“…Livestock compost wastewater is also one of the effluents most produced in the livestock industry. Livestock compost is described as an important source of some organic and inorganic components [105]. Some of these components can be easily broken down into simpler molecules, which in turn can provide a source of easily fermentable constituents for consortium support in MFCs [106].…”

In recent years, there has been a significant accumulation of waste in the environment, and it is expected that this accumulation may increase in the years to come. Waste disposal has massive effects on the environment and can cause serious environmental problems. Thus, the development of a waste treatment system is of major importance. Agro-industrial wastewater and waste residues are mainly rich in organic substances, lignocellulose, hemicellulose, lignin, and they have a relatively high amount of energy. As a result, an effective agro-waste treatment system has several benefits, including energy recovery and waste stabilization. To reduce the impact of the consumption of fossil energy sources on our planet, the exploitation of renewable sources has been relaunched. All over the world, efforts have been made to recover energy from agricultural waste, considering global energy security as the final goal. To attain this objective, several technologies and recovery methods have been developed in recent years. The microbial fuel cell (MFC) is one of them. This review describes the power generation using various types of agro-industrial wastewaters and agricultural residues utilizing MFC. It also highlights the techno-economics and lifecycle assessment of MFC, its commercialization, along with challenges.

“…On the offset, diatoms flourish well in wastewaters by utilizing several macronutrients such as carbon, nitrogen, phosphorus, silica, and micronutrients such as iron, magnesium, calcium, potassium, manganese, copper, and cobalt required for their growth and photosynthesis to form biomass [ 78 , 79 ]. They not only utilize metals as nutrients but also remediate dyes, drugs, etc .…”

Microalgae have been recognized as one of the most efficient microorganisms to remediate industrial effluents. Among microalgae diatoms are silica shelled unicellular eukaryotes, found in all types of water bodies and flourish very well even in wastewater. They have their silica cell wall made up of nano arrayed pores arranged in a uniform fashion. Therefore, they act as smart nanocontainers to adsorb various trace metals, dyes, polymers, and drugs which are hazardous to human as well to aquatic life. The beautiful nanoarchitecture in diatoms allows them to easily bind to ligands of choice to form a nanocomposite structure with the pollutants which can be a chemical or biological component. Such naturally available diatom nanomaterials are economical and highly sensitive compared to manmade artificial silica nanomaterials to help in facile removal of the toxic pollutants from wastewater. This review is thus focused on employing diatoms to remediate various pollutants such as heavy metals, dyes, hydrocarbons detected in the wastewater. It also includes different microalgae as biosensors for determination of pollutants in effluents and the perspectives for nanotechnological applications in the field of remediating pollutants through microalgae. The review also discusses in length the hurdles and perspectives of employing microalgae in wastewater remediation.

One of the most widespread problems afflicting people throughout the world is adequate access to clean water. Problems with water are expected to grow worse in the coming decades, with water scarcity occurring globally, even in regions currently considered water-rich. Research on the effects of temperature, transmembrane pressure (TMP), and aeration rate on the quality of effluent is of great significance in the case of membrane bioreactor. By means of the box-Behnken design (BBD) response surface methodology experiments; for the experimental investigation, the three factors are selected for optimization like the temperature is optimized in the range of 27.6-37.4 °C, transmembrane pressure is 35-63 mm Hg, and aeration rate is optimized in the range of 75-90 L/min and regression models are established. The optimal control parameters of temperature, TMP, and aeration rate are found utilizing the BBD optimizer. The removal mechanism of pollutants is discussed, and GC-MS analysis of effluent of the MBR system is also reported. The results show that the aeration flow rate affected effluent quality more significantly compared to temperature and TMP. When the aeration flow rate is 90 L/min, the temperature is 37.4 °C, and TMP is 35 mm Hg, the obtained COD, BOD, TKN, and TP values achieve the standard quality governed by the Central Pollution Control Board (CPCB) of India.
