  • Meat Packing Wastewater Disinfection Difficulties Leads to a State of the Art Control System and Consistent Regulatory Compliance

    ABSTRACTJohn Morrell & Co. is a meat packing plant located in Sioux Falls, South Dakota. The facility also maintains a tertiary wastewater treatment facility with a direct discharge following treatment. The treatment facility had good effluent compliance history until the spring of 2001, when sporadic elevated levels of fecal coliform and infrequent spikes in chlorine residual were ...

  • The Challenge of the Future: Operating Emerging Disinfection Technologies

    ABSTRACTThe Clean Water Act (1972 and 1977) established the basis for regulating pollutant discharges into the waters of the United States. This Act contains many provisions regulating pollutant discharges and surface water quality in the United States. This act has also been modified by numerous revisions and amendments since it was enacted in 1972. The National Pollutant Discharge Elimination ...

  • Illuminating Ultraviolet Disinfection for High-Level Reuse in Florida

    Chlorine has been the mainstay of the wastewater disinfection industry for more than 100 years due to its effectiveness, low cost and availability. However, due to various problems associated with chlorine, the Hillsborough County, Florida Water Resource Services Department decided to replace the high-level reuse water chlorine gas disinfection system at the Valrico Advanced Wastewater Treatment ...

  • What is Wastewater?

    What is wastewater? Wastewater, the waste discharge that first comes to mind in any discussion of stream pollution, is the discharge of domestic wastewater, which contains a large amount of organic waste. Industry also contribute substantial amounts of organic waste, some of which comes from vegetable and fruit packing; dairy processing; meat packing; tanning; processing of poultry, ...

  • Emerging Trends In UV Disinfection For Water Treatment

    Introduction The UV disinfection industry has experienced tremendous growth over the last 20 years.  The development of new UV technologies over this period has been a perfect example of an industry investing to meet market demand – in this case demand for an effective, low cost, and environmentally friendly disinfection technology.  The acceptance of UV disinfection at water plants ...

  • Application of UV radiation or electrochemistry in conjunction with power ultrasound for the disinfection of water

    Formerly power ultrasound was not considered economically viable for water treatment on an industrial scale. This was based on calculations involving direct scale-up of power consumption in small-scale laboratory experiments. Attitudes have changed with the installation of ultrasonic devices in operational water or sewage treatment plants. This work investigates the effect of the following ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

  • Home, Sweet Wastewater Building

    How can a wastewater treatment plant embedded into a neighborhood not use much landmass and be environmentally friendly and user-friendly all at the same time? One system aims to do all of the above. Why should a wastewater treatment plant always have to look like, well, a wastewater treatment plant?  A visual trip through project files of Aqueonics Inc., based in Greenville, SC, reveals photos ...

  • Applications of ozone for modern wastewater treatment

    Modern Wastewater Treatment Plants (WWTPs) efficiently eliminate organic pollution down to Biological Oxygen Demand (BOD) and Suspended Solids (SS) values of less than 30 mg/l. However, these treated effluents still contain biologically Persistent Organic Matter (POM), characterised by a Chemical Oxygen Demand (COD) of between 50 and more than 100 mg/l. Industrial WWTP effluents have COD ...

  • Biological wastewater treatment Dalian, China

    To manage the demands set for the plant, a biological treatment with fixed bed was chosen. The water first undergoes pre-treatment by screening and grit/grease removal. Primary sedimentation is done in 4 tanks with lamellar sedimentation.   The first step in the biological treatment consists of BOD, COD and SS ...

  • Control of dangerous substances in discharges and microbiological abatement: European framework and a case study of an ozone disinfection system

    Directive 2000/60/EC requires the achievement of a ‘good chemical status’ for surface water within pre-established dates. Disinfection is needed to achieve compulsory final microbial limit values (in Italy for wastewater discharges the parameter Escherichia coli – EC – is imposed by law with a maximum limit value of 5,000 cfu/100 mL). Liquid waste and disinfection ...

  • The Hidden Dangers of Industrial Mop Water, Examining little-known threats to the environment & wastewater treatment processes

    When we think of mop water, most likely we think of our kitchen floor. In industrial plants, however, mop water could contain a toxic blend of chemicals that are mopped off the floor, and sometimes end up in our rivers, streams and municipal wastewater systems. While we consider the health of our environment, we don’t necessarily realize the hidden dangers of mop water. This article will ...

  • Biofilm Control for Industrial Waters

    Industrial operations can face a number of serious problems due to bacterial Biofilms growing in process water systems and cooling tower waters. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and ...

  • UV, a bright future for the water industry

    The use of Ultra Violet (UV) light has now become standard practice in most municipal waste water treatment processes.  Effluent is now starting to be recognised as a valuable resource, not a problem that needs to be dumped. Many waste water facilities are being renamed as water reclamation facilities, and whether the waste water is being discharged into a river, being used to irrigate ...
