Why Should You Settle Water When Drinking It?

Do you know the importance of the settling agent for water treatment? When it comes to drinking water, you're usually looking to do one of two things: consume a good amount of water throughout your day or kill unwanted materials like bacteria, cysts and viruses. In either case, there are several ways to accomplish those goals. While letting natural sedimentation occur in your main source of drinking water may be an option, adding a settlement substance will help you speed up the process and remove substances more effectively than natural sedimentation would on its own.

Settling refers to allowing sediments or other unwanted materials settle out in a container by themselves. A settling agent speeds up that process by either causing particles to clump together and float faster (thereby making them easier to filter) or changing their surface charge, causing them to repel each other and separate faster.

A Few More Things About Settling Agent for Water Treatment

The best ways to settle out suspended solids from drinking or waste water are sedimentation and flocculation. Sedimentation is just what it sounds like-the idea that heavy particles will sink to the bottom of a container. This can be a useful method of dealing with waste-water, but not all solids are heavy enough to settle out by themselves. For example, when wastewater undergoes conventional wastewater treatment, chemical coagulants (typically alum) are used to cause suspended solids to clump together and sink.

However, there are several chemicals which do double duty as both coagulants and settling agents. These include iron salts such as ferric chloride, aluminum sulfate and aluminum chloride. Of these three options, aluminum sulfate is most commonly used in municipal wastewater treatment plants because it's relatively inexpensive compared to other options.

Final Thoughts

Suspended solids can be natural or anthropogenic (man-made). Solids that are naturally suspended in water bodies include silt, clay, and sand. Anthropogenic suspended solids are a result of human activities like dredging and mining and result in some of these particles being washed into rivers, lakes, and oceans. These settled particles affect public health by reducing oxygen levels in aquatic environments.
