What is the purpose of a Clearwell?
A clear well is an enclosed tank that is associated with a treatment plant. Clear wells are used to store filtered water of sufficient capacity to prevent the need to vary the filtration rate with variations in demand. Clear wells are also used to provide chlorine contact time for disinfection.
What is post chlorination in water treatment?
Postchlorination is a treatment process that occurs before water leaves the treatment plant. It is the addition of chlorine to the water in order to prevent microbial growth. Ideally, there should be 0.2 to 0.1 parts of chlorine per million parts of water.
What is pumping system of water distribution?
Pumping stations in a water distribution system are necessary where water is pumped directly into the system (e.g. from a lake) or where pressure has to be increased because there is an insufficient difference in water levels in gravity flow distribution systems.
What is the difference between pre chlorination and post chlorination?
During pre-chlorination, chlorine is usually added to raw water after screening and before flash mixing. Post-chlorination, in contrast, is often the last stage in the treatment process.
How do you disinfect drinking water?

How do pumping stations work?
How does a pumping station work? Essentially, the components of a sewage pumping station work together to move sewage from one location to another. Sewage gradually collects inside the chamber and, once it reaches a predetermined level, the float switch is tripped and the pump automatically kicks into action.
What is the purpose of aeration in water treatment?
In industrial water conditioning, one of the major objectives of aeration is to remove carbon dioxide. Aeration is also used to oxidize soluble iron and manganese (found in many well waters) to insoluble precipitates. Aeration is often used to reduce the carbon dioxide liberated by a treatment process.
What do you mean by pre and post chlorination?
Chlorination is the application of chlorine to the water for the purpose of disinfection. During pre-chlorination, chlorine is usually added to raw water after screening and before flash mixing. Post-chlorination, in contrast, is often the last stage in the treatment process.
Does vinegar purify water?
Vinegar cannot sterilize, disinfect or purify water. Vinegar is not registered as a disinfectant by the EPA and should only be used to help reduce the number and spread of some germs on surfaces or objects.
What does Clearwell processing and Analysis module do?
