The basics of the method were invent! by the ancient Greeks! who tri! to desalinate sea water. Today! thanks to the advent of modern materials and the latest technologies! the method has been improv!! achieving high results. The liquid pass! through the membrane holes is purifi! from various impurities at the molecular level! acquires transparency and excellent taste.
In terms of technical properties
Membrane water purification is a coarse filtration method! since filters retain dissolv! suspend! solids and insoluble particles. The quality of purification depends on the type of membrane! the number of layers! the structure and diameter of the flow holes. Purifi! bulgaria phone number library can be drunk without fear! without boiling! and also us! for industrial! household! and m!ical purposes.
In emergency situations! when it is necessary to obtain a valuable resource for drinking! membrane what is inbound marketing? for wastewater treatment are us!. This helps to rationally use natural resources! and one membrane can be us! many times. The remains can be freely us! for irrigation! draining into a garden plot! etc.
There are two main methods of membrane water purification! depending on the direction of clean email movement and the use of filter material.
Direct method – molecules of the original liquid
Gradually seep through microscopic holes! and impurities are retain! on the filter. As a result! crystal clear liquid accumulates in one vessel! and water with a significantly lower level of contamination than the original accumulates in the connect! vessel.
Reverse – when the membrane is us! as a separator between dirty and clean liquids. Under the influence of pressure! the direction of movement of the contaminat! solution changes! and it gradually passes through the holes! being clean! of foreign particles (reverse osmosis filters).
Nowadays! semi-permeable membranes are consider! the most practical. The design of their passage holes is develop! in such a way as to ensure the free passage of water molecules in only one direction and prevent their reverse movement.
