Seitz AKS4 series depth filter sheets were developed to satisfy general purpose carbon adsorption applications in the food and beverage industry.

Powdered activated carbon (PAC) is widely used in the food and beverage industry for adsorption applications. The use of bulk PAC has significant drawbacks relating to the handling of bulk carbon powder, cleaning of the process equipment, as well as time and costs associated with carbon removal from the process.

Seitz AKS immobilized carbon filter media alleviates these concerns by incorporating activated carbon within a matrix of cellulosic fibers. This immobilized carbon media can be coupled with a downstream protective filter paper to prevent any possible carbon particle shedding downstream of the filter. Additionally, the adsorption efficiency of Seitz AKS immobilized carbon filter media is greater than an equivalent amount of bulk powdered activated carbon (PAC), reducing overall process time and increasing product yield. An internal comparative study using the same carbon grade showed up to 150 % better color removal efficiency when compared to bulk PAC.
