RDP Enhanced Pasteurization System

1Dewatered Biosolids are continuously loaded into the Storage and Feed Hopper

2Biosolids are metered into the sequencing batch Pasteurization Reactor, just enought lime is added to achieve
pH > 12

3Biosolids are heated in the sealed Pasteurization Reactor. Time, temperature, and chemistry are all variables to produce:

aOptimize Pasteurization

bMinimize offensive odors

cDried to a friable form that is easily to handle and not dusty - typically 55-65% dry solids

dProduce a more nutrient-rich end product

4 The end product is stable due to a nominal amount of lime and will remain stable despite the possibility getting wet. It will wash into the soil after a couple of wet weather events
