CDE has introduced its new AquaCycle A2500 thickener, the latest addition to its water management and recycling systems.

With a capacity of 11,000 gallons per minute, the A2500 is CDE’s largest and most advanced water management system to date.

The system was developed in response to calls from materials processors for water management solutions to sufficiently supply their operations, while ensuring optimal production efficiency, minimum loss of fines and maximum water recycling.

“It is increasingly important for materials processors to invest in an effective water management system that ensures a steady supply of clean water to their plants through cost-effective means,” said Darren Eastwood, business development director for the Americas at CDE.

“The continued advancement of our pioneering wet processing solutions and leading-edge water management systems is supporting operators working in the natural processing and waste recycling sectors worldwide to overcome the challenges of washing in water-pressured or water scarce areas today.”

Where CDE bridged the gap in 2018 with the launch of its A900 and A1500, providing a median alternative to its 2,642 gpm and 6,604 gpm models, the new A2500 expands the range with a 11,000 gpm option to fit the requirements of sites processing high tonnages. The increased capacity also provides a lower rise rate, enabling operators to process challenging, hard-to-settle materials.

A first for CDE 

Designed for easy use and safe access for efficient maintenance, the A2500 is equipped with 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 138 tons per hour, 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 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. As well, creating even radial flow to all regions of the A2500, a redesigned feedwell optimizes the incoming flow for improved flocculant performance.

Another key feature of the new A2500 is its feed height. Sitting at almost 22 ft., it simplifies upstream plant design complexity as it eliminates the need for expensive civils.

With a tank diameter of 65.6 ft. and a weight of 97 tons when empty, the A2500 features a small footprint.

“It responds directly to the needs of materials processors operating in high tonnage markets. These operations, primarily in the areas of C&D waste, specialist sands and heavily clay-bound aggregates, require higher volumes of water resources; they need flexible water management systems with the capacity to supply their operations without compromising on footprint; and they need a system that can deliver this in a way that improves efficiency, driving down operational costs to maximize profitability and enable fast return on investment,” Eastwood said. “These are the guiding principles that underscore the design and development of the new A2500.”
