Sediment Forebay
Research has shown that energy dissipation zones in forebays with an armored bottom, a permanent pool between 2 and 18 inches deep, and a pool diameter at least as large as the influent culvert diameter is effective. Sedimentation Zone Sedimentation zones should be designed with as elongated a flow path as feasible, be shallow enough to reduce sediment settling distance, and be vegetated to ...

Analysis of the Sedimentation Characteristics of Ultrafine ...
· Due to continuous improvements in the beneficiation process, the size of tailings has decreased. In many mines, more than 50#x0025; of the total tailings are finer than 74#x2009;#x3bc;m. Ultrafine tailings exhibit a slow settling velocity and uneven settling, which pose new challenges to the safety and stability of tailings dams. In this paper, ultrafine iron tailings .

The Experimental Research on the Sedimentation Performance ...
The research shows that: lime could effectively ameliorate the noneasy sedimentation caused by sodium silie; when the dosage of sodium silie is 300～800g/t, the sedimentation performance can reach the best reasonable pH value 910. Besides, the study also indies that both sodium silie and lime are unfavorable to form sedimentation dry beach by tailings of concentrating mill.

The influence of the flocculating agent was studied in the performance (measured by microbial growth and ethanol production) of a non flocculent strain of Zymomonas mobilis, as well as the potentiality of the sedimentation process in the separation of the biomass from the fermentation broth. Among the flocculating agents studied, it was verified that both tannin and the polyelectrolyte yielded ...
