Removing Pollutants from Water

Various industries need to remove trace pollutants from aqueous sources in an economical manner

VARIOUS TREATMENT TECHNOLOGIES

MATRIC 8

Bacterial Treatment

Anaerobic Bacteria Removal: uses naturally occurringmicrobes in specially developed mixtures, or cocktails, tochemically reduce and precipitate target compounds fromsolution. This system also is capable of breaking downtarget compounds into their harmless chemicalcomponents (e.g., turning nitrate into nitrogen gas).

AdvantagesLow Cost (Power and O&M)

High potential pollutant removalrates

DisadvantagesStart-up required for development ofmicroorganism populationChemical and/or environmental changes caninactivate the processSensitive to upset conditions

Wetlands Treatment

Wetlands: uses particular features of plant andmicrobial processes to remove contaminants in water,including selenium.

AdvantagesLow costs (power and O&M)Adaptable to any geometrical configurationRemoval of a wide range of aquatic contaminants

DisadvantagesLong residence timeSusceptible to toxic and/or environmental changesToxic bioaccumulation for wildlife

Reverse Osmosis Treatment

Reverse Osmosis: pressurized process to force a solutionthrough a membrane, retaining the solute on one side andallowing the pure solvent to pass to the other side.

AdvantagesEffective removal of a high percentage of contaminants

Less susceptible to chemical and/or environmental conditions (retains efficiency over a broad range of conditions)

DisadvantagesA concentrated waste stream produced that requires subsequent disposal

Pollutant removal required from waste stream

High costs (power and O&M)

Fouling significantly reduces unit effectivenessover time

Reactive Filtration

AdvantagesSimple chemical reactionRelative ease in the removal of selenium,

arsenic, mercury and aluminum concentrate for disposal

Short retention timeConstruction and O&M costs significantly

lower than other technologies

DisadvantagesTDS has to be considered

Sulfates are detrimental

Reactive Filtration: unpressurized, often passive processreact trace impurities with specific reactive media toremove them from the aqueous stream
