1. Company

The current wastewater and sewage disposal plants have reached their limit due

to their obsoleteness, ever-increasing pollutants and toughened environmental

regulations.

With its in-depth experiences in research activities in college and on-site consulting,

ANT21 has accumulated know-how in environmental technologies, especially in

water treatment technology.

ANT21’s goal is to solve environmental problems using its accumulated know-how

and to provide economic profits for businesses and agreeable environment for

people.

ANT21 is exerting its best efforts to achieve these goals with service oriented

mindset and unflinching determination.

ANT21 is committed to establish itself as an environmentally friendly business that

upholds customer values
