The return of favourable conditions is stimuli for activating metabolic pathways accompanied with excystment (i.e., reversion into the trophozoite stage) leading to reproduction of their species.
In our experiments it was important to determine the elasticity of the 3A9 cells in the different conditions that were used for activating the cells.
These results suggest that high salinity stress, not the salinity condition itself, is important for activating lipid accumulation mechanisms in microalgae.
The optimum conditions for MP activated carbon preparation were obtained by using activation temperature of 828 °C, activation time of 1 h and IR of 3.0, which resulted in 80.35% of RBBR removal and 20.76% of activated carbon yield.
The optimum conditions for preparing activated carbon from OPF were found as follows: activation temperature of 850 °C, activation time of 1 h and KOH char ratio of 3.75:1.
The optimum conditions for preparing activated carbon from coconut husk were found as follows: activation temperature of 816 °C, activation time of 1 h and KOH char ratio of 3.9.
The most ideal conditions for preparing activated carbon from Prosopis africana seed hulls (PASH-AC) were investigated using sodium acetate (CH3COONa) as an activating agent.
A hybrid MBR operated in series provides certain operational flexibility, ensures more stable conditions for the activated sludge leading to a more stable MBR operation at energy and cost efficient conditions.
The optimum conditions for preparing activated carbon from EFB for adsorption of 2,4,6-TCP were found as follows: CO2 activation temperature of 814 °C, CO2 activation time of 1.9 h and IR of 2.8, which resulted in 168.89 mg/g of 2,4,6-TCP uptake and 17.96% of activated carbon yield.
The optimum conditions for preparing activated carbon from coconut husk for adsorption of 2,4,6-TCP were found as follow: CO2 activation temperature of 750 °C, CO2 activation time of 2.29 h and KOH char impregnation ratio of 2.91, which resulted in 191.73 mg/g of 2,4,6-TCP uptake and 20.16 % of activated carbon yield.
