Question

define filtration...?

Answer 1

Hi,
Here is the answer to your query:-

Filtration is any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass. The fluid that passes through is called the filtrate. In physical filters oversize solids in the fluid are retained and in biological filters particulates are trapped and ingested and metabolites are retained and removed. However, the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size, filter thickness and biological activity). Filtration occurs both in nature and in engineered systems; there are biological, geological, and industrial forms. For example, in animals (including humans), renal filtration removes wastes from the blood, and in water treatment and sewage treatment, undesirable constituents are removed by absorption into a biological film grown on or in the filter medium, as in slow sand filtration.

In simple words, filteration is the action or process of filtering something.

Answer 2

Explanation:

Filtration :

It is a process used to separate solid particles from a liquid with the help of a filter or pores of filter paper. The liquid which has passed through the filter is called the filtrate. Mechanical, biological and chemical are three types of filtration.

The best example of filtration is serving of tea after making it. Tea particles are removed using filter filter bags. The unwanted product remains in the bag and the liquid is in the cup.
