Remarks: | 1. Pure water flux is measured with pure water at 25°C with inlet water pressure of 0.1MPa. | ||
2. If water are from surface water,river water or well water and so on,pre-treatment shall be done. It is suggested that a 50-150 um precision filter shall be equipped to have inlet water with turbidity ≤15NTU. | |||
