Shakeel Shah, HelloYour ...

Shakeel Shah, Hello Your presentation is a summary of the whole problem of all countries of the world. In Dakar or the temperature is higher than the one you describe there is the same problem. I think you made a very big mistake by using the word processing -biologique- when all along your benefit you only speak technicality. A -biologique- treatment is carried out by a -biologique- element that is found in a sewage effluent biologic-which is not the case of sewerage effluents. They are -biochimique- and it can be no treatment - biologically. How do you prove what I say? Simply by producing mud. Sanitation -biologique- produces no mud, it eliminates all organic mass and mainly feces excrement. As these are -biologique- it promotes the elimination of other organic body masses. The treatment of sewage treatment plants, as you demonstrate so well in your presentation focuses on filtration and think even add to improve treatment. Any technical action deteriorates the characteristic -biologique- effluents. Conclusion: You can not perform a biological treatment in the conditions you listed. My first concern by developing organic cleansing that was the temperature. So the bacterial -biologique- job runs every degree of temperature, it just slows down in low temperature and increases in high temperature. So that is called -biodégradation- work can be done so you have to extend the transit time of the effluent treatment system at low temperature period and accelerate high temperature. Which of course is impossible to do on a sewage conditioned by the flow of wastewater to be treated. In high temperatures is the problem of putrefaction. An organic material in a liquid under a large temperature by quickly decaying and will methanised thoroughly. From experience the increase in temperature with a biological effluent causes two obligations: - That the medium is aerobic state as a whole and to all the places where they will find this is not the case in a wastewater treatment plant - The transit time is accelerated. I was able to conduct tests on a forced air adding micro-station. After a month analysis showed a slight decrease in processing performance. forced air destroys the characteristic - biologically in the oxidant. By a lucky chance I could confirm this by finding a solution to -biologique- following traces the treatment performance -biologique-. In domestic sewage from the sewerage is dumped every day thousands of liters of cleaning products containing hazardous chemicals microphones. We must add all sanitizers and disinfectants for medical and para medical, destroying all the feature - biologically effluent. When added to the supply air is caused by a reaction chain of these chemical particles which further oxidize the medium. The first rule to maintain a state -biologique- effluent is to eliminate the addition of chemicals. Of course, impossible to do in the collective principle. By implanting against the concept of a metropolitan CEBRE is possible to improve the conditions and slightly increase the purification performance of a wastewater treatment plant which is zero, close to zero from the perspective -biologique- .
