To prevent the solution from recrystallizing, which will happen when the temperature drops
Chemicals must be added to kill the bacteria after they have finished digesting.
The compound that you are trying to recrystallize is soluble in hot solvent but relatively insoluble in cold solvent. You also must remove an impurity that is insoluble in hot and cold solvent. The first filtration (a hot filtration) is to filter out the impurity. The second filtration (a cold filtration) is to filter out the (hopefully pure) recrystallized compound.
Chemical treatment is not typically considered a step in the three primary steps of water treatment, which are generally coagulation/flocculation, sedimentation, and filtration. Chemical treatment is often incorporated into these steps to aid in the clarification and disinfection of water.
During the filtration step of DNA extraction from a banana, substances that may be left behind in the cheesecloth filter include cell debris, proteins, lipids, carbohydrates, and other insoluble materials present in the mashed banana mixture. The DNA molecules should pass through the filter and be collected in the final liquid extract.
The process of recrystallization typically involves the dissolving of a crude solid in a recrystallization solvent by heating up the mixture. For crystallization to begin the crude solid has to dissolve completely so if it is observed that the crude solid has not completely dissolved a hot filtration step is required to separate the solids that are suspended.

The first step in making safe drinking water is filtration of solids. Filtration by layers of sand and rock reduces the level of salts in groundwater. Using filtration, we removed the precipitate from the chemical solution.
A Büchner funnel is adequate.

Rinsing filter paper with acetone helps to remove any residual water and ensures a dry surface for filtration. This step is important because acetone evaporates quickly, leaving behind a clean and dry filter paper that won't interfere with the filtration process.
