Enzyme treatments promote the growth of beneficial bacteria in your system. Natural bacteria generated by the solid waste partially decomposes the waste in the system and can reduce the amount of solid material by as much as sixty percent. However, the daily infusion of harsh chemicals and detergents into the system can cause the bacteria to become depleted. By introducing enzyme preparations into your drains at regular intervals, you promote the healthy growth of these organisms thereby cutting down on solids, considerably. The enzymes are also effective at reducing odors.
