WWTU
All water that goes to the anaerobic system goes to the biox system.
Benzene is difficult to treat  -  no "handle." Also a surrogate for combustion.
Amount of water from process is fairly small to overall volume (e.g. groundwater). Total discharge over 132 million gallons/year total.  Water from stormwater and process water just over 16 million gallons.
All spills go through an organic separations process (decant tanks). Have conductivity meters and other sensors to indicate phase boundaries  -  pump only aqueous waste to a second separations.
