Activated carbon is capable of adsorbing a wide range of organic substances, certain heavy metals and removing oxidising molecules (such as chlorine and ozone) from liquids and water. Typical applications for liquids and water purification are:
The purification of water like:
Aquarium and pond water (Removes heavy metals,odour,discolouration,organic contaminants and pollutants to leave aquarium water crystal clear).
Groundwater (BTEX, Chlorinated solvents, PAH)
Industrial wastewater (COD, AOX, EOX, TOC)
Landfill leachate (COD, AOX, TOC)
Municipal wastewater (Micro Pollutants)
Process Water (Feed water, condensate, ultra-pure water,…)
Swimming pool water (chloramines)
The purification of food grade ingredients and products:
Brewing and bottling industry (dechlorination, taste, odour)
Decaffeination of coffee and tea
Edible oil and related products like fatty acids, lecithin and glycerine
HVP (Hydrolised Vegetable Proteins)
Sweeteners (colour removal, colour stability)
and many others.
Several purification steps in industrial processes at petrochemical, chemical, pharmaceutical plants like the purification of:
and many others.
The purification of water intended for human consumption such as:
Home water and appliance filters
Point Of Use (POU) and Point Of Entry (POE) water treatment with in-line and through cartridge filters
Municipal and industrial drinking water production for
Disinfection by-products (DBP) removal (Trihalomethanes)
Micro pollutants removal such as endocrine disruptors
Natural organic matter removal (NOM)
Pesticides and pesticide degradation products removal (Atrazine, BAM,…)
Taste and odour removal (Geosmin, …)
Effectiveness of activated carbon purification of water and liquids
The effectiveness of activated carbon depends on:
The nature of the organic matter to be removed. Substances with a high molecular mass and low water solubility are adsorbed better.
The concentration of the substance to be removed (the loading percentage). The higher the concentration, the better the adsorption.
The presence of other organic compounds, which results in competition for the available adsorption space.
The parameters of the liquid (temperature, pressure, humidity, pH…).
