Metso pressure filtration will help decrease energy and environmental costs of TiO2 processing by achieving the driest possible filter cake with efficient filter cake washing.
Over 45 years of experience in TiO2 filtration
Over 100 filters delivered for TiO2 filtration worldwide
The combined surface area of all installed units is over 4000 m2
Every day, our filters produce over 300 t/h DS TiO2 filter cake
Metso’s solutions: Larox PF and Tube press
The primary dewatering mechanism for Titanium dioxide is pressure. Metso's solutions for dewatering of TiO2 are the Larox PF filter as well as the Tube press filter.
Larox® PF filters can achieve low residual filter cake moistures and high washing efficiency due to the horizontal cake formation.
Tube press filters can achieve the lowest possible residual moisture content for TiO2 filter cakes with the highest available pressing force.
Both, the Larox PF and Tube press filters provide lower and consistent residual filter cake moisture content compared to traditional filter presses, reducing the cost of drying after the filtration process. Metso has delivered over 100 pressure filters to TiO2 producers around the world, helping them save energy, reduce costs, and improve availability. Our filters are easy to adapt to both old and new production lines and can be installed with minimal downtime.
Benefits & applications
Achieve best filter cake wash efficiency and reduce residual moisture
Save energy, reduce wash water consumption, and increase plant capacity with Tube press and Larox® PF pressure filters for TiO2 dewatering and washing. Metso pressure filters and Life Cycle Services for calciner feed and finished pigment in industrial applications are based on our decades of experience and proven track record.
Our filters ensure a timely return on investment. They are easy to adapt to both old and new production lines and can be installed with minimal downtime.
In addition to their higher production capacity, our filters have lower running costs compared to conventional filter presses due to their lower energy & water consumption and minimize waste. The fully automatic operation ensures consistent performance while requiring minimal operator attendance.
