Surface water purification conventional method is introduced

In purifying water treatment system, in addition to the sewage processing, we most of the treatment of surface water is used as the running water, rural water, water, etc. , due to the water quality of natural water sources and user requirement for water quality there are varying degrees of contradiction and gap, so we must through the use of advanced water purification technology, using the feasible scientific method for water treatment, which contains many of the natural water impurities into can meet the requirements of life and production water, we have the following simple introduce some commonly used water treatment method, it mainly consists of three parts as coagulation, sedimentation, filtration, disinfection:

1. Coagulation

water clarification treatment object mainly is suspended and colloidal substances in raw water, reduce the material formed in raw water turbidity, concrete ways in the raw water into agents ( Water purifier) , make potions and raw water after full mixing and reaction ( In the coagulation process reaction pool) So that the suspended solids in the water and colloidal impurities formation of large particles flocculation body easy to precipitate, commonly known as 'alum flowers'.

2。 Precipitation

through large particles of raw water entrainment in the process of coagulation flocculation body at a certain velocity flow into the water tank, by gravity separation tank, the water than the major impurity particles sink to the bottom of the tank.

the purification process can also be done through clarification pool, clarifier is integrating reaction and precipitation process structures

3. Filter

filter mainly by quartz sand filter, activated carbon filter, filter tank is not out of the tiny particles and impurities, activated carbon filter can also be adsorption odor, color, is the important means of filters, water treatment systems, raw water by coagulation and precipitation process, greatly reduced the turbidity of water, but through the sump tank flows into the pool of precipitation water still remain some tiny impurities, by the granular filter filter material ( Such as quartz sand, anthracite, etc. ) Intercept tiny impurities in water, to further reduce the turbidity of water. When raw water with low turbidity, the pharmaceutical raw water can not pass of coagulation and precipitation process and directly into the filtering process. The clarification technology ( Coagulation, sedimentation and filtration) In addition to reduce the turbidity of raw water, at the same time to remove chromaticity, bacteria, and viruses, etc, is also quite effective. For high turbidity raw water, usually with grit chamber or pond, remove sediment particle size larger. Disinfection

when raw water after coagulation, precipitation, filtering processing, through the pipe into the clear water reserviors, must carry out disinfection and sterilization method is in chlorine gas, bleaching powder, or other disinfectant in water, used to kill the pathogenic microorganisms in the water. Also has carried out on the water by adopting the method of ozone or ultraviolet light disinfection.

in addition to the above 2 kinds of feed water treatment, and other common processing method of deodorant, in addition to flavor, in addition to iron; Softening, desalination, and in addition to salt, etc.

according to the different raw water quality and water quality requirements for processing, the processing methods may be used alone, several methods can be combined with, in order to form different processing system. In the purification of water quality, are often used in combination with several processing methods. So depending on the water quality condition and water requirement, we design the technological process and our water treatment equipment to be effective, saving, reliable, so before making a plan, we need your water quality report, so that we can do it more accurate.
