What is the difference between membrane distillation and pervaporation?

Answers

Answer 1

Answer: The pervaporation process is a relatively new, having common elements, reverse osmosis and gas permeation . The separating liquid mixtures by pervaporation difference in vapor pressure between the feed and the permeate. This difference in vapor pressure can be obtained in different ways: by vacuum applied to the permeate ,the most used laboratory procedure, or by cooling the permeate vapor, causing a partial vacuum, and most common industrially.The membrane destillation use heat streans to provide the evaporations. The pervaporation uses differente methods.I hope it help.

A female loggerhead turtle was fitted with a tracking device. The data showed the turtle spending all of May, June, July and August offshore of Melbourne Beach, Florida. What would be the most logical explanation for this? she was lost she was waiting for the temperatures to cool off she was mating and laying eggs she was eating a lot of algae

Answers

Well, it could possibly be, "She was maiting and laying eggs" Because,
