  • What is a conventional flocculating agent?
  • The conventional flocculating agent can be classified into inorganic and organic additives. The inorganic mineral additives/metal salts are often used as coagulants, such as FeCl 3, AlCl 3 and polyaluminium chloride (PAC), whose performance is poor compared to organic flocculants [ 4, 5, 6 ].
  • What flocculants are used in soil conditioning?
  • Flocculants are agents that make fine and subfine solids or colloids suspended in the solution form large loose flocs through bridging (Fig. 9.4), thus achieving solid-liquid separation. The most commonly used flocculants for soil conditioning are polyacrylamide, carboxymethyl cellulose (CMC), and polyanionic cellulose (PAC).
  • What is a flocculant used for?
  • Normally, a flocculant is used in conjunction with mechanical treatment. For example, flocculants can be added at the flow line to increase the particle sizes so they can be removed with the shaker screen. Flocculants are also added to drilling fluid being processed by a centrifuge.
  • How much does a flocculant cost?
  • The cost of a flocculant depended on the dosage and varied between US $5.19 and $221.58 per metric ton of dry algal biomass (Table 3). Which flocculant was cheaper, depended on the alga. For most cases in Table 3, ferric chloride was cheaper, but for Neochloris sp. and Nannochloropsis salina, aluminum sulfate was cheaper.
