In the CHEMPAC sewage treatment plants the water is constantly flowing through the rigid PVC matrix to which the biological film is attached.   As the water flows past the biological film, the bacteria on the film absorb organic chemicals as well as oxygen, nitrogen, phosphorous, and other trace nutrients required for their growth.

As the bacteria grow on the matrix and as more chemicals are added to the CHEMPAC units, the stationary biological film  will continue to build in thickness.  As the film becomes thicker, the depth of penetration by diffusion of the absorbed materials, such as oxygen or other nutrients, is insufficient to reach the entire distance through the slime to the plastic media.  At some point, the film will become sufficiently thick and the portion of the film closest to the plastic media will not receive any food or nutrient, particularly oxygen.

The inner layer of film becomes  anaerobic and the organisms lose their ability to adhere to the media surface.  The shear forces of the water and / or air bubbles flowing through the matrix will ultimately become great enough to tear this portion of the biological film loose from the media.  This process is called sloughing.  The solids which slough from the media will flow out of the CHEMPAC sewage treatment plants with the effluents and will be removed from the water through clarification in a settling module.  The exposed portion of the media surface will repeat the process of slime accumulation and sloughing.

In actual operation of the CHEMPAC sewage treatment plants units, biological film will be in a state of dynamic continuous growth and sloughing.  At any given time, portions of the media are always at some point between forming a new film and sloughing.

CHEMPAC sewage treatment plants represents the “State of the Art” technology in the field of waste water treatment. CHEMPAC sewage treatment plants combines the established diffused aeration principle with the reliability of fixed film system. CHEMPAC sewage treatment plants is a single tank package of outstanding performance and efficiency.

CHEMPAC sewage treatment plants is available in a range of standard modular sizes. It has wide ranging application in organic waste treatment. It is ideally suited for resorts, hotels and condominiums.

CHEMPAC sewage treatment plants is simple in  design and highly flexible in operation. The unique arrangement of fixed media results in unbeatable size to population treatment ratio.
