Just like an ecosystem needs oxygen to sustain life, the same goes with treating wastewater. By introducing oxygen in the water, it aerates the water and kills off harmful microorganisms. When a reduction in biochemical or biological oxidation occurs, several issues can develop. Read today’s blog post about how Innova MB tackle your biggest wastewater challenges – head-on. The result is the most efficient wastewater treatment available at reduced costs.

Why BOD Matters in Biological Oxidation

First, let’s talk about why having a low effluent BOD is an indicator of good quality water. BOD – (Biological Oxygen Demand) is the amount of dissolved oxygen needed by aerobic biological organisms to break down organic material present in a given water sample at a certain temperature over a specific time period. You can gauge the effectiveness of wastewater treatment plants by monitoring effluent BOD levels.

Nitrates and phosphates in a body of water contribute to high BOD levels in receiving water bodies, since they are plant nutrients that can cause plant life and algae to grow quickly; when the algae eventually die off, aerobic decomposition depletes the oxygen in the water body, potentially killing aquatic life. It can also cause clogged filter aerators, which reduces process efficiency, and causes an increase in mechanical stress that results in less-than-desirable wastewater output.

Conversely, low BOD levels can inhibit nutrient removal. To get an accurate reading, BOD is measured for five days. Why? Because the first five days demand is more related to the Carbonaceous BOD, thus accounting for around 70% of the total BOD value. 

Biological Oxidation, Meet Innova MB

Biological oxidation is the mechanism where microorganisms degrade organic matter contaminants of wastewater. They feed on the organic matter in the presence of oxygen and nutrients. It reduces the BOD of wastewater, including the toxicity of impurities, which are converted to:


  • Carbon Dioxide
  • Water
  • Biosolids


Biochemical Oxidation removes organic pollutants useful as a food supply for the treatment ecosystem. Promoting this mechanism is therefore beneficial for wastewater treatment. Sludge is generated by this process as microbes grow, multiply, and are removed from the system via wasting (WAS) Phosphorus is removed biologically by cycling the water from an anaerobic zone to an aerobic zone under highly controlled conditions to force a Polyphosphate accumulating organisms (PAOs) to uptake excess amounts of phosphorus than they need, thus driving a net removal of phosphorus from the system.

This is where Innova MB products shine. Our line of specialized and proprietary micronutrients and cultured microbiology tackles all these biological processes, encouraging optimal wastewater treatment. With proven performance, we use a comprehensive approach to wastewater problems that increase floc formation and settling characteristics while decreasing COD/BOD levels. Innova MB-400 significantly promotes the biological oxidation of your wastewater—resulting in reduced processing times, less equipment wear and tear, and fewer surface water cleanings and maintenance.

Innova MB products vastly improve your plant’s performance by reducing sludge yields and decreasing your consumption/demand for on dewatering polymers, flocculants, and other costly chemistry.
