“…37 During the operation period, a total of 7137 C of electric charge were produced, with an average of 6.74 C d À1 L À1 . The maximum coulombic efficiency (CE) was 0.386%, which close to the values obtained by Doherty et al, 18 Fang et al, 13 and Zhou et al 32 As indicated in eqn (5), CE was closely related to the COD removal of the reactor; this was also conrmed in Fig. 4(c), where the CE curve trend is opposite that of COD removal.…”

“…The main techniques are: (i) anaerobic biological treatment technologies (e.g., biogas tanks, upow anaerobic sludge blankets (UASB), anaerobic migrating blanket reactors (AMBR)), 3 (ii) aerobic biological treatment technologies (e.g., aerobic sequencing batch reactors and activated sludge), 4 (iii) natural methods (e.g., constructed wetlands and stabilization ponds). 5 Recently, most livestock and poultry breeding farm pollution treatment systems only contained anaerobic treatment installations, such as biogas tanks. Biogas is a key energy resource in the emerging global renewable energy resource market, and biogas technology is considered crucial for the transition away from fossil fuel dependence.…”

“…The results obtained from this study showed that P. purpureum successfully reduced COD level by 71.57%, ammonia by 85.97% and colour intensity by 87.62%. Furthermore, this result is also supported by Klomjek et al (2016) with 64% and 70% removal efficiency of biological oxygen demand (BOD) and total Kjeldahl nitrogen (TKN), respectively.…”

Organic and/or heavy metal pollutants in soil and wastewater can be remediated by phytoremediation. Phytoremediation combines the disciplines of plant physiology, soil microbiology and soil chemistry. There are several ways by which plants extract, stabilize, filtrate, volatilize or degrade the contaminants. However, the effectiveness of phytoremediation relies upon the type of plant used. Pennisetum purpureum, commonly referred to as Napier grass, is one of the exceptional phytoremediators due to its rapid growth rate and ability to survive in highly contaminated soils. In the present review, the potential use and applicability of P. purpureum to remediate various contaminated areas was highlighted and comprehensively discussed, especially the five phytoremediation mechanisms involved (i.e., phytodegradation, phytoextraction, phytofiltration, phytostabilization, phytovolatilization). The application and management of P. purpureum in soil and wastewater phytoremediation were also critically presented. The coupling of phytoremediation and bioenergy is the zero-waste concept that can be applied since P. purpureum contains high lignocellulosic content that can be utilized as carbon source for biofuel production, such as ethanol and butanol.

“…Dans les deux cas, P. maximum s'est bien acclimatée aux milieux de culture, vraisemblablement à cause de sa nature physiologique. En fait, cette plante est fortement hydrophile et sa croissance nécessite des quantités importantes de matières organiques et nutritives (Muir and Jank, 2004 ;Klomjek, 2016). Toutefois, les feuilles des plantes du réacteur alimenté à un débit de 42,85 l/j d'eau usée avaient une coloration plus verte que celles des plantes du réacteur alimenté avec 32,14 l/j.…”

Les marais artificiels constituent une alternative moins coûteuse pour traiter efficacement les eaux usées dans les pays en développement. Cependant, la charge hydraulique appliquée peut affecter leur efficacité de traitement. Ainsi, dans cette étude, l'effet de la charge hydraulique sur le fonctionnement d'un marais artificiel à drainage vertical planté avec Panicum maximum (Jacq.) traitant des eaux usées domestiques a été étudié. Pour ce faire, deux charges hydrauliques d'eau usée domestique (32,14 l/j et 42,85 l/j) ont été utilisées. Le fonctionnement du marais artificiel a été négativement affecté par l'augmentation de la charge hydraulique. Cette augmentation de la charge hydraulique a amplifié le colmatage des réacteurs et a engendré la réduction de la biomasse végétale produite ainsi que celles des rendements épuratoires. Toutefois, les rendements obtenus avec 32,14 l/j d'eau usée appliquée sont relativement plus élevés (MES = 89,9 ± 5,6%, DCO = 89,3 ± 5%, NH 4 + = 80,6 ± 6,3% et PT = 60 ± 15,6%). Seuls les filtrats obtenus avec la charge hydraulique de 32,14 l/j ont des concentrations de polluants qui respectent les valeurs limites indiquées dans la réglementation des rejets d'eaux usées établie en Côte d'Ivoire. Cette charge hydraulique est bien indiquée pour le fonctionnement optimal du marais artificiel planté avec P. maximum.
