Demo of a small lab membrane filtration equipment that can be used at range of different trans membrane pressures at different crossflow flow rates.
Despite us using lavalier microphones, recording to our smart phones, the original recordings had quite a lot of irritating background sounds (e.g. hissing sounds) from other equipment and activities in the apparatus hall. These background sounds were removed using the noise reduction function in the program Audacity. Due the somewhat heavy noise reduction, sound may appear a bit muffled.
