Dear Carlos,

As you know, in any wastewater treatment application the bulk of the work has to be done by bio filtration.

If you have considerable colour problem, you should probably see if you could optimize or improve your bio filtration system.

If you like I will gladly give you some good ideas how to improve efficiency of your bio filtration and aeration.

The better and the more effective is your bio filtration the less expensive will be the polishing and colour removal system, using oxidizers as ozone and the whole project will be more economical.

Mechanical micro filtration is typically way too expensive as far as energy consumption is concern to be used in wastewater treatments.
