Background

Coarse graining (agglomeration) refers to the use of the property of oil and water phase having very different affinity for the agglomerate material, wherein when the oily waste water passes through the bed filled with the agglomerate material, the oil particles are captured by the material and retained on the surface and in the pores of the material. As the trapped oil particles increase, deformation occurs between the oil particles, which coalesce into larger oil particles. From stokes' formula, the oil particle buoyancy rate in water is proportional to the square of the oil particle diameter, and larger oil particles are easily separated from water after coalescence.
