Vietnam's National Goals for 2030

The water is overflowing,
There is no water to drink.
The Vietnamese government is investing billions of dollars in a 'national clean water supply strategy'.
However, water contaminated with arsenic and heavy metals cannot be treated with existing technologies.

The global water crisis is pushing technology to its limits.

Worldwide, fluoride, arsenic, and heavy metal contamination is on the rise, and RO systems are failing due to high costs, high power consumption, and difficult maintenance.

Problem: Limitations of RO Systems

RO equipment supplied through ODA stops operating within 6 months to 1 year due to excessive electricity costs and frequent filter clogging.

Ghana: Suspended after 6 months
Ethiopia: Suspended after one year

Global Water Resources Status

Available fresh water is 2.8%

pollution problem

Groundwater is contaminated with harmful ionic substances such as fluoride, arsenic, lime, and iron, which cause endemic diseases and shortened life expectancy.

Africa: High Fluoride Concentrations
Southeast Asia: High concentrations of arsenic

Next-Generation Solution: O₂&B's MCDI Technology

MCDI, which adsorbs only harmful ions using electrochemical principles, is a low-cost, high-efficiency, and eco-friendly technology that overcomes the limitations of existing RO methods.

MCDI operating principle

enemies (including ions)

Water purification process (electrosorption)

(-)pole
+ (cation) - (negative ion)
(+) pole

Purified water (clean water)

Regeneration process (electrode reversal)

Adsorption and desorption of ions by electrode reversal (self-cleaning)

Overwhelming cost savings compared to RO

(20 tons/day, based on 1 year of operation)

Proven Performance: Exceeding Third-Party and Industry Standards (1/2)

O₂&B's MCDI outperforms existing technologies in key performance indicators: removal rate, recovery rate, and power efficiency.

Core Performance Comparison (vs RO, CDI)

MCDI has both high removal and recovery rates.

Power consumption comparison (kWh/ton)

Overwhelming energy efficiency, 1/5 that of RO

Proven Performance: Exceeding Third-Party and Industry Standards (2/2)

It has also demonstrated outstanding performance in fluoride removal and industrial wastewater treatment.
