This study introduces #sewage sludge #biochar (SSB) into constructed wetland microbial fuel cell (CW-MFC) systems, enhancing #pollutantremoval and electrochemical performance. SSB’s conductivity and oxygen reduction activity, along with the enrichment of electroactive bacteria like #Geobacter, contribute to improved #wastewatertreatment and energy recovery. https://lnkd.in/gGGSDDH4

A study demonstrated the effectiveness of zinc-iron bimetallic oxide-modified walnut shell biochar (ZF@WBC) for removing lead (Pb(II)) from wastewater. ZF@WBC showed improved adsorption capacity through chemisorption, surface complexation, and ion exchange, offering a sustainable solution for heavy metal contamination and wastewater treatment. https://buff.ly/3A6ctxm #Biochar #Pyrolysis #CarbonCapture

#Explanation:Role of the Bioreactor Tank in MBR Technology. ##Biological Treatment: The bioreactor tank is where the biological treatment occurs. Microorganisms in the tank break down organic matter in the wastewater, reducing pollutants like Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). ##Membrane Filtration: The bioreactor tank is integrated with membrane modules (either submerged in the tank or in a separate unit). These membranes filter out suspended solids, bacteria, and other contaminants, producing high-quality effluent1. ##Enhanced Efficiency: Combining biological treatment with membrane filtration enhances the overall efficiency of the wastewater treatment process. It allows for higher biomass concentration and better pollutant removal compared to conventional methods2. ##Compact Design: MBR systems are more compact than traditional wastewater treatment systems because they eliminate the need for secondary clarifiers and tertiary filtration units.

𝗠𝗲𝗺𝗯𝗿𝗮𝗻𝗲 𝗕𝗶𝗼𝗿𝗲𝗮𝗰𝘁𝗼𝗿𝘀: 𝗞𝗲𝘆 𝗜𝗻𝗻𝗼𝘃𝗮𝘁𝗶𝗼𝗻𝘀 𝗮𝗻𝗱 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 𝗶𝗻 𝗪𝗮𝘁𝗲𝗿 𝗥𝗲𝗰𝘆𝗰𝗹𝗶𝗻𝗴 The global membrane bioreactor market size was valued at USD 3.35 billion in 2022 and is expected to grow at a compound annual growth rate (CAGR) of 7.0% from 2023 to 2030. 📊 𝐃𝐨𝐰𝐧𝐥𝐨𝐚𝐝 𝐒𝐚𝐦𝐩𝐥𝐞 @ https://lnkd.in/gD44RJEX A #Membrane #Bioreactor (#MBR) is an advanced #wastewater treatment technology that combines a #biological process, typically activated sludge, with membrane #filtration. It is widely used for municipal and industrial wastewater treatment, providing high-quality effluent suitable for reuse or discharge into sensitive environments. 🔷How it works: ➥Biological Treatment: Wastewater enters the bioreactor, where #microorganisms break down organic matter, converting it into carbon dioxide, water, and biomass. This process reduces pollutants in the water. ➥Membrane Filtration: After biological treatment, the #water passes through a #membrane_filtration unit, typically made of microfiltration or #ultrafiltration membranes. These membranes act as a physical barrier, allowing only treated #water to pass through while retaining suspended solids, bacteria, and other contaminants. 📊 𝐆𝐞𝐭 𝐭𝐡𝐞 𝐅𝐮𝐥𝐥 𝐑𝐞𝐩𝐨𝐫𝐭 @ https://lnkd.in/g8GAqR4B ➥High-Quality Effluent: The combination of biological degradation and membrane filtration ensures that the effluent is free from suspended particles and pathogens, making it highly suitable for water reuse. 🔷Key Benefits: ➥Compact design compared to traditional treatment systems. ➥Produces high-quality effluent suitable for recycling. ➥Reduces footprint and energy consumption.

This research explores #greenchemistry principles by employing #tangerine peel-derived #biochar as an anodic catalyst for sulfur dioxide (SO2) electro-catalytic oxidation. The study optimizes TPB/CNT-derived Fe3C/Fe/C (N-doped) catalyst, demonstrating cost-effectiveness and eco-friendly potential in simultaneous #SO2removal and hydrogen production, contributing to sustainable flue gas purification. https://lnkd.in/gCkt7-xU

Ammonia production could be decarbonised – and water pollution mitigated – with a reactor design developed by engineers at Rice University, Texas. In a study published in 'Nature Catalysis', Rice engineers led by Haotian Wang described the development of a new reactor system that converts nitrates into ammonia, a chemical used in fertilisers and a range of industrial and commercial products. Ammonia is one of the most widely produced chemicals globally, with worldwide demand surpassing 180 million tons annually.

This study examines biochar production from palm oil empty fruit bunches using mechanical-press torrefaction. Varying temperatures and pressures enhanced carbon content and energy yield. Higher pressure and temperature improved biochar quality, making it suitable for energy and environmental applications. https://buff.ly/4fbC5aW #Biochar #Pyrolysis #CarbonCapture
