The quantity of chlorine remaining following this is named residual chlorine. This stays inside the water from the distribution system, preserving it from any micro-organisms Which may enter it right up until the water reaches the consumers.
Physical processes for mechanical preparing for example aeration, sedimentation or thermal affect. This also features using screens, filters and sieves.
