“…RO membranes are used to remove and recover ions from solution (Davis, 2010), including NH 4 + . RO systems have been utilized to retain NH 4 + from fertilizer manufacture effluents (Noworyta et al, 2003), landfill leachate (Kurniawan et al, 2006), tannery wastewater (De Gisi et al, 2009), mine wastewater (Häyrynen et al, 2009), and ammonia scrubber effluents (Fu et al, 2011) RO methods have also been applied for NH 4 + removal from AD effluent (Fig. 3).…”

Effective treatment and reuse of the massive quantities of agricultural and food wastes generated daily has the potential to improve the sustainability of food production systems. Anaerobic digestion (AD) is used throughout the world as a waste treatment process to convert organic waste into two main products: biogas and nutrient-rich digestate, called AD effluent. Biogas can be used as a source of renewable energy or transportation fuels, while AD effluent is traditionally applied to land as a soil amendment. However, there are economic and environmental concerns that limit widespread land application, which may lead to underutilization of AD for the treatment of agricultural and food wastes. To combat these constraints, existing and novel methods have emerged to treat or reuse AD effluent. The objective of this review is to analyze several emerging methods used for efficient treatment and reuse of AD effluent. Overall, the application of emerging technologies is limited by AD effluent composition, especially the total solid content. Some technologies, such as composting, use the solid fraction of AD effluent, while most other technologies, such as algae culture and struvite crystallization, use the liquid fraction. Therefore, dewatering of AD effluent, reuse of the liquid and solid fractions, and land application could all be combined to sustainably manage the large quantities of AD effluent produced. Issues such as pathogen regrowth and prevalence of emerging organic micro-pollutants are also discussed.

“…The main advantage of NF over RO is operation under lower pressures and higher recoveries [9]. The use of NF technology was extensively reported for water treatment processes as a sole treatment stage [8][9][10][11][12][13][14] or in combination with RO [15][16][17]. However, with respect to NO 3 À removal all of these processes, in their current development stage, are still limited by the aforementioned drawback associated with production of concentrated brines and the accompanied disposal issue.…”
