Ceramic raschig rings are used as buffering materials in waste gas and wastewater treatment systems, creating a surface for the reaction between chemicals and the exhaust gas stream, increasing the retention time of the gas stream as well as the reaction time between the gas chemical waste and solution.
Technical specifications:
- Heat resistance: 1400 degrees C, stable in acidic or high basic environments
- Acid resistance: 85-98% (glazed and unglazed types)
- Compressive strength: 20 MPa
- Quantity / m3: 4000 (for pipe with specification 60x60mm).
- Quantity / m3: 6400 (for pipes with specifications 50x50mm).
- Quantity / m3: 14000 (for pipes with specification 40x40mm)
