Introduc)on

In  1992,  Chrysler  chose  Permaflow  tubular   ultrafiltraCon  to  be  used  in  a  wastewater  recycling  system  for   their   engine  plant  near   SalCllo,  Mexico.    The   system  supplied  was   a  tubular  Permaflow  membrane  bioreactor  (MBR)  followed  by  reverse  osmosis  polishing.  The  system  was  designed  to  allow  Chrysler   to  treat   and  recycle  the  oily  effluent  from  their  facility.

Performance   of   this   facility  has   been   excellent   meeCng  Chrysler‘s  needs   for   treated   water   quality.     Of   equal   importance   is   the  membrane   lifeCme   which   has   been   demonstrated   to   be   over   ten  years,   exceeding   all   esCmates.   This   plant   uses   a   SCADA   based  system  that  allows  remote  monitoring  of  the  facility.

The  Solu)on

With  a  tubular   Permaflow  MBR,   even   the   most   difficult   industrial  wastewater   streams  can   be  treated   reliably  and   with   superior  effluent  quality.    In  fact,  the  final  effluent  quality  is  so  high  that  many  industries  are  recycling  the  treated  water  within  their  faciliCes  creaCng  a  closed  loop  of  water  use  and  treatment  and  recovering  up  to  90%  of  their  water.

The   tubular   Permaflow   MBR   employs   tubular   ultrafiltraCon  membrane   technology   as   the   solid   liquid   separator   that   ensures  the   highest   quality   effluent   and   the   most   efficient   and   effecCve  treatment.  The  MBR   effluent  can  be  directed   to  a  spiral  RO  system  without  fear  of  fouling.

Process  Overview

Oily  effluent   from  the  Chrysler   facility  is  pumped  to   the  bioreactor  and   mixed   liquor   is   then   sent   to   two   UF   units,   each   with   45  Permaflow  membranes.

Biomass   from   the   bioreactor   passes   through   the   inside   of   the  tubular   membranes   under   pressure.   Clean   water   is   able   to  penetrate  through   the  membrane  wall   and   is   collected  within   the  membrane   housing   and   ulCmately   discharged   as   clean   effluent.  The   permeate   is   then   sent   to   a   down-­‐   stream   RO   system   for  polishing  before  being  reused  within  the  facility.
