Veolia’s hydrolysis pasteurization digestion (HPD) process enhances anaerobic digestion with over 80% conversion of COD to biogas and production of a nutrient rich, high quality digestate. Pasteurization Enhance digester efficiency with Veolia’s hydrolysis pasteurization digestion process Foaming is virtually eliminated because nocardia bacteria, the typical cause of digester foaming, is destroyed in the thermophilic stage.Total hydraulic retention time is greatly reduced, which means smaller digesters can be used and associated costs are lower.It can handle contamination levels up to 30%, and captures over 95% of the organic material.ĭownload 2PAD anaerobic digestion brochure (PDF) Veolia’s Re:Sep biowaste separation system maximizes organics capture and produces a clean high quality slurry. Mechanical separation to produce high quality slurry Tab 1 Body Copy: Biowaste separation provides an integrated, multi-step process that provides enhanced organics capture, effective removal of contaminants and grit, producing a clean easily digestable slurry. Produces class A biosolids, which are bio-safe and can be land-applied without restrictions Separating the acid- and methane-forming phases makes the digestion process more efficient and more effective Aeration is not required, so energy costs are low Veolia’s digestion enhancement delivers higher conversion of volatile organic matter, with over 80% COD converted to biogas while providing shorter retention times and increased capacity within the digester for additional sludge or organic waste digestion. Veolia’s advanced anaerobic digestion technologies use bacteria in the absence of oxygen to break down matter to create biogas. High efficiency separation of contamination and grit improves digester performance and results in: Digestion High efficiency digestion It can handle contamination levels up to 30%, and captures over 95% of the organic material.ĭownload biowaste separations fact sheet (PDF) Separation Mechanical separation to produce high quality slurryīiowaste separation provides an integrated, multi-step process that provides enhanced organics capture, effective removal of contaminants and grit, producing a clean easily digestable slurry.

Rather than disposing of organic food waste to landfill, Veolia’s biowaste solutions can be used to recover biogas while producing nutrient rich fertilizer cake. Organic material contained within leftover food waste collected from homes, from food manufacturers and restaurants represents a significant sustainable energy source.

Why Does Veolia Provide Biowaste Solutions?īiowaste or food waste is increasingly regarded as a resource instead of a waste requiring disposal.
