Ammonia & Nitrogen

Ours is a complete wastewater treatment system. Effects of high levels of nitrogen can be reduced, such as DO depletion, fish poisoning, and harmful algae growth. Common examples of nitrogen entering wastewater are urea or urine, food wastes, chemicals in detergents, and other agents coming from industrial structures.


When these are flushed and mixed into the sewage system, urea, for example, will be immediately hydrolyzed into ammonia. The gaseous form of ammonia in water is converted into ionized ammonia or ammonium.

BAJA SUSTAINABLE WATER uses microbes to treat wastewater instead of chemicals. These microbes can treat ammonia aerobically. We use different sets of denitrifying and nitrifying bacteria to break down ammonia. We break down ammonia into nitrites and nitrates by using our denitrifying bacteria while a different set of nitrifying bacteria breaks it further down to elemental Nitrogen which dissipates to the atmosphere through our ‘Biobed’ development. The Biobed formed is a layer of microbes that will form at the bottom of the wastewater tanks that contain 20 to 100 billion microbes per cc.


Since our microbes are facultative, we are able to strip the oxygen from the nitrates thus releasing Nitrogen to the air when we hit the anaerobic zones.

How do we attack Ammonia?

Here are the steps in which our microbes attack Ammonia:

1. A microbe attaches to the Ammonia (NH3) and turns into Ammonium (NH4).

2. Another microbe then attaches to the Ammonium, breaking it down into Nitrites (NO2).

3. The Nitrites continue to break down, turning into Nitrates (NO3).

4. These Nitrates are heavy and sink below the Bio-Bed that has formed at the bottom of the tank or pond from the multiplication and movement of our microbial mix.

5. This creates an anoxic space.

6. Within this anoxic space, another microbe will ‘rip’ the Oxygen (O2) from the Nitrates, effectively releasing Nitrogen Gas and Carbon Dioxide into the water column.

7. Due to constant mixing, there will not be floating scum. No odor will be present.
