Veolia Water Technologies products

Enhance digester efficiency with Veolia`s hydrolysis pasteurization digestion process. Veolia`s hydrolysis pasteurization digestion (HPD) process combines all of the stages of an effective digestion process into an integrated approach that can be tailored based on plant capacity to help maximize the conversion of these wastes into value products, namely renewable energy and fertilizer. The hydrolysis pasteurization digestion process enhances anaerobic digestion with over 80% conversion of COD to biogas and production of a nutrient rich, high quality digestate.

High efficiency mixing for anaerobic digestion. Trends in anaerobic digestion aim to reduce retention time and increase dry solids concentrations, raising organic loading and improve efficiency. With increased organic loading of digesters, mixing becomes critical to ensure the whole digester volume is available for processing; fresh feed material is mixed uniformly within the reactor; and the biological breakdown products of digestion are dispersed

Store and upgrade raw biogas to methane grid quality. Veolia provides solutions for biogas management with the TECON* Double Membrane Gasholder and the MemGas* gas upgrading system. TECON is used for any application that needs gas storage such as municipal wastewater treatment plants with anaerobic digestion, landfills with biogas usage, industrial wastewater treatment plants, agricultural energy recovery facilities, etc. MemGas upgrades raw biogas to renewable natural gas for pipeline injection with more than 99% methane recovery. This provides a reliable revenue source. *Trademark of Veolia; may be registered in one or more countries.
