CDE has launched its new Aquacycle A1500 thickener
CDE has launched the Aquacycle A1500 thickener following its installation at a site operated by Creagh Concrete in Northern Ireland.

The addition of the A1500 to the Aquacycle range represents the completion of a significant R&D programme and will ensure increased opportunities to specify thickeners on the washing plants installed by CDE throughout the world, according to senior design engineer with CDE, Paul O’Neill.

“As we make progress in areas like South Africa and Australia, the A1500 allows for the introduction of a single unit on projects with high processing tonnages. Up until now multiple machines were required to deal with the high processing throughputs that are typical in these areas,” says O’Neill.

The A1500 has a capacity of between 1,000m³-1,500m³/hour determined by the material being processed.

“In a typical sand and gravel application the dirty water processing capacity will be approximately 1,500m³/hour. On ore processing applications capacities will be determined on an individual project basis to allow for the effective treatment of sludge containing material with a significantly higher specific gravity,” says O’Neill.

One of the many product developments on the Aquacycle A1500 is the redesign of the rake mechanism which is employed to condition the settled sludge within the thickener before it is discharged to the next phase of processing or the settling ponds, and this design will be introduced across the full Aquacycle range.

“The new four-arm rake mechanism ensures maximum settlement of the sludge within the thickener while also ensuring its density is optimised for effective discharge via the integrated slurry pump,” explains O’Neill.

“Over 80% of all our projects now include some form of water treatment across all feed materials and geographies,” says CDE sales director Enda Ivanoff. “The launch of the A1500 will allow us to realise further sales opportunities in the coming months.”

The Aquacycle A1500 has a tank diameter of 15m and is constructed with the elevated cone design present across the range. The full Aquacycle range covers capacities from 1,000m³-1,500m³/hour across five models.
