  • 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 ...

  • 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 ...

  • 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 Process

    The wastewater treatment process is complex and critical to civilization. In simplest terms, wastewater is water that has been mixed with waste matter. Wastewater can be classified as domestic, municipal, or industrial based upon the source of generation. For instance, domestic wastewater comes from everyday liquid waste, including water used to flush the toilet, to shower, or to wash dishes. ...

  • 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-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • 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 ...

  • Synergistic application of advanced primary and secondary wastewater treatment systems

    Published in Water and Waste Digest membrane issue, November 2008 Miroslav Colic; Chief Scientist, Clean Water Technology Inc., Los Angeles, CA To be published in Water and Waste Digest later this year The increased regulatory pressures and demand for reused water stimulated development of several new wastewater technologies in the last decade. Advanced treatment systems are ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • Control of Wastewater Treatment Plants

    Instrumentation, control and automation (ICA) of wastewater treatment systems and sewer networks have attracted much attention since the early 1970s. The developments during the last four decades in on-line instrumentation, computer technology, process understanding and subsequent model development, and control methods have been powerful driving forces for advanced control making ICA ever more ...

  • What Is Industrial Wastewater Treatment?

    Industrial progress has helped economic and social growth to a large extent, whereas, it has also created the major problem of environmental pollution at the same time as well. Industrial pollution is one of the major concerns of industries and environment protection agencies worldwide. The technical advantages have assisted the industries to reduce water pollution to a certain level. ...

  • Wastewater Treatment for the Mining Industry

    Sustainable wastewater technologies minimize mining’s environmental footprint Mining for some minerals, including coal, has been diminishing due to increased financial, social, and environmental pressures, both in the United States and abroad. At the same time, mining for lithium and other metals — used in energy storage for electric cars, and wind and solar generation — is ...
