It is estimated that every 30 seconds, somewhere in the world, one worker dies as a result of exposure to toxic chemicals, pesticides, radiation and other hazardous substances.1 The effects of exposure can develop quickly or take years to develop, leaving workers vulnerable to asthmatic and allergic reactions and longer-term illnesses such as cancer and cardiovascular, respiratory and nervous ...

Therefore, in general, centrifugal pumps are suitable for pumping applications with low pressure, large flow rates, and viscosity of liquids from 0.1 to 200 cP. ...
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 conditions? Like many terms in the pump world, the meaning of “minimum ...
The reason for choosing Chemyx Fusion 6000 pump is the ultra-low flow rates it can provide. The pore volume of a glass micromodel is extremely small in order to mimic the actual pore channels in rock e.g. sandstone or shale. Normally the flooding volume of a core-flooding experiment will be several pore volumes, so the ...
Since a metering pump is usually a positive displacement pump there are two possible ways of controlling the flow capacity. ...
Comprehensive two-dimensional gas chromatography (GC×GC), when coupled with time-of-flight mass spectrometry (TOF MS), is also a powerful approach to the analysis of complex samples, improving chemical fingerprinting in areas of study as diverse as petrochemical analysis[1] and fragrance profiling.[2] In this study, we use thermal desorption (TD) for collection and analysis of whole ...
Geotech low flow groundwater analysis equipment has enabled quick and easy access to samples at 2m intervals down a 28m screen in deep boreholes. ...
Selected ahead of diaphragm metering pumps, the Qdos 30 pumps have been fully integrated into a complex process control system at the plant’s water treatment unit. ...
After setting-up at a borehole, operators lowered the low-flow bladder pump to the required depth and ran the pump using the multi-parameter Flow Cell until Electrical Conductivity had stabilised. ...
Proper selection should include a review of the following factors: duty cycle; pump rating or specifications including flow and pressure limits; and the liquid to be pumped with consideration for temperature and chemical compatibility. ...
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 ...
A. Low-Flow Purging Sampling Low-flow refers to the velocity with which water enters the pump intake and that is imparted to the formation pore water in the immediate vicinity of the well screen. ...
