“…Field IX Prototype The integration ion exchange recovery of wastewater NH 4 + with anaerobic pre-treatment of sanitation water was verified in a field prototype study [62]. The IX reactor contained three upflow chambers, each preceded by a downward plenum and each containing granular porous zeolite (Figure 1).…”

Solanum Tuberosum - A Promising Crop for Starvation Problem

View full text Add to dashboard Cite

This chapter presents an approach to recover nitrogen from human waste-water at local-scale for cultivation of Solanum tuberosum (potato) as food crop. Nitrogen capture is by ion exchange of ammonium (NH4+) onto zeolite, a natural low cost mineral which is available worldwide. A coupled process is described in which wastewater ammonium is sorbed to granular zeolite, biologically extracted (desorbed), and used to support Solanum tuberosum growth in fill-and-drain or irrigation cultivation. The system employs separate components to optimize conditions for ammonium sorption (anaerobic ion exchange), desorption (aerobic bioextraction), and cultivation (flexible timing of water and nitrogen supply and nutrient recycle). System architecture provides a low cost and readily implemented system for highly efficient nitrogen capture and incorporation into potato tuber. The nitrogen recycle system enables sustainable local-scale intensification of Solanum tuberosum production and enhanced food security through use of a reliable local nutrient supply. Metrics are presented for per capita tuber production, land area, and productivity. A system design is presented with a path forward for demonstration and development.

“…Ammonia release can be further enhanced by increasing the concentration of competing cations in the regenerant solution. Ca 2+ , Mg 2+ , and K + can be added to the regeneration solution to enhance the rate of NH 4 + release by IX, potentially enhancing the agricultural performance or the RNRS by providing additional macronutrients (Hedstrom, 2001;Payra and Dutta, 2003;Bernardi et al, 2015;Smith and Smith, 2016).…”

“…Nitrification is even more crucial in aquaponics systems that simultaneously cultivate plants and fish, as NH 3 is toxic to fish in concentrations as low as 1 mg/L NH 3 -N (Bernstein, 2011). The combination of zeolite-ammonium release into tap water with hydroponic plant production would thus realize a lowcost and low-footprint method for simultaneous wastewater nutrient recovery and reuse (Smith andSmith, 2016, 2017;Lin et al, 2016;Amini et al, 2017;Guaya et al, 2018).…”

Ammonia-nitrogen recovered from synthetic anaerobic membrane bioreactor (AnMBR) permeate facilitated by natural zeolite (clinoptilolite) ion exchange was released during regeneration with tap water into a recirculating, vertical hydroponic system to demonstrate a potential method for nitrogen recovery and reuse from domestic wastewater. Exhausted clinoptilolite leached ammonium into the tap water, which was then used for the hydroponic fertigation of butter crunch lettuce (Lactuca sativa) in vertical hydroponic towers. Crop mass and pigment development of lettuce grown in the zeolite desorption solution were favorable compared to the control (consisting of diluted, synthetic AnMBR permeate). Nitrification occurred faster in the desorption solution compared to the control, resulting in an 11% and 19% increase in fresh and dry mass, respectively, and greater chlorophyll-a and chlorophyll-b development. A system is proposed for implementing vertical trickling hydroponic systems integrated with zeolite regeneration to realize a reusable nutrient recovery system. This work demonstrates the potential of the proposed nutrient recovery system to simultaneously attenuate AnMBR ammonia-nitrogen content, while providing a renewable source of nitrogen for use in soilless agriculture.

“…Tomato fruits have a critical dietary role in providing folate, vitamins A, C and E; as well as antioxidants (lycopene, beta-carotene, gamma-carotene); trace elements of flavonoids; phytosterols and water-soluble vitamins important for human health [7]. To circumvent the challenge of decreasing soil nutrients and increase the production of vegetables (tomatoes) within a small land area, efforts have been exerted towards improving soil fertility and reducing expenses associated with commercial hydroponic fertilizer mix (CHFM) through the use of anaerobic baffled reactor (ABR) effluents and nitrified urine concentrate (NUC) both as a source of soil nutrients and water [8,9]. Smith and Smith [9], for instance, noted that nitrogen recovered from wastewater supported a high increase in tomato (Solanum lycopersicum) plant canopy volume, flower and fruit production when compared to plants treated with commercial hydroponic fertilizer mix (CHFM) which contained N, P, K, Ca, Mg and Si.…”

Al-Hamdan, Cruise et al (2014) in Jordan noted that treatment of tomato crop using waste water facilitated and increased their fruit size by up to 2 cm in diameter, and weight up to 78.7 g in relation to those administered with potable water in their field experiment.…”

We assess the discriminative strength of three different satellite spectral settings (HyspIRI, the forthcoming Landsat 9 and Sentinel 2-MSI), in mapping tomato (Solanum lycopersicum Linnaeus) plants grown under hydroponic system, using human-excreta derived materials (HEDM), namely, anaerobic baffled reactor (ABR) effluent and nitrified urine concentrate (NUC) and commercial hydroponic fertilizer mix (CHFM) as main sources of nutrients. Simulated spectral settings of HyspIRI, Landsat 9 and Sentinel 2-MSI were resampled from spectrometric proximally sensed data. Discriminant analysis (DA) was applied in discriminating tomatoes grown under these different nutrient sources. Results showed that the simulated spectral settings of HyspIRI sensor better discriminate tomatoes grown under different fertilizer regimes when compared to Landsat 9 OLI and Sentinel-2 MSI spectral configurations. Using the DA algorithm, HyspIRI exhibited high overall accuracy (OA) of 0.99 and a kappa statistic of 0.99 whereas Landsat OLI and Sentinel-2 MSI exhibited OA of 0.94 and 0.95 and 0.79 and 0.85 kappa statistics, respectively. Simulated HyspIRI wavebands 710, 720, 690, 840, 1370 and 2110 nm, Sentinel 2-MSI bands 7 (783 nm), 6 (740 nm), 5 (705 nm) and 8a (865 nm) as well as Landsat bands 5 (865 nm), 6 (1610 nm), 7 (2200 nm) and 8 (590 nm), in order of importance, were selected as the most suitable bands for discriminating tomatoes grown under different fertilizer regimes. Overall, the performance of simulated HyspIRI, Landsat 9 OLI-2 and Sentinel-2 MSI spectral bands seem to bring new opportunities for crop monitoring.
