Industrial reverse osmosis ro water treatment plant
Different user have difference output ro industrial water quality requirement.
Reverse osmosis water treatment equipment has a compact structure, covers an area of small and convenient operation and other advantages, in the industrial processing industry, the degree of automation is relatively high, so it has been widely used in water treatment.
Reverse osmosis membrane technology belongs to a kind of membrane separation technology, in industrial water treatment, drinking water, salt water desalination treatment has a more important role.
The following is an introduction to several commonly used reverse osmosis equipment process, can be applied to industrial water and drinking water
For drinking water process:
1)Source tank →Sand filter→ carbon filter→Softener→Hight pressure pump→ RO system→ Clean water (RO permeated water).UV ultraviolet is for option.
2)Source tank →Sand filter→ carbon filter→Softener→ultra filtration→ Clean water (RO permeated water).UV ultraviolet is for option.
For the industrial reverse osmosis ro water treatment plant
- Source tank →Pretreatment parts→ Single RO system→ RO tank→EDI system →10MΩ/cm outlet water.
- Source tank →Pretreatment parts→ Single RO system→ RO tank→Mixed bed →10MΩ/cm outlet water.
- Source tank →Pretreatment parts→ doulbe RO system→Double RO tank→EDI system →15MΩ/cm outlet water
- Source tank →Pretreatment parts→ doulbe RO system→Double RO tank→EDI system →Polish resin filter→ 18 MΩ/cm outlet water
- Source tank →Pretreatment parts→ cation resin →anion resin →Middle tank→Mixed bed →DI water→15MΩ/cm outlet water
For industrial water output water quality.
Conductivity less than : 5us/cm.
Conductivity : 1us/cm.
Conductivity : 0.1us/cm
Resitivity:15MΩ/cm or 18 MΩ/cm
Advantages:
Consistent high-purity water
Can handle high variations in feedwater chemistry
Proven, long operating history
Most plant operating personnel are familiar with this process
Disadvantages: If use the mixed resin then need chemical
- Requires chemicals
- Chemical feed storage tanks required
- Neutralization process required
