A lab-scale advance wastewater treatment system that consists
of sequencing batch reactor (SBR), chemical-dissolved-air flotation
(DAF) and ultraviolet (UV) disinfection hybrid system was developed
for poultry slaughterhouse reclamation [55]. The SBR was
operated to remove nitrogen and the chemical–DAF system was
operated to remove phosphorus and remaining suspended solids.
The floated effluent was submitted to UV disinfection. The pollutants
and removal percentage for SBR, chemical-DAF and UV hybrid
in poultry slaughterhouse wastewater is reported in Table 5.
