Sketch of a Thickener Showing the Access Bridge, Feed Well, Rakes Supported by the Central Column and Cables and the Underflow Discharge. The feed well is concentric with the rake driving shaft. The rakes are bolted or welded on to this drive shaft and for long and large rakes they have additional support from cables.
Internal support columns are not less than 8 x 8 inches (200 x 200 mm). Which of the following is a characteristic of post and beam framing? Posts and beams create square or rectangular shapes that must be braced using diagonal bracing or the use of wall panels.
A circular-tank gravity thickener having a central rotating feedwell is provided with a skimmer which is entirely supported by and rotates with the feedwell so that the rotating scraper mechanism may be elevated independently in a conventional manner.

The Detailed Design Study on HCMC Water Environment Improvement Project Final Report Main : Volume 2 8-5 Phase I is estimated at 108.5 m3/m2/day, if one (1) train of PST will be constructed in Phase I. This is little higher than the design standard of 100 m3/m2/day, which is defined from the result of wastewater treatment experiment works (WTEW), but it is still in the
For bridge and column type thickeners with tanks that are mounted on ground level the access to the slurry pumps is trough a tunnel. For very large column type thickeners the column is constructed as a caisson that is submerged in the slurry so that the pumps are housed at the bottom of the chamber and deliver the underflow upwards.
for conventional design. However, the arrangement of the foundations below the load bearing walls will be different to those normally adopted for a column and beam structural system. The desirable arrangement should provide a relatively uniform support along the length of the wall and minimize the eccentricity effects
access bridge which attaches to the rake arms. This configuration provides the most economical approach to mechanism construction for large-diameter units. A center column and pivot bearing support the cage and rake arms at the center of the tank. The AltaFlo™ is a rakeless thickener that uses rapid. Get More
Thickener Mechanism The mechanism consists of the bridge, drive and ancillaries, lifting device, feedwell, torque tube and rake arms with blades. Bridge Bridge designs are available in a truss type or castellated beam, based on the application, thickener diameter and location. The MIP designs consider not only the customer's

Based on these limiting unit areas and the feed rate of 25 t/h (dry solids) to the thickener and considering a safety factor of 1.25, the diameters of the required thickeners were calculated to be 18.8 and 16.7 m for the decantation and conventional procedures, respectively. Note that the limiting unit area was determined here solely by looking ...
