Filtrand is a term used in filtration processes to refer to the solid material that has been separated from a liquid or gas during filtration. It typically consists of particles, sediment, or contaminants that are retained by a filter medium. The filtrand is important in various applications, including water treatment, pharmaceuticals, and food processing, as it indicates the effectiveness of the filtration process. Proper disposal or further treatment of the filtrand may be necessary depending on its composition and potential hazards.
What else can I help you with?
Why the solid need to be rinse with cold solvent?
Guessing what you meant here; if it's wrong, please clarify. Normally this is done after a filtration. The filtrand is rinsed with solvent to wash off any impurities that may be left. It's rinsed with cold solvent to minimize the amount of filtrand that dissolves.
What does filtration mean?
The filtrate is the liquid that is left after you filter something -- the liquid that is now "missing" the solid that was filtered out.For instance, if you are making drip coffee, it is the coffee beverage (the coffee grinds are called the "filtrand"). If you are removing sand from water, it is the water that is pure (again, the removed sand would be the filtrand).
