Bacterial treatments with ...
Published by Cleveland Jones, Member of the Geosciences Advisory Board at NXT Energy Solutions, Inc.,
Bacterial treatments with off-the-shelf biological consortium products are the answer. I have written on this topic, defending the use of biological products (bioaugmentation products) in WWTPs, as a standard practice, in order to achieve and maintain optimum performance of operations.
This may not be easy to do, since in many countries, including Brazil, there is strong resistance to using a biological product treatment regimen, often mistakenly viewed as a costly practice. Even sanitary authorities have reservations about the use of bioaugmentation products, and, naturally, chemical suppliers leverage this fact in order to plug their products, which are often less effective, have many undesirable side effects, and may be even more expensive.
Furthermore, many companies offering such solutions tend to be very unprofessional in their claims and explanations, as some responses herein demonstrate, with untenable claims. This notwithstanding, the more professional suppliers will be able to offer products that are more effective, and, in some cases, quite specific for certain WWTP applications.
It would be unfortunate if the poor practices of some less scrupulous suppliers resulted in discrediting effective solutions. In most cases, any WWTP will be able to improve efficiency or other parameters, including cost of operations, with a biological product that is well matched to the operating conditions. Such a constant treatment regimen will go a long ways in preventing upsets and Nocardia breakouts, and will allow occasional problems to be solved through temporary adjustments in dosage and operations (increased doses and changes in some operating parameters, for short periods).
The selection of a biological product should consider whether the supplier can offer adequate, prompt and effective technical support and problem solving.
Good luck!

Bonjour
Sur le fond vous avez totalement raison, mais dans la pratique même en adoptant votre raisonnement c'est impossible.
Il faut toujours garder à l'esprit ce qu'est la caractéristique -Biologique- de l'effluent.
Au tout départ de la production de l'effluent d'eaux usées dans l'habitat, entre le robinet et le siphon de l'évacuation la caractéristique est -biologique- en partant du principe que les utilisateurs.consommateurs de l'eau n'utilisent pas de produits léssiviels contenant des molécules chimiques.
Si cet effluent rejoint un effluent contaminé par le chimique, il perd sa caractéristique -biologique-
Dans un réseau d'assainissement collectif des milliards de litres de produits chimiques sont déversés dans le collecteur: eau de Javel, Destop, Déboucheur chimique, acide chlorydrique, désinfectant et aseptisant de toutes sortes provenant du Médical et du paramédical ainsique les solvants de peinture, platre et autre ciment.
On ne peut donc faire de l'épuration -biologique- qu'au niveau de la production d'eaux usées. C'est aussi responsabiliser les consommateurs sur l'idée du pollueur/payeur.
L'infastructure d'épuration individuelle est 1000 fois moins chère que le réseau collectif, totalement efficace à plus de 98% avec un procédé d'épuration -biologique-
Même si les utilisateurs de l'eau dans l'habitat sont respectueux de son usage, le dispositif de collecte et la STEP détruisent la caractéristique -biologique- des effluents
Dans le procédé "Fosse Biologique"lyseconcept sont activés entre 14/16 paramètres biologiques

Hello on the bottom you're totally right, but in practice even by your reasoning it is impossible.
Always keep in mind what is the feature--biological effluent.
At the very start of production of the effluent of sewage into habitat between the faucet and the siphon of the evacuation of the characteristic is - biological - on the premise that the utilisateurs.consommateurs water do not use product lessiviels containing chemical molecules.
If this effluent joined an effluent contaminated with the chemical, it loses its feature - biological-
In a collective sanitation of billions of liters of chemicals are dumped into the collector: bleach, Destop, chemical Unblocker, acid piece, disinfecting and sanitizing of all kinds from the Medical and the paramedical as well as the solvents in paint, plaster and other cement.
So can - biological - treatment at the level of the production of sewage. It is also empowering consumers on the idea of the polluter pays.
The infrastructure of individual purification is 1000 times cheaper than completely effective, collective network to more than 98% with a process of biological - treatment-
Even if the users of water in the habitat are respectful of its use, collection and the STEP destroy - biological - characteristic of the effluent
In the process "Fosse Biologique"lyseconcept are activated between 14/16 biological parameters
