Abstract null null The flue gas desulfurization wastewater (FGDW) contains extremely high concentration of heavy ions (e.g., Ca2+, Mg2+) and unbiodegradable organic pollutants such as humic substances. In this paper, the effects of softening pre-treatment on water reclamation performance and membrane fouling phenomenon of the direct contact membrane distillation of FGDW were investigated systematically. Results showed that fouling on the membrane caused by crystallization of CaSO4, Mg-Si complex...

Abstract Membrane wetting and fouling represent the foremost concerning issues confining membrane distillation in the treatment of industrial wastewater. This work presents a superhydrophobic poly(vinylidene fluoride) (PVDF) membrane with anti-fouling property, which was derived from the bioinspired adhesive, mineralization and fluorination process for the direct contact membrane distillation (DCMD). The synthesis of membrane was initiated by co-depositing polydopamine/polyethylenimine composite...

Abstract In this paper, the effects of high molecular weight additive (PEO-PPO-PEO), low molecular weight additive (oxalic acid) and inorganic additive (nano-TiO2) on PVDF membranes were studied by phase inversion method. The experimental results showed that the contact angle decreased as PEO-PPO-PEO was added in the casting solution. With the increasing concentration of PEO-PPO-PEO from 0.5 to 3.0 wt.%, the water flux increased from 0 to 1136 L/m2h and the rejection decreased from 99.0% to 64.0...

Abstract In this work, a modified direct contact membrane distillation (MDCMD) with receiving solution in permeate was developed for accelerating ammonia removal from aqueous solution. The ammonia removal efficiency by means of DCMD, hollow fiber membrane contactor (HFMC) and MDCMD was comparatively investigated. And the effect of feed pH, temperature, flow rate and concentration on ammonia removal efficiency and the permeate flux in MDCMD process was studied. Experimental results showed that th...
