“…On the other side, it is worth mentioning the eventual positive impact of the cake layer: A compact and more resistant cake layer acts as a secondary filtration layer, protecting the membrane surface from small organics molecules responsible for irreversible fouling (Low et al, 2016;Fortunato et al, 2020;Novoa et al, 2020). Javadi et al (2014) found out that an increase in the cake layer resistance, induced by a compact and nonporous structure, improved the permeate quality (Javadi et al, Fletcher et al, 2011a;Wang et al, 2014;Fortunato et al, 2017;Bagheri and Mirbagheri, 2018;Mat Nawi et al, 2020 Irreversible: removed by chemical cleaning…”

The use of algal biotechnologies in the production of biofuels, food, and valuable products has gained momentum in recent years, owing to its distinctive rapid growth and compatibility to be coupled to wastewater treatment in membrane photobioreactors. However, membrane fouling is considered a main drawback that offsets the benefits of algal applications by heavily impacting the operation cost. Several fouling control strategies have been proposed, addressing aspects related to characteristics in the feed water and membranes, operational conditions, and biomass properties. However, the lack of understanding of the mechanisms behind algal biofouling and control challenges the development of cost-effective strategies needed for the long-term operation of membrane photobioreactors. This paper reviews the progress on algal membrane fouling and control strategies. Herein, we summarize information in the composition and characteristics of algal foulants, namely algal organic matter, cells, and transparent exopolymer particles; and review their dynamic responses to modifications in the feedwater, membrane surface, hydrodynamics, and cleaning methods. This review comparatively analyzes (i) efficiency in fouling control or mitigation, (ii) advantages and drawbacks, (iii) technological performance, and (iv) challenges and knowledge gaps. Ultimately, the article provides a primary reference of algal biofouling in membrane-based applications.

The occurrence of fouling in Membrane Bioreactors (MBRs).reduces the performance of the system can be overcome by integrating electro-oxidation process in which different applied current density (CD) have been investigated. The optimal CD was 0.748 A/m2 which was suitable for the long-time operation of IMBR and observed that the removal percentile for total organic compounds (TOC), chemical oxygen demand (COD) was above 90% with total dissolved solids (TDS) of 60% at 400kPa constant pressure. Scanning electron micrographs (SEM) showed less void volume and pore constriction and the increase in permeate flux was 45% with extended backwashing time of 140 minutes. The fouling mechanism also verified by Hermia models, lumped parameter kinetic modelling and thermodynamic parameter with activation energy estimation exhibits lesser internal fouling of standard error 0.00459, 58.296 kJ/mol, − 0.1191 kJ/mol, 94.621 kJ/mol, 52.428 kJ/mol and the observed results and more reliable and feasible. The most striking observations in this study were that IMBR can be operated without the problem of filamentous bulking, and electro-oxidation significantly alternated the structural and morphological sludge flocs. The results implied that electro-oxidation might be the key factor for the success in fouling mitigation in IMBR.
