OPS Thickener

OPS Thickener

The OPS Thickener is a high performance, small footprint mechanical thickner that can process 120m3/h of water on a footprint of 3m.

The thickener also easily converts to a traditional over-weiring clarifier which increases the flowrate up to 180m3/h. The unit is spilt into several distinct areas: 


  •  De-aeration zone
  • Polyelectrolyte contact zone
  • Water Clarification zone
  • Sludge Thickening zone
The sludge is removed using a torque instrument from the central stirrer which starts and stops the sludge pump system. Typically, the sludge would then be stored in a further mixed tank before being dewatered in a centrifuge or press.

OPS have a good understanding of water treatment chemistry; it is very important that chemicals are introduced in the right order, the right mixing and given the right contact time.

As engineering systems integrators, we combine cost efficient 'off the shelf' products with our high throughput proprietary processes. Integrated by best in class process control into a single solution individually engineered to site conditions, OPS deliver consistent performance, reliability and optimised life cycle costs.
