Metso Outotec has introduced a filter optimiser which boosts the performance of its Larox PF filter in mining and chemical industry processes.

The filter optimiser improves the PF filter performance by enabling more precise control over the solid/liquid separation process. It stabilises the effect of upstream process variations, provides tools for improved process control and reduces the need for manual intervention.

The filter optimiser enables automatic adjustment of filtration as well as pressing and air drying setpoints based on filter performance. Compressed air usage is enhanced in the controlled air-drying sequence, resulting in improved energy consumption.

Leena Tanttu, senior manager, Process and Testing of Filters at Metso Outotec, said: “The new filter optimiser automatically adjusts the filter’s process performance, adapting to upstream process variations. Instead of relying on manual moisture sampling and cake-weight monitoring, new setpoints are calculated on the go and adjusted automatically.”

The optimiser has remote connectivity, giving rapid OEM expert support for fine-tuning of the system parameters and further optimisation of performance. An integrated historical database increases process visibility and provides a powerful tool for performance evaluation.
