It should be known that the principle says “activated sludge” does not exist. From the moment when a Biological element becomes - mud - it loses this biological characteristic. Your diagram describes Ci above shows it perfectly since those Ci pile up. In a circle closed in putrefaction there is no more oxygen. More oxygène=plus of vie=plus of micro alive oragnisms: it is a dead product. And more you will try to bring oxygen there by brewing it (activated sludge) and more it will oxidize. Two years of studies on these problems enabled us to define this theory. In more one essential concept does not appear at all in your talk: the biological aspect of the effluent. you seek a 'biological' solution with an element which lost this concept. Reassure it is the world case of the treatment of waste waters. The Biological cleansing solves all these problems even further while going since after the treatment the water rejection becomes productive because it is sent on a vegetalized discharge system http://www.lyseconcept.fr, http://www.creabpa.fr E-mail: lyseconcept@gmail.com for a personalized proposal
