The combination of the Larox "C" Series Automatic Pressure Filter together with a Scheibler "A" Series Polishing Filter provides a superior solution for the recovery of Magnesium Hydroxide from naturally occurring brine solutions from processes using a thickener / clarifier for the hydroxide recovery.

The "C" Series Automatic Pressure Filter is operated with cake washing to reduce the residual Cl^- levels in the filter cake to < 100 parts per million, while at the same time the Scheibler "A " Series Polishing filter can produce a clarified filtrate containing <20 parts per million solids in the exiting stream. The solids discharge from the polishing filter is in the form of a sludge that goes back into the feedwell of the thickener, effectively ensuring 100% recovery of the precipitated Magnesium Hydroxide.

The same configuration can be used for any process around a thickener / settler or clarifier where the solids need to be isolated and a very clear filtrate is required.

Larox "C" Series advantages

• Superior washing with reduced wash water

• Fully automatic operation ensures lower operating costs

• Drier filter cake reduces downstream costs

Scheibler "A" Series advantages

• No moving parts

• Cleaner filtrate – as low as 10 – 20 ppm

• Pre-coat or body feed not required

• Short cleaning / discharge cycle recycles back to thickener

• Very low energy usage - low pressure feed only
