A review on modern filtrations and their importance in food factories air pollution and health control

Filtration is a process in which solid particles in a mixture are separated from a liquid or gas using some type of a porous medium. Generally, solids are retained on the filter while allowing the liquid or gas through. The manufacture of food products, especially those that contain few additives to control shelf life, require air quality control measures to promote the assurance that wholesome products are offered for sale. Contamination in the air such as dust, soot and microorganisms will be removed using air filters, and the addition of heating and cooling is often required to control process and packaging environments. The air handling system will control the air condition and with the use of air movement and room air change rate it is possible to optimise process room air conditions. Air handling unit design must be hygienic with good access for cleaning and maintenance. This paper reviewes modern filtration methods and their importance in food factories air pollution and health control.
