  • Can hypochlorite be used in wastewater and sludge treatment?
  • The hypochlorite feasibility and gaps in wastewater/sludge treatment are analyzed. As cost-effective and high-efficient oxidants, the hypochlorite chemicals have been widely utilized for bleaching and disinfection. However, its potential applications in wastewater treatment and sludge disposal were less concerned.
