Hi Ali.

As a roule of thomb, cosmetics are biodegradable, so you can consider a biological system.

The nature of cosmetics production results in a highly variable effluent quality, so you will need a huge equalization tank with proper aeration to avoid smell.

Oils used in cosmetics are usually soluble, and in this case, the best thing is to consider a coagulation + flocullation system. Due to the nature of variable quality, you need to have a batch system for the coagulation + flocullation system. So, you need to have (2) systems: one working and the other one in stand-by.

I'm a fan of MBR technology and sucessfuly installed in a Brazilian cosmetic company in Brazil and it has been working since 1997!! Nowadays, there are many membrane manufacturers.

Foam is a problem if there's production of shampoos and soaps. By using MBR process you can control the sludge age, which has an anti-foam effect and can be spread over the equalization / biological tanks.

So, don't worry about the level of organic load. Be worried about the variability of chemical composition of effluent stream.

If you would like to discuss more about it, get in touch with me by e-mail contato@yamaguchiengenharia.com.br.

Good luck!
