. AP  Oxidation Media rapidly and permanently changes the oxidation state of target analytes.

 

What is an example of oxidation utilizing AP Oxidation Media?

There are numerous technologies available to remove pentavalent Arsenic [As V] from aqueous streams. However, many of these methods are unable to remove trivalent Arsenic [As III], which is the more toxic form of Arsenic. When water containing Arsenic III, comes into direct contact with AP Oxidation Media, with a dwell time or empty bed contact time [EBCT] of 1.5 to 2 minutes, the Arsenic III is converted quickly and completely to its new valence state, Arsenic V. Arsenic in the pentavalent form can now be removed using common methods such as adsorption, ion exchange and reverse osmosis.

What is the chemistry and functionality of AP Oxidation Media?

Aqueous Solutions Global [ASG] manufactures AP  Oxidation Media, Al(IO4)3 using a proprietary process, combining Alumina Oxide with Sodium Meta-Periodate, along with other enabling chemistries.  AP Oxidation Media, is free of Sodium Oxide which is rinsed away in the manufacturing process, leaving only oxidation properties.

An oxidation reaction takes place in an aqueous stream when target analytes (contaminants) come in direct contact with the AP Oxidation Media granules. The reaction occurs rapidly, typically in 1.5 to 2 minutes of contact time. All ASG media, such as AP Oxidation, have exceptional oxidation kinetics and capacity properties.

 

Are there additional features of AP oxidation Media?

AP  Oxidation Media has selective adsorption capabilities and like many other oxidation products, has anti-microbial properties as well. Bacteria are killed on contact within seconds. Meta-Periodate, a form of Iodine, is an effective anti-microbial agent. When microbes, like bacteria, come into direct contact with AP Oxidization Media, the bacteria cell wall ruptures, killing the microbes.

There are no resulting objectionable tastes, color or odor. Unlike Chlorine, there are no waste streams or harmful by-products that could be introduced into the environment. No Chlorine/dechlorination steps are required.

Highly Alkaline or Highly Acidic fluids passing through the ASG AP Oxidation Media will be “buffered” toward a more neutral pH.

The ASG AP Oxidation Media will pass both TCLP and WET tests, for economically non-hazardous solid waste disposal. Unlike adsorption resins, AP Oxidation Media can be repurposed as a substitute for sand for making high strength concrete.

The easy to install and operate ASG AP  Oxidation Media has been used successfully in hundreds of field applications with complete customer satisfaction.

AM ADSORPTION MEDIA

AM Adsorption Media is a proprietary Aqueous Solutions Global media designed for rapid, high capacity removal of inorganics and metals; such as Arsenic and Fluoride from potable and process water streams. The designation of AM in the product name, is derived from the two functional components of the media: Alumina and Manganese. AM Adsorption Media is an activated alumina (AA) /Manganese complex, using a patented process developed by Aqueous Solutions Global. Chemical grafting begins by first binding an oxidizing agent to selected activated alumina in a slurry of de-ionized water and other enabling chemistries. We use a proprietary oxidant, which at the level employed, provides complete binding.

The resulting AM  Adsorption Media granules are free flowing and will remain stable indefinitely, in either a dry or wet slurry. Tests conducted by independent laboratories reveal no detectable levels of either Manganese or Aluminum that leached from the processed AM  Adsorption Media. The AM  Adsorption Media also passed the ANSI Standard NSF 61: Drinking Water System Components – Health Effects test.

Many hundreds of laboratory and field evaluations of the AM Complex Adsorption Media reveal significant advantages over other medias or technologies currently advocated by the EPA for the remediation of Fluoride and total Arsenic, either in the trivalent or pentavalent Arsenic form.  The capacity for Fluoride is many time greater than AA.

Compared to activated alumina, AM  Adsorption Media will:

  • Provide nearly 10x the contaminant removal capacity. Using a raw challenge water concentration of 100 ppb of either As III or As V, AM will process greater than 16,000 column volumes [CV]. Activated alumina will only process about 2,000 CV of As V and only 20 CV of As III.
  • Provide nearly 10x the rate of Arsenic adsorption. Optimal flow conditions for activated alumina are 0.2 CV/min. AM Complex Adsorption Media systems produce non-detect levels of Arsenic at 2+ CV/min at a 100 ppb of As III challenge level.
  • Work well at a pH range of 6.0 to 8.5. Activated alumina requires pH of 6.0 to 6.5 for optimal performance.
  • Provides a faster on-line time. During the Aqueous Solutions Global manufacturing process, the vast majority of troublesome “fines”, associated with activated alumina, are eliminated. A brief forward directional flow of product fluid is suggested to wash and remove any trace of color or fines, resulting in a clear-bright product. This forward wash will also aid in settling the AM  Adsorption Media bed. This brief washing step is normally all that is required to be on-line ready.

A. Compared to ion-exchange, AM  Adsorption Media will:

  • Not require large quantities of salt needed in the regeneration of ion-exchange resins.
  • Not require managing high concentrations of Arsenic contained in the aqueous brine discharge of ion-exchange resin systems.
  • Will permanently bind the metal contaminants, which permits the safe disposal of the spent media into a landfill as a non-hazardous material.

B.  Compared to granulated Ferric Hydroxide (GFH), AM  Adsorption Media will:

  • Not crumble and disintegrate during installation or use.
  • Remain a robust, rigid, high strength media even in high pressure or high flow conditions, which allows for simpler, more rapid installation.
  • Will not progressively compact, which causes loss of flow and pressure drop.
