Sludge on the road for wastewater treatment? According to the World Bank, around 80 percent of the world's wastewater is discharged into the environment without adequate treatment. Wastewater treatment works (WWTW) are built to address this and treat wastewater before it is released back into the environment. However, over time, conventional wastewater treatment methods have more or less not changed. The treatment process typically involves four stages and integrates physical, chemical, biological, and combined technologies. Currently, novel solutions are being developed and commercialized, mainly targeted at the secondary and tertiary treatment phase, including approaches such as membrane bioreactors (MBRs), advanced oxidation processes (AOPs), and constructed wetlands as a nature-based solution. Furthermore, enhanced resource recovery of energy and nutrients (e.g., nitrogen; phosphorus) from sludge is explored via approaches such as anaerobic digestion (AD) for biogas production, microbial fuel cell (MFC) technology for electricity production, and struvite precipitation for phosphorus recovery. For these solutions, some headwinds are on their way. In the US, the Biden-Harris administration recently announced nearly $6 billion for clean drinking water and wastewater infrastructure, and water treatment and conservation startups raised $787 million in 2023, more than double the $343 million total funding raised in 2019, with companies such as Gradiant ($225 million Series D) and Allonnia ($30 million Series A) leading the stage. Still, enhancements in, among others, industry adoption timelines, government regulations, funding environments, and approval processes are needed for widespread industry implementation. → Dive into advanced wastewater treatment works (WWTW) with our latest Insights piece: https://t.ly/6iTR_ #WWTW #wastewater #climatetech #deeptech #deepsense #techduediligence #expertnetwork

We are thrilled to share our latest publication in IWA Publishing's "Water Science & Technology"! 🌍💧 An innovative #CircularEconomy system has been implemented at the Brunswick wastewater treatment plant, leading to remarkable improvements over four years: ✅ Methane production increased by 18% ✅ Digestate dewaterability improved by 14% (+3% dry matter) ✅ High phosphorus recovery rates of over 80% from filtrate ✅ Nitrogen recovery as ammonium sulfate at 85–97% from filtrate While refractory COD concentration increased by 4 mg/L, the effluent still met legal standards, and the secondary fertilizers showed low pollutant content, minimizing risks to ecosystems. Overall, we’ve seen a decrease in the plant's carbon footprint due to enhanced biogas production, renewable fertilizer recovery, and reduced nitrous oxide emissions. Transitioning to green energy is key to achieving #CarbonNeutrality! 🌱✨ Read more about our findings here: https://lnkd.in/ewvCSKtd International Water Association

🏔 **Leachate Treatment Using Algae** 🌏 #Leachate is a liquid passed through #solid waste, extracting dissolved and suspended materials. It is a major #environmental concern due to its high concentration of pollutants, including #heavy #metals, #organic compounds, and #pathogens. Conventional #leachate treatment methods, such as #physicochemical and #biological processes, are often expensive and #energy-intensive. #Algae-based leachate treatment is a promising alternative that offers several advantages over #conventional methods. #algae have a high capacity to absorb and accumulate #pollutants from wastewater. #algae can also be used to produce biomass for bioenergy. #algal #biomass can be used for the production of bio-#fertilizer, bio-#feed or other valuable products. Overall, #algae-based leachate treatment is a #sustainable and #cost-effective technology that has the potential to significantly reduce the environmental impact of leachate from landfills and other waste disposal sites. At TRINITY INTERNATIONAL we are employing the potential of #algae to treat Leachate waste.

Let's turn waste into treasure! Our environmental innovation that turns waste into valuable resources. This microwave vapor plasma process does not produce NOx, CO, CO2, SO2 gases, plus the emission is odorless
Revolutionary waste conversion into environmentally friendly fuels without wasting water. There are no NOx emissions and no waste water is produced. With an investment of a few tens of thousands of dollars, we created the entire vertical of the possibility of small-scale waste processing for poorer countries. There are no NOx emissions during gasification in water vapor microwave plasma. NOx has a harmful effect on health and the environment, NO2, for example, is 40 times more toxic than CO. It can be produced from waste by pyrolysis in an oxygen-free space a) clean coal for baking and cooking, b) oil for the heating and diesel for the car engine c) diesel or syngas fuel for GENSET (for village electricity) The main advantage of steam plasma reactors is that there is no nitrogen in the steam plasma, the plasma reactor, the gasifier and the plasma afterburner chamber, so there is no nitrogen dioxide (NO2) and nitrogen oxides (NOx). The hydrogen introduced into the reaction space with the steam plasma slows down the reactions of gaseous sulphur, phosphorus and free chlorine formation, i.e. gases that are difficult to remove in the gas purification unit. manufacturer www.gumienergia.hu

Could your wastewater treatment be releasing more GHG emissions than you thought? 🤔 A recent Princeton study found that municipal treatment facilities were releasing nearly double the methane emissions than previously thought. The culprit - biogas production from anaerobic digesters. Why does this matter for our industrial users? Most industrial wastewater treatment relies on anaerobic digesters, meaning these emissions contribute to your Scope 1 if you have an onsite digester, or your Scope 3 if discharging to sewage. ☁️ While the study focused on municipal plants, a similar industrial study could be on the horizon. Stay proactive in reducing emissions by exploring our methane-free treatment system.
