CARBTROL manufactures activated carbon filters for adsorption of organic compounds and residual disinfectants from water streams.  Activated carbon may also be used to remove undesirable odors and colors from other liquids such as ethanol.  A variety of high activity activated carbons are available to suit your application. All activated carbon adsorption equipment is designed for a low pressure drop.

Activated Carbon Filtration is ideal for high (>75 g/mol) molecular weight, low solubile organics.  Organics are less soluble and more adsorbable at a lower pH.  As the pH increases, removal decreases.  The upper limit for contaminant concentration is around several hundred ppm, for higher concentrations, hold time may need to be increased.  Contact our engineers for a consultation.

Ethanol (grain alcohol) has become a readily-available and inexpensive main ingredient in the manufacture of hand sanitizer. However, most of the ethanol available today contains undesirable odors and other impurities. By pumping ethanol through Carbtrol activated carbon filters, the undesirable odors and other organic impurities are removed and the ethanol is purified and deodorized. Typical odors removed include corn/musty odors, liquor/tequila/rum odors, and sulfur/egg odors. Typical organic impurities removed include acetaldehyde, methyl ethyl ketone (MEK), and sulfur-based compounds. 

CARBTROL's filters remove Polyfluroalkyl substances, known as PFAS.  PFAS are chemicals found in everyday items such as firefighting foam, non-stick cookware, and stain-resistant fabrics.  

CARBTROL also offers a range of solutions for eliminating chlorine and chloramine from water in order to improve water taste and protect other water treatment equipment.  We offer both standard activated carbon and catalytic carbons to meet our customers' particular needs.

Liquid phase carbon filters have capacities up to 600 gpm and are available in low pressure or high pressure design. High pressure units are available as NSF 61 Certified Filters for potable water and food/beverage applications.

CARBTROL activated carbon filters last significantly longer than competitor's units, delivering 15 – 20% greater bed life and performance.
