Ultrasound assisted wet media milling synthesis of ...
Wet media milling is a mechanochemical method to reduce the particle size to the nano-size, which is a necessary step for all the LFP synthesis processes. During milling, mechanical energy induces the collapse between the media (a hard material, such as yittria-stabilized-zirconia), and the particles in a liquid medium.

Stormwater wet pond fact sheet - Minnesota Stormwater Manual
Most wet ponds have a forebay, a small pool of water that absorbs the energy of the incoming water and allows sediment to settle. Water flows from the forebay to a second pool, where additional settling occurs. The water level in this second pool, called the primary pool, is controlled by an outlet structure.

For most products, the wet granulation process has three parts 1. Powder Wetting 2. Nucleation 3. Further nucleation or Agglomeration As the granulation cycle progresses: -the mean particle size increases -the particle size distribution narrows -the granules become more spherical -density increases -porosity decreases 1. Powder Wetting
Long-Acting Injectable Nanoparticle Technologies
Wet milling "The major manufacturing technique for commercially preparing nanosuspensions is wet milling, in which the active agent, in the presence of surface stabilizer(s), is broken down in size by milling media. Media milling can be considered a modernized version of the earlier ball mill, which used larger spheres in a dry state.
