  • What flocculants are used in water treatment?
  • Aluminium-based Flocculants: Aluminium sulphate (alum) is the most common aluminium-based flocculant used in water treatment. Its effectiveness is attributed to its ability to neutralise the electrical charges on colloidal particles, promoting their aggregation and subsequent sedimentation.
  • Why is water treated with coagulation and flocculation?
  • Before we look in detail at the coagulation and flocculation process, you might be wondering – why is water treated with this method?
  • The main purpose of coagulation and flocculation is to treat turbid (hazy or cloudy) water, thus improving water quality.
  • What chemicals are used in water treatment?
  • These chemicals facilitate the removal of suspended particles and colloids through destabilisation and aggregation processes. Aluminium-based Flocculants: Aluminium sulphate (alum) is the most common aluminium-based flocculant used in water treatment.
  • Does flocculation strategy work in water treatment?
  • As the interest in application of flocculation strategy for water treatment has grown gradually, a number of review articles related to the flocculation process have been published in recent years. Table 2 lists selected review articles with their focus related to the flocculation process in water treatment.
