| APPLICATIONS: |
Arsenic Removal
Under ideal conditions MetalEase-AS5 will reduce 50 ppb of arsenate to less than 10 ppb for more than 500,000 gallons per cubic foot. Limiting factors are high pH, high silica concentration, and high sulfate concentration. Capacity can also be reduced by intermittant operation and various foulants, notably suspended solids. |
| |
 |
| |
| THROUGHPUT CAPACITY — Capacity is based on clean waters that do not contain significant levels of organics, iron, manganese, or other contaminants. The graph above is based on 50 ppb of arsenate (As+5) in the feed, and TDS less than 500 ppm. MetalEase-AS5 removes only modest amounts of As+3, therefore pre-oxidation to As+5 may be required. No engineering downgrade has been applied. |
| |
Silica Removal
MetalEase-AS5 can be used at moderate pH to remove silica. At a flow rate of 0.5 BV/min, removal efficiency of ninety percent is possible for several hundred bed volumes of throughput. Silica does not dump as the resin exhausts. Even though silica removal is not complete, some lowering of silica occurs for hundred of thousands of bed volumes. |
