AquaCycle A2500 Thickener Responds to Needs of High Tonnage Processors

In 2022, CDE revealed its new AquaCycle A2500 thickener, the latest addition to its top-of-the-line water management and recycling systems. With a capacity of 41,600 l/min, the new A2500 is CDE’s largest and most advanced water management system to date.

It has been developed in response to calls from materials processors operating in high tonnage markets for water management solutions equipped to supply their operations with sufficient water supplies while ensuring optimal production efficiency, minimum loss of fines and maximum water recycling.

Designed for easy use and safe access for efficient maintenance, it boasts the first lattice bridge structure on any CDE thickener. An integrated monorail also provides unrivaled access to the motorized rake, gearbox and motor.
With a sludge capacity of 125 t/h, the A2500 includes an adjustable rake lifting mechanism. Featuring passive torque control, the automatic raise and start sequence is designed to protect rakes from surge pressure from dense sludges. The rake itself has also been reimagined, with optimally spaced and redesigned blades for improved sludge conditioning.

Powered by the motorized rake arm, the introduction of a new floating scum scraper, which is independent of the rake’s height, allows for the easy removal of unwanted foam, oil and light weight trash. And, creating even radial flow to all regions of the A2500, a redesigned volute feedwell optimizes the incoming flow for improved flocculant performance.

Another key feature of the new A2500 is its feed height. Sitting at over 6,6 m, it simplifies upstream plant design complexity as it eliminates the need for expensive civils, helping to expedite the commissioning process of entire plant solutions.

An alternative to water extraction from natural sources and the costly process of pumping water to the plant, CDE’s A2500, like the full AquaCycle range, significantly reduces costly water consumption by ensuring up to 90% of process water is recycled for immediate recirculation.
