  • How to use compound flocculant in oily wastewater treatment?
  • The compound flocculant in oily wastewater treatment can achieve best results at optimum conditions of temperature 45 °C, settling time 60 min, and two stirring stages, 250 r·min for 3 min followed by 100 r·min for 7 min.
  • Can oily wastewater be treated by coagulation/flocculation?
  • The mechanisms, challenges and research direction of oily wastewater treatment by coagulation/flocculation are discussed. Coagulation/flocculation presents an excellent removal efficiency on oily wastewater. Combined technologies for oil removal can meet strict effluent guidelines.
  • Is CS-G-PDBC a good flocculant for oily wastewater treatment?
  • A study reported a novel flocculant CS-g-PDBC with amphiphilic and cationic groups. In comparison to chitosan, CAPM and PAC, CS-g-PDBC with a significantly broadened flocculation window, thus can achieve enhanced efficiency in the oily wastewater treatment.
  • Can PAC/pmaptac composite flocculant be used in dyeing wastewater?
  • The above results will not only fill the gaps in the research of PAC/PMAPTAC composite flocculant during the treatment of dyeing wastewater, but also pro-vide an experimental basis for its application in dyeing wastewater and expand the application fields of PMAPTAC. 2.
