“…PAOs are the main microorganisms responsible for phosphorus (P) removal in AGS by means of an enhanced biological phosphorus removal (EBPR) process [ 17 , 63 ]. The EBPR process is the biological mode of P removal; thus, it is a better alternative than chemical P removal [ 64 ]. The EBPR process consists of alternating anaerobic and aerobic phases.…”

Nowadays, the discharge of wastewater is a global concern due to the damage caused to human and environmental health. Wastewater treatment has progressed to provide environmentally and economically sustainable technologies. The biological treatment of wastewater is one of the fundamental bases of this field, and the employment of new technologies based on granular biofilm systems is demonstrating success in tackling the environmental issues derived from the discharge of wastewater. The granular-conforming microorganisms must be evaluated as functional entities because their activities and functions for removing pollutants are interconnected with the surrounding microbiota. The deep knowledge of microbial communities allows for the improvement in system operation, as the proliferation of microorganisms in charge of metabolic roles could be modified by adjustments to operational conditions. This is why engineering must consider the intrinsic microbiological aspects of biological wastewater treatment systems to obtain the most effective performance. This review provides an extensive view of the microbial ecology of biological wastewater treatment technologies based on granular biofilms for mitigating water pollution.

“…Physico-chemical technologies for phosphorus removal include processes such as precipitation, sorption and ion exchange mechanisms [99]. Well-enhanced biological nutrient removal processes also exist [100,101]. Debowski et al [102] recently reported on the anaerobic reactor filling as a modern economically feasible and effective phosphorus removal method by metal dissolution.…”

“…The known of phosphate species is important for the determination of the removal mechanism [6]. Phosphorus removal techniques include adsorption [7], chemical precipitation [8], ion exchange [9], electrodialysis [10], membrane filtration [11], electrocoagulation [12] and biological phosphate removal [13,14]. Among these methods, adsorption and chemical precipitation are widely used for phosphate removal [15].…”

In this study, the effect of wastewater pH on phosphate removal by electrocoagulation method using aluminum plate electrodes was investigated. For this purpose, experiments were carried out at initial pH values ranging from 3-10, and the effect of the initial pH of the wastewater on phosphate removal efficiency, energy consumption and reaction rate was analyzed. From the results obtained, it was determined that the initial pHs of the optimum wastewater was 3 and 4. Because at low pH, both phosphate removal efficiency is high and the energy consumption of the system is low. While 97% removal efficiency is reached in 20 minutes at pH i =3, it increases in this period with the increase of the wastewater initial pH. These data show that the removal rate is higher at lower initial pHs. While the 1st degree reaction rate constant at pH i =3 is k 1 =0.2154 min -1 , this value decreases to k 1 =0.071 min -1 at pH i =10. At pH i =3, the energy consumption of the system has been determined as 0.553 kWh m -3 in 12 minutes of contact time. In addition, in the measurements made during the trials, it was observed that the highest PO 4 -P removal occurred during the period when the pH of the system was between 5-7.
