TL;DR: In this paper, a layer-by-layer (LBL) selective nanofiltration membrane was engineered from polydiallyldimethylammonium chloride (PDADMAC) and polysodium-4-styrenesulfoate (PSS) polyelectrolytes.

TL;DR: In this article, the authors used the central composite design of the response surface methodology to predict the maximum permeability and real salt rejection (Rreal) of the polysulfone (PSF) membranes, and the optimized responses, membrane permeability, and Rreal obtained experimentally were 61.9260 L m−2 h−1 bar−1 and 97.5850%, respectively.

TL;DR: In this paper, the degradation of industrial textile wastewater (SDWW) was investigated using a membrane photocatalytic reactor (MPR) in the presence of zinc oxide capped with polyethylene glycol (ZnO-PEG) nanoparticles and polypiperazine-amide (PPA) tight ultrafiltration membrane (UF-PPA).

TL;DR: In this article, the authors used Hermia's models to investigate the fouling mechanisms of polysulfone membranes in ultrafiltration and found that the characteristics of the membrane and feed solution were highly influential on the membrane fouling mechanism.

TL;DR: Silica-decorated graphene oxide (SGO) was used as a high-efficiency adsorbent to remove Congo red (CR) and Cadmium (II) from aqueous solutions and Thermodynamic study showed that the enthalpy and Gibbs free energy values of the adsorption process for both pollutants were negative, suggesting that the process was spontaneous and exothermic in nature.
