This is one of many companies that sell the mixed bed ion exchange resins and kits so you can do it yourself at home.

Making the resins require a quite sophisticated organic lab and lots of energy to make and then to "reclaim" after use unless they are just dumped. The resin looks like light sand before use and dark sand after use. You really must have a mixed bed of 3 types, anionic, cationic and organic to properly remove everything you need to remove.

A proper unit can use sewer water as input and turn out potable water at the other end. If the organic removing resin is not used, then the organics (and odors) go through.

Do what works for you.
