“…As specified by ISO 13408-1, sterility assurance level (SAL) is used to characterise the killing efficiency of a treatment process, with the treatment process being very efficient if the SAL is very poor. Log reduction accepted by the United States Environmental Protection Agency (USEPA) is a term widely used to measure the efficiency of disinfection processes [ 37 ]. SAL is generally written as 10 n .…”

“…First (1 GBs) and second-generation biofuels (2 GBs) do not represent viable options, as 1 GBs are primarily obtained from the use of crops exclusively grown for fuel production that compete with food production in terms of arable land and freshwater needs, and 2 GBs from plant scraps that use unsustainable production methods [94]. Instead, several studies have shown that third-generation biofuels (3 GBs) seem to overcome the main challenges faced by 1 GBs and 2 GBs [95]. 3 GBs are mainly produced from microalgae [10], which can be grown on non-arable land using non-potable water, avoiding competition with the agriculture industry [96].…”

Microalgal Systems for Wastewater Treatment: Technological Trends and Challenges towards Waste Recovery

et al. 2021

Wastewater (WW) treatment using microalgae has become a growing trend due the economic and environmental benefits of the process. As microalgae need CO2, nitrogen, and phosphorus to grow, they remove these potential pollutants from wastewaters, making them able to replace energetically expensive treatment steps in conventional WW treatment. Unlike traditional sludge, biomass can be used to produce biofuels, biofertilizers, high value chemicals, and even next-generation growth media for “organically” grown microalgal biomass targeting zero-waste policies and contributing to a more sustainable circular bioeconomy. The main challenge in this technology is the techno-economic feasibility of the system. Alternatives such as the isolation of novel strains, the use of native consortia, and the design of new bioreactors have been studied to overcome this and aid the scale-up of microalgal systems. This review focuses on the treatment of urban, industrial, and agricultural wastewaters by microalgae and their ability to not only remove, but also promote the reuse, of those pollutants. Opportunities and future prospects are discussed, including the upgrading of the produced biomass into valuable compounds, mainly biofuels.

Microalgae have been found to have high prospects in wastewater treatment, particularly from agriculture. However, the uneconomical algal medium growth has become the major disadvantaged in algal industry. Multiple attempts includes the development of microalgae phycoremediation technology has been integrated into wastewater treatment to reduce the cost of expensive wastewater remediation. Utilising wastewater as a low-cost nutrient medium offers a synergistic effect of wastewater nutrient removal and co-production of valuable biomass simultaneously. This paper is mainly focused on potential, ability, strategy, application (i.e., palm oil wastewater), limitation and challenges of microalgae in agricultural wastewater treatment using phycoremediation. The understanding of cultivating microalgae using agriculture wastewater shall promote the utilisation of wastewater more sustainably in the future. The possible solutions in the application of microalgae for aquaculture and agriculture sector is also discussed in this review. Overall, the utilisation of wastewater in media cultivation for microalgae is restricted due to the expensive treatment and safety concern. However, this pitfall can be reduced in the future together with a further intensive scientific study, advanced technology, better management system and applying better standard protocol.
