Anaerobic Digestion Fundamentals

Numerous methods are available to maintain digester contents in suspension including pumping from one lo ion within the tank to another. This uses an external draft tube or an external centrifugal pump. Mechanical mixing via an impeller or linear motion mechanism lo ed within the tank or gas injection are other mixing methods.

CHAPTER 6: DESIGN AND CONSTRUCTION OF SLUDGE TREATMENT Centrifugal Pumps Centrifugal pumps as in notation 3 in Table 6.5 and Figure 6.3 a for handling sludge must be of the non-clog type. They should be robust and should have easily accessible hand-holes for cleaning. Pumps of the macerator type impeller or additional cutters with a cutting ring whereby

Centrifugal pump - Wikipedia

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.

Centrifiugal Pumps Overview

Centrifugal pump Curves- Characteristics Continued….. BHP Brake Horsepower and Capacity –For the Centrifugal pump to deliver the capacity we want we must supply the pump with a certain HP. –Generally the HP increases as we increase the capacity. BHP: is the total power required by a pump to do a specified amount of work.

Centrifugal pumps - Pump Industry Magazine

Centrifugal pumps are a type of rotodynamic pump which uses a shaft-mounted impeller that rotates unidirectionally within the pump casing. These pumps can be subdivided based on the type of impeller used: Axial flow pumps Axial flow pumps sometimes also known as propeller pumps use an impeller typically driven by an electric motor with three or four vanes that direct …

Digester Mixing Fundamentals BioCycle

Usually a chopper version of a centrifugal pump is used. Mechanical mixing systems use rotating propellers to mix the digester contents. The mixer uses propellers that are either low speed larger diameter or higher speed smaller diameter.

The Classifi ion of Pumps: Centrifugal and Positive

Centrifugal pumps are best for pumping large volumes of water long distances both for clean water supply and for sewage and drainage uses. Centrifugal pump s have been developed for a wide range of uses and when classed by their internal flow characteristics include; axial radial and mixed-flow units.

Slurry Pumps and Dredge Pumps for High Solids - EDDY Pump OEM

Compared with the tolerance in a centrifugal pump the EDDY Pump easily wins. Pump Range spans 1-inch through 12-inch EDDY Pump line the tolerance ranges from 1-12 inches. This translates to a significant amount of solids and debris pass through without clogging the pump. To learn more about the technology behind our pumps continue reading Here.

Centrifugal pump selection and ten characteristics of

When centrifugal pumps are selected if several types of pumps can meet the requirements for use you should choose an economical pump that works in the high-efficiency area. Generally single pump operation is adopted and standby pumps can be set up in important positions.
