What is a thickener?
A thickener is generally used in slurry applications and in waste water management where large scale separation of unwanted fine-grained solids and liquids is required.
The thickener from Propel Industries produces high density underflow slurry and clear overflow water. Up to 85 to 90% water is recovered from the feed. The recovered water can then be re-used for further washing application.
The automation of the thickener has certainly ensured efficient operation and has lessened the dependency on man power.
Technology decoded – Key points
- A thickener facilitates gravity feed from the washing plant to ensure rapid settlement of solids in the thickener tank. The pumped feed and the turbulence caused by it is neglected.
- The feed well tank design at the centre further reduces the turbulence and feed to the centre of the tank makesmaximum available time for material settling.
- The integrated flocculant dosing system (FDS) pumps pre-mixed flocculant (coagulant) to the material in the feed tank to ensure rapid settlement of the slurry.
- A single hydraulic motor drivingthe integrated rake mechanism ensures even settling of the sludge with optimum sludge conditioning. This maximises the performance and efficiency of the thickener.
Propel AVTH Thickener
The AVTH Thickener from Propel Industries has a simple yet robust design, lesser space is required to accommodate settling ponds and maximum settlement of solids happens in the smallest area.
