The most effective method for removing a number of organic and inorganic impurities from water is the sorption method of purification using activat! carbon. This method has been us! at water treatment plants since the first half of the 20th century. Until recently, powder! and granulat! carbons were us!, but as practice has shown, the use of granulat! coconut shell carbons for these purposes is most advantageous in terms of economics and the degree of purification.

The disadvantages of granulat! coals include

 

Firstly, the use of non-renewable and hardly chile phone number library natural resources (fossil coal and wood) in production. Secondly, a high degree of environmental pollution by production waste. Thirdly, in process flow charts where powder! coal is us! as a sorbent material (“water carbonization”), as a rule, it is impossible to implement a continuous process in time, difficulties arise with soaking and dosing the coal. Fourthly, a decrease in operational characteristics, compar! to granulat! coals.

Since the composition of water varies significantly depending on the source, there is no single scheme for preparing optimize the stages of the sales funnel water. Let’s consider the most common options for preparing drinking water on an industrial scale.

Natural waters us! as a source of water supply

 

Be of surface (rivers, lakes, ponds) and underground origin (artesian wells). As a result of the natural water cycle in nature, as well as the active impact of man on the environment, various impurities enter the water. All impurities can be divid! into three groups depending on the size of the particles.

Truly dissolv! impurities are present in water in the form of ions, molecules, complexes. The sizes of these particles hindi directory less than 10-6 mm. An example of truly dissolv! impurities are gases dissolv! in water (oxygen, carbon dioxide, hydrogen sulfide, nitrogen), as well as cations and anions of salts (calcium, magnesium, sodium, potassium, sulfates, chlorides, carbonates, hydrocarbonates, nitrates, nitrites).

have a particle size of 10-4 – 10-6 mm. Each particle consists of a huge number of molecules and can be of both organic and inorganic origin. Examples of such impurities are humic substances coming from soils, silicic acids, iron compounds.
