Flexible woven metal filter media with 3D-structure

For liquid filtration at high temperatures the material of choice is often sintered metal powder (PM) type filter. Tubular elements are available in a range of alloys and with pore sizes below 1 micron. The operational life of the media can easily extend over years, and its low maintenance is a strong argument for adoption. […]

DrM Filter Testing Pilot Plants & Scale Up

In many chemical processes, the filtration step is considered a bottleneck. Therefore a properly designed filter that factors in its sizing is critical for successful plant operation. In addition to DrM’s extensive filtration experience and know-how in hundreds of different processes which DrM has acquired as a result of its 3000 filter references, DrM is […]

The role of filtration in water conservation

Water has become a scarce product in many parts of the World. Once an abundantly available resource, supply is running low and demand both for private and industrial use has constantly increased over the years. While historically we have never given too much attention to conservation of this valuable product, we today find ourselves increasingly […]

Selection of equipment for solids removal in natural gas extraction operations – CAPEX vs. OPEX considerations

The extraction of natural gas requires the removal of suspended solids from the feed stream. Generally, these streams can be grouped as follows: Produced Water (PW) and dirty liquid streams resulting from pipeline pigging operations Rich monoethylene glycol (MEG) recycle streams which contain various salts from the produced water. The injection of MEG at the well head […]

FUNDAMIX® Gas Injection

FUNDAMIX® Trial with size FM2 with Gasinjection through the shaft at different flows and amplitudes With the injection through the shaft (which is not possible with a rotating stirrer) a better dispersion can be reached and the solution is much cheaper as a sparger ring. Also better suitable for CIP/SIP.
