When you are haven to deal with your local Health Officials, Engineers, and Septic System Designers. The following diagram is a conventioal subsurface wastewater infiltration system.

The treatment options include physical, chemical, and biological processes. The use of these options will be determined by your site's specific needs.
The right hand column of the following chart shows you many of the different approaches that can be taken, all depending on just what the objective is for your site.
