Thickeners and Clarifiers
Parnaby thickeners and clarifiers have a special profile and an internal moving rake designed to achieve the rapid settlement of solids in water. We make a range of cones from 3m to 20m diameter capable of throughputs of between 30 and 1,000 cubic metres per hour.
- High throughput
- Low flocculant requirement (e.g High Midlings content)
- Modular design
- Easily assembled
- Does not need to be bolted to foundations
- New cones can be added to existing systems
Examples of our range of thickeners and clarifiers
Effluent is pumped from the sump to the top of the cone. A polymer flocculant is added (2) which causes fine particles to bind together and settle rapidly. Clear water overflows from the top of the cone (5) into a storage tank. The sludge at the bottom of the cone (which usually contains 30 – 35% solids) is pumped to a conditioning tank.
- Sand and Gravel
- Road Sweepings
