“…Pure and crude glycerol was also used as DS [68]. Fresh human urine and hydrolyzed human urine were used as DS, which stimulated up to 3010 kPa osmotic pressure [76], comparable with the osmotic pressure of seawater at 25 • C. Similar results were observed for synthetic urine (both fresh and hydrolyzed) prepared according to previous research [79]. The ammonia contents in urine, however, inhibits microalgae growth.…”

“…The most explored microalgae were Chlorella vulgaris, with different strains from many culture collections, e.g., Chlorella vulgaris [67], Chlorella sp.ADE4 [69], Chlorella sp. KR-1 [72], Chlorella vulgaris (UTEX 2714, Austin, TX) [73], Chlorella vulgaris (FACHB-36) [74], Chlorella vulgaris KCTC AG 10002 [76]. The microalgae were cultivated with different media such as BG-11, modified bold basal media (BBM), selenite enrichment (SE), and Bristol medium (BM) in different bioreactors.…”

Nowadays the world is facing vulnerability problems related to food, energy and water demands. The challenges in those subsystems are intertwined and thus require inter-discipline approaches to address them. Bioresources offer promising solutions of the dilemma. Microalgae biomass is expected to become a superfood and a favorable energy feedstock and assist in supplying clean water and treat wastewater. Efficient mass production of microalgae, both during upstream and downstream processes, is thus a key process for providing high quality and affordable microalgae biomass. This paper covers recent progress in microalgae harvesting and dewatering by using osmotic driven membrane process, i.e., forward osmosis. Critical factors during forward osmosis process for microalgae harvesting and dewatering are discussed. Finally, perspective on further research directions and implementation scenarios of the forward osmosis are also provided.

“…Concentrated fertilizer solutions is an attractive candidate for FO draw solution as the diluted draw solution can be directly for agricultural cultivation [37]. Recently, several laboratory studies also explored the potential of ionic liquid [38], electro-responsive hydrogel [39], and human wastes [40] as draw solutions. It is worth mentioning that, the RO concentrate is also a potential draw solution candidate for FO process as the high salt concentration is favorably for producing high osmotic pressure to increase the permeation flux and enhance water recovery [41].…”

Production of potable water or reclaimed water with higher quality are in demand to address water scarcity issues as well as to meet the expectation of stringent water quality standards. Forward osmosis (FO) provides a highly promising platform for energy-efficient membrane-based separation technology. This emerging technology has been recognized as a potential and cost-competitive alternative for many conventional wastewater treatment technologies. Motivated by its advantages over existing wastewater treatment technologies, the interest of applying FO technology for wastewater treatment has increased significantly in recent years. This article focuses on the recent developments and innovations in FO for wastewater treatment. An overview of the potential of FO in various wastewater treatment application will be first presented. The contemporary strategies used in membrane designs and fabrications as well as the efforts made to address membrane fouling are comprehensively reviewed. Finally, the challenges and future outlook of FO for wastewater treatment are highlighted.

“…Also, CO2 and ammonia were simultaneously used to produce ammonium bicarbonate as a DS, which can be regarded as a fertilizer (Cai, 2016). Similarly, human urine was also used as a DS in the FO process (Volpin et al, 2019). In addition, different soluble gases may be applied as DS.…”

Renewable energy, water conservation, and environmental protection are the most important challenges today. Osmotic membrane bioreactor (OMBR) is an innovative process showing superior performance in bioenergy production, eliminating contaminants, and low fouling tendency. However, salinity build-up is the main drawback of this process. Identifying the microbial community can improve the process in bioenergy production and contaminant treatment. This review aims to study the recent progress and challenges of OMBRs in contaminant removal, microbial communities and bioenergy production. OMBRs are widely reported to remove over 80% of total organic carbon, PO4 3-, NH4 + and emerging contaminants from wastewater. The most important microbial phyla for both hydrogen and methane production in OMBR are Firmicutes, Proteobacteria and Bacteroidetes. Firmicutes' dominance in anaerobic processes is considerably increased from usually 20% at the beginning to 80% under stable condition. Overall, OMBR process has great potential to be applied for simultaneous bioenergy production and wastewater treatment.
