Water
Our activated carbon technology provides the best solution for a variety of water purification applications
Many industrial plants and municipal agencies use our activated carbon products in their water filtration systems
Activated carbon is an efficient and cost-effective solution for removing a wide range of contaminants from industrial and municipal wastewater, contaminated ground and groundwater.
The U.S. Environmental Protection Agency (EPA) considers adsorption by activated carbon to be the best available technology for the removal of many contaminants in surface water. Activated carbon aids in the removal of:
- Compounds that cause unwanted taste, odor or color
- Organic materials from decaying plants and other naturally-occurring contaminants
- Disinfection byproducts (DBPs) linked to chlorine and alternative disinfectants
- Algal toxins and cyanotoxins, such as microcystin-LR, cylindrospermopsin and anatoxin-A
- Endocrine-disrupting compounds that can adversely affect hormonal systems
- Pharmaceutical and personal care products (PPCPs) contamination
- PFOS/PFOA
- Pesticides
- Heavy metals
Different types of activated carbon are suited for various specialized applications
-
Granulated activated carbon dechlorinates water, adsorbs organic material and produces a chemical-reducing environment
-
Granulated activated carbon impregnated with silver salts inhibits the growth of bacteria
-
Catalytic activated carbon removes chloramines from drinking water
-
Pelletized (or extruded) activated carbon effectively dechlorinates and removes chemicals
-
Powdered activated carbon is used to eliminate trace synthetic chemicals and taste and odor causing chemicals, and for chemical spills or algal blooms
Process Water Treatment
Process water, used as part of industrial processing, includes both potable water, such as that added to juice drinks and consumed, and water such as wash water that is discarded or recycled. Our activated carbon is available in various forms, sizes, and impregnations to best meet many different process water needs.
Wastewater Treatment
Waste water includes highly-contaminated water from industrial processing, agricultural chemical use and landfill leachate as well as residential runoff. Wastewater treatment plants must purify the water to acceptable limits before releasing it into lakes, rivers or oceans.
We offer a variety of activated carbon formulations and equipment that target specific contaminants in many different proportions in wastewater including:
- Dissolved organic materials and micropollutants
- Heavy metals
- Hydrocarbons
- Pesticides
- Solvents
- Chlorinated hydrocarbons
Drinking Water Treatment
Activated carbon adsorption is regarded as one of the best and most common treatment methods for removing impurities from drinking water both at municipal treatment works and in home filter systems.
Granular activated carbon can be used in a filter bed or media through which water passes or powdered activated carbon can be fed into the treatment train and removed along with other solids present from the water treatment.
PFOA and PFOS
Scientific research has shown the effectiveness of granular activated carbon filtration systems in removing PFOA and PFOS contaminants from municipal drinking water.
Perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) have been accumulating in the environment for years. These perfluorinated compounds are also known as PFCs. The negative impact on human health from PFOA and PFOS is becoming a major concern of municipal drinking water providers.
Extremely resistant to degradation and repelling both water and oil, perfluorinated chemicals are used in:
- surfactant in fire-fighting foam
- emulsifier in floor polish
- mist suppressant for metal plating baths
- surfactant for etching acids for circuit boards
- pesticide for insect bait traps
- antistatic agent in photographic paper
- waterproof casts and wound dressings
- non-stick cooking surfaces
- soil and water repellent for carpet, upholstery, apparel
- oil and water repellent for plates food containers, cartons
Our carbon is used for numerous other water applications such as the manufacture of filter cartridges and reverse osmosis systems and in the production of highly-purified water for dialysis treatment.
