What Is the Spares’ Expected Lifetime?

A lifetime of filter parts depends on many factors. First of all, it depends on the part itself, exactly which one are we talking about? Some of the parts are under heavy tear and wear and others are doing lighter jobs. For example, filter cloths are known to be subject to immense pressures and mechanical loads. On average, the filter cloth is in use for approximately 6000 cycles. This means that during its lifetime, a filter cloth can discharge up to 120 million kilos! Their lifetime is much different than let’s say, filtrate hose’s lifetime.

For more information about the spare part’s lifetime you are interested in, it is best to contact our filter service professionals.

Key Performance Indicators Shown on Only One Screen

One of the best improvements of Smart Filtration, is getting the big picture of the complete filtration process at one glance. In addition, it is possible to view the filtration process in real time and remotely. All you need is a computer or any other handheld device with an internet connection. Through Roxia Malibu™, an online portal, Terrafame personnel with user credentials can access the filtration information. The most important data is collected on only one screen. For Juha Paavilainen, Process Engineer at Terrafame, this makes his job much easier.

“Before, the information about filtration process was hard to access and read. I didn’t have the time to try and get through big amount of data. There are three tower press filters operating in Terrafame’s zinc production and I could only see what the overall production rate was. Now, with Roxia Smart Filtration, I can open my laptop in the morning and from one screen instantly see, how the filtration process is going. Within a couple of minutes, I know what is happening at the moment: what is the utilization rate, productivity, cake weight, waiting times, average cycle duration, etc. If I wish, I can move the slider and observe the filtration process throughout the past 72 hours,” Paavilainen explains.

Terrafame’s Filtration Process Improvements

The three tower press filters in Terrafame’s process are of the same size and model. From the technical point of view, they should perform in nearly the same way. Roxia analysis has shown this is not the case.

“For some reason, we noticed more slurry is pumped into the filter number 2. The productivity of the newest filter, which should be the highest, is for some reason the lowest. In comparison to the other two, one of the filters has an extremely high pressure peak, when pressing starts, which could result in premature breaking of diaphragms,” explains Aimo Rautanen, Product Manager, Textiles & Elastomers at Roxia. All those discoveries were previously unknown to Terrafame. “I did not know the pressure peak was that high. This was an important find because if diaphragms break too soon, we face more downtime and higher costs,” confirms Paavilainen.

Roxia Brings Significant Savings

Another example how Roxia has helped Terrafame to optimize the filtration process, is by detecting extremely high consumption of compressed air by one of the filters. Drying with compressed air is a big expense, about 80 % of all energy costs of the filtering process.

“By comparing the use of compressed air with one filter to another, I discovered one of them is consuming much more energy. I lowered the compressed air consumption and cake moisture was not affected but the energy costs have significantly decreased,” explains Paavilainen.

With this valuable information, provided by Roxia filtration specialists, Terrafame can now detect minor issues and use the data to prevent major failures. “We can remotely observe the filtration process and also get alarms if some values exceed the normal situation. Through the real-time online view, Roxia can support Terrafame and help optimize the filtration process. The filtration specialists can remotely find malfunctions and advise how to eliminate them,” adds Simo Rounela, Application Manager, Digital Services at Roxia.

No DCS Integration Required & Full Data Protection

Smart Filtration is a turnkey solution and is completely safe. With Terrafame’s filters, Roxia uses existing filter sensors to read the data. DCS (Distributed Control System) integration is not necessary, but it can be arranged upon request. Roxia is using its own internet connection to send the data to the cloud. Smart Filtration is secured by SSL/TLS encryption; the same technology is used in internet banking. Roxia Smart Cube collects the data. System is configured as a read-only, so it is completely safe and cannot disturb Terrafame’s process control in any way.

“I am using the Roxia Smart Filtration on a daily basis. It gives me a fast insight to the filtration process and works extremely well. We have already requested from Roxia to expand the service to other parts of the process,” concludes Paavilainen.

Heart of the Tower Press

Tower press filters are extremely durable machines and can last for tens of years. However, its spare parts do wear off and need to be changed. The most important is the filter’s plate pack, also known as the “heart” of a tower press.

Depending on the process and its conditions, the complete filter plate pack can last up to a decade. To keep the tower press in shape, it is recommended to upgrade the entire plate pack when it wears down to the point when mechanical issues, bending of the plates or similar problems occur.

Replace complete set of filter plates

At that point, it is much more efficient to replace the entire set of filter plates at once, rather than changing one by one. One of the reasons lies in downtime – any maintenance break means the filter needs to be stopped and production is cut off. By replacing old, worn filter plates with new, tower press regains its original shape and is ready to bring many more years of efficient production.


Regularly inspect and when needed, replace old, worn tower press filter plates. Roxia filter service professionals offer complete service for the entire plate pack refurbishment or replacement.

Do you need assistance with filter maintenance and other issues?

Roxia experienced filtration professionals can serve all customer needs regarding filter service and filtration.
