Protecting your pump against low to no-flow conditions
Pump manufacturers publish different values for minimum flows in technical publications or on performance curves, but what does it all mean, and what should pump operators do with this information? Is there a difference between minimum flow and minimum continuous stable flow (MCSF)? What happens if you pump below these stated values? And what are some ways to protect your pump against low-flow ...

Comprehensive analysis of tobacco smoke using TD–GC×GC–TOF MS with Tandem Ionisation
The hazardous constituents of cigarette smoke have attracted considerable attention lately, especially with increasing regulation around the world limiting or banning smoking in public places – and even in private cars if children are present. From an analytical perspective, however, there is much that remains to be learnt about the composition of cigarette smoke, because of its high ...

Norfolk County Council tackle groundwater contamination with low-flow - Case Study
Geotech low flow groundwater analysis equipment has enabled quick and easy access to samples at 2m intervals down a 28m screen in deep boreholes. Elizabeth Guilford of Norfolk County Council hired the low flow kit from Geotech and used it on a Norfolk CC landfill where leachate contamination of groundwater was suspected. Samples taken at 2m intervals close to elevation of the suspected ...

What is a centrifugal pump?
What is a centrifugal pump? A centrifugal pump is a mechanical device designed to move fluid by rotating energy from one or more driven rotors called impellers. The fluid enters the rapidly rotating impeller along its axis and is discharged by centrifugal force along its circumference through the blade tip of the impeller. The action of the impeller increases the velocity and pressure of the ...

Controlling the Flow Capacity of a Metering Pump
Since a metering pump is usually a positive displacement pump there are two possible ways of controlling the flow capacity. The first one is by adjusting the volume of liquid displaced per stroke of the pump and the second is by adjusting the speed of the strokes. I. Stroke Length – control the displacement volume per stroke II. Speed of Strokes per minute Stroke Length – Manual: ...

Operation of a full-scale pumped flow biofilm reactor (PFBR) under two aeration regimes
A novel technology suitable for centralised and decentralised wastewater treatment has been developed, extensively tested at laboratory-scale, and trialled at a number of sites for populations ranging from 15 to 400 population equivalents (PE). The two-reactor-tank pumped flow biofilm reactor (PFBR) is characterised by: (i) its simple construction; (ii) its ease of operation and maintenance; ...

Fluid Flow and Transport in Porous Media – Chemyx Fusion 6000 Syringe Pump Application
Nanoparticle as part of nanotechnology has already drawn attention to its great potential of enhancing oil recovery. In the last few years, some publications have already addressed this topic, but the basic enhanced oil recovery (EOR) mechanisms have not been released very clearly. A visualization flooding method (glass micromodel) will be used to investigate the EOR mechanisms of nanoparticle ...
