Every drop of water you drink has been on the Earth for billions of years.  You likely are drinking the same water that ancient creatures drank long ago.  Of course, water is gradually purified over time, so there’s nothing disgusting about that.  However, to speed up the process, we have ways of treating water so that clean water can be used again and again.  There are three stages to the recycling process: primary treatment, secondary treatment, and advanced treatment.

Primary Treatment

Large contaminants such as sticks, rags, and plastics are removed from the water using bar screens, which look like large rakes that capture these pieces.  Grit chambers and primary clarifiers continue to use basic screening and settling processes to get larger particles out of the water.

Secondary Treatment

Biological processes are used in the next stage.  Tiny microorganisms are used to consume organic material that can then be converted into material that will settle to the bottom.

Advanced Treatment

After passing through effluent sand filters, remaining particulates have been filtered out.  The water is then chlorinated to kill any remaining organisms, and then the excess chlorine is removed using sulfur dioxide.

What Role Do Static Mixers Play

Static mixers are used throughout the process.  They are especially useful in the advanced stage in order to ensure that chlorine and sulfur dioxide are adequately and efficiently mixed together so that they can properly treat the water.  PVC Static Mixers are common in this line of work, and their clear casing allows professionals to see the mixing process take place.  Furthermore, the particulates that are removed from the water must be managed as well, and static mixers are helpful in processing solid waste as well as other forms of waste materials.
