Performance of a MBR for the treatment of blackwater
The paper describes the experience gained in operating a membrane bioreactor (MBR) for the treatment of blackwater. Beside a complete characterization of blackwater, operational conditions and removal efficiency concerning parameters such as COD, BOD5, nitrogen and phosphorus as well as microbiological parameters were determined. Furthermore the membrane performance was investigated. The results ...

Particle removal in a novel sequential mechanical filter system loaded with blackwater
A novel sequential mechanical filter system was developed as an alternative primary treatment method for onsite wastewater treatment. The filter combines traditional screening with a novel type of counter-flow filter using wood-shavings as a biodegradable filter matrix. This study tested the system in a batch loading regime simulating high frequency toilet flushing using blackwater from a ...

Public perceptions of recycled water: a survey of visitors to the London 2012 Olympic Park
The Old Ford Water Recycling Plant, operated by Thames Water, was used to supply non-potable recycled blackwater to some of the venues at the London 2012 Games. In an effort to learn from this experience, Thames Water commissioned a survey of visitors to the Olympic Park during the Games to explore public responses to the water recycling project. Results show a very high level of support for ...

Application of nano-silver coated granular activated carbon for inactivation of septic tank effluent
On-site sanitation systems such as cesspools and septic tanks are widely used in most developing countries. These systems primarily aim to collect and treat toilet wastewater or blackwater. Although septic tanks are commonly used in non-sewered areas, their effluents are still rich in pathogens and other pollutants. The practice of direct discharge of septic tank effluents into the ...

Separating grey- and blackwater in urban water cycles – sensible in the view of misconnections?
The infrastructure approach SEMIZENTRAL has been developed for fast growing cities, to meet their challenges regarding water supply as well as biowaste and wastewater treatment. The world's first full-scale SEMIZENTRAL Resource Recovery Center (RRC) has been implemented in Qingdao (PR China). Greywater (GW) and blackwater (BW) are collected and treated separately. Measurement of influent ...

Semicentralized greywater and blackwater treatment for fast growing cities: how uncertain influent characteristics might affect the treatment processes
The SEMIZENTRAL infrastructure approach has been developed for fast growing cities, to meet their challenges regarding water supply as well as biowaste and wastewater (WW) treatment. The world's first full-scale SEMIZENTRAL Resource Recovery reference plant has been implemented in Qingdao (PR China). Greywater (GW) and blackwater (BW) are collected and treated separately. Measurement of ...

Design and assessment of urban drainage and water reuse systems for the reconstruction of formerly industrial areas: a case in Beijing
The Shougang Group is an industrial steel enterprise occupying 800 ha in Beijing that will cease production by 2010. The area will be converted to a new financial and commercial zone. The rebuilding of the water infrastructure in this area should address water shortages in Beijing and retain the industrial landmark of a large cooling water tank. A design framework and an assessment system with ...

Green Village Delft – integration of an autarkic water supply in a local sustainable energy system
For the Green Village at the campus of Delft University of Technology, an autarkic water circuit was developed. The aim was to avoid connections to the public water supply system, the sewerage, the electricity grid and cable systems. It should produce its own drinking water and electricity, and clean its organic waste streams in a sustainable way. Due to the strict Dutch drinking water ...

Membrane Bioreactor for Water Mining in New York City
The Facility The Helena, which opened in late 2005, is an apartment building that offers more than amenities, views, and nice finishes. Behind the $100 million tower’s gleaming glass and metal skin is a serious high-performance building. Its owner and designers say the Helena will annually use 65 percent of the energy and one-third of the potable water of comparable properties. The ...

Biomass granulation in an upflow anaerobic sludge blanket reactor treating 500 m3/day low-strength sewage and post treatment in high-rate algal pond
A pilot-scale upflow anaerobic sludge blanket-moving bed biofilm (UASB-MBB) reactor followed by a high-rate algal pond (HRAP) was designed and operated to remove organic matter, nutrients and pathogens from sewage and to facilitate reuse. For an influent chemical oxygen demand (COD) concentration of 233 ± 20 mg/L, final effluent COD was 50 ± 6 mg/L. Successful biomass granulation was observed ...

Water quality monitoring in a watershed requires easy to use field meters that are accurate and reliable.
For watershed monitoring, samples are needed from multiple locations that are typically far from each other. As traveling to remote locations is itself very time consuming, the time spent on doing the water analysis, from sample collection to getting the results, becomes even more critical. In West Virginia, some of the types of water bodies in the watershed, like blackwater rivers, possess ...
