Answer: hi friend hope it helps
Explanation:
Sedimentation is a physical water treatment process using gravity to remove suspended solids from water. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. Settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation.
Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains Ozonation - Dissolving a low concentration of ozone into the water, providing rapid and efficient water disinfection.
disinfection by ozone
Ultraviolet (UV) - Irradiating the water with UV-beams.
Chlorination - Dosing chlorine compounds to the water resulting in a residual disinfecting chemical concentration.
Other technologies include e.g. bromine, peracetic acid, iodine, copper and silver ions, potassium permanganate, fenols,...the solid particles. Either the clarified fluid or the solid particles …
