2 . Clarification: The clarification treatment of water is mainly suspended solids and colloidal substances in raw water, which reduces the turbidity of these substances in raw water. The specific process can be further divided into: coagulation, sedimentation and filtration. Welcome to the company's official website http://
2 . 1 coagulation : the agent (purifying agent) is put into the raw water, so that the agent and the raw water are thoroughly mixed and reacted (that is, the coagulation process is carried out in the reaction tank), so that the suspended matter and colloidal impurities in the water form large particles flocculation which is easy to precipitate. Body, commonly known as " 矾花 " .
2 . 2 Precipitation : The raw water entrained by the coagulation process entrains large particle flocs into the sedimentation tank at a certain water flow rate, and gravity separation is carried out through the sedimentation tank, and the impurity particles in the water are sedimented to the bottom of the sedimentation tank.
The above purification process can also be accomplished by a clarification tank which is a treatment structure that combines reaction and precipitation.
2 . 3 Filtration : After the raw water passes through the coagulation and sedimentation process, the turbidity of the water is greatly reduced, but the precipitated water flowing into the pool through the sump still retains some fine impurities, and passes through the granular filter material in the filter (such as quartz sand, Anthracite, etc.) intercepts fine impurities in the water, further reducing the turbidity of the water. When the raw water turbidity is low, the raw water after the input of the chemical agent can directly enter the filtration treatment without undergoing a treatment process such as coagulation or sedimentation. According to the introduction of swimming pool equipment , the above clarification process (coagulation, sedimentation and filtration) can reduce the turbidity of raw water, and is also effective for the removal of color, bacteria, and viruses. For high turbidity raw water, the grit chamber or pre-sinking tank is usually used to remove the coarse-grained sediment particles.
