BM respirometers are based on an open system, without oxygen and time limitations. Those conditions permit an unlimited number of possibilities and applications. Here we are listing some of the most common applications:

Optimization and energy saving
Energy saving is one important target in a WWTP maintenance and control. For that, BM Respirometry can determine the actual oxygen needs in the process and the minimum oxygen levels at which the process can efficiently operate.
Pulse of the process
Early very fast process assessment and early alert to anticipate potential problems that could occur in the near future.
COD fractioning
On that application, the software automatically calculates the total biodegradable COD (bCOD), readily biodegradable COD (rbCOD), and from here we can calculate the slowly biodegradable COD (sbCOD) and inert COD (iCOD). From COD fractioning we can analyze the actual biodegradable condition of the organic matter and the amount of non-degradable COD (inert) or refractory COD included in the effluent.
Substrate utilization rate
From bCOD and rbCOD respirograms we calculate the actual rate at which the COD is actually being eliminated in the activated sludge process. Form those data we can calculate the actual COD elimination capacity of the process within its current conditions and also the optimal, minimum and maximum loading rate and sludge age at which the process can operate.
Specific toxicity to a determined activated sludge
On screening (extremely fast) or precise modes, we determine the presence and toxicity degree of a determined wastewater in the activated sludge within actual conditions, and also experimenting different conditions and flow.
Advanced oxidation processes tracking
The combination of COD fractioning, substrate utilization rate and specific inhibition/toxicity permits the perfect tracking of any advanced oxidation system and assess the evolution of the substrate biodegration character throughout the treatment.
Biological Activity
To regularly follow the biological activity with the purpose to detect early signs of operational problems, to prevent the possible toxicity presence and bulking & foaming formation as well.
Bioaugmentation
Through regular monitoring of the specific respiration rates of an standard substrate, we can follow up the bioaugmentation effects along the time and determine the correct bio-product utilization and dosage.
Nitrification capacity
By means easy respirometric tests, we determine the capacity of ammonium removal of the process in its actual nitrification conditions and other possible conditions that the process may operate.
Effect of Dissolved Oxygen, Temperature and pH in the Nitrification process
The BM-Advance is specially designed to study the effect of physic-chemical conditions that could affect the nitrification process and to calculate the the minimum and optimal level for it.
Denitrification
From the consumed oxygen in the rbCOD value, we know the amount of carbonaceous matter necessary for the denitrification process. Furthermore, by means the ration of this consumed oxygen with the amount of nitrate to denitrify we calculate the denitrification capacity related with the available carbonaceous matter.
Operative parameters optimization (F/M, SRT, ...)
From COD fractioning, ammonium capacity and activity, we can control and calculate the operative parameters for an optimal process performance.
Nutrients ratio
Also, from rbCOD value we determine the correct carbonaceous amount to be taken into account in the C/N/P ratio and carry out studies related with nutrients deficiency.
Modelling
By combining different types of respirometric test, we can calculate the different stoichiometric and kinetic parameters; and also to give an important support to any of the simulation software that are in the market.
Activated sludge acclimatization follow-up
The BM respirometry can run an essential paper in a process set-up, at the time to be adapted to a specific wastewater or industrial stream by means of regularly tracking the biological activity and substrate elimination capacity.
Innovative processes studies
Ozonization, Hidrogen peroxide, Free radicals, Photo-Fenton Electro-magnetism, Electrolysis,…
Pilot plants
Design, management, research,…
R & D studies
In the BM respirometry we can find a wide fan of possibilities to be applied to R & D.
MBBR process
Thanks to a specially designed reactor for biomass-carriers (bed bio-films), the BM respirometers can be applied to MBBR process and run the same applications as normal activated sludge process.
