Why Cooperate Damo

Damo Technology’s pervaporation membranes exhibit high separation efficiency and high product recovery rate (>99%), with low product concentration in the permeate (<1%). They possess excellent acid resistance, suitable for a pH range of 2-8.5, greatly reducing the difficulty of raw material pretreatment. With high stability, these membranes can achieve organic solvent dehydration under liquid phase conditions. The operating conditions are mild, without phase transitions, and the process is simple. Featuring exclusive intellectual property rights, this technology is internationally leading.
