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. […]


Ever since the introduction of the FUNDABAC® Filter various kinds of clamps have been applied to securely fix the filter flexible media to the FUNDABAC® filter element. The clamps come in various forms, such as plastic wedge rings, one way clamps in stainless steel and re-usable screw clamps in stainless steel, titanium and zirconium. Clearly, […]

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.
