chemical carbonate removal with pellet reactor – Gyrazur™
Clarifier with optimized flocculation using external sludge recirculation
The Gyrazur™ is a water upflow equipment. It allows water carbonate removal (reduction of its hardness) by chemical precipitation in a reactor containing calcium carbonate in pellets or grains. Also used to remove nickel.
The carbonate removal consists of three parts: lime dispersal zone (inflow), reaction zone, separation zone.
application
- Water with flow rate of suspended solids
- Limited range (70 to 100%) for one unit
running with lime
- Lime slurry (lower reaction kinetics)
- Lower speed (higher work)
- Circular
- Metallic
- No floor
- Simple lime
- Injection device
running with caustic soda
- Liquid caustic soda (stronger reaction kinetics)
- Higher speed (lower work)
- Square or circular
- Concrete or metallic
- Floor
- Complex injection device
key figure
- High speed: 60 to 80 m/h

- Hanningfield (England) 10,000 m3/h
- Chen Chin Lake (Taiwan), 18,000 m3/h
profit
- Compact precipitate (carbonate pellets), no need of dewatering
- Reduce footprint
