  • Vortex in baffled surface aerator

    Baffled surface aerator and mixing tanks are different on the basis of the rotor placement. In mixing tanks, rotors are placed very deep in the tank, thus vortex creation can be prevented by placing the baffles. By definition, rotors are placed at or near the surface of water in surface aeration systems; complete prevention of vortex creation cannot be achieved by installing the baffles. Vortex ...

  • Tracer experiment and RTD analysis of DAF separator with bar-type baffles

    This paper describes the development of a new dissolved air flotation (DAF) separator with a flow streamlining baffle to improve solid separation efficiency. The analysis of the RTD (residence time distribution) curves indicated that the parameter θ10 (dimensionless time at which 10% of tracer has discharged) increased from 0.38 for control reactor to 0.54 for the ...

  • Does Chlorine Contact Tank Mixing Reduce Detention Time and THM Formation?

    Water and wastewater utilities can account for nearly 40 percent of a small city's energy use. By more efficiently managing its energy use, a community can significantly affect operational costs and improve its financial sustainability. Proper mixing increases detention time by adding a vertical plug-flow element to the flow of water through a chlorine contact tank. The increased detention time ...

  • Development of a flocculation sub-model for a 3-D CFD model based on rectangular settling tanks

    To assess performance and evaluate alternatives to improve the efficiency of rectangular Gould II type final settling tanks (FSTs), New York City Department of Environmental Protection and City College of NY developed a 3D computer model depicting the actual structural configuration of the tanks and the current and proposed hydraulic and solids loading rates. Fluent 6.3.26™ was the base platform ...

  • Two-phase simulations of an off-nominally operating dissolved-air flotation tank

    The flow patterns of the contaminated water and the air bubbles inside a large-scale Dissolved Air Flotation (DAF) tank were examined using CFD modelling. The DAF tank was operating off-nominally in the sense that it was supplied with bubbles larger than originally designed for. Attention was drawn to the location for air injection and the effect of having more than one-size bubbles in the tank, ...

  • Increasing Contact Time and Reducing Short - Circuiting In a Clearwell Tank - Case study

    Background In 2005 the City of Bend, Oregon's Water Division commissioned a new reservoir, known as Outback Reservoir #2, which functions as a clear well. The reservoir is welded steel above ground tank, which is 120 feet in diameter and has a maximum depth of 35.4 feet. The reservoir has a capacity of 2.9 million gallons (MG), however typical operating depth is about 26.6 feet or ...

  • Operation of a solids contact tank at low dissolved oxygen and low total suspended solids concentrations

    Solids retention time (SRT) and dissolved oxygen concentration (DO) set points were optimized at a 32 MGD trickling filter-solids contact tank system. OPTImasterTM on-line optimization software was used for set points selection. Set points were maintained automatically using SRTmaster and DOmaster - sludge age and dissolved oxygen automatic control systems. Referenced above biological system was ...

  • NEFCO, incorporated case history

    In mid-2007, the wastewater treatment plant in Monclova Mexico was faced with a dilemma. The City had just upgraded their biological treatment scheme to increase flow through their plant by 35%, from approximately 11.5 mgd to15.5 mgd. They needed to add either a fourth secondary clarifier to keep within they discharge limits of 10 ppm TSS, or improve the operation of their three existing ...

  • Freytech oil water separators in car wash applications

    Knowing that oil can get into the reclaim water, David F. Roberts, the President of Freytech Inc., recommends the use of an enhanced coalescing oil water separator. “Even trace amounts of oil in the recycled water can diminish the quality of the wash,” he said. “An ‘oil trap’ is not enough since it is simply a tank with baffled walls which does trap some of the oil ...

  • Simple protocols for assessing dissolved air flotation systems: quantification of released air, bubble density and cloud patterns

    Dissolved air flotation (DAF) systems are useful for many water treatment applications. Optimizing a DAF system can be very difficult and complicated due to a multitude of variables that contribute to effective separation. Pressure, temperature, retention time and air mixing affect the ability of the saturator to increase air solubility, while baffle heights, flow rates and recycle ratios affect ...
