Experimental Analysis of Physical Parameters in Treated Water
Abstract: During the first phase, the surface water treatment plant at Saidabad treats 225 million liters of water per day. In the treated water, turbidity, color, total coliform, fecal coliform, and hardness are reduced; on the other hand, conductivity and total dissolved solids increase. In the wet season, turbidity is high due to relatively coarse particle dispersions in river water. All other parameters, such as color, total and fecal coliform, hardness, …
