Polymer-Based Nanocomposite Membranes for Water Treatment
Description. Membrane is a semi-permeable filter or film that allows certain molecules to pass through while rejecting others. This project aims to develop advanced nanocomposite membranes with improved performances for the removal of dissolved solids, organics and other contaminants from water. The membrane technology developed in this project can be used for drinking water purification, water softening, treatment of industrial and wastewater.
Different types of natural and synthetic polymers have been used in designing membranes for wastewater treatment. Examples include polyvinyl alcohol (PVA),,, polyamide (PA), cellulose acetate (CA), polystyrene (PS), polyethersulfone (PES), polyvinylidene fluoride (PVF), and chitosan (CS).
Carbon-based polymer nanocomposite membranes for oily
The objective of this review paper is to highlight recent advances in the application carbon-based polymer nanocomposite membranes for oily wastewater treatment.
For wastewater treatment and water regeneration, MOF can serve as fillers in thin-film nanocomposite (TFN) membranes and mixed matrix membrane (MMM) to form MOF-based composite membranes. MOF can also be used as matrices to form bare MOF membranes.
A Review on Porous Polymeric Membrane Preparation. Part I
1. Introduction. Membrane technologies, as efficient separation techniques, have been widely applied in several areas, especially for water treatment (drinking water and wastewater treatment) including disinfection, distillation or media filtration [1,2,3,4,5], pharmaceutical and biotechnology industries such as drug release [6,7], food industries such as membrane fractionation of milk [8,9
This paper focuses on the study of the most recent ultra-filtration techniques, based on porous polymer membranes, used for the treatment of wastewater from oil, mine and hydrometallurgical industries. The performance of porous membranes used in separation and recovery of oil and heavy metals from wastewater, was evaluated by the polymer composition and by the membrane characteristics, as it

Fundamentals of Membranes for Water Treatment
for waste water treatment and in membrane bioreactors are not always used in pressure vessels. Bundles of fibers can be suspended in the feed solution, and the permeate is collected from one end of the fibers13. Theory The theory governing fluid transport through membranes is often expressed as follows14: NA =ρAv −DAB∇ρA v v v (1)
The present strategy provides a way for rational design and controllable construction of high-performance photothermal membranes, showing great potential applications in seawater desalination, waste water treatment, and solution concentration. 4. Materials and Methods 4.1. Experimental Design
