1. Water the suspension
suspended solids is the particle diameter above about 0.1 micron particles visible. These particles mainly composed of sediment, protozoa, bath, bacteria, viruses, and other organic polymer composition, often suspended in water, turbidity of the water generated. Suspension is the main source causing turbidity, color, odor.
2. The colloidal substances in water
water means a particle diameter of colloidal material is between 0.1 to 0.001 microns. Colloid composition is a collection of many ions and molecules, including inorganic compounds such as colloidal iron, aluminum, silicon, organic colloids such as decaying plant or animal limb and decomposition generated humins.
3. The material was dissolved in water
substance is dissolved in water of less than or equal to the diameter of the fine particles is 0.001 micrometer. Mainly water-soluble salts present to dissolve the low-molecular ions and a variety of gases.
4. The turbidity of the water
Since the water contains suspended solids and fine particles of colloidal state, so that the originally colorless, transparent turbidity in the water, its turbidity degree called turbidity. Turbidity is an expression of different sizes of water effect, different relative densities, different shapes of suspended solids, colloidal substances, plankton and microorganisms and other impurities generated light.
5. The water hardness
the concentration of other metal ions in water, such as calcium, magnesium, iron, manganese, zinc, etc., generally of iron, manganese, and zinc ions content in the water very little can be negligible. Usually put total concentration of calcium and magnesium is regarded as a hard waterdegree.
6. The water TDS value
represents the TDS content of total solids dissolved in water. Comprises dissolving salts in water, further comprising an organic material. Water into a solid dissolved solids and suspended solids. It refers to water soluble solid after filtering, various inorganic salts that remain soluble in water, organic matter and the like. Suspended solids are those insoluble in water can filter out sediment, organic matter, microorganisms and other suspended material.
7. The residual chlorine in water
Water treatment companies product after a process wherein water is added chlorine, the remainder of the water of reaction with the chlorine and the reaction collectively I chlorine, chlorine is a carcinogen.
8. Water hardness scale substances, microorganisms and the like firmly adhered rust colloid or wall where water contact.
There are water-soluble alkalinity and acidity. If they are equal, the PH of the water 7, is considered to be neutral. PH of less than 7 is acidic water. Too acidic can cause equipment corrosion, discoloration and odor.
to the PH of less than 7 water. Acidic water having a sour taste.
11. The alkalinity
is greater than the PH 7 Water state. It can be used to neutralize the acidic water. Alkaline water having a bitter taste.
12. The hard water
Water containing high levels of soluble calcium and magnesium higher level, typically found in limestone areas. Generally expressed by the number of grains per gallon of water. When heated, hard water scale is generated, it will cause problems such as a coffee maker, the ice maker and cooking equipment and other catering equipment clogging.
English brackish water, alkaline water, water hardness is greater than alkalinity, and containing large amounts of neutral salt, ph value greater than 7. Our brackish water mainly in the northern and eastern coastal areas. Rural drinking brackish water population of over 3800 people. Brackish water is mainly bitter taste is difficult to drink directly, long-term drinkingWith lead to gastrointestinal disorders, low immunity.
DO refers to dissolved oxygen in the water, which is closely related to temperature, pressure, chemical and biological action of microorganisms. At a certain temperature, can dissolve in water up to a certain amount of oxygen, for example 20 鈩? distilled water dissolved oxygen saturation value of 9.17 mg / L.
15. The suspended solids
is the number of solid matter in sewage filter can be trapped. A portion of the suspended solids under certain conditions can be precipitated. Determination of suspended solids is usually carried out by filtration with a filter layer of asbestos. Springs to water purifiers edit http://www.quanlai.net
