“…PR for An-POME as the feed was determined by using an osmotic pressure of 1.58 bar for An-POME, established by Johnson et al [ 35 ], for theoretical water flux (J Wt ) estimation. The PR trends for An-POME as feed were opposite those of the PR for DI water as feed.…”

Fertilizer-drawn forward osmosis (FDFO) is a potential alternative to recover and reuse water and nutrients from agricultural wastewater, such as palm oil mill effluent that consists of 95% water and is rich in nutrients. This study investigated the potential of commercial fertilizers as draw solution (DS) in FDFO to treat anaerobic palm oil mill effluent (An-POME). The process parameters affecting FO were studied and optimized, which were then applied to fertilizer selection based on FO performance and fouling propensity. Six commonly used fertilizers were screened and assessed in terms of pure water flux (Jw) and reverse salt flux (JS). Ammonium sulfate ((NH4)2SO4), mono-ammonium phosphate (MAP), and potassium chloride (KCl) were further evaluated with An-POME. MAP showed the best performance against An-POME, with a high average water flux, low flux decline, the highest performance ratio (PR), and highest water recovery of 5.9% for a 4-h operation. In a 24-h fouling run, the average flux decline and water recovered were 84% and 15%, respectively. Both hydraulic flushing and osmotic backwashing cleaning were able to effectively restore the water flux. The results demonstrated that FDFO using commercial fertilizers has the potential for the treatment of An-POME for water recovery. Nevertheless, further investigation is needed to address challenges such as JS and the dilution factor of DS for direct use of fertigation.

“…This fertilizer driven forward osmosis (FDFO) could also avoid the energy requirements associated with the DS separation. The potential of FDFO has been explored to recover water from palm oil mill effluent (POME) wastewater, 108 petrochemical oily wastewater, 109 shale gas flowback and produced water (Sichuan Basin, China), 110 vegetable waste liquor, 111 and bioreactor treating domestic wastewater. 112 The details of the fertilizers used, membrane performance and water recovery are given in Table 5.…”

“…130 The use of lignosulfonates (Na/Ca) as DS gave a pronounced advantage as the diluted draw solution could be used for irrigation to enhance soil stability and control soil erosion. 108 Other organic DS such as potassium acetate, potassium formate, sodium glycolate, and sodium propionate has also been evaluated in lab studies. 131 Commercial aquaporin incorporated TFC (FO) membranes could suitably recover water from hot saline oily-wastewater (Petrochemical area, Iran) with a maximum flux of ∼68 LMH using 3 M KCl and operated in the PRO mode.…”

Forward osmosis (FO) is an osmotically driven membrane separation process. It is potentially applied in various industries for nutrient recovery and water reclamation. Although FO showed a lesser fouling tendency than other pressure-driven membrane processes, the solutes in the feed solution would still deposit on the membrane surface, forming a fouling layer that resists water permeation. For that reason, fouling mitigation is a trending issue in the FO process. A better understanding of the fouling mechanism is required before opting for the appropriate strategy to mitigate it. This article describes the fouling mechanism based on different foulant presented in the feed, followed by a method in relieving fouling in the FO process.
