“…The latter was to improve the illuminated space in the tank. Other studies used a ratio of H/D = 16.7 and S/V = 0.7, where the reactor height was up to 16.7 times larger than the internal diameter (Zhang et al, 2018; Zhang, Huo, & Meng, 2020). These high ratios in the reactor design parameters considerably improved contact between bacteria and microalgae, achieving granules with larger size and higher algae concentration.…”

“…On the other hand, C, N and P sources commonly used as synthetic effluents to simulate domestic wastewater were glucose and/or sodium acetate, NH 4 Cl and KH 2 PO 4 . The mineral medium included CaCl 2 , MgSO 4 ·7H 2 O, H 3 BO 3 , CuCl 2 , AlCl 3 , MnSO 4 , among others (de Sousa Rollemberg et al, 2020; Zhang, Huo, & Meng, 2020; Zhao et al, 2018). In ABGS systems, C, N and P loads must be balanced with a light supply to maintain adequate microalgae growth and thus to obtain a system in which aeration is not required, and high nutrient removal efficiency is achieved (Boelee et al, 2014).…”

“…Several studies have demonstrated that algal-bacterial granular sludge (ABGS) processes are able to improve pollutant removal and microalgae sedimentation in comparison with traditional treatments. This is mainly due to the fact that ABGS processes are strongly influenced by the applied operating mechanisms, which promote symbiotic microbial interactions responsible for granule characteristics, process performance and the microbial biodiversity of the symbiosis (Nuramkhaan et al, 2019;Zhang, Huo, & Meng, 2020).…”

This article discussed the effect of the main operating parameter involved in the operation of algal–bacterial granular sludge (ABGS) systems as promising biological processes for wastewater treatment. The focus was on the operational ranges reported in the literature capable of achieving better granule properties, good stability and high removal capacities. This review identified that hydraulic retention time (HRT), light intensity (LI) and light/dark periods were the most influential operating factors on the formation, stability, settleability and organic pollutant removal efficiency of ABGS. The discussion argued that ABGS systems enhance industrial and domestic wastewater treatment due to additional advantages that provide the symbiotic interactions to process performance, maintaining lesser operating costs concerning aerobic granular sludges (AGS) and microalgae consortia. This review will improve the understanding of the operation of ABGS systems and thus further expand possible operating combinations that help to enhance microbial interactions, microalgae growth and external aeration self‐sufficiency in further research with a focus on its scaling up.

“…Studies have found that appropriate changes in environmental conditions can promote the lipid production, such as light, light intensity, and influent salinity. Under light conditions, the lipid production was 22.8 mg/g more than under dark conditions [ 73 ]. Meng [ 71 ] found that the light intensity in the range of 45, 90, 135, 180, and 225 μmol m −2 s −1 was positively correlated with the lipid production.…”

Traditional wastewater treatment technologies have become increasingly inefficient to meet the needs of low-consumption and sustainable wastewater treatment. Researchers are committed to seeking new wastewater treatment technologies, to reduce the pressure on the environment caused by resource shortages. Recently, a microalgal-bacterial granular sludge (MBGS) technology has attracted widespread attention due to its high efficiency wastewater treatment capacity, low energy consumption, low CO2 emissions, potentially high added values, and resource recovery capabilities. This review focused primarily on the following aspects of microalgal-bacterial granular sludge technology: (1) MBGS culture and maintenance operating parameters, (2) MBGS application in different wastewaters, (3) MBGS additional products: biofuels and bioproducts, (4) MBGS energy saving and consumption reduction: greenhouse gas emission reduction, and (5) challenges and prospects. The information in this review will help us better understand the current progress and future direction of the MBGS technology development. It is expected that this review will provide a sound theoretical basis for the practical applications of a MBGS technology in environmentally sustainable wastewater treatment, resource recovery, and system optimization.

Though the biological treatment employing bacterial strains has wide application in e uent treatment plant, it has got several limitations. Researches hence while looking for alternative biological organisms that can be used for secondary treatment came up with the idea of using microalgae. Since then, a large number of microalgal/cyanobacterial strains have been identi ed that can e ciently remove pollutants from wastewater. Some researchers also found out that the algal biomass not only acts as a carbon sink by taking up carbon dioxide from the atmosphere and giving oxygen but also is a renewable source of several valueadded products that can be extracted from it for the commercial use. In this work, the cleaning effect of different species of microalgae/cyanobacteria on wastewater from varied sources along with the value-added products obtained from the algal biomass as observed by researchers during the past few years are reviewed. While a number of review works in the eld of phycoremediation technology was reported in literature, a comprehensive study on phycoremediation of wastewater from different industries and household individually is limited. In the present review work, the e ciency of diverse microalgal/cyanobacterial strains in treatment of wide range of industrial e uents along with municipal wastewater having multi-pollutants has been critically reviewed.
