RE: latex in wastewater

This could be similar to permitting a discharge from water-curtain paint
spray booths, which may add polymer to settle captured paint solids.

Subject: latex in wastewater


I recently received a call from a POTW who is trying to determine
pretreatment permit limits for a company applying a latex coated fabric to a
foam backing.  The excess latex is washed off the fabric and ends up in the
discharge.  The POTW has experienced some problems with blockages in the
past but not recently.  The effluent is also extremely high in BOD / COD.
Presently the company only discharges about 2000 gpd but they plan a future
expansion and thus the POTW is trying to assess what limits, pretreatment
equipment, and waste management practices should be imposed / required.

Does anyone have experience in: permitting a similar company, the  types of
limits imposed, types of operational practices required, experience with
blockages or other problems.

I am aware of some companies who have used a clarifier with a filter press
to treat this type of waste stream.

Thanks in advance
