Summary: The study found that three fungal species, Ganoderma lucidum, Pleurotus ostreatus, and Penicillium restrictum, could reliably flocculate and harvest 62-75% of microalgae without damaging them. The ratio of fungi to algae had significant but contrasting effects on harvesting and settling, with the optimal ratio being 1:2 to balance the needs for both. The application of fungal filaments to microalgae in suspension produced readily settling flocs and was less time-consuming, making it an attractive method for harvesting microalgal biomass for low-value products.

Summary: The use of a magnetic field combined with coagulation and flocculation proved to be an effective method for enhancing the dewaterability of municipal and citric acid-processing waste-activated sludge. The effects of the magnetic field varied depending on the sludge properties, with different changes observed in particle size, zeta potential, and viscosity for each type of sludge.

Summary: A comparative analysis of three assisted advanced oxidation processes was conducted to study their efficacy in enhancing tannery chemical sludge dewaterability. The Fe2+/(NH4)2S2O8 process was found to have the greatest impact on breaking down sludge cells and releasing chromium, organic carbon, protein, and total dissolved solids. The study also revealed a two-step mechanism of oxidation followed by coagulation in improving sludge dewaterability.

Summary: This study introduces the use of filamentous fungi in microalgae-based wastewater remediation for biomass harvesting and utilization. The research progresses of co-cultivation of fungi and microalgae, fungi-assisted algae harvesting, and the mechanisms and key parameters of fungi-assisted microalgae harvesting are discussed. It also provides an in-depth discussion of co-cultivating filamentous fungi and microalgae in wastewater for nutrient removal and biomass collection. Additionally, it introduces some high-value components important for the economic benefits and industrial application of harvested algal-fungal biomass.

Summary: The research focused on utilizing baker's yeast wastewater for producing protein-rich fungal biomass and biogas, while removing COD and nutrients. A. oryzae was found to be effective in biomass production, and anaerobic digestion showed satisfactory COD removal. The results demonstrate the potential of resource recovery from baker's yeast wastewater through biorefinery processes.

Summary: Tertiary wastewater treatment with microalgae using bio-flocculation instead of mechanical harvesting has shown high efficiency and wide applicability, which is crucial for enhancing technological competitiveness. In initial experiments, harvesting microalgae from wastewater resulted in removal efficiencies of 73-93% within 24 hours and up to 95% within 48 hours. The cost-effective and environmentally sustainable bio-flocculation technology has significant importance in reducing operating costs.

Summary: Filamentous bulking and foaming are common settling problems in activated sludge wastewater treatment plants. These problems negatively affect the quality of the final effluent and have environmental, human health, and economic implications. Traditional control methods are often ineffective, and non-specific methods like chlorination can harm important bacterial species. This review discusses the filamentous bacteria responsible for bulking, their global distribution, and control strategies, highlighting the need for further research.

Summary: In this study, a modified microalgal-bacterial granular sludge (MBGS) was constructed and compared with aerobic granular sludge (AGS) for treating 1%-5% saline wastewater. It was found that MBGS showed better performance in terms of granule stability and salt resistance at 1% salinity. The presence of filamentous algae including Leptolyngbya and Geitlerinema enhanced biomass content and lipid production. This study provides valuable information for the practical application of MBGS technology.

Summary: The study investigated the effect of temperature on the microbiome of a submerged membrane bioreactor treating hospital wastewater, finding that the maximum removal of pollutants occurred at 20 degrees Celsius. Low temperatures inhibited the removal of certain pharmaceuticals. Microbiome analysis revealed a decrease in nitrifying bacteria and ciliate populations at lower temperatures, with an increase in fungal groups.
