Description:

Stripping, which effectively removes VOC's from wastewater is being used to remove organics (mostly dichloromethane) from a 30-50 gpm wastewater stream. The stripped organics are treated in our RCRA permitted incinerator and the remaining wastewater is treated in our NPDES permitted biotreatment system after testing for organic content. The facility consists of two pretreatment storage tanks, a stean stripper and two post treatment storage tanks.
