2021 – Wastewater Treatment & Resource Recovery of Sewage Sludge

BG+ is a simple absorption column designed to reduce the Hydrogen Sulfide in Biogas while also completely purging the Iron Chloride from the sludge. With this small device installed into the Sludge Treatment facility, we estimate that approximately 26% of the Hydrogen Sulfide can be eliminated from the biogas before entering the desulfurizer, significantly reducing operating costs and the desulfurizer’s workload.

Currently, FeCl3 are used to dehydrate sludge from anaerobic digestion. FeCl3 is combined with SO42- and S ions in Sludge to form FeS Fe2S3, which exists in solid form in the sludge.The use of FeCl3 reduces odor by suppressing the generation of H2S in the form of a gas.

Welcome to SludgeX, a startup team of bright master’s students from around the world with the goal of optimizing the sustainability of wastewater treatment plants around the world! Our short 3 minute video will introduce you to our vision, then you can read details about how we envision the start of our journey towards changing the way we think about how sludge can be managed in a sustainable future.
