Abstract:

Harmful cyanobacteria blooms are a major concern for water managers worldwide because they have negative environmental social and economic impacts This study aimed to evaluate cyano bacteria removal performance and water quality by electroflotation using titanium electrodes as a pre treatment in water treatment plants WTPs Water quality toxicity cyanobacterial cell integrity and cyanotoxin analysis were performed An experimental design was carried out to determine the optimum operational parameters OOP for cyanobacteria removal The identified OOP were flow rate of 100 06 m3 m 2 d 1 and current density of 72 10 A m 2 resulting in an energy consump tion of 1 97 kWh m 3 The reactor at OOP operating for 6h was able to remove 97 of cyanobac teria in a continuous flow reactor Furthermore dissolved organic carbon turbidity and apparent color decreased 41 55 and 52 respectively Phytotoxicity analyses showed seed germina tion and radicle growth rates greater than 75 and hypocotyl growth inhibition rates from 3 to 22 Roots showed no growth inhibition compared with the positive control Cell permeability analysis revealed cell wall alterations in cyanobacteria after electroflotation however cyanotox ins were not detected in treated water These findings indicate that electroflotation using titanium electrodes is a viable alternative as a pretreatment in WTPs 2023 Desalination Publications All rights reserved
