Metso Outotec has introduced a Filter Optimizer to further boost the performance of its Larox® PF filter in the mining and chemical industry processes.

The optimiser improves the PF filter performance by enabling more precise control over the solid/liquid separation process, according to the company. It is intended to stabilise the effect of upstream process variations, provide tools for improved process control and reduce the need for manual intervention.

In mining processes, the new Filter Optimizer complements Metso Outotec’s other advanced control solutions for concentrator plants consisting of the Grinding Optimizer, Flotation Optimizer and Thickener Optimizer, the company says.

The Filter Optimizer enables automatic adjustment of filtration as well as pressing and air drying setpoints based on filter performance. Compressed air usage is optimised in the controlled air-drying sequence, resulting in optimised energy consumption, Metso Outotec says.

Leena Tanttu, Senior Manager, Process and Testing of Filters at Metso Outotec, said: “The new Filter Optimizer 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.”

Thanks to the optimiser’s remote connectivity, rapid OEM expert support is available for fine-tuning of the system parameters and further optimisation of performance, the company says. An integrated historical database increases process visibility and provides a powerful tool for performance evaluation.

Metso Outotec’s Filter Optimizer typical scope of supply includes:

• Moisture analyser;
• APC system (server, control room operator interface, VPN router for remote connectivity);
• Engineering and project management including control design and set up;
• Comissioning including system implementation, start-up and controller fine tuning; and
• Operator training.

In addition to filters, Metso Outotec says it provides a full scope of services for filters, including process optimisation services, optimiser performance reporting, annual on-site maintenance visits, remote and on-site support, and more.
