Thickener or Thickener plant
Thickener is an equipment designed for solid liquid separation by gravity settling. The main goal of the thickener or of a thickener plant is to separate the solid & liquid part from the slurry and to concentrate as much as possible the solid part in the bottom of the thickener in order to get from the top of the thickener, clear water as much as possible free from the solids.
Thanks to many years of operational experience, Cogede design, manufacture & supply Thickeners for different industrial sectors like Mining, Quarry, Sand & Aggregate & other industrial sectors.
Cogede design, manufacture & supply wide Range of Thickeners:
HIGH RATE THICKENER
High rate Thickener are used to concentrate as much as possible the solid in the bottom of the Thickener.
Cogede Design High Rate Thickener
High Rate thickener with central drive unit
The last technology of high rate thickener or thickener plant developed by Cogede allow to optimize the consumption of polyelectrolyte by special feed well design.
The High rate thickener are equipped with a Sedicontrol system that monitors continuously the flocculation and adapt the polyelectrolyte dosing according to the right settling speed. In this way the thickener plant is able to guarantee automatically constant settling performance.
High rate Thickener in mine
The feed well of the Cogede High rate Thickener can be also customised in order to guarantee an optimum flocculation by an auto dilution system or by force dilution system according the specific characteristic of the slurries.
Moreover our High rate thickener have a system that allow us to measure continuously the effort on the rake and by a system of hydraulic jacks to move up and down the thickener’s Rake in order to have constant concentration thickener output and to avoid any mechanical problem on the mechanism.
The Cogede high rate thickener or thickener plants can be installed on tank made in carbon steel or on tank made in concrete.
The High Rate Thickener or thickener plant are mainly used in the mining application for tailing management and for concentrate thickening and in all that application where it is important to reach an high concentration of solid in the thickener underflow.
The Clarifier thickener are used in the case where the slurry has a low concentration of solids. The main goal to apply the clarifier thickener is to reach an high quality of water in the overflow output.
Usually in the clarifier thickener Cogede use peripherical drive unit because the concentrated sludge in the bottom of the Thickener is not of very high density and the specific weight of the solid part is not very heavy.
On the clarifier thickener Cogede can install the Sedicontol device in order to monitor the settling process and to optimize the polyelectrolyte consumption.
The clarifier thickener are equipped with a manual hoist that allow to move up and down the rake in case of any need. The Cogede clarifier thickener can be installed on tank made in carbon steel or on tank made in concrete, all the solutions can be customized according to the process requirement.
DEEP CONE THICKENER
The Deep cone thickener technology is the oldest thickening technology used for solid liquid separation by gravity settling process.
Cogede start to produce Deep Cone Thickener many years ago. The Cogede Deep Cone thickeners are used in different sectors like, quarry, ceramic, stone, marble, mining etc.
Deep cone thickeners
On the Deep Cone thickener Cogede can install the Sedicontol device in order to monitor the settling process and to optimize the polyelectrolyte consumption.
The Cogede Deep cone thickener can be made in painted carbon steel, in hot dip galvanized Steel, Stainless Steel etc.
The lamella thickener is a settling technology that use many inclined plates. This lamella thickener design allow to increase the settling surface and so the settling speed.
The main advantage of the Lamella thickener is that it is possible to treat a big volume of dirty water in small footprint compare to the other thickener technologies.
The Cogede lamella thickeners are used in different industrial waste water treatment plants and the lamella thickener can be made in painted carbon steel, in hot dip galvanized steel, Stainless Steel etc.
The type of Thickener is been selected following specific project slurry characteristics & clients performance requirements.
