  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

  • Wastewater treatment in Ukraine

    Lviv Vodokanal collects for treatment on average 320,000 m3/day of domestic (800,000 inhabitants) and industrial wastewater. The wastewater is treated at two  Waste Water Treatment Plants (WWTPs) placed side by side some 15 km north of Lviv’s city centre. The plants have their own wastewater treatment system while the sludge treatment facilities are shared. The total design capacity of ...

  • Wastewater treatment for a municipality

    Description of the plant At first, wastewater is pre-treated by a combinated sand and fat trap before further treatment is affected by a special screen. The accruing particles are collected in anti-septic plastic bags to avoid any personal contact because of hygienic reasons. Based on the high varying hydraulic amount of wastewater, an aerated mixing and balancing reactor is ...

  • Wastewater Treatment Works

    Margate and Broadstairs, two of the principal towns in northeastern Kent, attract thousands of visitors each summer to enjoy the beaches and countryside within easy reach of London. Such popularity comes with a cost. The infrastructure serving the area needs to be developed to keep pace with the rising population and the requirements of new UK and European Union legislation. With the ...

  • 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. Here, the turbocompressors not only reduced the operating costs but also helped the plant to cope with load fluctuations. The secret behind this success is an advanced design with proven ...

  • 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 pre-treatment in a confectionery industry

    Description of the plant In a first step, wastewater accruing from the production of marzipane is cleaned by a screen. As flow and load to the plant are highly variable depending on the production process an aerated mixing and balancing reactor has been installed to equalise flow and load before final chemical pre-treatment. After adding of chemicals for precipitation and flocculation ...

  • Airlift bioreactors: Application to wastewater treatment

    After an introductory review, this paper presents a three-phase reactor fluid dynamic model that is used in the development of a generic process for upgrading existing wastewater treatment plants (WWT). The aim is to incorporate nitrification and de-nitrification without additional reactor volume. The core of the process consists of an attached growth airlift reactor (AGAR) in which a biomass ...

  • 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 ...

  • Fine screens help New Jersey wastewater treatment plant stop rag and grease problems

    A few years ago the Hammonton Wastewater Treatment Plant, located in the lush green countryside of southern New Jersey, faced continuous problems with rags, trash and plastics passing right through a rusty old bar screen and into the oxidation ditch and final clarifier.After years spent unclogging pumps, clearing out trash and untangling the UV system – plant managers decided to find a better ...

  • Application of the Morris method for screening the influential parameters of fuzzy controllers applied to wastewater treatment plants

    In this paper, we evaluate the application of a sensitivity analysis to help fine-tuning a fuzzy controller for a biological nitrogen and phosphorus removal (BNPR) plant. The Morris Screening method is proposed and evaluated as a prior step to obtain the parameter significance ranking. First, an iterative procedure has been performed in order to find out the proper repetition number of the ...

  • Radionuclides in wastewater treatment plants: monitoring of Sicilian plants

    Three Sicilian wastewater treatment plants were monitored to assess the occurrence and the behaviour of radionuclides. Two sampling campaigns (screening and long-term) were carried out during which liquid and solid samples have been analysed. It was found that 131I mostly occurred in the samples analysed during the screening campaign (43% of the analysed samples contained 131I). ...

  • Electrocoagulation Wastewater Treatment – An Application To Sustainably Reuse Textile Wastewater

    The textile industry is a water consumption intensive industry. Water is utilized for cleaning the raw material, and for the different steps in the textile dyeing process. Due to the effects of water scarcity and stricter environmental regulations, the cost of fresh water utilization has increased worldwide. In addition, the textile industry is faced with pressure by government regulators to move ...

  • CH#831 - Municipal Wastewater Treatment Plant

    Introduction The Wastewater Treatment Plant is a rotating biological contactor treatment process preceded by bar screening, grit removal and primary settling. Subsequent to the secondary treatment process, the flow stream enters a chlorine contact tank and then goes to the receiving stream. The program study was started on March 4th. The objectives were a recovery from filamentous infestation, ...

  • Microbiology: The Key to Wastewater treatment case study

    The biological treatment of wastewater relies mainly on a consortium of heterotrophic and autotrophic bacteria. The fecal bacteria that are constantly introduced into the collection system are not the optimal bacteria for degrading the contaminants present in wastewaters. The soil bacteria that are introduced through inflow and infiltration are more effective at degrading the wastes and can ...
