Electrolytic removal of ammonia from aqueous phase by Pt/Ti anode
This study investigated the mechanism and kinetic modeling of electrolytic degradation of ammonia with Pt/Ti anode. The results show that ammonia oxidation from direct oxidation or indirect oxidation with hydroxyl radicals was slow but can be observed under pH 9 and high initial ammonia concentration of 1,050 mg N L−1. Indirect oxidation with HOCl was the mechanism for the ...

Project Update - Keeping Houseboat Season Afloat
Sicamous is situated on the beautiful Shuswap Lake in the interior of British Columbia and is known as the “Houseboat Capital of Canada”. Over the years, the increase in houseboat activity on the lake has caused increased influent loading conditions (TSS, BOD5, and Total Phosphorus (TP)) at the local wastewater treatment plant. Boats unload their sewage into the collection ...

Reuse of wastewater effluent in concrete mixing and the effect of high temperatures on its residual properties
This paper investigates the suitability of using wastewater effluent for mixing in concrete. In particular, the effect of elevated temperatures up to 700°C on the compressive strength of concrete made with treated wastewater has been experimentally studied. The concrete specimens consisted of cubes that were cast using potable water (PW), primary treated wastewater (PTWW), secondary treated ...

Antimicrobial resistance of fecal indicators in disinfected wastewater
The main objective of the study was to assess the potential of three systems (UV irradiation, ozonation, and micro/ultrafiltration) operated in a pilot scale in removal of antimicrobial-resistant fecal bacteria from secondary effluent of the local wastewater treatment plant (700,000 population equivalent). The effectiveness of the processes was analysed using the removal ratio of fecal indicators ...

Resistance of
Escherichia coli andEnterococcus spp. to selected antimicrobial agents present in municipal wastewaterIn this study, the susceptibility to erythromycin (E) and to trimethoprim/sulfamethoxazole (SXT) among isolates of Enterococcus spp. and Escherichia coli was tested, respectively. Both fecal indicators were detected and isolated from raw (RW) and treated wastewater (TW) as well as from samples of activated sludge (AS) collected in a local wastewater treatment plant (WWTP). Biodiversity of ...

Use of Fecal Steroids To Infer the Sources of Fecal Indicator Bacteria in the Lower Santa Ana River Watershed, California: Sewage Is Unlikely a Significant Source
The Santa Ana River (SAR), CA and adjacent wetlands have been identified as potential sources of fecal indicator bacteria (FIB) to the surf zone at Huntington Beach, CA. A suite of fecal steroids, including coprostanol (COP), epicoprostanol (eCOP), cholesterol (CHOE), cholestanol (CHOA), R cholestanone (aONE), â-cholestanone (bONE), â-sitosterol (bSIT), stigmasterol (STIG), ...

Performance evaluation of a novel reciprocation membrane bioreactor (rMBR) for enhanced nutrient removal in wastewater treatment: a comparative study
This study compared and evaluated the performance of a conventional membrane bioreactor (MBR) and a novel reciprocation MBR (rMBR) which used mechanical membrane reciprocation in place of membrane air scouring in pilot-scale tests. Each system was independently operated for 280 days at a local wastewater treatment plant for a parallel assessment of operating performance. The rMBR was found to ...

Thurston County Comments on Pulsar Measurement Area-Velocity Flow Meters
Thurston County, Washington have been using Pulsar Measurement Greyline flowmeters for about seven years. The Stingray and the AVFM 6.1 have been used across multiple stormwater applications. Primarily their focus is to measure stormwater flow so that engineers can develop flow capacity for stormwater projects. The Stingray has been deployed in multiple locations within their stormwater ...

Impact of inocula and growth mode on the molecular microbial ecology of anaerobic ammonia oxidation (anammox) bioreactor communities. Water Research
Abstract: The composition of distinctly inoculated granular anammox and biofilm-based completely autotrophic nitrogen removal over nitrite (CANON) bioreactors was investigated from startup through continuous long-term operation via denaturing gradient gel electrophoresis (DGGE) and sequencing. The granular anammox reactor was seeded with sludge from an operational anammox reactor in Strass, ...

Rhode Island Wastewater Plants Key To Water Quality Reversal
Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort. Take, for instance, Narragansett Bay, located on the north side of the Rhode Island Sound. Located near some of America’s oldest settlements, the bay has served as a dumping ground for pollutants, ...

Intermittent feeding of wastewater in combination with alternating aeration for complete denitrification and control of filaments
In the present study, a laboratory scale system, consisting of a primary settling tank, a continuous stirred tank reactor and a clarifier were constructed and operated, using wastewater from the municipal wastewater treatment plant in Xanthi, Greece. The system operated under intermittent aeration in aerobic/anoxic conditions and feeding of the wastewater once in every cycle. The unit was ...

Local initiatives for affordable wastewater treatment (LINAW Project): Case of Dumaguete City (Public Market and Septage Treatment Plant)
Public clamor for better sanitation services had been voiced by residents and NGOs active in the area, several years ago. The same concerns have, in one instance or another, been taken up by a member of the City Council, in its deliberation of local issues. It could have been borne out of a discontinued pastime of residents in the locality ...

Simultaneous removal of nitrogen and phosphorus from wastewater by means of FeS-based autotrophic denitrification
The efficacy of iron(II) sulfide (FeS)-based autotrophic denitrification in simultaneous nitrogen and phosphorus removal from wastewater was studied with batch experiments. It was efficient at a wide pH range of 5–9, and temperature range of 10–40 °C. The concentrations of NH4+-N, Mg2+ and HCO3− in the wastewater should be kept over 7.8, 0.24 and 30 mg ...
