How do clarifiers work?
The large flocs will settle out of suspension via gravity. Clarifiers can remove a very large percentage of the suspended materials in water. In some plants, clarifiers remove as much as 90% of the suspended solids load. Particles that do not settle will be removed by filtration in the next treatment step.
What is coagulation in water treatment?
History of Coagulation in Drinking Water Treatment. Coagulation has been an important process in high-rate filtration plants in the United States since the 1880s. Aluminum and iron salts have been used in the coagulation process since the beginning. These salts are still the most commonly used coagulants today.
What is turbidity in water?
This cloudiness is known as turbidity . Visual turbidity is unpleasant to consumers. Visual turbidity is also an indicator to operators and regulators that the water may still contain pathogens. The Surface Water Treatment Rule therefore requires that turbidity be removed to very low levels.
What is the process of increasing the tendency of small particles to attach to one another and to attach to surfaces such as the
Coagulation . Coagulation is defined as the water treatment process of increasing the tendency of small particles to attach to one another and to attach to surfaces such as the grains of a filter bed. Many surface water supplies contain particles that are too small to settle out of solution on their own.
Why is filter loading rate important?
The filter loading rate is a critical parameter in the operation of the treatment plant because it determines the water velocity through the filter and the filter run times. Filter run time is the length of time that a filter can be in production before it has to be backwashed.
What are the common coagulants used today?

How does contact time work in water treatment?
In order for systems to be sure that they are properly disinfecting the filtered water, the Surface Water Treatment Rule requires systems to provide enough contact time. Contact time (CT) is a function of the known disinfection concentration and the amount of time that the disinfectant is in contact with the water. Contact time is expressed in terms of mg/L-min. The EPA has published tables that show how much CT credit water systems will receive. In order to use these tables you use the concentration of chlorine, time, water temperature and pH.
