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. Yes No



What alternative treatment options are being considered?
