Conveyance of Residuals from Water and Wastewater Treatment by Sludge Treatment, Utilization, Reclamation, and Disposal

By Sludge Treatment, Utilization, Reclamation, and Disposal Committee of the Environmental and Water Resources Institute of the American Society of Civil Engineers

The remedy of water and wastewater leads to the construction of residual solids that needs to be dealt with. those solids generally are focused to lessen the water content material ahead of their important use or disposal. As those solids are extra processed and dealt with, their intrinsic properties-such as viscosity, rheology, flowability, and texture-change. even though a lot as been written to explain the chemical features of those residuals, purely constrained info has been complied describing their dealing with attribute and applicable technique of shipping. the target of this handbook is to supply a reference rfile that the practitioner can use to figure out the dealing with features of residuals and to choose applicable conveyance platforms. The monograph has been prepared into 9 chapters.

Each pump has a maximum solids size identified in the pump literature. The impeller vanes are shaped to reduce the entanglement of stringy materials. Design Features. ). 88 m3/s (14,000 gal/min). The large openings in the impeller limit maximum pumping efficiencies to around 60-80%. Horizontal close-coupled and base-mounted styles are available, as well as vertical close-coupled, cantilever, and vertical shaft models. Submersible models are also available. Operational Features and Considerations.

Non-Clog Pumps "Non-clog" or "solids handling" pumps were developed for the waste treatment and other industries to pump raw sewage and other solids containing liquids. The impeller and housing are designed with large clearances that allow solids to pass through (Figure 4-1). Each pump has a maximum solids size identified in the pump literature. The impeller vanes are shaped to reduce the entanglement of stringy materials. Design Features. ). 88 m3/s (14,000 gal/min). The large openings in the impeller limit maximum pumping efficiencies to around 60-80%.

The major axis ranges from 5 to 50 jam for unconditioned aluminum hydroxide residuals and from 5 to 100 jim for residuals conditioned with polymer.
