Desalination
Fresh water is provided from seawater which is through desalination process.
Reverse Osmosis System and Multi-Stage Flush are utilized for desalination but prior treatment system can be required which can remove sludge and sea shells.As a prior treatment system, sand filtration can be set and remove particle sludge.

PROBLEM:
- Only normal backwashing, filter sand deteriorates gradually and be required to replace it periodically
- When filter sand is getting dirty, it affects treated water quality
- Filter sand may have deteriorated by bacteria
- Deterioration of treated water may shorten the desalination system life


SOLUTION:
- Introduce new cleaning system and keep filter media and water always clean
- As treated water quality is improved, desalination system life will be expanded and expect to save cost



General Treatment Process

Our Solution

 ADVANTAGES:

- No media replacement required
- Keep clean water quality
- Reduce 30-50% of backwash water
