Introduction

Perfluorinated compounds (PFCs) are a newclass of persistent organic pollutants. Theyconsist of a hydrophobic perfluorinated carbontail and a hydrophilic ionic head. Due to theunique structure of fluoride-carbon bond, theypresent significant thermal and chemicalstability. As a result, there is

Only Catalytic Carbon (ZVI) coated with acationic surface modification canremove Halogenated Organic Compounds.

Not even one conventional biological treatmentof water or waste water is applicable so far.Filtration techniques such as nanofiltration andreverse osmosis have shown massivedestruction in the environment with membraneconcentrate and as well as adding massiveoverall management costs.

Watch Water® adsorption treatmenttechnologies including SuperOxy is an AdvancedOxidation Processes (AOPs), photolysis anduse of Zero Valent Iron (ZVI) activated carbonwith MGO surface is the solution for directdegradation of PFCs and removal of PFOA equalto 95% using sulfate radicals and photolysis ofregenerated concentrate. SuperOxy caneffectively degrade perfluorocarboxylic acids(PFCAs) to fluoride ions and carbon dioxide. Inrecent years Catalytic Carbon (ZVI) hasemerged as one of most innovative technologyfor the removal of most difficult environmentalpollutants through reduction regenerationmechanism. The high reactivity of catalyticcarbon is due to the high surface area and itsvery high negative (-) surface for cation’s. Forthis reason, Watch Water® has created a newstable adsorber by attaching stabilizedmolecules onto ZVI particles MgZVI/AC.

An adsorption process of Catalytic Carbon MGhas extremely high adsorption capacity of C2-C6-C8 fluorine- containing compounds and can beadsorbed without any morphological change.Therefore by the use of adsorption CatalyticCarbon MG; and desorption process usingSuperOxy all adsorbed substances can berecycled or destroyed using solar energy. Wateror wastewater containing C2-C6-C8 fluorine-containing compounds is passed through apressure vessel with the catalytic carbon MG toadsorb PFOA, PFHA & PFOS and the water atoutlet is without fluorine-containing compounds.

The Catalytic Carbon MG having the adsorbedfluorine-containing compounds can beregenerated up to 5 years so as to desorb theFluorine-Containing-Compounds.Catalytic Carbon MG features two mechanismsthat work rapidly and remove PFOA, PFOS andmany other per-fluorinated (PFAS) compoundsfrom contaminated water supplies. This isabsolutely a new process Catalytic Carbon MG+ SuperOxy to regenerate carbon’s. CatalyticCarbon MG can remove 97% of PFOA and PFOSfrom an initial concentration of as low as 0.5 ppbin only 4 to 5 minutes.

Regeneration

The Regeneration time may be generally from 45minutes to 1 hour

For ExampleBackwash --------→ 5 MinutesBrine Solution-----→ 30 minutesSlow Rinse --------→ 10 minutesFast Rinse --------→ 5 minutesTotal Time --------→ 50 minutes

Regeneration with SuperOxy means reactivationof adsorber and destruction of adsorbate withstrong Oxidation. Regeneration can be explainedas combination of Desorption and Activation ofadsorber with SuperOxy. Regeneration processcan be carried onsite and using SuperOxy anyAdsorber or any Activated Carbon can bereactivated for multiple uses. SuperOxy hassolved the problems of discarding spentadsorbents.

Residential and Commercial Water Treatment

Point – of – Use Water Treatment

The high capacity of our Catalytic Carbon MGadsorber makes it ideal for POU applicationsthat can remove PFOA and PFOS, pesticidessuch as atrazine and chlorpyrifos, organicsynthesis such as bisphenol (BPA), as well ashundreds of Pharmaceuticals compounds. CC-MG can be easily integrated into all majorcategories of POU water filters like faucetmounted, counter top, under the sink and tablepitcher products.

PFOS and PFOS can be removed by up to 99%using Catalytic Carbon MG.

The Mobility, Persistence and widespread use ofperfluoroalkyl and polyfluoroalkyl substances(PFAS) have resulted in all municipal andcommunity drinking water systems globally.PFAS were found in the drinking water of morethan 1.6 billion citizens in 70 countries and arecent analysis indicates that PFAS –contaminated drinking water is much morewidespread than previously reported. Thesechemicals are “All-over” and “Forever” aroundus. These toxic chemicals are contaminatingeverything from food and drinking water even theair around us.Catalytic Carbon MG can be used all type ofapplications like Municipal and Industrial

Drinking water treatment systems based onActivated carbons at residential and commercialapplications are unable to removemicropollutants and harmful perfluorinatedcompounds from the drinking water facilities.CC-MG adsorber offer an easy and cost-effective way to help bringing healthy and cleanwater to all residential and commercialapplications.

Per- and polyfluoroalkyl substances (PFASs) arerecalcitrant compounds that throughbioaccumulation can cause a several number ofAdverse Health Issues upon various exposurepathways. PFASs causes endocrine disruptionsand are potential carcinogens which will lead tobirth defects and obesity. These complicationshave led the Environment Protection Agency (EPA)to establish health advisory levels of 70 parts pertrillion (ppt). PFAS are man made chemicals thatare found highly toxic chemicals and used infirefighting foam, non-stick cookware and water-repellent clothing lurking in their water supply.When PFAS contaminates the drinking watersource, is it enough to just treat water thatpeople drink? Or do all countries and communitiesneed to do more to avoid and limit resident’sexposure?

Perfluorinated Carboxylic Acids (PFCAs) CnF (2n+1)CO2H

With Great Hydrophobic character

“The real fact is that, these compounds are sopersistent that if they are in the water in anycase, whatever the water is used for has thepotential to cause an exposure issue. We allknow if we feed this water to dairy farms, fishfarms then the milk, fishes and all the productsare contaminated too. Even were the soil beingcontaminated food is contaminated too.Watch Water® has a solution to treat PFAS –contaminated water with Catalytic Carbon MGand regenerate and deadsorbs the carbon withSuperOxy (SO). These SuperOxy system usesTitanium dioxide Powder mixed with Oxydes-P.This process breaks down the contaminant’sformidable molecular bonds while cleaning thewaste water and systematically destroying thehazardous compounds with Solar or UV energy.“SuperOxy (SO) oxidation is a simple, clean andmost effective method for destruction of PFASand other co-contaminants as a complementaryprocedure to other waste water treatmentprocesses.” We can break down and eliminatethese contaminants from Ground Water,Surface Water, Waste Water and Soil. TheseSuperOxy process systematically breaks downPFAS and transforming it from a toxic,hazardous material to a) Carbon dioxide b)Water c) fluoride.As Watch Water® is a leader in Oxidationtechnology, the Titansorb P (Titanium dioxidePowder) powders are providing themselves askey workhorses in the regeneration of adsorberprocess. Catalytic Carbon MG is showing greatresults even after plenty of regenerations.
