Zeolite-Coated Mesh for Oil-Water Separation

BACKGROUND Daily water demand and the increasing amount of industrial oily water discharge have become a worldwide problem. The presence of oil in water not only influences the surroundings but also damages the self-cleaning circulation of the ecological system at the time of recycling produced water. In the past few decades, polymeric membranes have...

Atomic Layer Deposition (ALD) Modified Membrane Systems for Desalination

BACKGROUND Only a few studies were reported on the ALD modified inorganic membranes for desalination. Alam et al. grew TiO2 ALD on polyethersulphone (PES) membrane. It was shown that the TiO2-film deposited PES membrane exhibited >90% NaCl rejection (4 times higher than uncoated membranes) in a pressurized desalination at feed pressure of 8 atm...

Polyamide Membranes Incorporating Metal Organic Frameworks for Water Treatment

BACKGROUND As groundwater is pumped from water wells, there usually is a localized drop in the water table around the well, called a cone of depression. When there are many wells that have been pumping water for a long time, the regional water table can drop significantly. This is called groundwater mining, which can force the drilling of deeper,...
