“…The gas-permeable membrane technology has been successfully applied to recover up to 99% of TAN from swine manure and anaerobically digested swine manure [5,14,[21][22][23]. Previous research mainly focused on the influence of operational conditions such as animal waste strength and pH on TAN recovery using gas-permeable membranes always operated at batch mode.…”

Gas-permeable membrane technology is a new strategy to minimize ammonia losses from manure, reducing pollution and recovering N in the form of an ammonium salt fertilizer. In this work, a new operational configuration to recover N using the gas-permeable membrane technology from swine manure was tested in a semi-continuous mode. It treated swine manure with a total ammonia nitrogen (TAN) concentration of 3451 mg L−1. The system was operated with low aeration rate (to raise pH), and with hydraulic retention times (HRT) of seven days (Period I) and five days (Period II) that provided total ammonia nitrogen loading rate (ALR) treatments of 491 and 696 mg TAN per L of reactor per day, respectively. Results showed a uniform TAN recovery rate of 27 g per m2 of membrane surface per day regardless of the ALR applied and the manure TAN concentration in the reactor. TAN removal reached 79% for Period I and 56% for Period II, with 90% of recovery by the membrane in both periods. Water capture in the acidic solution was also uniform during the experimental period. An increase in temperature of 3 °C of the acidic solution relative to the wastewater reduced 34% the osmotic distillation and water dilution of the product. These results suggested that the gas-permeable membrane technology operating in a semi-continuous mode has a great potential for TAN recovery from manure.

“…Tunes et al (2012) have reported that the presence of organic acids which originating from the anaerobic decomposition of organic material can significantly reduce the germination of wheat cultivars, radicle length and dry weight. It is well known that concentration of ammonia in digested manure is higher compared to raw manure (García-González et al 2016), which was found to reduces wheat seed germination and suppresses root hair formation (Bremner and Krogmeier 1989;Wan et al 2016). The adverse effect of combining manure with urea on seeds germination and radicle length have been reported in another study where they referred this adverse effect to the presence of ammonia, which formed through hydrolysis of urea by soil urease (Bremner and Krogmeier 1989).…”

“…This negative effect has been attributed to the contaminants that generated during decomposition of organic waste such as ethylene oxide (Wong et al 1983) and organic acid (Bacilio et al 2003;Makádi et al 2012). Moreover, the concentration of ammonia in digestate is high (García-González et al 2016) and this can reduce and delay wheat seeds germination (Bremner and Krogmeier 1989;Wan et al 2016). In fact, it is unclear if this adverse effect will last for a short or long period and thus can be avoided by adjusting the cultivation strategy, e.g.…”

Purpose This study aimed to investigate the effect of time interval between sowing and amendment with non-digested and digested poultry manure and their combinations with urea on the germination of three wheat cultivars (Slambo, Acsad, and Karim) in the desert soil. Methods The cultivars were sown on four different dates, i.e. directly, 10, 20 and 30 days after amendment. Fertilizers were applied at a rate of 350 kg Tot N ha −1. The germinated seeds were recorded daily starting at day 4 after sowing until day 14 after which the following germination attributes were calculated: time to reach 50% germination (T 50%), final germination percentage (FGP) and germination index (GI). Additionally, radicle length, plumule length and seedling dry weight were also determined. Results Sowing near to the application delayed and reduced seeds germination particularly in the treatments amended with non-digested and digested manure in combination urea. This was confirmed by all germination attributes, i.e. high values of T 50% and low values of FGP and GI. Moreover, sowing near to the application reduced the length of plumule and radicle as well as decreased seedling dry weight of all wheat cultivars. Conclusion Results suggested that prolonging the period between amendments and sowing to 20 or 30 days would give better germination attributes and increase plumule and radicle length plus increasing seedling dry weight.

“…Some technologies have been used to reduce the excess N content in livestock wastewater, promoting its recovery in the mineral form (NH + 4 ) and allowing its reuse as agricultural fertilizer in areas far from the livestock concentration with greater needs for the N nutrient. Dube et al (2016) and Garcia-Gonzalez et al (2016) used a new process utilizing gas-permeable membranes (GPM) in low pressure systems to capture the N present in the digestate from the anaerobic mono-digestion of SM and store it in a concentrated form in an acid solution of 0.5 M H 2 SO 4 .…”

“…Successful N recovery using GPM has already been performed on different organic wastes such as poultry litter (Rothrock et al, 2010(Rothrock et al, , 2013, swine manure (Garcia-Gonzalez and García-González et al, 2015) and digestate from mono-digestion of swine manure (Dube et al, 2016;Garcia-Gonzalez et al, 2016;Vanotti et al, 2017) with NH + 4 recovery above 90% of the total content of this form of the nutrient in the residues. However, recovery of N in the digestate from systems operating in ACoD has not yet been performed.…”

Anaerobic digestion of agro-industrial and livestock waste generates considerable digestate volumes that are important sources of nitrogen (N). However, on some occasions, the high concentrations of N present in the digestates may represent an obstacle to its use locally as fertilizer, since it can cause an environmental impact (European Community, 2000). This study analyzes the efficiency of gas-permeable membranes (GPM) in the recovery of the ammoniacal nitrogen (NH + 4 ) present in the swine manure (SM, Control) and three digestates generated from the anaerobic co-digestion of mixtures of SM, fruit and vegetable sludge (FVS) from the vegetable industry (peppers and artichokes), and by-products of the tomato processing industry (TW) (skins and seeds), which were mixed at three different proportions [TW + FVS]: [SM]. Their NHx + content was 2,240 mg L −1 for the SM and 4,670-5,370 for the digestate mixtures. Throughout the duration of the Necovery experiment (96 h), the percentages of NH + 4 removal and recovery achieved were consistent among treatments, approximatelly 78 and 96%, respectively. The recovery of NH 4 + for the digestate mixtures seems to be dependent on the treatment time, since the potential of N recovery was higher when the treatment time increased. However, for the control experiment (SM), with lower N concentration, the maximum N recovery was obtained at the experimental time established, without increasing the treatment time.
