What are the limitations and problems or cost for these struvite based technologies for treating food digestate?
Best insight from top research papers
Struvite-based technologies for treating food digestate have some limitations and cost considerations. One limitation is the potential for scale formation at the cathode surface, which can block catalytic active sites and limit extended operation . Another limitation is the inhibition of microalgae growth by high ammonia concentrations and low light transmittances, which affects the efficiency of microalgae-based systems for digestate treatment . In terms of cost, the use of platinum (Pt) electrodes in microbial electrolysis cells (MECs) can be expensive, but low-cost alternatives such as stainless steel mesh (SSM) cathodes have shown similar performance . Additionally, the cost of adding magnesium chloride (MgCl2) or seawater bitterns for struvite precipitation in crystallization devices should be considered . Overall, while struvite-based technologies offer potential for nutrient recovery from digestate, these limitations and cost considerations need to be addressed for their widespread implementation.

How digestate from OFMSW from paper component was used as biofertilizer?5 answersDigestate from the organic fraction of municipal solid waste (OFMSW) was utilized as a biofertilizer in various ways. The digestate was found to have a fertilizing effect on nitrogen nutrition similar to mineral fertilization, showcasing its potential to reduce synthetic fertilizer use. Additionally, technologies for dewatering digestate were explored to enhance its commercial value and eco-friendliness, with the production of granular fertilizers proposed as a method to increase efficiency and recycling of phosphogypsum. Furthermore, studies highlighted the nutrient-rich nature of digestate from agricultural biogas plants, emphasizing its high nitrogen content and suitability as a multi-component fertilizer for agricultural use. The biofertilizer potential of digestate was further supported by the presence of beneficial soil bacteria like Clostridium and Pseudomonas, known for nitrogen fixation and phosphate solubilization.
Which has a higher C:N ratio digestate or slurry?4 answersThe C:N ratio is higher in digestate compared to slurry. Digestate, a byproduct of anaerobic digestion, contains valuable nutrients but relatively little organic matter. Studies show that digestate treatments do not significantly impact soil organic carbon (SOC) and total nitrogen (TN) levels. In contrast, slurry contains more organic matter but has a high water content, making its management expensive. Additionally, the application of digestate with straw increases microbial biomass C significantly. Furthermore, digestates applied to different soils result in varying carbon (C) and nitrogen (N) dynamics, with higher C emissions in sandy soils compared to silty soils. Overall, digestate generally exhibits a higher C:N ratio compared to slurry, indicating a difference in organic matter content between the two fertilizers.
What are the current challenges and limitations associated with implementing water technology solutions to address global water scarcity?4 answersThe current challenges and limitations associated with implementing water technology solutions to address global water scarcity include the strain on natural resources due to climate change, population growth, and rising standards of living. Water scarcity risk, which includes local water scarcity risk and virtual water scarcity risk, poses a significant economic challenge to sustainable development. The traditional water stress index used in existing assessments is limited in accuracy and descriptiveness. Competition for freshwater resources intensifies water scarcity, and addressing this challenge requires incentives for sustainable water use. Efforts to bridge the gap between potential and implementation of water conservation technologies are needed. Additionally, the economic value of water usage is lower in some regions, and the scalability and economic feasibility of novel technologies for sustainable water management need to be considered. These challenges highlight the need for comprehensive strategies that encompass conservation, wastewater treatment and reuse, desalination, infrastructure development, and international cooperation.
Nutrient recovery system from sludge?4 answersNutrient recovery systems from sludge involve the use of advanced treatment technologies to manage biosolids waste and maximize the recovery of phosphorus. One approach is the wet oxidation (WO) process, which can achieve high removal values of organic matter and total solids content. Phosphorus can be recovered from the liquid effluent of the WO process through chemical precipitation as struvite, a slow-release fertilizer. Another method involves the use of an anaerobic unit before the pre-dewatering stage to favor the early release of phosphorus and minimize uncontrolled struvite precipitation. Implementing a phosphorus stripping unit can enhance phosphorus recovery and reduce the phosphorus content of biosolids. Struvite precipitation can also be achieved using a fluidized-bed reactor, with high performances even at short hydraulic retention times. The presence of volatile fatty acids does not adversely affect struvite precipitation performance. Co-composting wastewater treatment plant sludge with municipal solid wastes can also be used for nutrient recovery, with optimal ratios of waste to sludge, aeration periods, and porous material content.

What are the challenges in the management of residual sludge from biological treatment?4 answersThe challenges in the management of residual sludge from biological treatment include the presence of pathogenic microorganisms, heavy metals, and emerging pollutants, such as antibiotics and disinfectants, which pose risks to human health and the environment. Additionally, there is a need for efficient inactivation of pathogens to ensure safe disposal and reuse of the sludge. Increasing the solids retention time (SRT) in wastewater treatment plants (WWTPs) to minimize sludge wastage can lead to problems such as excessive sludge accumulation, changes in nutrient ratios, and insufficient treatment. Ecotoxicity assessment of water treatment sludge (WTS) is still scarce, and there is a lack of consensus on the most representative/sensitive species for evaluating WTS toxicity. Biological stabilization processes may not completely remove pollutants and pathogens, necessitating further treatments to improve the quality of biosolids and ensure their safe use. The presence of emerging pollutants in sludge has led to limitations on traditional disposal routes and increased process costs, driving the investigation into sludge-embedded resource recovery through biorefinery processes.
