Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 6,   Pages 1108-1116 doi: 10.1007/s11783-015-0806-x

Abstract: High-solids anaerobic digestion of sewage sludge was a promising process, but high solid concentrationThe results showed that TS 6% was the boundary between low-solids and high-solids anaerobic digestionThe concentration of VFAs reached the maximum at the initial stage, which were still lower than the thresholdThe concentration of free ammonia increased gradually, and the methanogenesis was inhibited when freeConsequently, the deterioration of high-solids anaerobic digestion was related to the blocked mass transfer

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.
