  • What is decentralized treatment?

    Why is decentralized treatment an important solution for global water scarcity challenges? As the climate shifts and water supplies shrink due to increased use by municipalities, agriculture, and industry, the need for effective and efficient water and wastewater treatment in remote locations is growing exponentially all over the globe. In addition, the energy to power these plants and ...

  • NFPA 820 Compliance in Wastewater Treatment Plants

    Wastewater treatment plants are essential structures in cities and small communities. Such facilities are closely monitored by several professional institutions, such as OSHA and the NFPA. When it comes to the latter group, guidelines set forth in NFPA 820 are regulations that dictate fire hazards in such facilities. Fire related accidents in wastewater treatment facilities are uncommon. However, ...

  • Adapted optimization model for planning regional wastewater systems: case study

    Wastewater systems are of crucial importance to the promotion of sustainable development. Through an integrated planning approach, the costs can be minimized and the resulting benefits maximized. A planning approach at regional level exploits the economies of scale, while achieving a better environmental performance. In this paper we set out a decision support approach for the planning of ...

  • Improvement of phosphorus removal by calcium addition in the iron electrocoagulation process

    Small-scale wastewater treatment plants (SWTPs) are widely used as decentralized wastewater treatment systems in sparsely populated areas of Japan. Iron electrolysis, an electrocoagulation technology, is installed in these SWTPs for phosphorus removal. Phosphorus can be removed via the formation of an insoluble compound containing phosphate and iron, such as FePO4; however, it was necessary to ...

  • 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 ...

  • Some unique solutions to water, wastewater challenges

    Challenges are not unique to water and wastewater treatment, but the challenges thrown at operators and managers often require equal parts of thoughtfulness and creativity, with dashes of patience and persistence. This is why the industries are “home to some of the most ingenious professionals to be found in any industry,” according to an editorial in Treatment Plant Operator. ...

  • Gaussian process regression for monitoring and fault detection of wastewater treatment processes

    Monitoring and fault detection methods are increasingly important to achieve a robust and resource efficient operation of wastewater treatment plants (WWTPs). The purpose of this paper was to evaluate a promising machine learning method, Gaussian process regression (GPR), for WWTP monitoring applications. We evaluated GPR at two WWTP monitoring problems: estimate missing data in a flow rate ...

  • Survey on number and size distribution of treatment wetlands in Austria

    In Austria, 1,840 wastewater treatment plants (WWTPs) with design size >50 population equivalent (PE) serve about 95% of the population. The remaining 5% of the population live in single houses and small settlements that require on site and decentralized wastewater treatment technologies. There is no common database on small WWTPs with design size <50 PE; thus data had to be collected ...

  • Sustainability of decentralized wastewater treatment technologies

    In many Countries, small communities are required to treat wastewater discharges to increasing standards of lesser environmental impacts, but must achieve that goal at locally sustainable costs. While biological membrane treatment (membrane bio-reactors (MBRs)) is quickly becoming the industry standard for centralized wastewater treatment plants, and would also be ideally suited also for small ...

  • Investigating the interactions of decentralized and centralized wastewater heat recovery systems

    In the urban water cycle there are different sources for extracting energy. In addition to potential and chemical energy in the wastewater, thermal energy can also be recovered. Heat can be recovered from the wastewater with heat exchangers that are located decentralized and/or centralized at several locations throughout the system. It can be recovered directly at the source (e.g. in the ...
