Dear Kathryn,
There are lots of suggestions that can help you, but it will depend on the wastewater parameters, climate, temperature, disponible area and other ones.
Many of them can be integrated in a possible solution of your trouble, and now I will tell you some of the ones we can help.
1) Use the sewage system (pipes) as part of the treatment system: you can do it if you bioaugment the microbes in the system.
2) Use a USB (little compex), anaerobic filters (simple) or any other anaerobic technology that can initially remove organic contaminants and that can produce some biogas to you can use that biogas to generate energy for the same treatment system.
3) Dose or use the adequate microbial formulation for your treatment: You can treat the wastewater developing and using the native bacteria, but many times this bacterias doesn't have the high performance of the microbial formulation.
4) Install a bioreactor as a biocleaner that continuously produce the adequate bacteria and that partially digest the organic sludge in the same tank. This system continuously release big quantities of bacteria that help to digest more effectively the organic compound as some other nutrients if the system is correctly designed.
5) Use direct filtration wastewater: It is treatment concept that use a filtration technology (from 25 to 0,2 um), and that can reduce the contaminants and safe area and energy due to it remove many of the organics as solids.
If you have a healthy bacterial system in your biological treatment plant, you can digest your contaminants with less power compsumtion.
You can use this suggestions separately or you can integrate some of them in the same solution.
Let us know the daily flow, lab analysis, description of the actual plant and maybe with our technical partners we could help you.

Bonjour
Comment peut on augmenter d'un coté la présence bactérienne Aérobie, dans un effluent quand de l'autre coté on va créer un milieu sans oxygène: c'est contradictoire.
En plus il est important de déterminer comment par un principe actif on transforme un milieu Aérobie en milieu sans oxygène pérenne aussi vite. La nature est bien faite mais c'est aussi contradictoire quand on connait la vitesse de circulation de l'effluent dans l'infrastructure de getion des eaux usées.
Hello how can we increase on one side the presence aerobic bacterial, in an effluent when on the other side we will create an environment without oxygen: it is contradictory.
In addition it is important to determine how by an active principle an aerobic medium is transformed into a medium without perennial oxygen as fast. Nature is well done but it is also contradictory when we know the flow rate of the effluent in the wastewater getion infrastructure.

Hi lyseconcept,
Maybe initially it could sound contradictory,but I will try to answer your question in my best effort,
“How can we increase on one side the presence aerobic bacterial, in an effluent when on the other side we will create an environment without oxygen: it is contradictory?”
You can treat the wastewater in a first anaerobic step to produce the acid fermentation products, or even to reach the biogas yield, and at the second step you can treat the remaining organics in that wastewater in an aerobic system (if it is necessary) to reach the regulation law parameters required.
Thinking in that way, you could use the pipes as a kind of bioaugmented anaerobic system to reach the fermentation products and feed it to an anaerobic system obtaining the biogas to use as energy source. After that you can treat it in an aerobic system saving area and aeration energy costs.
Other example is that you use a direct filtration system at inlet separating the solids and sending them to a small anaerobic digester obtaining the biogas to use as energy source. The filtered wastewater with less organics contaminants can be send to the actual plant and treated using less aeration energy.
Other ideas are that they use other simple technologies as anaerobic covered lagoons, facultative lagoon wetlands that could use more area, or even some other more complex automated systems that have tiny equilibrium and must be operated by high skilled people or that will need remote control.

Orlando is quite right. The current system has to be studied before providing the most suitable solution.
