  • Achieving Advanced Wastewater Treatment Standards

    Integrated Fixed-film Activated Sludge (IFAS) systems is a hybrid system consisting of both suspended and fixed biomass growth, and it is achieved by incorporating a media that support biofilms in existing aeration basin. By promoting the growth of both carbonaceous-removing and nitrifying bacteria, an integrated fixed-film activated sludge (IFAS) process can improve effluent quality without ...


  • Advanced Lagoon Treatment Technologies for Wastewater Treatment

    Lagoon-based wastewater treatment systems are popular around the world for their simplicity and cost-effectiveness. However, these systems are unable to reliably remove biochemical oxygen demand (BOD) and total suspended solids (TSS) to less than 30 mg/L or achieve nitrification during winter months in cold climates. Several innovative modifications have been developed, which have the potential ...

  • Advanced oxidation processes with coke plant wastewater treatment

    The aim of this study was to determine the most efficient method of coke wastewater treatment. This research examined two processes – advanced oxidation with Fenton and photo-Fenton reaction. It was observed that the use of ultraviolet radiation with Fenton process had a better result in removal of impurities. ...

  • Determination of the ultrasonic effectiveness in advanced wastewater treatment

    Biological treatment is the most commonly applied method for treatment of wastewaters. However, biological treatment can be inhibited by bacteriotoxic or persistent pollutants present in wastewater (Lifka et at., 2003). As a result, this technology may be incapable of reducing the levels of contaminants below which they are not considered as a potential threat to public health. Therefore, new ...

  • Immersed Membrane Technology for Advanced Wastewater Treatment & Water Reuse

    A significant segment of the North American population is unserviced by municipal wastewater systems and, with the seemingly, unending growth of residential communities, commercial complexes, industrial parks and support infrastructure, this situation is unlikely to change in the foreseeable future. Traditionally serviced by on-site wastewater treatment units, and often relying on groundwater ...


  • Removal of organic wastewater contaminants in septic systems using advanced treatment technologies

    The detection of pharmaceuticals and other organic wastewater contaminants (OWCs) in ground water and surface-water bodies has raised concerns about the possible ecological impacts of these compounds on nontarget organisms. On-site wastewater treatment systems represent a potentially significant route of entry for organic contaminants to the environment. In this study, effluent samples were ...

  • Use of Soil Filtration and UV Disinfection for Advanced Wastewater Treatment

    Abstract While guidelines exist, currently there are no federal regulations governing treatment requirements for reclaimed water. In their absence, many states have adopted California’s reclaimed water regulations, found under Title 22 of the California Code of Regulations (CCR) as well as the UV Disinfection Guidelines for Water and Water Reuse, published by the National Water Research ...

  • Combined homogeneous and heterogeneous advanced oxidation process for the treatment of tannery wastewaters

    This study investigated the practical application of combined advanced oxidation processes (AOPs), such as homogeneous TiO2 photocatalysis and heterogeneous photo-Fenton, for the treatment of tannery wastewaters. An optimization study was conducted on the photocatalytic degradation of tannery wastewaters, in order to understand the effects of different operating parameters on the degradation ...

  • Enhancing Biological Nutrient Reduction in Advanced Individual Onsite Wastewater Treatment Systems

    ABSTRACTAdvanced onsite systems need to continue to improve wastewater treatment through nutrient reduction. Some advanced onsite systems have been shown to reduce nutrients significantly. However, with modifications, these systems can reduce total inorganic nitrogen (TIN) to an even greater degree, and nitrate to levels below federal drinkingwater standards. INTRODUCTIONNitrogen compounds in ...

  • 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 ...

  • Treatment of leather industrial wastewater via combined advanced oxidation and membrane filtration

    The liming/unhairing operation is among the important processes of the leather industry. It generates large amounts of effluent that are highly loaded with organic hazard wastes. Such effluent is considered one of the most obnoxious materials in the leather industry, causing serious environmental pollution and health risks. The effluent is characterized by high concentrations of the pollution ...

  • Advanced treatment of Membrane Bioreactor (MBR) effluents for effective wastewater reclamation

    One of the two main objectives of this work is to oxidize MBR effluents with ozone/peroxide in high pH conditions in order to improve oxidation of pharmaceuticals, which could efficiently be rejected by the nanofiltration (NF) stage. The other main objective is to effectively oxidize of dissolved organic carbon (DOC) in MBR effluents in order to decrease fouling in the filtration stage. In this ...

  • Application of vibration milling for advanced wastewater treatment and excess sludge reduction

    As a new sludge reduction technology with a phosphorus removal mechanism, a vibration milling technology that uses iron balls have been applied to the wastewater treatment process. Three anaerobic–aerobic cyclic activated sludge processes: one without sludge disintegration; one disintegrated sludge by ozonation; and the other disintegrated sludge with the vibrating ball mill were compared. ...

  • An advanced oxidation process using ionized gas for wastewater treatment

    This study on removing non-degradable materials in wastewater focused primarily on advanced oxidation methods such as ozone, ozone/UV and ozone/H2O2. Wastewater treatment using an ionized gas from plasma has been actively progressing. The ionized gas involves reactive species such as O2+, O2− cluster, O radical and OH radical. Since the ionized gas method has such outstanding characteristics as ...

  • Optimizing Wastewater Treatment

    ' Growing volumes of both industrial and municipal wastewater are being discharged to surface waters but the treatment provided frequently is inadequate to protect the desired uses of the receiving waters. With limited resources in terms of both institutional capacity and finance, governments face difficult choices in optimizing their investments in municipal systems and establishing practical ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • 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.
