Publication Open Access Establishment of local wastewater-based surveillance programmes in response to the spread and infection of COVID-19-case studies from South Africa, the Netherlands, Turkey and England(2022-02-01) KOCAMEMİ, BİLGE; Tlhagale M., Liphadzi S., Bhagwan J., Naidoo V., Jonas K., van Vuuren L., Medema G., Andrews L., Been F., Ferreira M. L., et al.The COVID-19 pandemic has resulted in over 340 million infection cases (as of 21 January 2022) and more than 5.57 million deaths globally. In reaction, science, technology and innovation communities across the globe have organised themselves to contribute to national responses to COVID-19 disease. A significant contribution has been from the establishment of wastewater-based epidemiological (WBE) surveillance interventions and programmes for monitoring the spread of COVID-19 in at least 55 countries. Here, we examine and share experiences and lessons learnt in establishing such surveillance programmes. We use case studies to highlight testing methods and logistics considerations associated in scaling the implementing of such programmes in South Africa, the Netherlands, Turkey and England. The four countries were selected to represent different regions of the world and the perspective based on the considerable progress made in establishing and implementing their national WBE programmes. The selected countries also represent different climatic zones, economies, and development stages, which influence the implementation of national programmes of this nature and magnitude. In addition, the four countries\" programmes offer good experiences and lessons learnt since they are systematic, and cover extensive areas, disseminate knowledge locally and internationally and partnered with authorities (government). The programmes also strengthened working relations and partnerships between and among local and global organisations. This paper shares these experiences and lessons to encourage others in the water and public health sectors on the benefits and value of WBE in tackling SARS-CoV-2 and related future circumstances.Publication Open Access Short-Term Effects of Operating Parameters and Wastewater Constituents on the Performance of Free-cell Candidatus Brocadia and Candidatus Scalindua Anammox Enrichment(2022-10-01) KOCAMEMİ, BİLGE; KOCAMEMİ B., Dityapak D.Anammox, is a state-of-art nitrogen removal technology for domestic and industrial wastewater treatment. Anaerobic chemolithoautotrophic Anammox species are quite sensitive to operating parameters and various inorganic and organic compounds. Previous Anammox research was mainly on mixed cultures including Ca.Brocadia and/or Ca.Kuenenia species that are abundant in domestic wastewater. Little information exists about the mixed Anammox cultures including Ca.Scalindua species known as marine Anammox species that also present in WWTPs receiving sea-water infiltrated sewage, saline-rich wastewater in coastal cities and saline-rich industrial wastewater. In this study, the influence of operating parameters and organic and inorganic wastewater constituents on the performance of mixed suspended Ca.Brocadia and Ca.Scalindua Anammox enrichment was evaluated based on Specific Anammox Activity (SAA). Response surface methodology was used to model the relationship between pH, DO and temperature changes with SAA. Optimum pH and temperature were identified as 7.36 and 32.7(0)C, respectively. Short-term inhibitory (IC50) values of acetate, propionate and glucose were identified as 1000-1500, 3300 and 3600-5700 mg COD/L, respectively. NO2--N caused Anammox inhibition above 50 mg/l. IC50 values for SO42-, PO43--P and K+ were determined as 3500 mg SO42-/L, 1384 mg PO43--P/L and 2400 mg K+/L. The study provides a comprehensive insight into the tolerance of Ca.Brocadia and Ca.Scalindua enrichment against changing operational conditions and potential inhibiting compounds and facilitates optimization of operational strategies for the efficient performance of engineered Anammox systems. The findings will also contribute to future research activities that will focus on composite inhibitors and metabolic inhibition pathways.Publication Metadata only Atıksu bazlı epidemiyoloji çalışmaları ile covid-19 yayılımının incelenmesi(Tarım ve Orman Bakanlığı Türkiye Su Enstitüsü, 2022-02-01) KOCAMEMİ, BİLGE; ERKEN, ESRA; Kocamemi B., Erken E.Bu yayın, atıksu bazlı epidemiyoloji kavramını tanıtmak ve bu kapsamda SUEN koordinasyonunda ülkemiz genelinde yürütülen "Covid-19 yayılımının atıksularda SARS-CoV-2 analizleri ile takibi" çalışmalarının metodolojisi ve çalışmalar kapsamında edinilen bilgi ve tecrübeyi yerli ve yabancı uzmanlarla paylaşmak üzere hazırlanmıştır.Publication Metadata only Nationwide tracking of covid-19 spread by wastewater based epidemiology (WBE)(Ministry of Agriculture and Forestry of Republic of Turkiye -Turkish Water Institute, 2022-02-01) KOCAMEMİ, BİLGE; ERKEN, ESRA; Kocamemi B., Erken E.Publication Metadata only Atıksular ve atıksu çamurları ile covid 19 takibi: Türkiye örneği(2021-01-01) KOCAMEMİ, BİLGE; ERKEN, ESRA; Kocamemi B., Kurt H., Erken E., Saatci A.
