Can I use aluminum as construction material for a hydraulic channel flocculator in water treatment plants? Usually the water has about 3.0 to 5.0 of chlorine units and it is slightly corrosive.
Have an insight or suggestion?

Re: Using Aluminum in Water Treatment Plants27 January 2009 at 1:29pmAluminum is attacked by both acids and bases. Referring to the chapter "Corrosion in Wastewater Systems" in ASM Vol. 13C: Corrosion in Specific Environments, on page 25 it says "...Aluminum is not recommended for use in fluid exposures, due to the wide range of pH values found in wastewater facilities.” Based on this, I would advise against using aluminum in your application.
