|
Case-1 |
RO + MB |
- Applied to source water with low hardness and alkaline level. - Recovery rate of RO must be low. |
|
Case-2 |
DG + RO + MB |
- Applied when alkaline level is usually high or when it has a decisive role in forming of scale of RO - Recovery rate of RO to 90% or more if silica concentration is not a problem can be maintained. |
|
Case-3 |
SC or WC + DG + RO + MB |
- Applied to source water with low hardness and alkaline level. - Recovery rate of RO to 90% or more if silica concentration is not a problem can be maintained. |
|
Case-4 |
SC + DG + SA + RO + MB |
- Applied when alkaline level, hardness, and silica level of source water all act as preventing agents to increasing of recovery rate of RO. - Recovery rate of RO to 90% or more can be maintained. |

Case-5 |
WC + SC + DG + WA + SA + RO + MB |
- Applied when concentration of plus ion and minus ion within water is very high, and quality of RO processed water and amount of regenerated waste water become problems. |

| Other | Various arrangement is possible according to water quality condition of source water | - Various system composition if possible by integrating conditions of source water and conditions of processed water quality, recovery rate of RO that user wants, regeneration period of MB etc. |
