Preparation and Coagulation Performance of Poly Silicate Aluminium Ferric Boron (PSAFB)

Some conditional experiments for the preparation of Poly Silicate Aluminium Ferric Boron (PSAFB) composite flocculant and its coagulation and flocculation for the removal of CODCr were conducted and discussed. Preliminary results show the optimum synthesis condition as follows: Si/Al( mole ratio) =2/1, Si/Fe( mole ratio)=1/1,Si/B( mole ratio)=10/1. Under optimal operating conditions, PSAFB can remove 69.3% of CODCr from the printing and dyeing wastewater.
