The application of microorganism for the removal of pollutants from environment provide cheaper substitutes to the traditional treatment methods. The selection of easily culturable and effective microorganism that could do the treatment is a major challenge. Microalgae present a viable, eco-friendly and economical agent of wastewater treatment and production of value-added substances such as biofuel, carotenoids and polyunsaturated fatty acids, pharmaceuticals and dyeing agents. In this article, we reviewed and presented the use of microalgae for the removal of several kinds of pollutants, the mechanisms employed for the degradation and their diversity in wastewater. The removal of pollutants such as nitrogen, phosphate, heavy metal, chemical oxygen demand, biological oxygen demand and dye by different strains as well as the mechanism involved were identified and discussed. Cultivation of microalgae in the large-scale void of bloom, mechanism of stress tolerance and the potential value-added substances to be produced while decontaminating the environment concomitantly were also highlighted. The article also highlighted the fate of organic pollutants in the application of microalgae biomass. This review demonstrated the use of microalgae for wastewater treatment to be a win-win strategy that has dual role of pollutants removal and multiple product formations. Such benefits can be enhancing via integrating multiple methods of treatments and microalgae engineering.

The recovery and effective treatment of ammonia nitrogen and phenols were issues that cannot be ignored for realizing the harmless treatment of CCW and the sustainable development of the coal chemical industry. This review summarized the current research status of phenols and ammonia nitrogen removal at home and abroad from three aspects: the recovery technology of phenols and ammonia nitrogen, the biochemical treatment technology of phenols and ammonia nitrogen, and the advanced treatment technology of phenols and ammonia nitrogen; Furthermore, the various technologies in terms of their advantages, disadvantages and practical application were analysed. Finally, in view of the concepts of energy saving, high efficiency, and sustainable health, the prospects of phenols and ammonia nitrogen recovery and treatment in future were discussed. The purpose of this review was to allow researchers in this field to use a more scientific approach to understand the research status and development trend of phenols and ammonia nitrogen in CCW and provide a reliable theoretical basis for the new exploration of phenol-ammonia recovery and treatment. It would be of great significance to promote the sustainable development of the coal chemical industry.

Mature landfill leachates are rich in nitrogen and a potential source of water and soil contamination, potentially causing eutrophication of surface water bodies. In developing countries, leachates have been treated together with municipal effluents in WWTP. However, there are few reports on nitrogen removal in these systems. This review evaluated studies using anammox-based processes, including partial nitrification and anammox (PN/A), focusing on mature leachates and their co-treatment with municipal wastewater. We aimed to identify anammox-based treatment strategies leading to high N and COD removal efficiencies. For PN/A, sequential batch reactors have been successfully used to treat different effluents such as leachates. Recirculation and leachate dilution in anammox-based processes were strategies successfully adopted to achieve high nitrogen removal. Temperatures above 30°C and pH values from 7.8–8.5 had positive effects on the performance of co-treatment processes. The best performances in the co-treatment processes using PN/A were achieved for dilution rates between 2 and 11.5 parts of municipal wastewater to 1 part of mature leachate, reaching N and COD removal efficiencies above 90% and 86%, respectively. Inhibition of nitrite-oxidizing bacteria, acclimatization of anammox bacteria for long periods, as well as extracellular polymeric substances production by anammox bacteria are important factors in the performance of PN/A systems for the co-treatment of mature leachate and domestic wastewater.

However, the pressmud being rich in nutrients and organic matter can be used for several purposes. The current review’s objectives are to explore the agricultural and industrial uses of pressmud, the role of microorganisms to improve its properties, and technological challenges & barriers in pressmud value addition. Two online databases, PubMed and Scopus, were used to search the relevant information using keywords ‘Pressmud’ and/or ‘Press mud’ and 457 results were obtained. After following exclusion criteria and removal of duplicate entries, out of the remaining 169 records, only 36 records were selected for final analysis based on title, abstract, and other relevant parameters. Furthermore, 62 records were included based on cross-referencing from selected literature. The evidence from different studies showed that pressmud is a rich source of nutrients, for example, calcium (Ca), silicon (Si), zinc (Zn), iron (Fe), copper (Cu), and manganese (Mn). The efficacy of pressmud compost could be improved using microorganisms, for example, Pseudomonas, Bacillus, Aspergillus, Trichoderma and Streptomyces. The pressmud has the potential to be used as a biofuel, microbial carrier, soil conditioner, bioremediation of heavy metals, animal feed, wax production, and concrete formation. However, the pressmud composition is affected by sugarcane varieties, soil type, and other environmental factors. Technological barriers are also a big challenge for researchers to exploit the potential use of pressmud in different industries. Therefore, extensive research on pressmud use in the agriculture sector is warranted.

Traditional production of VFAs from crude oil is unsustainable because of its environmental impact, therefore alternative solutions have been studied. The most promising solution has resulted in the VFAs production from organic waste based on biological processes thanks to the incoming environmental and economic benefits. In this scientific context, the state of current knowledge has not reached yet a satisfying level of comprehensiveness and it is mainly based on studies conducted at lab and pilot scale. Under the perspective to gain more knowledge and thus to promote an efficient as well as consolidated production of VFAs according to the key issues of the circular economy, a systematic and detailed study dealing with the impact of reactor configuration and relative operating conditions on biological VFAs production has been conducted. This step is a necessary condition to scale up the process and achieve its complete industrialization. According to this perspective and on the basis of the most recent findings from the international literature, the present review paper reports, as the main result of data elaboration, a novel one-to-one correspondence between organic wastes and reactor configurations having as target the VFAs yield enhancement.

Phosphogypsum (PG) is a by-product of wet process phosphoric acid production, mainly composed of calcium sulfate dihydrate (gypsum) together with some impurities. The annual accumulation rate of PG has reached 300 Mtons, and there is a need for an efficient, continuous, and bulk consumption strategy. Industrial by-products have been used as an alternative raw material for CO2 capture as a solid carbonate compound. PG is rich in calcium, being a promising candidate for CO2 mineral sequestration. In this manner, the Merseburg process (the ammono-carbonation of gypsum) allows both CO2 capture and PG recycling. Products are ammonium sulfate, a well-desired nitrogenous fertilizer and CaCO3, a functional filler material utilized in various kinds of industries. The Merseburg process allows dual environmental benefits by allowing the consumption of an industrial by-product and performing CO2 capture technology, both contributing to sustainable development goals. This study gives a brief summary of the environmental possible impacts of the Merseburg process in terms of CO2 sequestration and phosphogypsum management.

Those changes entail adjustments in drinking water treatment plant (DWTP) operations. Artificial intelligence (AI) has been used for modelling water quality for different purposes and has yielded reliable results. However, there has not yet been wide investigation of raw water quality modelling for treatment purposes using AI. For the first time, in this critical review, we analyzed AI models founded on machine learning techniques that are used for surface water quality modelling and which could be applied in the domain of source water treatment. In a novel approach, we convened an expert panel that helped us define the appropriate criteria for use in the selection of the papers for review. We analysed the selected papers according to several criteria, including the feasibility of input data generation, the modelled data applicability and the benefits and limitations. We evaluated whether the selected models could be applied to forecast raw water quality as decision support systems (DSS) in drinking water treatment. The highest rated were turbidity hourly models based on Support Vector Machines (SVM), as well as daily turbidity and pH models based on Artificial Neural Networks (ANN). We found there is a shortage of models used to specifically estimate raw water quality, which could assist in DSS at DWTPs. There should be an increased effort to model raw water quality, especially with AI models using hourly and sub-hourly time step.

Sustainable methods for treating drinking water such as biosorption are gaining popularity. The maximum permissible limits of most metal ions in drinking water are in the range from 0.003 to 2 mgL−1, however, the elevated concentrations in the range 0.01–2.5 mgL−1 are reported in contaminated waters in various regions of the world. Therefore, selecting the initial metal ion concentration range, and an optimum pH suitable for treating drinking water (pH 6.5–8.5) for laboratory experiments is a challenge for multi-ion biosorption studies. For the quantification of metal ions, ICP-MS is often used owing to its many advantages, however, the high operational costs of this instrument limits its use in research laboratories. Surface characterisation techniques such as TEM, NMR, ESR and related techniques are often ignored in biosorption studies although, these give valuable information pertaining to the mechanism of biosorption. Many theoretical models for explaining the biosorption mechanism have been proposed in the literature, one often contradicting the other. One of the major drawbacks of published biosorption studies is that too much emphasis has been laid on the theoretical explanation of biosorption mechanism and too little has been done to address the lack of practical application in terms of translatability of the methodology for commercial use. The present review highlights such issues while giving an insight on the processes, parameters and models used in biosorption reactions.

Here, we summarize and discuss new ways to improve the treatment of textile waste, including its utilization value and transformation ways, to help remediation and lower environmental impacts. This paper comprehensively expounds on the current situation of textile waste treatment and the recycling value of different types of textile waste. This includes recycling composite materials, fillers, energy materials and carbonized adsorption material, which support sustainable development with social and economic benefits. Overall, this shows that textile waste needs to be separated at large scales globally to reduce the carbon footprint, improve socio-economic benefits and mitigate environmental pollution. Otherwise, there is a risk that the global warming and ecosystem transformations, due to pollution and urbanization, could lead to severe adverse effects such as cancer and global pandemics.

These current management methods can result in adverse environmental effects, are expensive, and do not necessarily take advantage of the remaining energy potential in food waste. Alternative treatment technologies such as microbial fuel cells (MFCs) are an attractive disposal method since overall organic concentrations can be reduced, and some of the chemical energy of the food waste can be transformed into electrical energy. MFC research has focused on the use of liquid waste due to advantages such as easy handling, low internal resistance, and efficiency of ion transfer in the liquid phase. While some researchers have shown the potential of using complex solid waste as a direct fuel in MFC, there remain significant challenges for optimizing complex solid food waste-fed MFCs. In particular, the biological degradation of the complex substrates in food waste is a slow process and requires additional pre-treatment (physical, thermal, chemical, or biological) to degrade complex biopolymers efficiently. As such, this article aims to review the impact and importance of various pre-treatment methods for optimizing performance of food waste fed MFCs. It is clear that direct use of solid waste in MFCs can be promising if several factors are optimized, including the pre-treatment used, substrate biodegradability, and operational cost. Although low power output is one of the main obstacles in the commercialization of MFC, MFC can still be considered a viable, self-sufficient treatment method to treat waste with minimum to zero emissions.
