Napier-Reid: GAC Towers
GAC TOWERS download brochure in PDF

Granular Activated Carbon (GAC) adsorbs dissolved organic contaminants from water into its structure. GAC Towers are usually proceeded by a conventional water treatment plant to pretreat the raw water. Contaminants removed by GAC include taste and odour, VOC's (volatile organic chemicals - trichloroethylene), SOC's (synthetic organic chemicals - pesticides) and polynuclear aromatic hydrocarbons (Nepheline).

GAC's are very effective at removing taste and odour problems from drinking water as well as providing a barrier to organic based chemical spills.

There are many design parameters in choosing the correct GAC tower, which are dictated by the contaminant(s) and its concentration. Variables in design include: choice of carbon (lignite, peat, bone bituminous etc.), empty bed contact time (EBCT), bed surface loading rate and carbon particle size.
