Product Description
Salted water is not always the same. Depending on whether they come from warm or cold oceans, closed or open seas, their salt content will vary. This is a short comparison between samples:
Brackish water:0,5 to 10 g/l, (TDS range: 500ppm to 10000ppm)
Northern Sea close to estuaries :21 g/l (TDS range: 10000ppm to 21000ppm)
Atlantic Ocean :35 g/l (TDS 35000ppm)
Mediterranean Sea :38 g/l (TDS 38000ppm)
Arabian Sea :45 g/l (TDS45000ppm)
Red sea: 41g/L (TDS 41000ppm)
Dead Sea :300 g/l. (TDS 300,000ppm)

| containerized seawater desalination system normally process |
SWRO Process steps introduction
| Pre-treatment | Feed water pump, Stainless steel 316L | Provide pressure for filters; |
| Quartz sand filter | Remove suspended particle and large impurity. In this system; |
| Active Carbon Filter (option) | Remove the color, free chloride, organic matter, harmful matter, ect; |
| Anti-scalant system | To add chemicals to remove some impurities and prolong thememebranes using/washing time(prevent membrane blocking) |
| Manual/Auto control valves | Flushing sand/carbon filter after some time |
| 5micron filter | Remove larger than 5 micro colloids in the water. In this system |
| | 1micron filter | Remove larger than 1 micro colloids in the water. In this system |
| Seawater RO Main Part | High pressure pump, Stainless steel 316L | Provide the high pressure to RO membrane; |
| Ro membranes | More than 98% desalination rate, can remove ions except H2O. |
| CIP system | To washing the membranes when it is blocked after using for long time |
| Electronic control panel | PC controller or PLC and HMI controller |

Buying Guides
Buying Guides
To find the most appropriate desalination for you, please advise following information.
1. Product/Clean/output water flow rate ( m3/hr, m3/day, Liter/hr,GPM,GPD etc.)
2· Product water purpose(industry process/driking water or others)
3 . Power (220/380V/415V/460V, 50 or 60 Hz) 3 phase.
4. If source water is tap water no need analysis report(We will make design as per TDS less than 1500ppm)
5. Source water from borehole/salt/brackish/lake water It is necessary to make water analysis report( TDS,Iron, Manganese, TSS, SDI or related parameter)
6. Any other detail requirement.please tell me as more as you know.
