Separate solids from liquids

What makes Octipole a more environmentally friendly option compared to traditional clarifiers? *

It requires no mixing or activation

It contains no sugar derivatives

It is made of eight biodegradable chemicals

It only works on cane sugar

What is the correct procedure for activating Octipole? *
