A MOF (micro-organisms filter system) is a constructed active regeneration environment for many micro-organisms to co-exist and naturally reduce pollutants to manageable levels.

The system consists of a variety of constructed filters and flows where pollutant in suspension in water is broken down into basic safe elements.
The filters used are organic or mineral or flora or a mixture of all three dependant upon the pollutant type, topographical and geographic location. Most MOFS require little or no maintenance after establishment and will function throughout the year for many years dealing with the identified pollutant.
The initial seeding of the system with activated bacteria usually EM, effective micro-organisms, is an important part of the future success of the system. Consequently the fermented brew of active bacteria, EM, is best done on site to a planned timetable.

A MOF is a natural green engineering form of a traditional sewage farm without the chemicals and concrete, and designed to meet the local conditions in all aspects. The EM bacteria used in a MOF are totally safe to handle and use and come into contact with because they are all natural and organic.
The fundamental purpose of the EM, effective micro-organisms, is to stimulate rhizome and root hair growth to provide a natural habitat for the bacteria to live and feed from and establish a beneficial long term co-existence with the host plant. The food of the bacteria is our pollutant and the more colonies of bacteria present the greater the efficiency and natural regeneration.

The costs of a MOF compared to other commercial offerings are about one third.Until recently a reed bed was considered to be what we now call a MOF, however a reed bed is only a part of the proceess and is usually included in the system.
Most MOF's are warmed at certain times of the year with solar heating of some sort, this increases the number of process days available.
