HS-CL

Vapor Phase, Sodium Thiosulfate Media

Hydrosil’s HS-CL is a zeolite-based media that is impregnated with sodium thiosulfate. The HS-CL is specially designed for removing chlorine, bromine, or chlorine dioxide from vapor streams. The theoretical capacity of HS-CL is approximately 8.0 percent by weight. The mechanism for chlorine/chlorine dioxide removal is a reaction with sodium thiosulfate. See the following chemical reactions:

Na2S2O3 + Cl2 + H2O = Na2SO4 + 2 HCl + S

The reaction of sodium thiosulfate with chlorine dioxide is as follows:

Na2S2O3 + 2 ClO2  + H2O = 2 NaHSO4 + 2 HCl

The HS-CL is typically used in pulp and paper facilities, chemical, fresh and waste water treatment plants.
