Biomimetic membranes for forward osmosis application in industrial wastewater treatment
Jasmina Korenak, 2018, doktorska disertacija

Opis: The problem of wastewater is increasing as we face tighter regulations in limiting parameters for discharge into sewers or surface waters. At the same time, the challenge is also how to upgrade existing technology and identify new appropriate technologies for purification of industrial wastewater for re-use. The optimal solution, which can give the appropriate quality of purified water at acceptable operating costs also is not straightforward. However, increasing environmental legislative demands combined with increased fresh water consumption can facilitate implementation of emerging technologies which at the current state are not fully mature. Forward Osmosis (FO) is one such recent achievement which is considered as a promising membrane process and potentially a sustainable alternative to reverse osmosis (RO) process for wastewater reclamation and sea/brackish water desalination. However, there are many limiting parameters (e.g. membrane fouling, draw solutions) in FO process that needs to be studied and improved. To reduce the membrane fouling in FO, many improvements were attempted, e.g. synthesis of different membrane materials, fabrication of membrane modules, membrane coating etc. One of the novelties in membrane development research field is biomimetic membranes incorporate in separation processes. They employ natural proteins known as AQPs (aqpourins) to regulate the flow of water, providing increased permeability and near-perfect solute rejection. Membrane surface characteristics were measured on virgin, used and cleane membrane in order to confirm the resistance to different types of industrial wastewater and sewage.
