Flow Equalization - EPA

The primary objective of flow-equalization basins for municipal wastewater plants is simply to dampen the diurnal flow variation, and thus achieve a constant or nearly constant flow rate through the downstream treatment processes. A desirable secondary objective is to dampen the concentration and mass flow of wastewater constituents by blending

Choosing the Right Water Storage for Your Community | HR

Tank Mixers – Storage tanks can experience pockets of stagnant water based on a number of factors, including overall tank size/volume, demand/flow in and out of the tank, and the configuration of inlet/outlet pipes. For example, standpipes and water towers that float directly on the distribution system quite often have a single inlet/outlet

Mixing (process engineering) - Wikipedia

In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous.Familiar examples include pumping of the water in a swimming pool to homogenize the water temperature, and the stirring of pancake batter to eliminate lumps (deagglomeration).. Mixing is performed to allow …

Minimum Fall for Sewer Pipe - CivilWeb Spreadsheets

Gravitational Constant (g) (m/s 2) This is the acceleration due to gravity, typically taken as 9.81m/s 2 at sea level. Pipe Diameter (D) Concentration of Sediments (C v) This is the concentration of sediments in the flow so can be derived from the volume of sediments divided by the volume of water.

What is Mixing and Blending? What are Mixers, Blenders, or

Jul 10, 2009 · Moreover, some materials exhibit Non-Newtonian behavior. A non-Newtonian fluid is a fluid whose flow properties are not described by a single constant value of viscosity. Therefore mixing of such material requires special heavy duty mixers. These include: · Double Arm Mixers · Planetary Mixers · Dual and Triple Shaft Mixers

Concrete Mixing Methods and Concrete Mixers: State of the Art

Apr 01, 2001 · 2.1.2 Pan Mixers . All pan mixers work on basically the same principle []: a cylindrical pan (fixed or rotating) contains the concrete to be mixed, while one or two sets of blades rotate inside the pan to mix the materials and a blade scrapes the wall of the pan.The shapes of the blades and the axes of rotation vary. Figure 4 shows the different combinations …

All About Screw Conveyors (Auger Conveyors) - Types

1 day ago · Therefore, a screw-type feeder (shown above in Figure 5) is most often paired with these designs to regulate feeding flow and ensure the passage of a uniform volume of material into the conveyor. It also allows the vertical auger to remain operating at a constant speed, increasing efficiency and decreasing power consumption over time.

Wastewater Technology Fact Sheet: In-Plant Pump Stations

water level is maintained at a near constant elevation. Variable-speed pumping may allow a given flow range to be achieved with fewer pumps than would a constant-speed alternative. Variable-speed stations also minimize the number of pump starts and stops, reducing mechanical wear. Although there is a significant energy saving
