“…Reed biomass (i.e. Solids reeds in equation 2) is supposed equal to 2 kg solids /m 2 for young reeds (Tanner, 1996) and 5 kg solids /m 2 for mature vegetal fed with primary sludge (Meuleman et al, 2002). The figures underline sludge reduction; both curves come off.…”

With decentralized treatment system development, a new concern emerges: the future of the septage. The aim of this paper is to assess the feasibility of septage treatment by SDRB, and to compare its efficiencies to those of activated sludge treatment in same conditions. The study took place on ten 2m² pilot-scales SDRB. Different designs and operation conditions have been tested on sludge treatment efficiency and will be presented as: (i) the top filtration layer (sand or compost), (ii) the load (from 30 to 50 kgSS/m -2 /y). After one year and half commissioning period, we focus on the results obtained at nominal loads presenting: sludge characteristic, filtration efficiency, percolate quality and sludge deposit behaviour. Although results show better filtration efficiency for activated sludge (98.4%) than for septage (87.5%), the feasibility of septage treatment with drying reed bed has been demonstrated. Sludge accumulation is about 7.9 cm/y, when fed at 50 kgSS/m -2 /y, and dry matter content of the sludge can reach 70% in summer period. The paper will present sludge characteristics, system efficiency, to finish on design and operation condition recommendations for SDRB treating septage.

Urbanized areas increasingly rely on constructed treatment wetlands (CTW) for cost 9 effective and environmentally-based wastewater treatment. Constructed treatment wetlands are 10 particularly attractive treatment options in arid urban environments where water reuse is 11 important for dealing with scarce water resources. Emergent macrophytes play an important role 12 in nutrient removal, particularly nitrogen (N) removal, in CTW. However, the role of plant 13 community composition in nutrient removal is less clear. Numerous studies have shown that 14 macrophyte species differentially affect N uptake processes (e.g.: direct plant uptake, coupled 15 nitrification-denitrification, soil accretion). However, many of these studies have been based on 16 small-scale experiments and have been carried out in mesic environments, which means that 17 their findings are difficult to extrapolate to aridland CTW systems. Our study sought to examine 18 the relationships among emergent macrophyte productivity, plant community composition, and 19 N uptake [by both the plants and the entire ecosystem] at a 42 ha CTW in arid Phoenix, Arizona, 20 USA. We quantified above-and belowground biomass bimonthly and foliar N content annually 21 for four species groups (Typha latifolia + T. domingensis., Schoenoplectus californicus + S. 22 tabernaemontani, Schoenoplectus acutus, and Schoenoplectus americanus) from July 2011 to 23 September 2013. We quantified dissolved inorganic N fluxes into and out of the system and 24 compared plant N removal to total system fluxes. Additionally, we estimated monotypic N 25 content for each to compare the system's current community composition and plant N removal to 26

Yapay sulak alanlar (YSA) evsel, endüstriyel, tarımsal nitelikli atıksular ve deponi sızıntı suları gibi çok çeşitli atıksuları arıtmak için kullanılan yeşil bir teknolojidir. YSA, geleneksel sistemler ile karşılaştırıldığında düşük enerji, kolay işletim ve bakım, düşük yatırım/işletim maliyeti, arazi estetiği, suların yeniden kullanımı ve doğal yaşam alanı olması gibi pek çok avantaja sahiptir. A R T I C L E I N F O A B S T R A C T Research ArticleReceived 01 November 2016 Accepted 12 December 2016Constructed wetlands (CWs) are a green technology that have been used to treat several types of wastewater such as domestic, industrial, agricultural wastewaters and landfill leachate. CWs have several advantages included land intensive, low energy, easy operation and maintenance, low investment/operational costs, landscape esthetics, reuse of waters, and increased wildlife habitat compared to conventional systems. CWs are alternative treatment technologies due to these properties especially for rural settlements, industries, and hotels that are remote locations from central treatment plants. Physical, chemical, and biological treatment mechanisms can employ together in CWs. In the present study, two parallel full scale horizontal subsurface flow constructed wetlands were designed to treat domestic wastewater of Kızılcaören village in Samsun, Turkey. Juncus acutus and Cortaderia selloana were selected and the removal performance of each species were evaluated. During 7 months operation, the mean removal efficiencies of Juncus acutus and Cortaderia selloana were found as 33% and 32% ; 28% and 23% for SAA, respectively. Also, the Two-way ANOVA between groups was applied to determine any difference for the removal of all parameters between the plant types and months on the mean values of pollutants removal.
