Sludge dehydrator: common sense of the use of sewage treatment

      Sludge dehydrator: common sense of the use of sewage treatment

A.Fine water: on the basis of municipal water supply (or standard water), rough filtration, fine filtration, sterilization and other processes shall be adopted.

The quality of drinking water obtained by further processing.

B.Mineral water: the precious water resources in nature, after sterilization, filtration and simple treatment, as a commercial drinking water supply to consumers.

C.Pure water: the use of high desalination rate of water treatment equipment and almost no impurities of clean water, electrical conductivity is generally 1.0 ~ 0.1us /cm.

D.The molecular formula of water, H2O, has a relative molecular weight of 18.015. In water molecules, hydrogen accounts for 11.19% and oxygen accounts for 88.81%.

E.Salinity of water: also known as salinity, is the amount of salt in water, also can represent the sum of all kinds of anions in water.

F.Hardness: the total concentration of metal ions in water after cations combine with anions to form scale.

G.Conductivity and Resistance: The purer the water, the less salt it contains, the higher the resistivity, and the lower the conductivity.

Ultra-pure water barely conducts electricity.

The magnitude of the conductance is equal to the reciprocal of the resistance value.

The pH value of water is the negative pair value of the hydrogen ion concentration in water, also known as the hydrogen ion index.

It can be known that the aqueous solution is basic, neutral, and acidic.

H.Pure water: it refers to the water in which strong electrolytes and weak electrolytes (such as SiO2, CO, etc.) are removed or reduced to a certain extent.Its electrical conductivity is generally: 1.0 ~ 0.1US /cm, resistivity 1.0 ~ 10.0*106.cm, salt content <1mg/L.
