Q1. Why is filtration performance such an important issue for mining operations today?
A: Mining operations are under constant pressure to maximise throughput while controlling energy, labour, and maintenance costs. Filtration systems sit directly within the production chain, so even relatively small inefficiencies can have a disproportionate impact on overall plant performance.
As operations become larger and more demanding, there is also a greater focus on operational consistency, workforce safety, and minimising unnecessary process disruption. That means every part of the filtration system needs to contribute effectively to the wider operation.
Q2. What first made you focus on the filter press cloth feedneck as a problem worth solving?
A: Throughout my career in filtration, I kept seeing operators and maintenance teams forced to work around the same limitations without a viable solution. The feedneck is the highest abrasion area in filter press cloth and premature failures are common. They cause leakages, damaged filter plates, and difficult, time-consuming cloth changeouts, particularly in abrasive industries like mining.
What struck me was that many of these problems originated around the feedneck, yet there was no product available that solved all these problems at once. Over time, that became a real frustration for me and ultimately the starting point for a completely different way of thinking about the problem.
Q3. Why does the feed interface create so many operational challenges?
A: The feed interface sits at the point where slurry enters the press, so it experiences high velocities, abrasive materials, and constant mechanical stress. At the same time, filter plates naturally vary in geometry, wear condition, and tolerances.
That combination creates inconsistency at the interface between the plate and cloth, leading to uneven filter support, unstable sealing conditions, accelerated cloth damage and leakage. In many cases, operators end up managing the consequences rather than addressing the underlying cause.
Q4. How did that thinking influence the development of a new solution?
A: The breakthrough came when I stopped focusing purely on improving accepted industrial feedneck durability and instead concentrated on controlling the interface itself.
I approached the challenge from first principles and looked at how to create a more stable and repeatable connection between the filter plate and cloth. That process ultimately led to the development of the Cleanova OMNI™ feed interface system.
The objective was not simply to improve one maintenance task, but to create a more reliable and predictable operating environment across a wide range of filter press applications.
Q5. What practical impact can this feedneck redesign have in mining environments?
A: In mining operations, filter cloth replacement can be physically demanding work carried out under significant time pressure to restore production. Traditional methods often involve removing plates and pulling cloths through the feed opening, which increases handling difficulty and creates additional maintenance burden.
By redesigning the feed interface, it becomes possible to make the process more controlled and less physically demanding while also reducing the risk of filter cloth damage during installation. In practice, that supports safer working conditions, more consistent maintenance practices, potentially lower material costs and fewer interruptions to production.
Q6. What broader lessons does this hold for filtration in mining?
A: I think the most important lesson is that filtration should not be viewed as a downstream maintenance issue or an isolated specialist discipline. It has a direct influence on operational efficiency, equipment performance, uptime, and overall process stability.
At Cleanova, we believe the best innovations come from understanding how filtration interacts with the wider operation and then solving practical problems in a way that delivers measurable operational value. OMNI™ is one example of that approach. By rethinking a single connection point within the system, it is possible to influence performance much more broadly across the operation.
