Study of Adsorbability of the Colloidal Particles from Different Stages of a Conventional Water Treatment Plant
The adsorbability of colloidal particles from different stages of a conventional water treatment plant was studied with the assistance of micro-membrane filtration experiment. The microfiltration (MF) performance and the scanning electron microscope (SEM) images of the foulants on membrane surface were investigated. The results showed that the particles in the ozonated water (OW) had the strongest adsorbability, and stronger than that in the clarified water (CW); and the particles in the sand filtrated water (SFW) had relatively weaker adsorbability than that in the raw water (RW). The particles in the sand filter backwash water (SFBW) were mainly consisted of detached aggregates and had weak attachment with the membrane surface.
