Best Coagulant-flocculation polymer| polyaluminium chloride, โพลีอะลูมิเนียม ครอไลด์
The water treatment making process from surface water that is high turbidity is a problem that must be removed from clear water before service to people. Turbidity is caused by particles called colloids, such as clay, very small is call Suspended solid in water. The suspensions are unable to settle on their own with the charged of colloidal substances it is no sediment capture to large tablet, so it must be a way to make the suspended solids in the water with these small gatherings to large, The big particle became heavy enough to settle by its floc weight. The treatment process uses chemicals such as alum, Coagulant-flocculation polymer, polyaluminium chloride, โพลีอะลูมิเนียม ครอไลด์ etc., to make the tiny particles can clump together floc and bordered at large that can be easily precipitate For the process of building a large sediment by PAC น้ำ , Coagulant-flocculation, polyaluminium chloride, โพลีอะลูมิเนียม ครอไลด์ addition is a second step.
The process of sedimentation make the Floc ,Coagulation is a process that destroys ....
The charge of colloids using chemicals such as alum, PAC น้ำ , Coagulant-flocculation, polyaluminium chloride, โพลีอะลูมิเนียม ครอไลด์ to precipitate the suspension floc which is used to fast stir, after putting inorganic coagulants agent to cause the destruction of charged colloids at colliod surface.2. The process of Flocculation with anionic polymer or cationic polymer was increase the colloid attrative force to bacame big agrrometed particle hold up well. The new particle are big size and heavy weight enough to settle by gravity of the natural world which is used to slow stirring as slowly. The slow stire to small collide collaped and small floc clumping up big floc precautions when sediment or flocculation on process is be careful not to water velocity is too high the flocc might be broke.
The Rapid Mixing: Generally, it takes time about 1 to 3 seconds with stirring force as high as possible the generated the turbular. The hydraulic jump that relies on the turbulent flow of water, such as changing the speed of water flowing down the slope when the speed changes from high to low to turbulence occurs. To fill Coagulant-flocculation chemicals into mixing zone design for small water plants such as rural water supply.
