Filtration refers to the art practice of separating fluid from solids by use of a filter which retain the solid particles and allow the fluid to flow. Filtration process occurs both naturally and in human engineered processes. There are different methods of filtration depending on the nature of the substances to be separated and also the desired results. These methods include general filtration, hot filtration, cold filtration and vacuum filtration. The two main filter media are the surface filter and the depth filter. The surface filter technically acts as a sieve and traps the solid particles without a filter paper while depth filter normally utilizes granular material such as sand to retain bigger solid particles as the solid passes through. It is important to take note of the difference in pressure of the fluid as this is what determines how quick the filtration pressure will be. The difference in pressure can be achieved by simply observing the law of gravity or by applying air pressure on the feed side and creating a vacuum on the filtrate side. Filtration process requires maintained balance between the inflow and outflow rate of the filtrate to avoid clogging the whole system. The effectiveness of the filtration process is determined by how well the whole system is maintained. Filtration assay plates process has been successfully applied in water treatment plants to remove the solid particles present in water. Filtration is the only method through which one can separate two solid chemicals by using a solvent to dissolve one chemical, leaving the other intact in its solid state and using a filter to separate them. Oil and gas industries also utilize the filtration process to remove impurities from gas and oils after mining.
Filtration process is also utilized by many industries to cut down production costs by recycling water which is only effective after filtering. Engineers have come up with various machines such as vacuum cleaners, air conditioners and belt filters used in mining which basically utilize filtration process for them to be effective. Kitchenware equipments such as coffee makers and blenders also apply science which is based on filtration process.

Filtration can be used as a solid bottom assay plates process for pharmaceutical products where it destroys the microorganisms without altering the components of the product. Filtration process is cost effective and should be the method to consider in all units of industrial production where it is applicable.
