De.mem, a Singapore-based water and waste water treatment firm, has sold a water treatment plant in Kim Lien Commune, Nam Dan district, Nghe An province to a local Vietnamese company Hung Thanh Environment Investment Joint Stock Company for approximately $400,000.

Under a build, own, operate (BOO) scheme, the water treatment facility was designed, built, owned and operated by De.mem, prior to the sale.

High quality output water for municipal and industrial sectors is generated by the water treatment plant, which treats 4000m3 of water a day, by using customized hollow fibre membranes.

To modernize the facility, the Hung Thanh will buy the membrane technology of De.mem, which remotely monitors the performance of the water treatment plant.

De.mem CEO Andreas Kroell said: “The sale of De.mem’s water treatment plant marks a significant transaction within the Vietnamese water treatment market, where membrane based water treatment is emerging.

“The transaction underlines De.mem’s growing brand and market position in Vietnam as a supplier for modern water treatment technology. It also brings along a strong validation of our BOOT/BOO (Build, Own/Operate, Transfer / Build, Own, Operate) product offering.”

Established in 2013, De.mem specializes in de-centralised water treatment and waste water treatment, and offers services in two segments such as the industrial segment and the municipal and residential segment. It employs 50 people.

The technologies used by the firm are approved by Nanyang Technological University in Singapore.
