Combined Efficacy of Silver, Copper, and Hypochlorite Ions for Vector Control of Juvenile Aedes aegypti in Household Water Storage Containers

Sydney S. Turner, James A. Smith, Karin Brett, Patrick Illand Hancock et autres

This study evaluates the larvicidal effects of three common water disinfectants, silver (AgNO3), copper (CuSO4·5H2O), and hypochlorite (NaOCl) ions. The treatments were combined at 40–50% of their recommended drinking water guidelines and tested against late first instar and third instar Ae. aegypti …

Analyzing the Efficacy of Water Treatment Disinfectants as Vector Control: The Larvicidal Effects of Silver Nitrate, Copper Sulfate Pentahydrate, and Sodium Hypochlorite on Juvenile Aedes aegypti

Sydney S. Turner, James A. Smith, Sophie L. Howle, Patrick Illand Hancock et autres

For communities without access to uninterrupted, piped water, household water storage (HWS) practices can lead to adverse public health outcomes caused by water degradation and mosquito proliferation. With over 700,000 deaths caused by vector-borne diseases annually, the objective of this study was …

Field and Laboratory Assessment of a New Electrolytic Point-of-Use Water Treatment Technology

Courtney L. Hill, Jamie D. Harris, Sydney S. Turner, Kathryn L. Wason et autres

This research creates and implements a new electrolytic point-of-use water treatment (POUWT) device. Device development began by applying two voltages common to commercially available batteries to an apparatus with either two silver or copper wires submerged into synthetic groundwater. The effects of …

To treat or not to treat: the evolution of wastewater treatment management approaches

Sydney S. Turner

The research presented in this thesis focuses on wastewater management practices to further the understanding of the evolution of wastewater treatment approaches. Within this thesis, wastewater treatment technologies and processes are categorized into four groups: dilution dependent, conventional, alternative, and emerging. The …

Evaluation of a Silver-Embedded Ceramic Tablet as a Primary and Secondary Point-of-Use Water Purification Technology in Limpopo Province, S. Africa

Beeta Ehdaie, Chloe T. Rento, Veronica Son, Sydney S. Turner et autres

The World Health Organization (WHO) recognizes point-of-use water treatment (PoUWT) technologies as effective means to improve water quality. This paper investigates long-term performance and social acceptance of a novel PoUWT technology, a silver-infused ceramic tablet, in Limpopo Province, South Africa. When placed …
