A fluidized-pellet-bed separator with movable sludge hoppers was applied in pilot scale for the separation and thickening of activated sludge mixture liquid. Under the condition of suspension SS around 4,000 mg/L, polymer (CJX103, cationic, MW 5 × 106) dose at a dry solid ratio of 0.003 and upward flow rate at 5.4 m/hr, the fluidized pellet bed performed solid/liquid separation and sludge thick...

Failures of barrages or regulators or parts of them may be expected when excessive scour patterns are observed downstream of such structures. Severe and excessive scour may be largely due to unsymmetric operation of gates especially when a multi-vents barrages or regulator is being considered. Previous investigations proved that the scour patterns downstream hydraulic structures are functions o...

Digitization has brought the five hundred-year-old Gutenberg era to an end. Gutenberg’s press opened the gates to our modern rational, secular world. The cultural impact of today’s digital technologies, which will bring multilingual literacy to the far corners of the earth, foreshadows far greater changes. Gutenberg’s contemporaries could not begin to imagine the effect of movable type on the c...

INTRODUCTION The Cross-shore Transport Experiment (CROSSTEX) is a multi-investigator, multi-university, scientific research project centered around a coordinated series of near-prototype scale experiments that were conducted at Oregon State University's O.H. Hinsdale Wave Research Laboratory (HWRL) during the summer of 2005 (Maddux et al, 2006). The experiments took place in the 104m long, 3.7m...
