Presence of salts in water has been one of the biggest problems of industrial equipment such as evaporators, boilers, and pipes. These salts gradually form scales on evaporators and boilers tubes and reduce their efficiency. Pretreatment processes are conducted to remove these salts; with sedimentation tanks being one of the essential equipment used in these processes. This study numerically si...

Pre-sedimentation basins are among the most important elements of the conventional water treatment process. In pre-sedimentation basins, due to different velocity gradients, secondary and rotational flows are formed that will create short paths and increase dead and still flow zones as well as changes in the flow mixing. This will prevent laminar flow conditions for sedimentation and will reduc...

The modern Great Barrier Reef (GBR) is part of the world’s largest and best known mixed terrigenous-carbonate continental margin. The GBR shelf contains three shore-parallel sedimentary belts: an inner shelf zone of terrigenous sedimentation at depths of 0–22m; a middle shelf zone of sediment starvation at depths of 22–40m; and an outer shelf reef tract with its inner edge at ca. 40m depth. The...

The Brawley fault zone (BFZ) and the Brawley Seismic Zone constitute the principal transfer zone accommodating strain between the San Andreas and Imperial faults in southernmost California. The BFZ ruptured along with the Imperial fault in the 1940 Mw 6.9 and the 1979 Mw 6.4 earthquakes, although in each case only minor slip apparently occurred on the BFZ; several other episodes of slip and cre...

Abstract The origin of the passive margin forming paleo-Pacific western edge ancestral North American continent (Laurentia) constrains breakup Rodinia and sets stage for Phanerozoic evolution Laurentia. Windermere Supergroup in southern Canadian Cordillera records rift-to-drift sedimentation form a prograding continental deposited between ~730 570 Ma. New U-Pb detrital zircon analysis from samp...

sedimentation is one of the most important problems in harbors that results in considerable economic costs. harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. in the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...

Observations that the majority of silica dissolution occurs within the upper 200 m of the ocean, and that sedimentation rates of diatom frustules generally do not decrease significantly with depth, suggested reduced dissolution rates of diatoms embedded within sinking aggregates. To investigate this hypothesis, silica dissolution rates of aggregated diatom cells were compared to those of disper...

Biomass harvesting is a bottleneck in microalgae culture and microalgae-based wastewater treatment systems. Sedimentation coupled to coagulation flocculation has been experimentally studied for long time, however, full scale sedimentation experiences have not addressed so far literature, scaling up from experimental results may be straightforward. The aim of this study was evaluate the performa...

Abstract New whole-rock geochemical and detrital zircon U–Pb Lu–Hf data of metasedimentary sequences the Silvretta Nappe, Orobic Alps, Strona-Ceneri Zone, Gotthard Massif Venediger Nappe are presented. These units seem to share a common early middle Paleozoic geological record, which has alternatively been interpreted as result intraplate or orogenic processes. Detrital mainly indicate late Edi...
