The new ProPress is designed to meet the needs of the waste recycling, quarrying and mining sectors
CDE has unveiled its new ProPress high-performance filter press, adding to its lineup of water management and recycling systems.
Developed to meet the evolving needs of the construction, demolition, waste recycling, quarrying and mining sectors, the ProPress integrates the latest technological advancements to deliver operational efficiency and maximum water recovery.
The new ProPress made its debut during Hillhead 2024 in Buxton, U.K.
The filter press features patent-pending technology, and benefits from a flexible design and variable throughput that can be scaled to fit the processing volume of any operation.
“Tackling the most challenging of materials is our expertize. We’ve poured over 30 years of engineering excellence into the development of the ProPress,” said Darren Eastwood, CDE’s Business Development Director.
“We’ve listened to and worked alongside our customers around the globe to design a solution that is adaptable to their needs, be they in the waste recycling or natural minerals processing sectors.”
Unlike traditional filter presses, the system is dual feed, meaning sludge is fed from both sides of the ProPress for improved efficiency and faster cycle times.
Optimized sludge feed pressure also allows for faster dewatering to increase overall throughput. This is further supported by an overhead beam design that ensures reliability by reducing stress on the unit and improving its durability.
The ProPress features plates that are 25 per cent larger, measuring 2.5 metres by 2 metres. Greater chamber volume and overall fewer plates serve to provide maximum capacity on a smaller footprint and improve mechanical cycle times.
Plate shake tech
Safe and efficient maintenance is made possible by integrated plate-shaking technology, which addresses filter cake build-up within chambers to help reduce the need for manual intervention.
As well, an access walkway provides unobstructed access to carry out maintenance safely and efficiently.
CDE also included flush mounted drip trays that lock in place to reduce material entrapment and provide a secure maintenance platform for operators.
The smart design is supported by an innovative, multifunctional robot, which serves as the main workhorse for the ProPress, controlling plate opening, plate shaking, cloth washing, plate winch and the maintenance platform.
The CDE ProPress is available in a range of different sizes to suit all markets and applications. Available worldwide, the ProPress is also largely pre-assembled to expedite commissioning, allowing operators to get up and running quickly to help achieve fast return on investment.
ProPress process
As materials are washed and graded, the water used accumulates silt and other residues to form a sludge. A challenging material to process, that sludge is pumped under high pressure into the CDE ProPress, which consists of a sequence of plates, the composition of which forms a series of chambers.
As sludge is pumped under high pressure through the press, solid materials build within the chambers to form a filter cake which is dewatered to maximize water recycling and recover a by-product with multiple applications.
“Those needs were clear: sustainable water management was key to minimize freshwater dependency and maximize water recycling, all while improving processing capacity, reducing operating costs and minimizing maintenance downtime,” Eastwood said.

“The ProPress is our response to all of this and more and it is already delivering for our customers. By the end of the year, the ProPress will be found on eight plants across three regions, processing around 1,000 tonnes per hour of material.”
With the CDE ProPress, owners and operators can recycle up to 95 per cent of process water for immediate reuse in their wash plant while simultaneously recovering a filter cake product that can be used for pipe bedding and landfill capping. This eliminates the need for settling ponds, which typically require extensive maintenance, consume labour resources and incur significant costs.
Once the ProPress is commissioned, every customer is introduced to the CDE CustomCare team which provides aftersales support to help achieve maximum performance from their equipment.
“Our most significant product launch in recent years, the ProPress really encapsulates CDE’s purpose: to create our best world, a ton at a time. It represents a constant push for improvement to make our equipment, our customers’ operations and the sectors we operate in more efficient and less wasteful,” Eastwood said.
“We’re very pleased to finally bring this latest innovation to the wider market to help maximize the availability of our natural resources and reduce the industry’s waste burden.”
AggMax
At Hillhead, CDE also presented its AggMax 252SR scrubbing and classification system, which combines pre-screening, scrubbing, organics removal, sizing, stockpiling, fines recovery and filtrates removal on a compact chassis.
Also on display was the latest generation of FreeFlow, the fully mobile washing solution for aggregate and sand classification. Designed and built onto the bed of a semi-trailer for optimal mobility, the plant helps achieve maximum in-situ material recovery and boasts integrated water storage and recycling.
“We see the world through our customers’ eyes, and we engineer practical, scalable and proven solutions that address real-world problems, from the big picture issues concerning global sand shortages and the industry’s waste burden, to the everyday needs of our customers,” said David Kinloch, Director of Business Development, UK & Ireland for CDE.
