From waste to resource

A group of scientists working under the current International Scientific Consortium of BRICS Countries "From Waste to Resource" has developed a new compact membrane method for concentration of valuable salts from industrial wastewater for subsequent crystallization with simultaneous production of clean water. The first prototype of the installation was assembled in TIPS RAS. The principle of operation of this setup is based on the evaporation of water from the surface of a thin film of concentrated salt brine with a practically instant capture of water vapor with a porous membrane. This approach will allow concentration and extraction of target products from the aqueous solutions, solving current industrial and environmental problems. The study was published in the journal Desalination.
