A recent study reveals that while wastewater treatment plants effectively remove 99% of microplastics and some PFAS from water, these contaminants accumulate in biosolids, which are often used as fertilizer on farmland. This practice reintroduces pollutants into the environment, highlighting the need to reduce microplastic and PFAS production at the source.

Excellent research making biochar from sewage waste... also it appears PFAs are burnt off in pyrolysis at 700/800 degrees. With such polluted rivers in the UK with the will to improve, technically it can be done.

Industrial processes produce significant amounts of harmful waste, with about 48% of global wastewater released untreated. Industries such as chemical manufacturing, textiles, and food processing are major contributors to this issue, necessitating stringent wastewater treatment practices. Effective on-site treatment not only protects the environment but also ensures operational continuity and compliance. Discover how these industries can implement affordable and sustainable wastewater solutions to mitigate their environmental impact.

Gradiant is proud to announce the launch of ForeverGone, the industry’s only all-in-one solution to permanently eliminate PFAS from municipal and industrial water. Unlike current technologies that merely transfer these harmful substances, ForeverGone eliminates PFAS completely and permanently. Combining Micro-Foam Fractionation and the Destruction Engine, this system meets and exceeds the latest US EPA drinking water standards for #PFAS. By eliminating the need for waste handling, transportation, and disposal by landfilling or incineration, ForeverGone sets a new standard for simplicity, efficiency, and sustainability in water treatment. Prakash Govindan, COO of Gradiant, said, "ForeverGone is different from anything in the marketplace – it completely solves the challenge of PFAS contamination. Our integrated technologies remove and destroy PFAS from drinking water and wastewater in one unit, whereas existing options merely displace the problem from one medium to another. ForeverGone is precisely the disruptive innovation the industry has been calling for." Explore how ForeverGone is pioneering a cleaner, safer future.

💥💥💥 💦♻️ Reimagining industrial wastewater treatment as a resource recovery opportunity is the future! By utilizing non-toxic alternatives like rare earth-based coagulants the #foodandbeverageindustry can realize several environmental and financial benefits. Firstly, avoiding traditional coagulants prevents the concentration of harmful substances like aluminum or ferric in sludge, reducing negative impacts on ecosystems during disposal... Using Rare Earth-based coagulants enhances treatment performance is particularly beneficial for discharge requirements like phosphorus removal. This not only ensures compliance with environmental regulations but also contributes to improved water quality and reduction in chemical usage. The 3+ charge of rare earth ions is advantageous because it provides a strong positive charge, allowing for efficient precipitation and removal of phosphates from the water. This characteristic, combined with the ability to operate effectively over a wider pH range, makes rare earth-based coagulants more versatile compared to alum or ferric-based alternatives. In addition, the 3+ oxidation state of rare earth-based elements contributes to their effectiveness in releasing water better than alum or ferric, resulting in an immediate reduction of sludge volume by more than half! By capturing valuable components from wastewater through innovative treatment methods, the food and beverage industry can turn what was once considered waste into a valuable resource. This shift from degradation to recovery aligns with sustainable practices, positively impacting the environment. Moreover, the reprocessed materials can be utilized or sold, turning what once was an operational cost into a potential revenue stream for the facility. Adopting non-toxic alternatives in wastewater treatment not only minimizes environmental harm but also transforms a potential disposal issue into a cost-effective resource recovery opportunity for both the environment and the bottom line of the food production facility. #revolution #americanmanufacturing #USA #SustainableFood #wastewatertreatment #wastewatermanagement #GreenTech #rareearths #environmentalcompliance #sludgedewatering #sludge #ResourceRecovery #CleanWater #plantmanager #EcoFriendly #environmentalmanagement #CircularEconomy #waterefficiency #PhosphorusRemoval #RareEarthCoagulants #watermanagement #WaterQuality #conservation #GreenProduction #ZeroWaste #wetlandsmatter #EcoIndustry #beef #porkproduction #SustainablePractices #FoodTech #watershed #GreenBusiness #petfoodindustry #EnvironmentalImpact #WaterManagement #poultryindustry #PhosphorusCapture #InnovationInIndustry #seafoodindustry #WastewaterTreatment #SustainableSolutions #GreenManufacturing #CircularProduction #sustainableagriculture

Waste-to-Energy (#WtE) plants are highly effective at destroying Persistent Organic Pollutants (POPs), a new UK government study found. WtE facilities sampled in the research achieved destruction efficiencies that exceeded expectations, demonstrating a strong ability to manage POPs and fulfil international commitments. POPs “are organic substances that persist in the environment, accumulate in living organisms and pose a risk to our health and the environment,” according to the European Chemicals Agency (ECHA). The POP category includes pesticides, dioxins, and industrial chemicals such as those found in electrical equipment. The analysis underscores WtE's importance in reducing the presence of harmful chemicals in the environment, reinforcing its role as a cleaner, energy-generating, and materials-saving alternative.

today's #cyclodextrin: C&EN's recent paper on #PFAS removal out of #drinkingwater features cyclodextrins too among other solutions. The Chicago-based water purification company Cyclopure is looking beyond traditional activated carbon and ion-exchange resins. It uses β-cyclodextrins made from plant-based products like corn and potato starch to remove PFAS from water. For the past 4 years, the company has been optimizing conditions for polymerizing, purifying, and granulating β-cyclodextrins, which it purchases in bulk from WACKER. The plant-based sorbent, sold under the name Dexsorb, has a high capacity for PFAS, it takes up less space than GAC and can be regenerated. Today, Cyclopure provides various industrial and consumer solutions with their technology Public water utilities in the US are facing a 5-year deadline to meet low parts-per-trillion limits for six per- and polyfluoroalkyl substances (PFAS) in drinking water. The Environmental Protection Agency estimates that thousands of water systems will need to install advanced treatment processes to meet the limits. Utilities are eyeing several technologies to remove PFAS, including ion-exchange resins, granular activated carbon, and plant-based sorbents. But eventually they will need to replace such media, and what to do with the PFAS-laden spent media becomes the next challenge. Sustainability goals, concerns about liability related to PFAS in waste, and potential supply chain issues from soaring demand for PFAS removal media are pushing companies to develop methods for regenerating spent media and destroying the PFAS. But it’s unclear how water utilities will pay for technology to remove PFAS from their drinking water, as well as what the cost of replacing and disposing of media will be.

PFAS is a group of synthetic "forever chemicals" (so called because they're difficult to break down) that bioaccumulate in living organisms. 🧪🚰 #PFAS can leach into drinking water aquifers and regulating and controlling them has become a priority for the EPA. Check out our blog article that dives into PFAS: what they are, how they're regulated, what this means for your projects, and how Dudek can help. https://bit.ly/3T43QbK
