Objectives and General Questions

What is the objective of an Alken Clear-Flo® or Alken Solutions polymer program?

(improved recovery, system stability, nitrification, improved startup, sulfide control, improved organic removal, flocculation etc.)

_________________________________________________________________________

What criteria would determine the success of the program? Time frame?

________________________________________________________________________

_________________________________________________________________________

What are the justifications for an Alken Clear-Flo® or Alken Solutions polymer program? (reduced operating costs, reducing environmentally related complaints, compliance, avoiding fines, etc.)

__________________________________________________________________________

If necessary, can system improvements be effected? (such as waste dilution, process control changes, nutrient amendment.

__________________________________________________________________________

What alternative treatment options are being considered? Have bacterial treatment products been used in the past or presently? (Brand, formula designation and dosage?)
