  • LEVAPOR carrier in small sewage treatment plants

    The application of LEVAPOR carrier results in advantages also in small sewage treatment plants for 4 to 20 inhabitants. In such plants subsequent immobilisation of biomass resulted in Efficient and stable nitrification even at 10-13°C, Doubling of removal rates Lower excess sludge production and Lower outlet COD ( 45 to 65 mg/L at 1,4-1,8 kgCOD/m³x day) ...

  • Sewage treatment plant

    BONO ARTES has developed an activated sludge process called BIOCLAR, which is a great technological step forwards compared to conventional methods. A large part of civil and industrial installations, especially in developing countries, is located in remote and secluded areas where there is no possibility for connection to a public sewer. On the other hand, the minimisation of the impact on the ...

  • The Rhizopur® process ten years on: a green solution for sewage treatment in small communities

    Ten years ago the Rhizopur® process was conceived in order to treat sewage from small towns. Since 1999 when the first Rhizopur® plant was commissioned, the number of facilities has been growing steadily and today there are more than fifty Rhizopur® facilities in France. This process combines three existing technologies, i.e. biofilm, infiltration/percolation and mineralisation in constructed ...

  • ON-SITE SEWAGE SYSTEMS: NEW OUTLOOK FOR DECENTRALIZED WASTEWATER TREATMENT

    As researchers analyze the soils’ ability to absorb discharge, more knowledge is gained about alternatives to septic tanks and standard drain fields that include peat filter systems, constructed wetlands and drip irrigation. ONE out of every four American households currently treat and release wastewater on their own property. Although most people assume that on-site systems are confined to rural ...


  • SBR Wastewater Treatment Provides Large Clean-up on Small Site

    One of the largest capacity wastewater treatment plants in Europe is under construction on a small plot of land at Ringsend, on Dublin Bay in Ireland. Sequencing batch reactor (SBR) technology and 100,000 diffusers from ITT Industries' Sanitarie unit was selected to meet the challenging waste treatment needs for this site. When Dublin's wastewater treatment plant was built in the 1970s, it ...


  • Design principles to achieve a robust sewage treatment process using rotating biological contactors and reed beds

    Severn Trent Water Ltd. has chosen to adopt rotating biological contactors (RBCs) and reed beds amongst other technologies for treating sewage where the population is less than 2000. The design of an RBC to achieve a fully compliant effluent can be difficult when flows are small or the system is combined and an overflow is not permissible. In addition, RBCs have been plagued by mechanical ...

  • Viltra IWOX systems engineered by DMT - The next standard in small scale wastewater treatment

    Abstract Both technology and environmental awareness drive legislation for wastewater treatment. Now, the leap from 20/30 (BOD: Biological oxygen demand, mg/l / SS: suspended solids, mg/l) to 10/10 or even 5/5 is possible due to a different design approach. For years, the sewage treatment plant market was dominated by systems from (septic) tank suppliers, but now an engineering company ...

  • Domestic wastewater treatment with a decentralized, simple technology biomass concentrator reactor

    A new type of membrane-like aerobic reactor initially designed for the degradation of hydrocarbon-derived groundwater contaminants was tested for treating domestic wastewater. The biomass concentrator reactor (BCR) consists of an enclosed, aerated tank containing a graded filtration medium with the function of solids separation, and was previously used to treat industrial wastewaters ...

  • Assessment of existing and future sewage sludge characterisation in the Gaza Strip, Palestine

    The three wastewater treatment plants in Gaza Strip, Palestine, rely on old technologies that have proved to be unable to solve the existing problems. Sludge management is not currently considered in detail in Palestine and the area will face challenges of sludge management in the near future after the construction of ongoing and planned projects in the Gaza Strip. The paper focuses on the ...

    Emil Kiessling GmbH relies on the TFR technology from Dresden (Germany) for wastewater treatment Emil Kiessling GmbH with headquarters in Georgensgmünd, Middle Franconia (Germany), is a successful cosmetics manufacturer. The product range includes natural cosmetics through to sun ...

  • Sewage pre-concentration for maximum recovery and reuse at decentralized level

    Pre-concentration of municipal wastewater by chemically enhanced primary treatment (CEPT) was studied under controlled laboratory conditions. Both iron and aluminium-based coagulants were examined at gradually increasing concentrations (0.23, 0.35, 0.70 and 1.05 mmol/L). The CEPT sludge generated from different coagulation experiments was digested in batch anaerobic reactors, while the ...

  • Special activated sludge system works well as small town`s first WWTP

    The public works superintendent and his consulting engineer here report successful operation of a special activated sludge wastewater treatment plant (WWTP) for St. Philip’s since the end of 2003, with a similar and larger plant scheduled to start up for Portugal Cove later this year. The currently operating plant, with design average flow of 7.7 liters/sec. and peak flow of 28.5 liters/sec., has ...

  • An Infrastructure Grows · Decentralized Treatment and Recycling Domestic Wastewater

    THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...


  • Trends in biosolids handling technologies: economics and environmental factors

    Changes in activated sludge technology, with a much greater focus on nutrient removal instead of removal of organics, together with relatively long sludge mean that the primary sludge stream has been lost, and the sludge produced is less degradable. At the same time with the growing importance of sustainable solutions, beneficial agricultural use is being increasingly used. This changes quality ...

  • Efficiency of Process Measurement Technology for Determining Nutrient Parameters – Yesterday, Today and Tomorrow

    Abstract The costs and benefits of process measurement instruments in sewage treatment plants were the subject of intensive debate in the 1990s. Cost-benefit studies, comparing the potential savings in energy, consumables and personnel with the additional costs of using the instruments, resulted in recommendations specifying the minimum sewage treatment plant size at which the use of such ...
