A great variety of acidic waste gases and vapours are created during the manufacture of crystalline or amorphous solar cells. Very fine aerosols and respirable fine dusts in the range of lower than 0,1 µm are also created during processes.
VSS-Umwelttechnik supplies these industries with individual, economic solutions.
Gas scrubber as single and as two-stage scrubbers are used worldwide to eliminate hydrofluoric acid (HF), silicium tetra fluoride (SiF4), chlorine (Cl2), nitric acid (HNO3) or nitrous gases (NOx).
Two stage gas scrubbers are also installed as preliminary scrubbers to catalytic SCR facilities, for gas separation and to protect the following facility components.
Venturi scrubber are used where the finest acidic aerosols after phosphor doper facilities, and SiO2 dusts behind incineration plants, must be separated.
