The residuecan be driedby spreading it out on the filter paper. Missed the LibreFest? * Will suck the joy out of life. Suction filtration is preferred when the solid is retained as gravity filtration is much less efficient at removing residual liquid from the solid on the filter paper. Suction filtration is a similar process with the difference being the application of a vacuum beneath the funnel in order to pull liquid through the filter paper with suction (Figure 1.66b). and allowing the liquidtoevaporate. Ice baths are utilized to cool down the solution mixtures at a rapid rate. By the end of the post, you will realize that while undergravel filters are an ancient mode of filtration, they are very effective for biological and physical filtration.
