The exhibition in Hanoi (Vietnam) was a success. Over three days, our stand was visited by more than 500 people. Of particular interest was the model of the universal complex for washing NEPTUN FMS-A01. As it turned out in Vietnam, there is an acute issue with quality drinking water. Of interest was the industrial filter FM-B12 with a capacity of 500 m³ per hour. New water treatment technologies are needed at newly constructed facilities throughout Vietnam.
