Case 2
Project Overview
In Brazil’s iron ore dewatering sector, stable filtration is not just about spare parts — it is about keeping production running.
For this project, an iron ore mine in Corumbá, Brazil, operating three Outotec 2000×2000 filter presses, planned to replace key filtration consumables and source them from China.
To support this replacement, Dofil Filtration Equipment supplied:
110 membrane plates
110 chamber plates
400 filter cloths
Before production, our engineer traveled to the customer’s site in Corumbá, Brazil, to carry out a full filter plate measurement and filter press data survey, helping ensure better compatibility and a lower-risk replacement process.
THE CHALLENGE
The customer’s real concern was not simply buying new filter plates.
The challenge was how to replace plates on three large mining filter presses without creating new problems.
For an iron ore tailings dewatering line, even a small mismatch in plate size, ports, sealing faces, or load points can lead to:
leakage after installation
unstable filtration cycles
repeated adjustments on site
costly downtime across multiple presses
The customer needed a solution that could deliver not just supply, but compatibility, stability, and lower replacement risk.
THE SOLUTION
To make the replacement more reliable, Dofil Filtration Equipment moved the key work forward — before manufacturing even started.
First, our engineer visited the Brazil site to verify the real operating conditions of the Outotec 2000×2000 filter presses.
This included:
plate dimensions and structure
port layout and sealing faces
installation interfaces and support points
operating data from the filter press line
Based on this survey, we prepared a complete replacement package of 110 membrane plates, 110 chamber plates, and 400 filter cloths, designed to match the customer’s mining filtration requirements and reduce the risk of “fits, but runs unstable.”
“The close cooperation and strong trust from our local partners, together with the stable and efficient operation of DOFILTRATION’s professional filtration solutions, have provided a solid boost to our production efficiency and sustainable development.”
