Critical Speed Analysis Of An Eight-Stage Centrifugal Pump

, 1985
Lecturepg. 59A critical speed and unbalance response analysis of an eight-stage centrifugal pump was performed, considering the variation of stiffness and damping coefficients with speed for both the oil firm bearings and the fluid seals (interstage ...

Microfiltration (MF) and Ultrafiltration (UF) for Sewage and Surface Water Concentration for SARS‐CoV‐2 and Other Enveloped Viruses' Detection in Wastewater‐Based Epidemiology (WBE)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT This study objective was to evaluate hollow fiber membranes for concentration of enveloped enteric viruses in sewage and surface water samples. Microfiltration (MF, 0.2 µm nominal pore size) and ultrafiltration (UF, 100 kDa molecular weight cut‐off) hollow fiber membranes were compared for the concentration of the bovine respiratory syncytial ...

The monitoring of cavitation in centrifugal pumps based on the analysis of vibro-acoustic measurements [PDF]

Cavitation in centrifugal pumps causes damages to pump components and produces high levels of vibration and noise, which not only reduces pump performance but also consumes additional energy.

Immobilization of Alginate Microbeads With Whole‐Cells Expressing Nitrilase for Continuous Nicotinic Acid Production in Chip Millireactor

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The biocatalytic production of nicotinic acid using nitrilases has emerged as a promising alternative to conventional chemical synthesis, offering improved selectivity and environmental sustainability. In this study, we developed a continuous‐flow millireactor system employing Escherichia coli cells expressing a nitrilase from Paraburkholderia

Serotype‐Tailored Midstream and Downstream Operations to Advance the Manufacturing of Adeno‐Associated Viral Vectors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Adeno‐associated viruses (AAVs) are the leading vectors for in vivo gene therapy, fueling a growing demand for scalable and robust biomanufacturing processes. Yet, the impact of cell lysis conditions on the performance of midstream and downstream unit operations across serotypes remains poorly characterized.
