AB  - Cyanobacterial bloom causes the release of algal organic matter (AOM), which 
      inevitably affects the treatment processes of natural organic matter (NOM). This 
      study works on treating micro-polluted surface water (SW) by emerging coagulant, 
      namely titanium sulfate (Ti(SO(4))(2)), followed by Low Pressure Ultrafiltration 
      (LPUF) technology. In particular, we explored the respective influence of 
      extracellular organic matter (EOM) and intracellular organic matter (IOM) on 
      synergetic EOM-NOM/IOM-NOM removal, functional mechanisms and subsequent 
      filtration performance. Results show that the IOM inclusion in surface water body 
      facilitated synergic IOM-NOM composite pollutants removal by Ti(SO(4))(2), 
      wherein loosely-aggregated flocs were produced, resulting in floc cake layer with 
      rich porosity and permeability during LPUF. On the contrary, the surface water 
      invaded by EOM pollutants increased Ti(SO(4))(2) coagulation burden, with 
      substantially deteriorated both UV(254)-represented and dissolved organic matter 
      (DOC) removal. Corresponded with the weak Ti(SO(4))(2) coagulation for EOM-NOM 
      removal was the resultant serious membrane fouling during LPUF procedure, wherein 
      dense cake layer was formed due to the compact structure of flocs. Although the 
      IOM enhanced NOM removal with reduced Ti(SO(4))(2) dose and yielded mitigated 
      membrane fouling, larger percentage of irreversible fouling was seen than NOM and 
      EOM-NOM cases, which was most likely due to the substances with small molecular 
      weight, such as microcystin, adhering in membrane pores. This research would 
      provide theoretical basis for dose selection and process design during AOM-NOM 
      water treatment.
