Diagram of simple filtration: oversize particles in the feed cannot pass through the lattice structure of the filter, while fluid and small particles pass through, becoming filtrate. Filtration is a physical separation process that separates solid matter and fluid from a mixture using a filter medium that has a complex structure through which ...
Purification in a chemical context is the physical separation of a chemical substance of interest from foreign or contaminating substances. Pure results of a successful purification process are termed isolate.
Filters use sieving, adsorption, ion exchanges, biofilms and other processes to remove unwanted substances from water. Unlike a sieve or screen, a filter can potentially remove particles much smaller than the holes through which its water passes, such as nitrates or germs like Cryptosporidium.
A filter funnel is a laboratory funnel used for separating solids from liquids via the laboratory process of filtering. [1]In order to achieve this, a cone-like shaped piece of filter paper is usually folded into a cone and placed within the funnel.
Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). This separation process is used in industry and research for purifying and concentrating macromolecular (10 3 –10 6 Da ) solutions, especially protein ...
