Desalination and Nanofiltration through Functionalized Laminar MoS2 Membranes

Laminar MoS2 membranes for molecule separation.

For the first time, a laminar separation membrane was assembled from atom-thick MoS2 sheets and exhibited a water permeance of 245 L h(-1) m(-2) bar(-1), which was 3-5 times higher than that of graphene oxide membranes without degradation of the rejection ratio (89%) for Evans blue molecules.

Isotherm Studies for Performance Evaluation of Functionalized Carbon Nanotubes (CNT) Based Polymer Composite Nanofiltration Membranes for Desalination

Composite Nanofiltration membranes were fabricated by incorporating Carbon Nanotubes (CNT) and Polyvinylidene Fluoride (PVDF) membranes. A suspension was prepared by dispersing CNT (30 minutes of sonication) in Dimethyl Sulfoxide (DMSO) solvent for 0.5 mg/ml. This suspension after vacuum filtration dispersed over PVDF membrane of pore size 0.22μm. Excess DMSO was removed by washing using Ethano...

Nanofiltration Process Efficiency in Liquid Dyes Desalination

Membrane science and technology has led to significant innovation in both processes and products over the last few decades, offering interesting opportunities in the design, rational‐ ization, and optimization of innovative production processes. The most interesting develop‐ ment for industrial membrane technology depends on the capability to integrate various membrane operations in the same in...

Seawater Desalination by using Nanofiltration (NF) and Brackish Water Reverse Osmosis (BWRO) Membranes in Sequential Mode of Operation

In this study, the applicability of nanofiltration (NF) membranes as a pretreatment prior to reverse osmosis (RO) in seawater desalination was investigated. The membranes used wereNF270 and NF90 as the NF membranes, while the brackish water (BW) RO membrane BW30 was used as the RO membrane. In desalination tests, permeates of the NF membraneswere collected and used as the feed to th...
