Eliminate Settling Ponds

Settling ponds used to recycle water often encounter significant operational and logistical challenges. Settling ponds are known to be the source of significant revenue losses, not only due to high maintenance costs, site footprint, and downtime, but also because high-value fines can become lost and trapped at the bottom of ponds. This loss of fines is one of the key considerations in the design of CDE’s AquaCycle™ thickener.

Maximise the efficiency of your wet processing plant

The AquaCycle™ thickener is a single, compact, and user-friendly unit that can be applied to high and low tonnages across many markets. It is a highly efficient water management solution that minimises costly water consumption by ensuring up to 90% of the process water is recycled for immediate recirculation.

After feed material has been washed and classified, waste is sent to the AquaCycle™ thickener tank. Here, a small amount of polyelectrolyte flocculant is added to the water via an automatic dosing station which forces fine particles to settle on the bottom of the thickener tank. The clean water on the top overflows the weir and is stored in the AquaStore water tank before being re-circulated around the plant. The result is a highly efficient water recycling system that requires only a 10% supply of top-up water.

Return on Investment

Return on investment with a CDE AquaCycle™ thickener is typically achieved in just six to nine months.

By recycling up to 90% of process water, the requirement for settling ponds is greatly reduced. With the addition of a filter press tailings management system that need is completely eliminated. When combined with a CDE filter press custom-built fines management system this figure increases to 95%, removing the need for settling ponds altogether.

Delivering competitive advantage to its customers, CDE’s AquaCycle™ thickener accelerates return on investment by:

• maximising production efficiency
• minimising the loss of valuable fines
• reducing water and energy costs.
