  • Global implementation of two shared socioeconomic pathways for future sanitation and wastewater flows

    Households are an important source of nutrient loading to surface water. Sewage systems without or with only primary wastewater treatment are major polluters of surface water. Future emission levels will depend on population growth, urbanisation, increases in income and investments in sanitation, sewage systems and wastewater treatment plants. This study presents the results for two possible ...

  • Reinvent the toilet: the NUS experience of building a decentralized toilet for energy, water and resource recovery

    In conventional activated sludge (CAS) treatment of sewage, the pollutants are mostly dissipated and hardly any reuse is present. This makes wastewater treatment very energy intensive and not sustainable in the future. Instead, sewage should be considered as a renewable resource, from which value can be extracted in the form of water, energy and nutrients (mostly nitrogen, N, phosphorus, P and ...

  • Removal of Microorganisms from Domestic Greywater Using a Recycling Vertical Flow Constructed Wetland (RVFCW)

    ABSTRACTThe reuse of greywater (GW) is an attractive addition to water management options. One of the major concerns limiting GW reuse is the possible presence of harmful microorganisms. In addition to total coliform organisms, enteric organisms (Salmonella, Shigella and poliovirus Type 1 Cryptosporidium, Giardia) and opportunistic pathogens ( Staphylococcus aureus and Pseudomonas aeruginosa) may ...

  • Intermittent operation of low pressure UF membranes for sewage reuse at household level

    A household-scale wastewater treatment system was operated with domestic sewage. The system could recover gardening/irrigation water from raw sewage or secondary effluent by low pressure ultrafiltration (UF). The UF membranes (surface area = 3.5 m2, pore size = 0.04 μm) were operated at constant transmembrane pressure (0.13 bar). The proposed technology was examined for ...

  • Septic Tank Treatment intended for effortless septic protection

    Septic tank system is most commonly used by inhabitants living in rural or semi-urban areas which are not thickly populated. The septic system provides on-site sewage treatment of waste materials. The septic tank system is overlooked by inhabitants because of their ignorance or unawareness of the septic system. Proper maintenance of Septic tank bacteria treatment is required for healthy plumbing ...

  • Mesophilic and thermophilic anaerobic digestion of source-sorted municipal solid waste

    A change in existing collection systems for household waste is presently in progress in many Swedish municipalities. The objective is to separate the decomposable fraction from non-biodegradable waste in order to facilitate biological treatment and recycling of nutrients. The main reason for this development is the effort to replace landfilling of nutrient-rich, wet organic waste with sustainable ...

  • Organic waste in circulation -co-operation between university, practice and society in Sweden

    A challenge for the future is to improve recirculation of organic waste, including its contents of nutrients, between urban and agricultural ecosystems. The main reason for developing recirculating systems is to conserve energy and nutrients. The aim is to enable production of high quality and quantity food and feed on a long-term basis, to develop safe and economically feasible systems, to ...

  • Water System Infrastructure – A View of Where We Are, Where We Could Go and How We Can Get There.

    This is the first of several essays that are aimed at focusing attention on water and sewer infrastructure systems. In this essay, the current state of city and regional systems are examined, the current state of the industry will be examined next, investigating some of the tools, resources and technologies that are available, today. Beyond that, the final essay in this series will look at the ...

  • Sustainable odour control in urban environments

    Abstract With an ever increasing focus on sustainability, the municipal recycling sector is increasingly locating recycling facilities in urban environments to be closer to their waste sources. The odour control industry needs to respond in providing ever more efficient odour extraction technologies to minimise any odour nuisance to their residential community neighbours. ...

  • Case study - Water accountability portable monitoring instruments solve flow rate mystery - Case Study

    The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow. The Township started by video taping all of the lines ...

  • Waste Water Treatment Processes Explained

    SUNCOAST WASTE WATER MANAGEMENT  presents  AEROBIC -verses- ANAEROBIC THE AEROBIC PROCESS There are two basic types of sewerage treatment processes, which are the Aerobic process and the Anaerobic process. Aerobic means with air or oxygen and Anaerobic (septic) means without air or oxygen. Aerobic bacteria are a higher life form and when digesting waste are utilising dissolved oxygen or air in ...

  • When is a Sewer not a Sewer

    Any Sewer is a Sewer –isn’t it? If you were to ask the average man on the street what happened to the water that left his house via the myriad of drain pipes, overflows, soil stacks, gutters, sewer pipes etc would he really know what happened to it? Do consumers actually know or understand that there are different sewers running under their feet? In an effort to control the spiralling ...

  • Analysis of trends in water quality: constructed wetlands in metropolitan Taipei

    Meandering through the most densely populated metropolitan areas of Taipei, Taiwan, the Danshui River and its tributaries have undergone the construction of 14 wetlands since 2004, as a means to improve water quality. This study was conducted to examine the functional capabilities associated with treating non-point source pollution through these riparian wetlands. Trend analysis was used to ...

  • Ecofriendly Alternative to Fight Grease Build-ups

    Grease traps or Grease interceptors capture the grease that goes down the kitchen drains. The simple fixture prevents slimy build up inside the drainpipes, which may result in choked drains and backflows. It is essential to cleanout these traps timely before the build up is too high to tackle. Properly maintained grease interceptors allow smooth operation of the drains by keeping the water ...

  • Chlorine Theory & Measurement

    Chlorine, dissolved in liquid is one of the most effective and economical semi-killers for the treatment of water to make it potable or safe to drink. Chlorine's powerful disinfectant qualities come from its ability to bond with and destroy the outer surfaces of bacteria and viruses. Drinking water chlorination is one of the most widely used methods to safeguard chinking water supplies. In ...

  • Presence and survival of fungi and clostridium Tyrobutyricum during anaerobic treatment of organic household waste

    Today the anaerobic microbial process of biogas formation is more into focus than ever. This interest is due to the fact that is offers the community means of fulfilling several obligations: treatment of organic wastes, recirculation of nutrients between urban and rural areas and production of renewable energy. Presently, several Swedish cities have built centralised biogas plants, treating ...
