Water
Our activated carbon technology offers optimal solutions for a diverse range of water purification applications.
Our activated carbon products are utilized in water filtration systems by numerous industrial plants and municipal agencies.
Activated carbon is a highly efficient and cost-effective method for eliminating a broad range of contaminants from industrial and municipal wastewater, as well as from contaminated ground and groundwater.
The U.S. Environmental Protection Agency (EPA) deems activated carbon adsorption as the most effective technology available for removing many contaminants from surface water. Activated carbon helps to remove:
- Compounds causing undesirable taste, odor, or color
- Organic materials from decaying plants and other natural sources
- Disinfection byproducts (DBPs) related to chlorine and other disinfectants
- Algal toxins and cyanotoxins, including microcystin-LR, cylindrospermopsin, and anatoxin-A
- Endocrine-disrupting compounds that can affect hormonal systems
- Contaminants from pharmaceutical and personal care products (PPCPs)
- PFOS/PFOA
- Pesticides
- Heavy metals
Different types of activated carbon are tailored for specific, specialized applications.
-
Granulated activated carbon is used to dechlorinate water, adsorb organic materials, and create a chemical-reducing environment.
-
Granulated activated carbon is impregnated with silver salts, and it helps inhibit bacterial growth.
-
Catalytic activated carbon is effective at removing chloramines from drinking water.
-
Pelletized (or extruded) activated carbon is efficient at dechlorinating and removing chemicals.
-
Powdered activated carbon is applied to eliminate trace synthetic chemicals, taste and odour-causing compounds, and is also used for handling chemical spills and algal blooms.
Process Water Treatment
Process water, integral to industrial operations, encompasses both potable water, such as that used in juice production and consumption, and non-potable water, like wash water that is either discarded or recycled. Our activated carbon comes in a range of forms, sizes, and impregnations to effectively address diverse process water requirements.
Wastewater Treatment
Wastewater includes heavily contaminated water from industrial processes, agricultural chemical use, landfill leachate, and residential runoff. Wastewater treatment facilities must purify this water to meet acceptable standards before discharging it into lakes, rivers, or oceans.
We provide a range of activated carbon formulations and equipment designed to target specific contaminants in various concentrations in wastewater, including:
- Dissolved organic materials and micropollutants
- Heavy metals
- Hydrocarbons
- Pesticides
- Solvents
- Chlorinated hydrocarbons
Drinking Water Treatment
Activated carbon adsorption is widely recognized as one of the most effective and prevalent methods for removing impurities from drinking water, used both in municipal treatment facilities and home filtration systems.
Granular activated carbon can be employed in filter beds or media through which water flows, while powdered activated carbon can be introduced into the treatment process and then removed along with other solids from the water.
PFOA and PFOS
Scientific research has demonstrated that granular activated carbon filtration systems are effective in removing PFOA and PFOS contaminants from municipal drinking water.
Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been accumulating in the environment for years. These perfluorinated compounds, also known as PFCs, are raising significant concerns about their negative impact on human health, which is becoming a major issue for municipal drinking water providers.
Highly resistant to degradation and repelling both water and oil, perfluorinated chemicals are used in:
- Surfactants for fire-fighting foam
- Emulsifiers in floor polish
- Mist suppressants for metal plating baths
- Surfactants for etching acids used in circuit boards
- Pesticides for insect bait traps
- Antistatic agents in photographic paper
- Waterproofing casts and wound dressings
- Non-stick coatings for cooking surfaces
- Soil and water repellents for carpets, upholstery, and apparel
- Oil and water repellents for food containers and cartons
Our carbon is utilized in various water applications, including the production of filter cartridges, reverse osmosis systems, and the creation of highly purified water for dialysis treatment.
