网页2021年6月29日 · Membrane filter presses not only offer the advantage of an extremely high degree of dewatering; they also reduce the filtration cycle time by more than 50 percent on average, depending on the suspension. This results in faster cycle and turnaround times, which lead to an increase in productivity.
网页2022年8月19日 · Choosing between a 0.22 and 0.45 filter comes down to the retention rate or particle retention that is needed for your application. A 0.22 filter is well suited for sterilization purposes. A 0.45 filter is well suited for recovering bacteria and microorganisms from samples. Finding the correct filter pore size for you and your team’s
