Special Issue Information

Dear Colleagues,

Circular agriculture is essential to our sustainable future by closing the loop of materials and energy to enhance agricultural production while reducing resource demand and waste generation. For instance, nutrients, such as nitrogen and phosphate, in livestock manure and other formats of biomass can be recycled in agronomic activities to reduce the usage of chemical fertiliser. With the rapid development in membrane science and technology, membrane processes have been recently used in agricultural production. On one hand, membrane filtration can provide clean water for agricultural irrigation, for example, by desalinating seawater, treating wastewater, and capturing water in the air. On the other hand, nutrients and clean water can be recovered from agricultural waste streams (e.g. livestock wastewater) by membrane processes for internal recycling. Nevertheless, membrane application is still in the infant stage and thus requiring further research to boost industrialization. This Special Issue solicits theoretical, application-oriented, experimental, and real-world research to demonstrate the advances in membrane processes for agricultural applications.

Guest editors invite papers on the following topics:

  • Advanced membrane materials and processes for irrigation water production
  • Advanced membrane materials and processes for agricultural wastewater treatment
  • Novel membrane processes for nutrient recovery
  • Economic and environmental assessment (e.g., life cycle assessment) on membrane processes to enhance agricultural production and resource utilization
  • Advanced membrane processes for biomass conversion and management
  • Policy discussion on the application of membrane technologies to achieve circular agricultural production

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Membranes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

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. Full article
