  • SaniTEE: an ideal septic tank wastewater screen

    SaniTEE is an effluent wastewater screen (commonly known as an effluent filter) that reduces the gross suspended solids discharged in septic tank effluent. This helps extend the lives of drain fields, reduces clogging of orifices in effluent disposal systems, and allows use of non-solids handling effluent pumps. It is shown in Figure 1. It fits inside a standard septic tank outlet tee by dropping ...

  • Replacement of 130 ft Secondary Clarifiers at a 25 MGD wastewater treatment facility

    Challenge A municipal WWTP found that (2) of their secondary clarifiers were too rusted and corroded to properly function. A traditional clarifier refurbishment consisting of sandblasting and painting was not a viable option because one of the clarifier rake arms had recently broken due to its poor condition. The plant engineers decided that a clarifier rebuild was necessary to ensure ...

  • Examination of sludge accumulation rates and sludge characteristics for a decentralized community wastewater treatment systems with individual primary clarifier tanks located in Wardsville (Ontario, Canada)

    In conventional septic systems, settling and partial treatment via anaerobic digestion occurs in the septic tank. One of the byproducts of solids separation in the septic tank is a semi-liquid material known as septage, which must be periodically pumped out. Septage includes the liquid portion within the tank, as well as the sludge that settles at the bottom of the tank and the scum that floats ...

  • 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, ...

  • 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 ...

  • Rectangular vs. Circular Clarifiers: Which is better?

    Both rectangular and circular configurations have been commonly used in clarifier basins. The relative merits of the two have been discussed at length for decades. Historically, the selection of rectangular versus circular clarifiers has been based on past experience and the preference of the design engineer or design company. Initial wastewater treatment plant designs in the United States were ...

  • Innovative use of lamella clarifiers for central stormwater treatment in separate sewer systems

    Lamella settlers have been used in the past few years for the sedimentation of particles in wastewater and stormwater applications. A new and very innovative approach for the treatment of stormwater flows is proposed which extends the portfolio of solutions beyond traditional settling tanks. Surface runoff is stored in a sewer or a basin and finally treated in a small but continuously operated ...

  • 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 ...

  • Fracking wastewater treatment at collection facility

    Abstract Engineering company operates a wastewater collection and treatment facility for their clients in Myton, Utah. The facility receives fracking and produced wastewater from various pumping stations, and then treats the water for disposal at the injection well located on site. Electrocoagulation followed by two clarifiers and 5 micron filter was used. Since many particles float or just ...

  • 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 ...

  • Town of Manhattan Wastewater Treatment Plant

    The Manhattan treatment plant is a 400,000 GPD plant in two trains, containing six 24 x 5.0 Bio-WheelTM. It is able to nitrify and denitrify, with two anoxic basins ahead of the aeration basins. Two conventional flight and scraper clarifiers are used. Three Penn Valley RA S/MLSS pumps are located in a separate pump room. The plant is designed for a future expansion to 0.8 MGD. At this time the ...

  • Implementation of CFD modeling in the performance assessment and optimization of secondary clarifiers: the PVSC case study

    The water industry and especially the wastewater treatment sector has come under steadily increasing pressure to optimize their existing and new facilities to meet their discharge limits and reduce overall cost. Gravity separation of solids, producing clarified overflow and thickened solids underflow has long been one of the principal separation processes used in treating secondary effluent. ...

  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...
