Question

What is filtration ? Give two example of filtration















​

Answer 1

Answer:

Filtration is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter.

NOTE: The liquid which has passed through the filter is called the filtrate.

Two examples of filtration are:

a. Water in an aquifer is relatively pure because it has filtered through sand and permeable rock in the ground.

b. Air conditioner and many vaccum cleaners use HEPA filters to remove dust and pollen from the air.

Answer 2

The process in which solid particles in a liquid or gaseous fluid are removed is called filtration.

Explanation:

• Filtration is a physical or chemical separation technique of separating suspended solid matter from a liquid by passing it through a porous membrane, called a filter.
• The most common example is the filtration of tea. A filter or a sieve is used to separate tea leaves from the water.
• The second example is water filters or RO purifiers systems which remove unwanted particles from water.
