Abstract:
Industrial sectors which huge amount of clean water is used in the world and a large part of the process water is discharged in the form of waste water. The purpose of this study is to investigate the usability of the mixed wastewater including dairy, textile and domestic sources in microalgae biomass. For this reason, the mixed wastewater used in this study was taken from two different points of the treatment plant (activated sludge effluent, discharge effluent) of the plant. The experiments were carried out in a batch culture system, in 5 L bottles triplicates. Diatom Nitzschia umbonata (Ehrenberg Lange-Bertalot, 1978) were used. Chlorophyll-a and b-based microalgae growth and changes in specific growth rates were investigated. According to the results obtained, the microalgae species were adapted well to the mixed wastewater and reached the highest growth rate at the trial of effluent water. Chl-a based growth rates of N. umbonata species (1, 66 ± 1, 09 days-1) were significantly higher than the control group (p
