  • Investment and operating costs of municipal wastewater treatment plants in China

    The municipal wastewater treatment will continue to be intensified in China due to the economic development and the poor water quality. Within four years, the number of wastewater treatment plants has doubled. Before 2000, mostly plants without nitrogen and phosphorous removal were built. Since Chinese laws require strict effluent qualities, many plants were built with ...

  • Review of cost versus scale: water and wastewater treatment and reuse processes

    The US National Research Council recently recommended direct potable water reuse (DPR), or potable water reuse without environmental buffer, for consideration to address US water demand. However, conveyance of wastewater and water to and from centralized treatment plants consumes on average four times the energy of treatment in the USA, and centralized DPR would further require upgradient ...

  • Evaluation of Energy Conservation Measures for Wastewater Treatment Facilities

    This technical document will assist municipal utility owners and operators in finding information on cost-effective energy management and energy conservation measurers (ECMs) and technologies for reducing total energy usage in their wastewater treatment facilities.  The document presents technical and cost information about energy management and cost-effective energy conservation measurers ...

  • Development of a compact, cost effective, and energy efficient biofilm reactor for wastewater treatment and effluent reuse

    Abstract The CFIC (Continuous Flow Intermittent Cleaning) biofilm reactor has been developed. It contains highly packed biofilm carriers to a degree that little movement of the carriers occurs in the reactor during normal operation. The process has continuous inflow to the bioreactor and intermittent cleaning, which removes excess biomass from the biofilm carriers. A large void volume ...

  • Energy consumption model for wastewater treatment process control

    Wastewater treatment must satisfy discharge requirements under specified constraints and have minimal operating costs (OC). The operating results of wastewater treatment processes (WWTPs) have significantly focused on both the energy consumption (EC) and effluent quality (EQ). To reflect the relationship between the EC and EQ of WWTPs directly, an extended Elman neural network-based energy ...

  • Wastewater Treatment in Turbo Mode

    Sulzer turbocompressors type ABS HST are successful in wastewater treatment. Today, 2000 units are installed around the world—for example, in municipal plants like in the city of Sögel, Germany. Here, the turbocompressors not only reduced the operating costs but also helped the plant to cope with load fluctuations. The secret behind this success is an advanced design with proven ...

  • Upgrading of sewage treatment plant by sustainable and cost-effective separate treatment of industrial wastewater

    The Olburgen sewage treatment plant has been upgraded to improve the effluent quality by implementing a separate and dedicated treatment for industrial (potato) wastewater and reject water. The separate industrial treatment has been realized within a beneficial public-private partnership. The separate treatment of the concentrated flows of industrial wastewater and sludge treatment effluent ...

  • Microalgae as a sustainable alternative for wastewater treatment

    Thanks to the threats posed to human health and the environment, and the economic costs of its treatment, wastewater from domestic, industrial and agricultural processes has been considered a serious problem for a long time. However, a paradigm shift in the past few years has led to a new concept of wastewater, not as a problem but as a source of energy and other precious resources, including ...

  • Wastewater treatment plant Arnsberg-Wildshausen

    New Turbo Blower Reduces Costs And Energy Consumption Having exchanged a 19 year old turbo compressor for a turbo blower of the new “AT Turbo Generation 5” series, the wastewater treatment plant Arnsberg-Wildshausen is now making considerable savings, both in terms of energy and money. In Arnsberg-Wildshausen Ruhrverband (Essen) operates a biological wastewater ...

  • Cavitational technology in wastewater treatment process

    Cavitation is one such recent technique which has been found to be substantially beneficial in wastewater treatment. Cavitation can be described as formation, growth and sub-sequent collapse of cavities releasing large magnitudes of energy locally, creating conditions similar to hot spots, and also generating strong oxidizing conditions by way of ...

  • From Wastewater Treatment to Sweet Pineapples

    In wastewater treatment, ammonia that is removed from sewage used to be discharged directly to the atmosphere. Nowadays, studies have identified that ammonia emissions are of major concern to air quality. This has led to a new way of thinking. Sulzer offers modern closed-air-loop systems for wastewater treatment that transform ammonia into a common soil fertilizer. This reuse of a waste product ...

  • Operating costs for reducing total emission loads of key pollutants in municipal wastewater treatment plants in China

    Total emission load reduction of COD, NH4-N, TN, and TP is the key measure in controlling water pollution and eutrophication. Municipal wastewater treatment plants (MWWTPs) are major contributors in lowering energy consumption and reducing pollutant discharge. The flow-based operating costs have not been directly established to relate to costs of pollutant reduction based on an investigation of ...

  • Energy performance indicators of wastewater treatment: a field study with 17 Portuguese plants

    The energy costs usually represent the second largest part of the running costs of a wastewater treatment plant (WWTP). It is therefore crucial to increase the energy efficiency of these infrastructures and to implement energy management systems, where quantitative performance metrics, such as performance indicators (PIs), play a key role. This paper presents energy PIs which cover the unit ...
