“…At the Warsaw University of Life Sciences, for the first time MFC technology has been applied in the management of wood industry wastewater. All the investigations were conducted with single-chamber reactors with an air cathode ( Figure 1) [5]. In a single-chamber reactor a graphite anode was placed in an anaerobic chamber filled with hydrothermal treatment wastewater (WHTW).…”

“…Table 1 shows the chemical composition of wastewater from basins in different plants where hardwood was treated hydrothermally. When the water in the basin was changed once a year [4] or less frequently [5], the total amount of solids in the wastewater was much higher (>2000 mg/L) than in the case of water changed every few weeks, where total solids were below 500 mg/L [2,10]. The amount of lignin and tannins was also higher (560-870 mg/L) when the water was changed less frequently versus 250 mg/L in water changed every few weeks [2,10].…”

“…As a result, the microbial consortium was dominated by Thermoanaerobacterium species, which produced a power density of 71 mW/m 2 in the MFC from raw WHTW without any supplementation. Thermoanaerobacterium are thermophilic bacteria known for their ability to ferment cellulose and hemicellulose with end products such as acetate or hydrogen that can be used by electrogenic bacteria for current production [5]. frequently versus 250 mg/L in water changed every few weeks [2,10].…”

“…Investigations into WHTW showed that power production in WHTW-fed MFCs can be enhanced by bioaugmentation of WHTW by the addition of municipal wastewater [5]. This approach allowed development of new consortia where the most abundant microorganisms were Anaerobaculum mobile and Hydrogenophilus halorhabdus, and the power produced was increased from 71 to 360 mW/m 2 (Figure 2, plant 2).…”

“…Wastewater from production of wood-based materials is usually highly polluted. Chemical oxygen demand (COD) values were measured in a wide range from 200 to 11,000 mg O 2 /L depending on the operation stage that generated the wastewater [3][4][5]. They contain a wide range of various substances among which wood degradation products, wood extractives, heavy metals or even surfactants introduced during cleaning processes can be found.…”

Although the wood-based panel industry is not considered to be a water-consuming sector, it generates ca. 600 M m3 of wastewater every year on a global scale. The wastewater is usually highly polluted and environmentally toxic even after dilution. Common wastewater treatment techniques require high-energy input or addition of various chemicals to the treated wastewater, which cause secondary pollution and production of toxic sludge. Microbial fuel cells (MFCs) have become an attractive technology, allowing for zero-energy treatment of various types of wastewater with simultaneous production of electric current. Recent investigations have shown that MFCs can also be utilized for sustainable treatment and energy production from the wastewater generated by the wood-based panel industry. This article contains a critical summary of the investigations in this field as well as a discussion of the research needed and perspectives for the future.

A comprehensive review on emerging trends in industrial wastewater research

et al. 2022

View full text Add to dashboard Cite

Rapid industrialization is one of the intricate factors that is linked to the depletion of water resources and increased generation of wastewater. Due to various obstructions and impediments, such as ineffective treatment solutions, exorbitant prices, lack of basic amenities, insufficient financial assistance, and technical expertise, sustainable treatment of industrial effluents has become an onerous process in most parts of the world. The majority of current treatment solutions are conventional and outdated, and thus fall short to remove all the contaminants efficiently from the industrial wastewater. Moreover, poorly treated or untreated industrial effluents are indiscriminately dumped into water bodies such as lakes, ponds, and rivers, causing substantial health hazards to humans and animals and serious threats to the aquatic ecosystem. Thus, there is a need for highly efficient, cost-effective, and sustainable technologies for the treatment of industrial wastewater. Employment of microbial technologies such as microbial fuel cells and microalgal technologies, treatment of wastewater can be coupled with the production of bioelectricity and valuable biomass, respectively. Moreover, with nanofiltration and biochar technologies, the efficiency of the overall treatment procedure can be increased to a greater extent. The present review aims to highlight opportunities and challenges associated with some of the emerging trends in industrial wastewater research.
