Home > Product Information > Reverse Osmosis Membrane
Compared to other desalinisation processes such as multi-flash distillation or electrodialysis, filtration through RO membranes is better cost-efficient since it requires less energy and/or maintenance.

The products for low pressure use can perform at the same level as our competitors' products but requiring 2/3 of the pressure. Our low pressure membranes also have the effect of lowering installation costs as well. Main applications for Low pressure elements are the same as for our BWM (brackish water) products.
