The performance of a newly commercialized aquaporin (AQP)‐based biomimetic forward osmosis (FO) membrane was evaluated with several commonly used fertilizers ((CO (NH₂)₂, KCl, CaCl₂, (NH₄)₂SO₄ and (NH₄)2HPO₄) as a draw solutions (DSs) to verifying the possible implementation of this AQP‐FO membrane in the fertigation industry. Also, DS and feed solution (FS) concentrations were evaluated under FO and pressure retarded osmosis (PRO) operation modes. The results showed that CaCl₂ seems to be a more suitable DS in terms of the tradeoff between water flux and salt permeability, compared to the other DSs used in this study. However, KCl gained the highest performance in terms of water flux which was 13.9 and 24.1 Lm⁻² h⁻¹ in the FO and PRO mode, respectively. The performance of the AQP membrane in terms of water flux and reverse solute flux can be improved by modifying the structural and the membrane inhibitor layer characteristics for utilizing in commercial scales to compete with other available membranes of the FO process.

以化肥为汲取液对水通道正渗透膜的性能评价

使用几种常用的肥料（（CO（NH ₂）₂，KCl，CaCl ₂，（NH ₄）₂ SO ₄和（NH ₄）2HPO ₄）作为汲取溶液（DSs ），以验证该AQP-FO膜在施肥工业中的可能应用；此外，还评估了在FO和压力延迟渗透（PRO）操作下DS和进料溶液（FS）的浓度结果表明，CaCl ₂与本研究中使用的其他DS相比，在水通量和盐渗透性之间的权衡方面，似乎更合适的DS。但是，就水通量而言，KCl在FO和PRO模式下分别表现出最高的性能，分别为13.9和24.1 Lm ^-2 h ^-1。AQP膜在水通量和反向溶质通量方面的性能可以通过修改结构和膜抑制剂层的特性进行改进，以用于工业规模，以与FO工艺的其他可用膜竞争。
