ProPress high-performance filter press enhances its advanced water management and recycling systems.

CDE, renowned for its sand and aggregate wet processing solutions in waste recycling and natural minerals processing, has introduced its new ProPress high-performance filter press at Hillhead, enhancing its advanced water management and recycling systems.

Developed for the construction and demolition (C&D) waste recycling, quarrying, and mining sectors, the ProPress incorporates cutting-edge technology to ensure high operational efficiency and optimal water recovery.

ProPress advantages

The ProPress, featuring patent-pending technology, boasts a flexible design and adjustable throughput to match any operation's processing volume. Unlike traditional filter presses, it offers dual feed, allowing sludge to be fed from both sides, enhancing efficiency and reducing cycle times. Optimised sludge feed pressure expedites dewatering, boosting overall throughput. An overhead beam design reduces stress on the unit, enhancing durability.

With plates 25% larger (2.5m x 2m), the ProPress offers greater chamber volume and fewer plates, maximising capacity within a smaller footprint and improving mechanical cycle times. Integrated plate-shaking technology reduces filter cake build-up, minimising the need for manual intervention. An access walkway allows safe, efficient maintenance, and flush-mounted drip trays prevent material entrapment, providing a secure platform for operators.

The ProPress is supported by a multifunctional robot that handles plate opening, shaking, cloth washing, plate winch, and maintenance platform tasks. Available in various sizes to suit global markets and applications, the ProPress is largely pre-assembled to expedite commissioning, ensuring quick start-up and rapid return on investment.

During the washing and grading of materials, water collects silt and residues, forming sludge. This sludge is pumped under high pressure into the ProPress, which comprises a series of plate-formed chambers. As sludge is pumped through the press, solids accumulate within the chambers to form a filter cake, which is dewatered to maximise water recycling and recover a valuable by-product.

The ProPress allows owners and operators to recycle up to 95% of process water for immediate reuse while reducing waste disposal costs by recovering a filter cake product suitable for pipe bedding and landfill capping. This eliminates the need for maintenance-intensive, labor-consuming, and costly settling ponds.

CDE’s business development director, Darren Eastwood, said, “Tackling the most challenging of materials is our expertise. We’ve poured over 30 years of engineering excellence into the development of the ProPress. 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.

“Those needs were clear: sustainable water management was key to minimise fresh water dependency and maximise water recycling, all while improving processing capacity, reducing operating costs, and minimising maintenance downtime. 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 1000tph of material.

“Our most significant product launch in recent years, 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. We’re very pleased to finally bring this latest innovation to the wider market to help maximise the availability of our natural resources and reduce the industry’s waste burden.”

According to the results of the second ecological transformation survey, which was carried out by Veolia and consulting firm Elabe, 81% of UAE citizens are certain that climate disruption will occur, and 54% of them are hopeful that humanity will still control the future and that the costs of ecological transformation will outweigh the costs of climate disruption.

The results are included in the second edition of Veolia's study, The Barometer of Ecological Transformation, which aimed to find out how people throughout the world felt about the current approaches to combating pollution, biodiversity loss, and climate change. The Barometer seeks to facilitate more solution-focused conversations in order to shorten the public's perspective of ecology.

High price of climate change

In the face of the "climate and ecological wall," according to the most recent Veolia survey, 81% of respondents in the United Arab Emirates are positive that climate change is occurring, even though 21% of them are still unsure about its anthropogenic origin. Of them, 14% believe that climate change is a purely natural phenomenon, and 7% say that it is impossible to pinpoint its cause. In the last study, 61% of respondents said they thought climate change was genuine, suggesting a 20% increase this year.

The majority of respondents to the study, or roughly 64%, also agreed that the expenses connected with climate disruption considerably outweigh the investments needed for ecological transformation, underscoring the financial losses brought about by climate change.

Comparing this year's UAE survey results to last year's, there was a 19% increase in respondents who would be willing to pay more for locally produced energy with lower CO2 emissions and a 23% increase in respondents who would pay more for everyday products made from recycled materials.

Positivity regarding ecological change

Notwithstanding these obstacles, a sizeable segment of the population in the United Arab Emirates expressed optimism regarding the chances of ecological change, expressing hopes characterised by better consumption patterns, increased unity, higher living standards, improved tranquilly, improved health, a readiness to give up old habits, increased purchasing power, and general happiness.

The poll also revealed a notable rise in the acceptance rates of a number of behaviours, including consuming food grown with sewage sludge, drinking water treated by wastewater treatment, washing dishes and clothes with recycled water, and cutting back on meat intake.

The UAE survey's overall results are consistent with the global trends observed by the Barometer, which indicates that over two-thirds of the world's population is facing ecological challenges. The findings show that most people (89%) acknowledge that climate change is happening and that people (97%) would rather put their health before their finances when making decisions about energy, waste, and water use. Furthermore, despite possible cost increases, two-thirds of respondents from around the world expect higher costs from inaction and are open to health-focused alternatives.
