Fabrication of high-performance pervaporation composite membrane for alkaline wastewater reclamation

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 5,   Pages 709-719 doi: 10.1007/s11705-021-2078-2

Abstract: Pervaporation desalination has a unique advantage to recycle concentrated salt solutions. The merit can be applied to treat alkaline wastewater if the membrane has superior alkali-resistance. In this paper, we used polyethylene microfiltration membrane as the substrate and deposited a glutaraldehyde crosslinked sodium carboxymethylcellulose layer by spray-coating. Pervaporation flux of the composite membrane reached 35€±€2 kg·m–2·h–1 with a sodium chloride rejection of 99.9%€±€0.1% when separating a 3.5 wt-% sodium chloride solution at 70 °C. The desalination performance was stable after soaking the membrane in a 20 wt-% NaOH solution at room temperature for 9 d and in a 10 wt-% NaOH solution at 60 °C for 80 h. Moreover, the membrane was stable in 4 wt-% sulfuric acid and a 500 mg·L−1 sodium hypochlorite solution. In a process of concentrating a NaOH solution from 5 to 10 wt-% at 60 °C, an average water flux of 23 kg·m–2·h–1 with a NaOH rejection over 99.98% was obtained.

Nucleate boiling in two types of vertical narrow channels

Lei GUO, Shusheng ZHANG, Lin CHENG

Frontiers in Energy 2011, Volume 5, Issue 3,   Pages 250-256 doi: 10.1007/s11708-010-0128-4

Abstract: To explore the mechanism of boiling bubble dynamics in narrow channels, we investigate 2-mm wide I- and Z-shaped channels. The influence of wall contact angle on bubble generation and growth is studied using numerical simulation. The relationships between different channel shapes and the pressure drop are also examined, taking into account the effects of gravity, surface tension, and wall adhesion. The wall contact angle imposes considerable influence over the morphology of bubbles. The smaller the wall contact angle, the rounder the bubbles, and the less time the bubbles take to depart from the wall. Otherwise, the bubbles experience more difficulty in departure. Variations in the contact angle also affect the heat transfer coefficient. The greater the wall contact angle, the larger the bubble-covered area. Therefore, wall thermal resistance increases, bubble nucleation is suppressed, and the heat transfer coefficient is lowered. The role of surface tension in boiling heat transfer is considerably more important than that of gravity in narrow channels. The generation of bubbles dramatically disturbs the boundary layer, and the bubble bottom micro-layer can enhance heat transfer. The heat transfer coefficient of Z-shaped channels is larger than that of the I-shaped type, and the pressure drop of the former is clearly higher.

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 1,   Pages 65-72 doi: 10.1007/s11783-010-0010-y

Abstract: The limiting chlorine demand, which quantifies chlorine reactive natural organic matter (NOM) on an equivalentbasis, was mathematically defined by the relation between ultimate chlorine residue and initial chlorineIt was found experimentally that NOM in water has limiting chlorine demand that increases with chlorineThe results also demonstrated that the effect of chlorine dose on the rate of chlorine decay can be quantitativelyinterpreted with the limiting chlorine demand.
