Dear Kristaps,
Wastewater treatment - Biological treatment. Secondary treatment is the biological treatment of water using a wide variety of microorganisms, primarily bacteria. These microorganisms convert biodegradable organic matter contained in wastewater into simple substances and additional biomass.
Aerobic wastewater treatment processes include treatments such as activated sludge, oxidation ditches, trickling filter, lagoon-based treatments, and aerobic digestion. Equipment may include diffused aeration systems or mechanical surface aerators, such as RWL Water’s Tornado aspirating aerators, in order to maximize oxygen transfer and minimize odors as the wastewater is treated.
Anaerobic digestion is a process in which microorganisms break down biodegradable material in the absence of oxygen. It can be used to process a wide range of organic material, from food waste and grass to waste paper and animal waste digestion is used for effluent treatment in food and beverage manufacturing, as well as for treatment of municipal wastewater, chemical effluent, and agricultural waste.

Hello Prem
This is literature. He need to prove results. A very important element missing from this description: biology. How can you make with an effluent totally chemical - biological - treatment? How can we make - biological treatment - when the majority of micro organisms are dead? How can we make - biological - treatment without describing the kind of treatment as for example: treatment of purification? How can we make - biological - treatment in a short space of time too? How can we explain the production of over 45 million tonnes of residue of mud at the output of the STEP? How to explain biochemical effluent with oxygen, so - aerobic - have a space, an area that would create without oxygen? How to explain by what process an - aerobic - effluent becomes spontaneously without oxygen when it is brewed by a mechanical arm that adds air to the depths of the pool? How to explain the process by which organisms micro - aerobic - become spontaneously without oxygen? How to explain the presence of legacy organizations - aerobic-biological - pickups can survive in a chemical effluent?
We're simply in the Court of miracles, utopias.
Bonjour Prem
Tout ceci est de la litérature. Il faut pour le prouver donner des résultats. Un élément très important manque à cette description: la biologie. Comment peut-on faire du traitement -biologique- avec un effluent totalement chimique? Comment peut-on faire du traitement -biologique- quand la majorité des micros organismes sont morts? Comment peut-on faire du traitement -biologique- sans décrire le genre de traitement comme par exemple: traitement d'épuration? Comment peut-on faire du traitement -biologique- dans un espace de temps aussi court? Comment peut-on expliquer la production de plus de 45 millions de tonnes de résidus de boue en sortie des STEP? Comment expliquer un effluent biochimique contenant de l'oxygène, donc -aérobie- avoir un espace, une zone qui se créerait sans oxygène? Comment expliquer par quel processus un effluent -aérobie- devient spontanément sans oxygène quand il est brassé par un bras mécanique qui fait rentrer de l'air jusqu'au plus profond du bassin? Comment expliquer le processus par lequel des micros organismes -aérobie- deviennent spontanément sans oxygène? Comment expliquer la présence de micros organismes d'origine -aérobie- -biologique- puissent survivre dans un effluent chimique?
On est tout simplement dans la cour des miracles, des utopies.
