Biosolids Drying or Energy Recovery
BioCon™ dryer is a dual-belt convective air dryer designed to be one of the safest on the market. Low operating temperatures allow the process to utilize a variety of waste heat sources, such as the easily added BioCon Energy Recovery System (ERS), or BEES BioCon Energy Exchange System.
Batch Thermal Hydrolysis Process
Bio Thelys™ process is an anaerobic digestion system enhancement. The use of low pressure and low temperature steam applied to dewatered biosolids causes the microbial cells to rupture and therefore increases the soluble fraction of COD that is available for digestion. This increases both the rate at which digestion occurs and the amount of solids that will be reduced; the net result being greater biogas production.
Continuous Thermal Hydrolysis Process
Exelys™ is a continuous thermal hydrolysis system. Each treatment train uses one reactor with progressive cavity pumps that hold the biosolids at the required pressure and temperature for thermal hydrolysis for the required amount of time in order to meet Class A requirements.
Efficient Phosphorus Recovery
Struvia™ prevents uncontrolled struvite precipitation during wastewater treatment. This Veolia process uses a patented mixing system, TurboMix™, to produce and separate struvite crystals within a single reactor. Struvia™ is compact, resourceefficient, and produces a granular end product consisting of magnesium ammonium phosphate (MAP) crystals.
Biosolids Solar Drying
SOLIA™ Veolia has enhanced the efficiency of solar sludge drying by coupling two well-known processes: air drying and aerobic fermentation. Using solar radiation and the action of an automated windrow turner (SOLIA™MIX), water evaporates from the sludge for subsequent removal from the greenhouse.
