Working To Make A Cleaner Environment

National-Wastewater-Systems-Inc-logo 5-stage-system

The Solar Aerobic sewage treatment system is an extended aeration activated sludge process. This type of treatment depends primarily on the use of air that is introduced into the wastewater from your home as soon as it enters the treatment unit. When air is introduced, it promotes the growth of organisms that break down the organic solids. The introduction of air into wastewater is called aeration. Aeration provides dissolved oxygen that mixes with the wastewater promoting and sustaining the organisms or bacteria that breakdown the organic solids that enter the treatment plant.


The pretreatment tank, the first component of the system, begins the anaerobic decomposition of the influent and retains any non biodegradable materials entering the system with the wastewater. The aeration chamber introduces oxygen into the wastewater by means of a very quiet, highly efficient linear air pump. This aeration process mixes the organic materials contained in the wastewater with the bacterial population allowing the bacteria to attack and break down the organic materials.


In the clarifier, the solids separate from the liquid and settle to the bottom. That matter is called activated sludge which is returned to the aeration chamber to be remixed. As solids settle in the clarifier, a clear, odorless effluent rises and flows out of the wastewater treatment plant through the chosen method of disposal.

1. Pretreatment tank where influent enters the home.

2. Aeration chamber where oxygen is pumped into the sewage.

3. Clarifier where clear odorless effluent rises.

4. The extremely quiet, efficient aerator and pump.

5. Complete control center monitors and controls the system.
