  • Membrane chemical cleaning: why is it required and how is it performed?

    Membrane fouling, defined as the accumulation of particles and organic matter at the surface or in the pores of membranes occurs during membrane filtration. Membrane fouling results in membrane performance loss, i.e. lower rejection values, lower permeate flux and higher pressure drop, which translates into higher operational cost. The extent of fouling depends on the feed quality, operating ...

  • Numerical and experimental study of the fundamental flow characteristics of a 3D gully box under drainage

    Numerical studies regarding the influence of entrapped air on the hydraulic performance of gullies are nonexistent. This is due to the lack of a model that simulates the air-entrainment phenomena and consequently the entrapped air. In this work, we used experimental data to validate an air-entrainment model that uses a Volume-of-Fluid based method to detect the interface and the Shear-stress ...

  • Modelling boundary shear stress distribution in open channels using a face recognition technique

    This paper describes a novel application of a pattern recognition technique for predicting boundary shear stress distribution in open channels. In this approach, a synthetic database of images representing normalized shear stress distributions is formed from a training data set using recurrence plot (RP) analysis. The face recognition algorithm is then employed to synthesize the RPs and ...

  • Mechanism and kinetics of biofilm growth process influenced by shear stress in sewers

    Sewer biofilms play an important role in the biotransformation of substances for methane and sulfide emission in sewer networks. The dynamic flows and the particular shear stress in sewers are the key factors determining the growth of the sewer biofilm. In this work, the development of sewer biofilm with varying shear stress is specifically investigated to gain a comprehensive understanding of ...

  • Probability distribution of turbulence in curvilinear cross section mobile bed channel

    The present study investigates the probability density functions (PDFs) of two-dimensional turbulent velocity fluctuations, Reynolds shear stress (RSS) and conditional RSSs in threshold channel obtained by using Gram–Charlier (GC) series. The GC series expansion has been used up to the moments of order four to include the skewness and kurtosis. Experiments were carried out in the curvilinear ...

  • Optimisation of micro-processes for shear-assisted solid–liquid separation in a rotatory batch flow vortex reactor

    This paper reports the study of micro-processes in a novel pre-treatment technique using a pellet forming batch flow vortex reactor of cylindrical shape that consists of axially revolving rotor plates between fixed stator plates. The suspension was first mixed with high molecular weight synthetic polymers by stirring for approximately 50 seconds and then agitated for 20 minutes. The process ...

  • Numerical analysis of hydraulic jumps using OpenFOAM

    The present paper deals with a hydraulic jump study, characterization and numerical modeling. Hydraulic jumps constitute a common phenomenon in the hydraulics of open channels that increases the shear stress on streambeds, so promoting their erosion. A three-dimensional computational fluid dynamics model is proposed to analyze hydraulic jumps in horizontal smooth rectangular prismatic open-air ...

  • The results exceeded our expectations

    After using a Lindemann scrap shear type LU 1250/15 PA 90/25 intensively for 21 years at its headquarters in ’s-Gravendeel, the Dutch firm HKS Scrap Metals found that the machine’s hydraulic system was not functioning up to par, as is inevitable with any system subject to wear and tear. As a result, production had dropped significantly – from 35 t/h to 22 t/h. The year was 2010, ...


  • Investigation on punching shear behaviour of multi–panel flat slab

    Reinforced concrete multi–panel flat slabs subjected to punching shear are investigated in this study on the basis of finite element analysis.

  • Effect of shear rate on the activity of enzymes used in hydraulic fracture cleanup of tight unconventional reservoirs

    Injection of polymeric solutions in order to propagate a fracture and carry proppants to keep the fracture open is a common practice in hydraulic fracturing of ultra–tight formations. Polymeric fluids open and extend the already existing network of fractures. Considering the low permeability of the formation, small width of the micro–fractures, and the importance of fracture cleanup during the ...

  • Selection pressure theory for aerobic granulation – an overview

    Aerobic granulation technology is an improvement over conventional activated sludge process, where cell-to-cell interactions lead to the formation of stable granules with excellent settleability. Selection pressures are the factors that can strongly influence the formation and growth of aerobic granules. Settling time and the volume exchange ratio (VER) will decide how long the bioparticles ...

  • Adaptive control of algae detachment in regulated canal networks

    Open-channel distribution networks are subject to algal developments that can induce major disturbances such as clogging of hydraulic devices (pipes, weirs, filters, flow meters). Flushes can be used as a strategy to manage these algae developments. A flush is carried out by increasing the hydraulic shear conditions using hydraulic control structures of the canal network. In response to the ...
