In water treatment plants, vacuum degassing is used to purify drinking water. Gases such as methane and hydrogen sulfide are removed, which give drinking water an unpleasant taste and smell and can be a risk to our health.Food and beverage production plants also degas the water they use to ...
Vacuum forming, the practice of drawing a sheet of heat-softened plastic film over a model to make a plastic shell copy of it, is nothing new in our community. It’s most often found in hackerspaces in the form of home made vacuum forming tables, and usually requires quite a bit of ...
This is not necessarily a negative point per se; if the biodegradability index of the solution, namely the BOD5/COD ratio, is increased to values around 0.4, then this pre-treatment would be sufficient for introducing the treated solution to a bioreactor (Moussavi and Mahmoudi, 2009; Moussavi...
Which is then evacuated by a vacuum pump. Meaning that the ambient air together with the oxygen in the air are suctioned out. When the desired vacuum level has been achieved, the packaging parts are sealed together. The packaging chamber is now aerated to atmospheric pressure. Thus, the ...
An ion-getter vacuum pump comprises an envelope having a central portion 31, Fig. 2, adapted for connection to a structure to be evacuated and a portion surrounding and extending outwardly from the central portion and comprising two spaced wall portions 1, 3 joined at their outer edges by an...
