Municipal Wastewater Treatment

Conductive Material to Enhance Organic Waste Biodegradation
Anaerobic digestion (AD) is a biological method widely used to treat wastes and wastewater containing high levels of organic matter in the absence of oxygen to convert chemical energy in organic carbon to biogas. With AD, the waste volume can be reduced drastically with green energy generation simultaneously. In practical applications, complex structure or toxicity of substrates often impair AD performance associated with low degradation rate and unstable biogas production. Electron transfer among different guilds of microorganisms is the rate-limiting step of AD process, and it is also the basic reason behind the deteriorated AD performance. This technology relates to the dosing of conductive materials which can facilitate interspecies electron transfer and improve the overall metabolic activity in anaerobic digestion. In addition, it is a green and cost-effective technology as those selected materials (e.g. biochar, activated carbon, and iron scrap) can be readily obtained from nature or produced from wastes and recovered for repeated use. The technology provider is looking for waste and wastewater biological treatment providers to license and commercialize this technology.
