| Operations |
|
| Operational cost |
|
| System Cost |
|
 |
|
| Superior! - fewer moving parts |
|
| Low - double membrane barrier |
|
| Lower energy consumption (built-in energy recovery),
no chemicals metering |
|
Superior! - lower maintenance; higher efficiency
of cooling tower; lower health risk |
|
Lower cost of chemicals, energy,
and maintenance |

|
| Many points of failure |
|
| MF integrity risk, chemical dosing failure, fouling |
|
| High energy consumption, chemical use |
