Particle Size and Density:
- Larger and denser particles settle faster than smaller or lighter particles.Biological Activity:
- Organisms such as algae and bacteria can affect sedimentation through processes like biofilm formation, which can enhance particle aggregation.Chemical Composition:
- The presence of certain chemicals or pollutants can alter the properties of sediment particles, affecting their behavior in suspension and settling.Concentration of Suspended Solids:
- Higher concentrations can lead to flocculation, where particles clump together, increasing their settling rate.Fluid Velocity:
- Higher flow velocities can keep particles in suspension, while slower velocities allow them to settle.Water Temperature:
- Temperature affects water density and viscosity, which can influence the settling rates of particles.
