Technology description

The system facility using RO membrane to remove ions within the water by filtering water through the membrane with high pressure
Desalination facilities with highly efficient ion removal ratio at 99% or higher
Operation expense can be saved using energy efficient device (ERD)
Stable quantity of treated flow secured without blockage during mid to long term operation by regular cleansing (CIP)

INPUT Quality of original water
- Turbidity/SS
- TDS
  - Mg2+ㆍCa2+ (Major scale ingredients)
  - B
  - Na+,Cl- B
  - Temperature. pH
- Production quantity
- Quality of produced water
OUT PUT
- Pre-processing system
- Amount of medicines used (Bio Fouling, Scaling, Cl2 revivification)
- Recovery ratio RO system composition
- - Quality of processed water
  - Specification/quantity of tools and materials
  - Area of installation
  - Facilities cost
  - Expected production cost of water

System design

Optimal combination of minimum capital expenses (facilities cost) with minimum operation expenses by process
Experimental design technologies such as compact design and RO Membrane placement/arrangement design are required.
Decision factors for experimental design are important elements for deciding facilities and operation cost
Pre-treatment SYSTEM is determined by turbidity/SS level, and recovery ratio is adjusted according to ingredients/ level of TDS and RO contaminants
