New composite sorbents for solar-driven technology of fresh water production from the atmosphere

In this communication we present new selective water sorbents developed at the Boreskov Institute of Catalysis (Novosibirsk, Russia) and discuss their application for fresh water production from the atmosphere. We present a g eneral scheme of the water production and suggest the particular solar-driv en unit which may be recommended for desert areas with a hot and dry climat e. The results of our lab- scale tests have demonstrated a feasibility of t he fresh water production with the output of 3-5 tonnes of water per 10 ton nes of the dry sorbent per day.
