This video shows liquid-solid separation reactions in various wastewater streams due to polymer flocculants.
You can see how solids fall out of liquid suspension in the treated wastewater vs. the control tubes.
Polymer flocculants are added to the wastewater to create flocculation and increase the rate that solids settle out of liquid suspension. Flocculation occurs when flocculants pull small particles together to form larger particles or macro-flocs. Because they're larger, they're heavier and fall out of liquid suspension quicker.
The process of falling and stacking particles is called sedimentation.
So flocculation leads to increased sedimentation. In return, you're able to separate solids from liquid quicker.
Polymer flocculants are used regularly in water treatment. They're used by themselves in settling ponds and other applications or to aid mechanical dewatering.
Jar tests are a great first step to dealing with solids and colloids in your wastewater. They'll determine the best polymer and chemistry to settle the solids and determine how you can remove them from your wastewater.
