1. Overview of MCDI (Membrane Capacitive Deionization) Technology
O₂&B is Development of a modular, fully automatic package system for water treatment processes.We have advanced water technology and are in the process of Electricity 80% savings, SW management without the need for experts, recovery rate 90% or higherWe have MCDI water purification technology.
RO (Existing) VS MCDI (Our Technology)
RO (Reverse Osmosis)
High CAPEX | High OPEX
High pressure process, membrane fouling, periodic replacement, specialist required
MCDI (Membrane Capacitive Deionization)
Much Less Costs
Low pressure, zero chemicals, modularity, low maintenance costs
MCDI desalination technology principle
Ionic substances in water are applied to the surface of a carbon electrode. Electrically adsorbedand remove it.
The direction of the electrode is changed so that the attached substance can be easily separated. disposeIt will work.

3. 11 Key Advantages of the MCDI System
| No. | MCDI System Advantages |
|---|---|
| 1 | Since MCDI is a low-pressure system, general pipes, especially vinyl pipes, can be used, and the cost of construction materials is lower than that of existing RO. More than double the savingsIt will work. |
| 2 | The modular design and low-pressure piping configuration are highly flexible, allowing easy installation even for cross-operations for backwash or drainage. |
| 3 | Because it is a low-pressure system, professional installation and operation are not necessary, and the risk of pipe damage, etc. is extremely minimal. |
| 4 | The low pressure system is manufactured in cabinet form. Stacking method even in narrow areasIt can be installed and is easy to operate and manage. |
| 5 | In the absence of the operator continuous autonomous drivingThis is possible and reduces costs by minimizing expensive RO valves and computerized control systems. |
| 6 | Because repair materials can be installed as general materials in remote areas or overseas, Highest operating yieldno see. |
| 7 | It can be installed with general materials (plastic/vinyl, etc.) Air shorteningThis significantly reduces the overall construction cost. |
| 8 | Only the membrane filter needs to be installed in a fixed manner and can be supplied in one place as a HEAD type. |
| 9 | Because it can operate at room temperature, it only requires a heating system from the HVAC system. |
| 10 | Because it operates at low pressure Solar power and ESSIt can be operated stably even in remote areas using . |
| 11 | In the event of a pipe failure, the amount of leakage is small, minimizing the risk of loss of life or environmental pollution. (Superior safety compared to high-pressure RO) |
4. RO vs. MCDI: Comparison of Operating Costs (Example: 20 tons/day facility, 1 year)
Comparison of CAPEX (capital expenditure)
| division | water purification equipment | Heating, cooling and air conditioning | emergency generator | Installation work | Total cost (ten thousand won) | RO contrast |
|---|---|---|---|---|---|---|
| RO | 2,610 | 1,620 | 2,360 | 2,470 | 11,032 | 100% |
| MCDI | 3,240 | 170 | 700 | 480 | 5,040 | 45.7% |
※ MCDI shows significant savings in auxiliary facility costs (air conditioning, generator, installation).
OPEX (Operating Expenses per Year) Comparison
| division | Electricity bill | filter | Chemicals | inspection | personnel expenses | Total cost (ten thousand won) | RO contrast |
|---|---|---|---|---|---|---|---|
| RO | 883 | 60 | 65 | 120 | 913 | 2,174 | 100% |
| MCDI | 250 | 110 | 5 | 120 | 130 | 899 | 41.4% |
※ MCDI has a notable effect in reducing electricity bills, chemicals, and labor costs.
5. MCDI's Overwhelming Performance Compared to Global Technologies
Fluoride removal efficiency compared to similar technologies (CDI)
Similar CDI technology
31%76ppm → 41ppm
O₂&B MCDI
95%18ppm → 0.26ppm
O₂&B MCDI is World-class fluoride removal performancehas been proven.
