The 300 Series Peat Moss Biofilter was designed based on the research conducted by Dr. Joan Brooks at the University of Maine during the 1980's and 1990's.
Throughout her professional career, Dr. Joan Brooks dedicated herself to study the use of sphagnum peat moss as a wastewater treatment media. In addition, Dr. Brooks researched the influence of fungus on the process of wastewater treatment. In her paper Pollution Abatement with Peat Onsite Wastewater Treatment Systems, Dr. Brooks concludes: "On adverse sites, where the use of conventional subsurface soil adsorption systems does not provide acceptable levels of treatment, sphagnum peat moss may be used as an economical method of onsite wastewater treatment. The peat system, when properly designed and constructed, is relatively simple to install, requires minimal energy and maintenance, and provides a high quality effluent without additional disinfection".
Disinfection capabilities may be the most beneficial aspect in using sphagnum peat moss as a wastewater treatment media. Throughout her research Dr. Brooks has identified dozens of species of fungi existing in sphagnum peat moss. Most notably recurring was the recovery of the penicillium fungus. Penicillium is the pre-cursor of the penicillin anti-biotic.
Throughout her research career utilizing sphagnum peat moss as a treatment media, Dr. Brooks consistently documented BOD5 reductions of > 90%, Total Suspended Solids reductions of > 85% and Fecal Coliform bacteria reductions of > 99%.
