Magnesium Hydroxide Recovery
Category: Filtration | 07/02/2008 - 09:22:59
Larox offers a superior optimalsolution for the recovery of Magnesium (as Magnesium Hydroxide) from naturally occurring brine solutions producing a filter cake of magnesium hydroxide with around 100 ppm chlorides and a filtrate containing < 20 ppm suspended solids, thereby ensuring essentially 100% recovery of the precipitated magnesium hydroxide.
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.
- 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
