Membrane E= xtraction Technology Ltd

Environmental Technologies=

= Organic acids and bases from industrial processes are often toxic and inhib= itory to biological treatment.

= With tighter legislative control on industrial processes and the economic d= rive to recover residual valuable products from process streams, MET’= s patented Membrane Aromatic Recovery System (MARS) is an attractive route = to significantly clean up your process streams and recover your high value = compounds.

= MARS can be applied to any organic molecule that exhibits acidic or basic f= unctionality. So,

· If you need to efficiently recover valuable chemicals in pure form…

· If you want a simple system witho= ut the need for vacuum or high pressure equipment...

… = ; couple MET’s MARS technology to your process!
