Removal of dissolved sugar (corn syrup) from waste water

[cbates@max.state.ia.us (Cherrie Bates)]

Our pollution prevention team is trying to help a local business.  Here
is the problem.

Waste Water Constituents: Corn syrup 70%, casanate(milk protein) <3%,
Oil, 0.5% salts.

Current system:
10,000 gallon accumulator===Adjust pH to neutral here

Pumped into samller tank(50)=	Adding ferrous chloride and a fat emulsion
polymer as it is going into the tank.   pH drops to 5.1

In the tank they add a coagulant.  

Water flows to a larger settling tank (5,000 gal). Settled material is
pumped into tanker, float is skimmed and pumped into tanker.They are
also pulling water off the tank and recycling it through the tank again.

They will be adding a dissolved air unit in the next week.

Here are their parameters

BOD:  675.8 lbs/day (30 day avg.)
      1035 lbs/ day (daily max.)

Their system was designed for 4000 gal/ hr, they are currently running
at 1000 gal/hr. 

These levels are way above their permit.  They need to reduce by 20%.	 

Additional note:  They want to double size of facility this year.  So
the water volume will probably double too.  I have toured the facility.
They are using dry clean operation in 85% of the facility.  Some
sterilization requires use of water.

I would greatly appreciate any help ASAP. Report due in 2 weeks.
