Abstract: Due to the heterogeneous distribution of microbial activities in a biofilter, biomass accumulation and clogging often occurs in the inlet sections, leading to a considerable increase in the total pressure drop and shortening ...

Abstract: The effects of biomass accumulation and distribution on air pressure losses in biofilters were experimentally studied. Two bench-scale biofilters, one packed with inert porous pellets (Nova Inert) and the other with wood ...

Abstract: We present a Preston tube device that combines both total and static pressure readings for the measurement of wall shear stress. As such, the device facilitates the measurement of wall shear ...

Abstract: Zebra mussels adhere tenaciously and gregariously to hard surfaces, thereby fouling water‐processing facilities and equipment. At present, there are few data on zebra mussel adhesion strength to common substrates. A rotating ...

Abstract: Copper has been used in the marine environment for decades as cladding on ships and pipes to prevent biofouling by marine mussels (
