HCM CITY — The Halvo Ltd company of Japan has successfully tested its technology in Viet Nam that will be used to purify water and treat waste water.
The company’s technology, which uses condensed organic substances, will be used to supply clean water in a sustainable manner in the central province of Ha Tinh and the Cuu Long (Mekong) Delta province of Vinh Long. Later, the company will expand its activities to HCM City and other provinces.
The main component of the organic substance is volcanic ash sourced from Japan.
Over the last three years, Halvo has given funds to 29 localities in Ha Tinh and Vinh Long provinces to buy its products, Kiyomarukun and HOH, which treat wastewater and purify water.
The products are used at preschools, elementary schools, middle schools, hospitals, municipal offices and dormitories.
The water treatment technique can be easily installed, and saves time and money.
“At first, the price of the product will be the same as other treatment techniques, but it will fall later, depending on the market. However, it is environmentally friendly and takes much less treatment time, five times less, compared with other methods,” Yoshiharu Yagyu, director of Halvo Viet Nam Ltd Company, told Viet Nam News.
The company established Halvo Viet Nam One Member Ltd. in April in Long An Province’s Phuc Long Industrial Zone.
Its activities are part of a project to support developing countries that use technologies invented by small- and medium-sized enterprises from Japan.
Halva is funded by the Japan International Co-operation Agency (JICA).
Rapid development, industrialisation and modernisation in Viet Nam have caused industrial wastewater, pesticides and other pollutants to affect lakes and underground water.
Water pollution has become an urgent national issue, as water treatment facilities, particularly in poor rural areas, are limited.
The lack of such treatment facilities has led to increased cases of diarrhea and skin and eye diseases among the public.
Household water in many rural areas, as well as in some areas in Ha Noi and other large cities, does not meet safety standards, a Halvo company press release said.
