Speech Title: Laser Synthesized Gold- Nanoparticles, Blend NF Membrane for phosphate Separation from Wastewater

Abstract: Phosphates are vital and their natural resources as rocks are depleting quickly. Different sources of phosphate wastewaters present a real problem and were banned for soil fertilization in many countries due to pathogens in municipals and presence of other micro-pollutants or heavy metals. In this work, nanofiltration membrane ( NF) will serve as a excellent opportunity to separate trivalent PO4--- in a concentrate and let mono- and divalent in permeate according to stringent environmental legislation and coping with phosphate recovery strategy. Improved fouling resistance and enhanced hydrophilicity were reached by optimized polymer blend with gold nanoparticles. Rejection % of 96.1 was achieved for NF-membrane supported with woven polyester and corresponds to permeability of 4.72 L/ at 0.1% gold in polymer blend. Alkaline feed water was found to be favorable for this polymeric blend membrane in presence of gold nanoparticles.
