“…Although researchers have reported a number of seawater desalination methods, for example, ultrafiltration membrane or reverse osmosis purification, nanomaterial filtration, most of them have the defects of high cost, and complex preparation processes, etc. [2][3][4][5] As a clean and efficient method, solar steam generation (SSG) can produce water vapor by using solar energy, without involving complicated engineering and high cost. [6,7] Meanwhile, SSG technology holds the promise of purification and removal of organic pollutants from water samples, providing a powerful means to repair the eco-environment.…”

Solar steam generation (SSG) has been regarded as a promising technique due to its potential in seawater desalination. Photothermal conversion materials derived from biomass are good evaporators for SSG because of their sustainability and high efficiency. Herein, 3D cylindrical structured composite materials based on gourd flesh and polypyrrole (GPPY) were designed and used for high efficient SSG. The polypyrrole layer was deposited on the gourd flesh to provide broad optical absorption ability and high photothermal conversion efficiency. Besides, gourd flesh with porous structure could act as thermal insulators, confine the generated heat within the evaporative surface and facilitate the efficient transport of water to the photothermally active area. Based on these characteristics of the composite, the evaporator made of GPPY could achieve a high evaporation rate of (1.63 kg·m‐2·h‐1), and a superior photothermal conversion efficiency 95.8% under one solar irradiation (1 kW·m‐2). The GPPY could be expected to be a practical photothermal conversion material for commercial SSG based on its high efficiency and sustainability.This article is protected by copyright.

“…To overcome these challenges, membrane separation as an efficient separation technology has become a research hotspot. In numerous lab-scale experiments, reverse osmosis (RO) and nanofiltration (NF) have been used to treat wastewater and concentrate liquids in a variety of applications. − However, the RO system for printing and dyeing wastewater is always confronted with more serious membrane fouling compared with RO systems used in other wastewater. High energy consumption is still the main obstacle for RO in wastewater treatment.…”

Printing and dyeing wastewater has characteristics of high pH, poor biodegradability, complex composition, and a large amount of water, which means it remains a daunting environmental issue. The development of efficient and economic printing and dyeing wastewater treatment technology has gained considerable interest in the field of environmental protection. The performance of ultrafiltration/ forward osmosis (UF/FO) hybrid system focused on recycling valuable materials in actual printing and dyeing wastewater was investigated. The effects of pressure, temperature, membrane orientation, and feed pH on membrane performance were also studied. The results showed that the optimal pressure and temperature (T) are 0.15 MPa and 25 °C, respectively; active-layer facing feed solution (AL-FS) mode at pH 7 was used for a UF/FO hybrid system. The recovery of terephthalic acid (TPA) was 99.78% under pH 4. This paper provided a resourceful proposal for the treatment of printing and dyeing wastewater.
