Ammonium removal using ANAMMOX process and characterization of the population

Atıksuların alıcı ortama deşarjında özellikle azot bileşenleri için getirilen sıkı standartlar mevcut sistemlerin yerine alternatif yöntemlerin geliştirilmesini gerektirmektedir. Anaerobik amonyum oksidasyonu (Anammox), özellikle yüksek azot yüküne sahip atıksuların arıtılmasında yeni ve güçlü bir sistem olarak ortaya konmuştur. Bu çalışmada tam karışımlı sürekli bir anammox reaktöründe yüksek konsantrasyonda amonyum içeren sentetik atıksu kullanılarak, 262 gün boyunca amonyum giderim verimi incelenmiştir. 1. ve 262. günler arasında sisteme verilen amonyumun %90’ının ve nitritin %99’unun giderildiği görülmüştür. Reaktörden biyokütle atılmadığından, sistem kademeli olarak artırılan azot ile yüklenmiştir. Yüklemedeki bu artış sonunda hacimsel nitrit ve amonyum dönüşüm hızı ve nitrat üretim hızı artmıştır. Çalışmada anammox prosesini yürüten mikroorganizma topluluğunun FISH analizi ile karakterizasyonu yapılmıştır. Prosesi oluşturan biyokütle topluluğunun Planktomaysit türünde Anammox bakterilerinin Dokhaven-2 alt türünden oluştuğunu göstermiştir. Anahtar Kelimeler: Anammox, amonyum, Flüoresan in situ hibridizasyon (FISH).Stringent standards for nitrogen discharge necessitate the implementation of new systems for the sustainable removal of ammonium from wastewater. One of such systems is based on the process of anaerobic ammonia oxidation called as Anammox, which is a new powerful tool especially for strong nitrogenous wastewaters. In this study, continuous flow experiments were conducted in an anammox reactor with synthetic wastewater for 262 days. Between days 1 and 262, 90% ammonium and 99% nitrite removal was obtained. In this period, the average ammonium and nitrite degradation and nitrate production yielded a ratio of 1:1.31:0.18. Since almost complete biomass retention was achieved in the reactor, the nitrogen load of the reactor could be increased gradually. In this sense, increased volumetric ammonium and nitrite conversion rates were obtained. Volumetric ammonium conversion rate was increased from 0.002 to 0.28 kg NH4+-N m-3reactor day-1 and volumetric nitrite conversion rate was increased from 0.002 to 0.363 kg NO2--N m-3reactor day-1. The microbial community in the reactor was characterized with Fluorescence in situ Hybridization. Results obtained from the continuous flow experiments made possible to evaluate the process performance and dynamics of the anammox population. FISH analysis showed that the biocommunity in the reactor was dominated by Dokhaven strain of Planctomycete-like Anammox bacteria.

Innovative technologies for biological nitrogen removal; ANAMMOX and SHARON processes

Bu çalışmada ANAMMOX ve SHARON reaktörlerinde azot giderim performansı incelenmiştir. Her iki sistemin performansları farklı amonyak yükleri ve farklı hidrolik bekletme süresi gibi dinamik koşullar altında incelenmiştir. SHARON reaktörünün başlangıç periyodunu oluşturan süreçte nitrifikasyon bakterilerinin kültür zenginleştirme çalışmalarında en yüksek spesifik amonyum oksidasyon hızı 0.1 mg NH4+-N/mg UAKM.saat olarak elde edilmiştir. Kemostat reaktörde çamur yaşı 1.15 gün ve reaktör sıcaklığı 35±2oC olarak gerçekleştirilen işletme koşullarında kısmi nitrifikasyona ulaşılmış ve işletme boyunca ortalama %90 amonyum azotu giderim verimi ile 2.8 mg NH4+-N/mg UAKM.saat spesifik amonyum oksidasyon hızı elde edilmiştir. Sistem metanol ilavesi ile döngüsel anoksik-aerobik fazlarla çamur yaşı 1.5 gün olan işletme koşullarında çalıştırıldığında oluşan nitritin ortalama %25’i denitrifiye edilebilmiştir. ANAMMOX reaktörü ise tam karışımlı sürekli akımlı bir reaktörde sistemden biyokütle atılmaksızın işletilmiş ve işletme boyunca sisteme verilen amonyum azotunun %90’nın ve nitrit azotunun %99’unun giderildiği görülmüştür. Çalışmada ayrıca ANAMMOX prosesini gerçekleştiren mikroorganizma topluluğunun FISH analizi ile karakterizasyonu yapılmıştır.

Nitrate, nitrite and ammonium are important pollutants in municipal and industrial wastewaters. Conventional methods for the biological removal of these compounds involve two discrete steps namely nitrification and denitrification. Firstly, nitrification is an energy demanding process for aeration and due to low growth rate of nitrifiers, large nitrification volumes are required. Secondly, denitrification requires organic carbon as electron donor. If the carbon content in the wastewater is not sufficient, an extra carbon source has to be supplied which causes an increase of overall treatment costs. Stringent standards on disposal of treatment sludges require aerobic or anaerobic biological sludge treatment. The effluents from anaerobic sludge digesters contain high ammonium and low organic matter and they have relatively low flow rates. In wastewater treatment plants with anaerobic sludge digestion, 15-20% of the inlet nitrogen load is recycled with the return liquors from sludge dewatering. Separate treatment of this digester supernatant would significantly reduce the nitrogen load of the main stream and improve nitrogen elimination. Chemical elimination of ammonium with magnesium ?ammonium ?phosphate (MAP) precipitation or with air stripping is feasible but it seems to be more expensive than classical biological processes. Anaerobic ammonium oxidation process (Anammox) is a new low-cost alternative to conventional denitrification systems especially for sludge digestion effluents. Anaerobic ammonium oxidation is the oxidation of ammonium to dinitrogen gas with nitrite as the electron acceptor. The process is mediated by autotrophic bacteria that use CO2 as the only carbon source. Another promising process is SHARON process that is suitable for the treatment of high strength wastewaters (high in ammonia, low in organic matter concentration). The SHARON process makes use of the growth rates of ammonia and nitrite oxidizers at sufficiently high temperatures (more than 26±C). It works at a hydraulic retention time higher than the growth rate of nitrite oxidizers but lower than ammonia oxidizers (about 1 day). This process has no sludge retention thus nitrite oxidizers are not able to remain in the reactor and they are washed out. Process is operated alternating oxic and anoxic conditions with instantaneous methanol addition. If the Anammox process is combined with a preceding nitrification step, only part of the ammonium needs to be nitrified to nitrite while the Anammox process combines the remaining ammonium with the nitrite to yield dinitrogen gas and a small amount of nitrate. Consequently, complete nitrogen removal would be achieved without addition of methanol. Partial nitrification will reduce oxygen demand in the nitrification reactor and leads to a second reduction in costs. The biomass yield of the Anammox process is very low; consequently little sludge is produced. The low sludge production is the third factor that contributes to the substantially lower operation costs compared to conventional biological nitrogen removal systems. In this study, results obtained from Anammox and SHARON reactors are presented comparatively. An enriched culture of Anammox reactor was run for 262 days where high ammonium removal efficiency was observed.  Reactor was fed with increasing nitrogen loads without biomass wastage. 90% of ammonia and 99% of nitrite were converted into dinitrogen gas. Due to complete biomass retention and increased nitrogen loadings, ammonia and nitrite conversion rates were increased. Molecular examination of Anammox culture with FISH analysis showed that culture was dominated by Dokhaven-2 subclass. Ammonium oxidizers were formerly enriched in fill and draw reactors for SHARON reactor with increasing ammonium loadings. Once reliable ammonium oxidation was obtained, the culture was transferred into a chemostat and fed with higher ammonia loads. Reactor was operated with a hydraulic retention time of 0.98-1.15 days and temperature was kept about 35±2oC which is suitable for selective enrichment of ammonia oxidizers. The observed high specific ammonia oxidation rate and formation of nitrite indicated that highly active ammonia oxidizing culture was enriched. The SHARON process was established with alternating oxic and anoxic conditions with subsequent addition of methanol. In SHARON reactor only 25% of nitrite was denitrified principally due to insufficient methanol addition. Keywords: ANAMMOX, SHARON, ammonium oxidation, denitrification, Fluorescent in situ hybridization (FISH)

Severe Immune Thrombocytopenia in Pregnancy Treated with Eltrombopag. A Case Report.

Immune Thrombocytopenia (ITP) which is a common, acquired and autoimmune disease is defined as low platelet count secondary to increased platelet destruction or impaired thrombopoiesis by anti-thromboycte antibodies. Pregnancy-associated thrombocytopenia accounts for 5% of all the cases. Thrombopoietin (TPO) mimetic drugs, such as Eltrombopag, have been used successfully in many patients with ITP; however data on its use in pregnancy is limited. In this report, a case who was followed up with ITP and given Eltrombopag during her pregnancy, cause it could not have been controlled by any other treatment is presented. Enoxaparin therapy was iniatiated for thromboprophylaxis after the patient’s platelet count responded to Eltrombopag treatment. Delivery was carried out by cesarean section. Baby was born with low birth weight and there was not any malformation. Nevertheless, further research is needed to find out whether there is a relationship between Eltrombopag use in pregnancy and low birth weight

2-(1H-Benzotriazol-1-yl)-3-(2,6-dichloro­phen­yl)-1-phenyl­propan-1-ol

The asymmetric unit of the title compound, C21H17Cl2N3O, contains two crystallographically independent mol­ecules with similar conformations. The benzotriazole ring is oriented at dihedral angles of 30.61 (5) and 43.36 (5)°, respectively, to the phenyl and dichloro­phenyl rings in one mol­ecule, and 32.25 (5) and 41.04 (5)° in the other. The dihedral angles between the phenyl and dichloro­phenyl rings are 66.38 (7) and 66.14 (6)° in the two mol­ecules. An intra­molecular O—H⋯N hydrogen bond links the benzotriazole ring and phenyl­propanol unit in each mol­ecule. In the crystal, weak inter­molecular C—H⋯N hydrogen bonds link the mol­ecules into chains along the a axis. π–π stacking between the dichloro­phenyl rings [centroid–centroid distances = 3.809 (1) and 3.735 (1) Å] may further stabilize the crystal structure

“The Lolelaplap (Marshall Islands) in Us: Sailing West to East (Ralik→Ratak) to These Our Atolls (Aelon Kein Ad) Ad Jolet Jen Anij (Our Blessed Inheritance from God)”

This paper discusses the expansion of Oceania through a Marshallese indigenous lens as a focal point. It explains that decolonizing methodologies allows reclaiming of space for mental liberation and reassurement of constitutional rights. It highlights similar occurrences of decolonization practices meeting resistance in the 21st century all while strengthening the human right argument that no human deserves any less than their fellow human brothers and sisters. It argues that an indigenous imagery can only be viewed through an indigenous lens where the researches’ level of purity is retained and unfiltered. It nevertheless argues that Marshallese ethnolinguistics reveal the same cultural practices in America, Judeo-Christianity, and Oceania thus dictating the reality that “we are the same not withstanding one stays here and one there (Bedbedjin Bedbedjen, Bedbedjinma wot Kwe)”. It further explains the importance in these similarities and how Marshallese spirituality predates introduced American Judeo-Christianity despite the latter attempting to marginalize the former. It concludes by stating that Marshallese contributions on the global stage are rooted in that culture of love (IaKwe) which is echoed by the custom(s) revealing the significance of Marshallese validation academically, spiritually, economically, & socially to prevent institutionalized discrimination. This paper ends stating that the agency to know one’s self and how one should fit in the world, is a human right in itself and Marshallese are entitled to this sense of self worth through knowing thy self by thy self where real thinking takes place in one’s own mind as we all live our own lives

Shedding light on healthcare workers’ labour behaviours during the COVID-19 pandemic

The COVID-19 pandemic has had a profound effect on all spheres of the economy. One of the numerous consequences for the health system, in particular, was the disruption of flexible working and the need for its fundamental transformation. The article is intended to analyse and assess the relationships between flexible work perception (FWP), job satisfaction (JS), work-family balance (WFB) and task performance (TP) and examine this relational network cumulatively from the perspective of healthcare workers. The methodological framework of the research includes social exchange theory and the concept of human resources management. The study involved 353 staff members working for one of private medical clinics in the city of Gaziantep, Turkey. The research methods applied are purposeful sampling and online survey. Smart PLS3 statistical program was used to estimate the structural equation model by partial least squares method. The study showed that despite the mobilization of additional resources, TP of healthcare workers during the pandemic significantly decreased. We proved that FWP had a positive effect on task performance. At the same time, lack of flexible working negatively influenced job satisfaction and work-family balance of the employees. We found that poor WFB resulted in a decrease in the respondents’ JS and TP. Among the avenues for further research are using the data retrieved from public medical institutions and conducting the investigation in different cities and with varying working conditions
