  • Long-term hygienic barrier efficiency of a compact on-site wastewater treatment system

    Received for publication September 11, 2008. The long-term use of a filter-based, on-site wastewater treatment system increases nutrient discharge to receiving waters and may reduce its hygienic barrier efficiency. The main purpose of this research was to assess the hygienic barrier efficiency and the associated health risks of an on-site system that had exceeded its 5-yr design capacity with ...

  • Compact solutions for advanced wastewater treatment aiming to recover and reuse

    The environmental pollution caused from unregulated raw sewage discharge coming from small municipalities, remote communities, small housing complexes, tourist facilities, camps, factories, harbors and other similar sources that until now was difficult to construct suitable Treatment Facilities is quite extensive in many areas and is now the time for the authorities to take action. The necessity ...

  • Performance of an ultra-compact biofilm reactor treating domestic and synthetic wastewaters

    The performance of an ultra-compact biofilm reactor (UCBR) treating domestic wastewater (DWW) collected from a local water reclamation plant; and gradually shifting to a mono-type carbon source synthetic wastewater (SWW) combined with DDW (CWW) and finally SWW; was investigated in this study. The total COD concentrations of influent DWW and CWW/SWW were 413.6 ± 80.8 mg/L and 454.9 ± 51.3 mg/L, ...

  • Towards a low complexity carbon removal model for the optimal design of compact decentralised wastewater treatment systems

    On-site decentralised wastewater treatment systems can provide a financially attractive alternative to a sewer connection in locations far from existing sewer networks. Operational problems and shortcomings in the design of these systems still occur frequently. The aim of this paper is to provide a low complexity (i.e. easy to calibrate) but still accurate mathematical model that can be used to ...

  • Pilot trial study of a compact macro-filtration membrane bioreactor process for saline wastewater treatment

    Conventional membrane bioreactor (MBR) systems have increasingly been studied in recent decades. However, their applications have been limited due to their drawbacks such as low flux, membrane fouling, and high operating cost. In this study, a compact macro-filtration MBR (MfMBR) process was developed by using a large pore size membrane to mitigate the membrane fouling problem. A pilot trial of ...

  • Performance of a biofilter system with agave fiber filter media for municipal wastewater treatment

    Agave plants grow in semi-arid regions and are used for mescal production. However, agave fiber by-products are considered waste materials. Thus, we tested agave fiber as a filter media and biofilm material carrier for removing pollutants from municipal wastewater. Three laboratory-scale biofiltration reactors were used in two trials with five hydraulic loading rates (HLRs = 0.27, 0.54, ...

  • Major Breakthrough in Wastewater Nitrogen Removal

    Working together in close collaboration, the Hollandse Eilanden en Waarden Water Authority (Zuiveringsschap Hollandse Eilanden en Waarden, ZHEW) and Paques are pleased to announce the world's first system for sustainable nitrogen removal from waste water. In May of next year, an Anammox® system will be opened in the Dokhaven waste water purification plant of ZHEW in Rotterdam. Through the ...


  • 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 ...

  • Otis, MA municipal wastewater treatment plant information

    Small and rural communities generally find it difficult to assemble the resources to develop a traditional wastewater infrastructure.  Yet, without infrastructure it is difficult to enhance property values and economic development.  Decentralized wastewater treatment systems represent a low cost, low impact and high benefit solution.  Employing modular systems whose processes are ...

  • Feasibility of UASB/trickling filter systems without final clarifiers for the treatment of domestic wastewater in small communities in Brazil

    The paper analyses the concept and performance of different configurations of compact UASB/TF systems, without the final clarification stage, in relation to the removal of organic matter. The experiments were carried out in two sets of UASB/TF systems operating without secondary clarifiers, as follows: (i) four shallow (2.50 m height) TFs, each one filled with a different packing material; and ...

  • A Submerged Attached Growth Bioreactor for Decentralized Wastewater Treatment

    ABSTRACTThe Amphidrome® process is a submerged attached growth bioreactor (SAGB) that has been used in Massachusetts, Connecticut, Rhode Island and New Jersey for decentralized wastewater treatment systems ranging in size from 440 gpd to 150,000 gpd. The two primary advantages of a SAGB are the small volume requirement and the elimination of downstream clarification. Five years of data from four ...

  • Nakanojo wastewater treatment plant case study

    "We wonder why others don't use Volute." Nakanojo town, nestled along streams in Gunma prefecture, has seven wastewater treatment plants. Among them, Nakanojo wastewater treatment plant is the biggest municipal plant serving 5000 population equivalent. Nakanojo is the municipality where "Volute", originally intended for use in industrial applications, was installed for the ...
