The Delkor Ultrasep concept permits a very high allowable rise rate in the thickener and thus reduces the required thickening area significantly, affording a far more cost-effective thickening solution. The Ultrasep thickener has no moving parts and thus the need for maintenance is virtually eliminated.
It is used in the metallurgical and mineral processing industry for mill circuit thickening, counter current decantation, backfill and carbon-fines recovery, dewatering and water recovery and slag treatment.
Benefits
• Process adaptability
• Optimised underflow density
• Optimised overflow clarity
• A tolerance to process fluctuations
• Low flocculant consumption
• Minimal environmental impact
• Automated operation
• Quick start-up and stabilisation
• Small footprint minimises plant size
• Bolted construction reduces delivery time
• Reduced capital outlay
• Reduced operating cost
• Low maintenance cost
• Short delivery and installation time
• Retrofit potential
• Mobility
• Zero spares requirement
The Ultrasep is manufactured to international quality standards and the design permits short delivery and installation times. Its capital cost can be as low as 50% of the cost of a conventional thickener performing the same duty.
General operation of Ultrasep
The Ultrasep functions on three principles:
• Diluted slurries, once flocculated, settle more readily than undiluted slurries
• Reduction of velocity of flocculated slurry resulting in settlement of
solids out of suspension
• Slurry settling on inclined surfaces slides down the surface and consolidate, realising water
Control philosophy
The control of Ultrasep is governed by the following factors:
• Underflow on density basis
• Flocculent addition by settlement optimiser
• Level control
• Monitoring control
Sizing of Ultrasep
The sizing can be conducted in different methods such as:
• Laboratory test work
• Manual calculation based on client’s data sheet
• Pilot plant trials
