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.

A Study on Project of Land-creation by Sand Retaining in Three Gorges Reservoir

Han Qiwei

Strategic Study of CAE 2003, Volume 5, Issue 5,   Pages 31-34

Abstract:

The resettlement and loss caused by inundation at Kaixian in the area of the Three Gorge Reservoir is tremendous. The proposals of “large protection” and “small protection” schemes for reducing the inundation have been rejected. A scheme of land creation by sand retaining and water sluicing has been proposed by the author. The principle of this proposal is to keep the water of Xiaojiang River to flow out, but retain the sediment at river bed and flood plain. In this case the sediment is taken as a useful resource to heighten the level of land, on which a lower levee will be easily constructed to protect the farmland along the Xiaojiang branch reservoir.The original farmland will turn to be more rich and be preventable from drought and water logging disaster all the year. All together 37.8 thousands mu (2, 495 hect.) farmland will be protected and 11.0 thousands mu (726 hect. ) flood plain will be changed to farmland. This area can compensate nearly the total inundated land of 50.3 thousand mu (3, 320 hect.) at Kaixian. The feasibility study supported by the Ministry of Water Resources is now carried out. This scheme with its low cost and big profit can be applied to the similar project.

One-Step Reverse Osmosis Based on Riverbank Filtration for Future Drinking Water Purification Perspective

Yujia Zhai, Gang Liu, Walter G.J. van der Meer

Engineering 2022, Volume 9, Issue 2,   Pages 27-34 doi: 10.1016/j.eng.2021.02.015

Abstract:

The presence of newly emerging pollutants in the aquatic environment poses great challenges for drinking water treatment plants. Due to their low concentrations and unknown characteristics, emerging pollutants cannot be efficiently removed by conventional water treatment processes, making technically, economically, and environmentally friendly water purification technologies increasingly important. This article introduces a one-step reverse osmosis (OSRO) concept consisting of riverbank filtration (RBF) and reverse osmosis (RO) for drinking water treatment. The OSRO concept combines the relatively low-cost natural pretreatment of river water with an advanced engineered purification system. RBF provides a continuous natural source of water with stable water quality and a robust barrier for contaminants. With the pre-removal of particles, organic matter, organic micro-pollutants (OMPs), and microbes, RBF becomes an ideal source for a purification system based on RO membranes, in comparison with the direct intake of surface water. OSRO treatment removes almost 99.9% of the particles, pathogens, viruses, and OMPs, as well as the vast majority of nutrients, and thus meets the requirements for the chlorine-free delivery of drinking water with high biostability. The OSRO treatment is cost effective compared with the standard conventional series of purification steps involving sprinkling filters, softening, and activated carbon. Artificial bank filtration (ABF), which functions as an artificial recharge in combination with a sand filtration system, is proposed as an alternative for RBF in the OSRO concept to supply drinking water from locally available resources. It is also suggested that the OSRO concept be implemented with wind power as an alternative energy source in order to be more sustainable and renewable. An OSRO-based decentralized water system is proposed for water reclaiming and reuse. It is suggested that future water treatment focus on the combination of natural and engineered systems to provide drinking water through technically efficient, financially feasible, resource reusable, and environmentally relevant means.
