As mentioned, the flocculant prepared in the flocculant system has a concentration of 0.5% w/w. Immediately downstream from the flocculant metering pumps, the flocculant must be diluted with fresh water to a final concentration of 0.05% w/w, i.e., for every litre of 0.5% flocculant solution, 10 litres of water are required to dilute it to a 0

Flocculant - an overview | ScienceDirect Topics

The optimal dose of a flocculant depends on many factors including the alga, its concentration, the nature of the culture medium (ionic strength, pH, concentrations of specific dissolved ions, concentration and nature of any dissolved organics), and temperature. Data on optimal dosages of some flocculants have been published.
