Description

HRP was retained to evaluate the discharge requirements that client must meet for 1,4 dioxane are governed by the facility’s National Pollutant Discharge Elimination System (NPDES) permit and required the facility to attain compliance with the 1,4 dioxane permit limit in a three phased manner. 

The key production processes at Facility consists of esterification, polymerization, batch processing, continuous processing, and staple spin/stretch processing.  These processes are used to manufacture polyethylene terephthalate (PET) polymer or chips, and PET staple fiber.  HRP’s reviewed the process chemistry and recommended various water conservation and segregation measures such as follows to reduce the overall 1,4 Dioxane concentration in the effluent wastewater.   

HRP further worked with a multi-disciplinary team of facility members, sub-consultants, and contractors to:

  • Conceptualize and scope several treatment methods such for client’s consideration and approval
  • Front End Engineering Design Package for a new Distillation Column and other wastewater equipment
  • Developed detailed engineering specifications for the project
