  • Can polymer flocculants be used in oily wastewater treatment?
  • A summary of diverse coagulants/flocculants in oily wastewater treatment. To improve their application potential, polymer flocculants can be modified by chemical or physical approaches (Das et al., 2012).
  • What is the application of flocculation and coagulation in oily wastewater?
  • This paper mainly summarizes the application of flocculation and coagulation in oily wastewater and oily sludge in recent years. Flocculation and coagulation are important means to treat oily pollutants. In recent years, great progress has been made in the research of flocculants and coagulants.
  • How does flocculation remove oil from wastewater?
  • The removal of oil from wastewater through flocculation is both a chemical and physical process . Coagulation occurs when the repulsive interaction between the electrical double layers is sufficiently reduced through the addition of appropriate chemicals, enabling the particles to approach each other.
  • Do coagulants/flocculants affect the treatment performance of oily wastewater?
  • For the treatment performance of oily wastewater, different coagulants/flocculants usually present different pH dependency. Compared to nonionic flocculants, the charges on the surface of the colloids in oily wastewater and ionic coagulants/flocculants are significantly affected by the pH (Yang et al., 2016).
