Is it possible to remove phosphorus from sewage from 19 mg/l to 1 mg/l by biological means?
How? Which biological treatment do you suggest?
Hello a question as complex worth thinking about.
Talk about biological treatment - does absolutely nothing to say is completely abstract.
There is no biological treatment - pour the simple reason that there is no treatment. You must add the mode or type of treatment as for example: treatment of purification.
Bathroom and it is the misfortune of our time. The term - organic - means everything and say nothing, it is only a word that looks good on a text.
Everything must be biological - to pay may be a biological purification plants --. FR rated XXIX effluent that must be pure of chemicals, and where all its features - biological - have been preserved, otherwise it is biochemical and the - biological - treatment cannot be done.Then perform a - biological treatment - to the tool and the place of purification.
The tool, the nature the gives us as a whole, but because of the configuration of our sewage system, the tool is extremely rare.
the place or container must also present - biological - features otherwise there is not treatment - biological-
In nature biology is not specific to one element among many others. It's a whole. However when infrastructure includes impurities on a particular area, concentrations of pollution are so important that they are dangerous because unusable from the point of view of their treatment.If an idea came to transgress the nature it destabilize the biological harmony and nature cannot respond, turns everything into toxic mud. It is what often happens with the current system.
Biology is able to take everything out unless he was given something exceptional natural.
One can only change the form or arrangement of Phosphorus in the molecules and unless precipitates are formed for separation and are filtered out , it can not be removed from water.

After having read and learned of so many wonderful techniques that make it possible to depollue the water that we use to improve our living conditions, the time has come to mobilize so that these means of depollution are applied so that no dirty water is Discharged into our rivers. It is also time to reward these innovators who do such beautiful things!

Yes, Of course it is possible and desirable too to avoid chemicals. Look at Nutrem. Juhani

Further to my initial post and provide you maybe with a summary overview of our system technology:
Description
Our system hosts a diverse and large population of organisms capable of the degradation of aromatic and aliphatic hydrocarbons, chlorinated solvents and pesticides. The degraders become conditioned in the matrix which has a much slower decay rate than the pollutants that pass through. Furthermore sparingly soluble compounds such as large PAHs and PCBs are also effectively degraded. This is because the voids within the system are ideal habitats for a microbial ecosystem capable of utilising a diverse range of organic substrates. The niches within the matrix also have a range of REDOX potentials meaning that anaerobic and aerobic habitats exist side by side. Most significantly, the technology not only sorbs and retains these organic molecules but it is able to completely mineralise them rendering the end products of carbon dioxide and water

By dosing ferric chloride it can help. Firstly you need to determine Alkalinity and if Alkalinity is 20mg/l meaning the dosing rate of ferric it will be 20mg/ls

I think that Duckweed (Lemnoideae) floating on a slow moving flow is good in it.

Yes phosphorous can be removed from sewage. We deal with Genetically Modified Bacteria. Along with this and our MAST Technology wastewater treatment where we use Microalgae it is possible to attain the target effluent values that you wish to attain.
In case you wish to get more information you can reach me at advenvtech@gmail.com. I am based at Mumbai and we will be shortly starting a 12 mld wastewater facility in one of the western states of India.

Good Afternoon,
We have technology that can remove the phosphorous and recover the phosphate.
Where are you located?
I would suggest eqs for Europe at 2 mg/l is more easily achievable and meets legal threshold.

To recommend a biological or non-biological approach, I would need more information on he influent makeup. BNR of phosphate requires short-chain organic acids in the anaerobic step and is also sensitive to the presence of nitrate/nitrite. Often with high influent phosphate, you are best served by using combined biological and tertiary chemical treatment.

Bonjour
Il est impossible d'effectuer un traitement -biologique- sur des effluents chimiques. c'est une hérésie.
Pour faire du traitement il faut déjà définir quel genre de traitement comme par exemple un traitement d'épuration. Hors tous les systèmes actuels n'ont aucune vocation d'épurer, il s'agit simplement d'une gestion des excréments. Pour preuve la production mondiale de résidus de boue d'excréments en sorti des STEP est de plus de 45 millions de tonnes. ou est l'épuration?
Si on ne peut pas faire -du biologique- avec des effluents chimiques, il faut aussi expliquer en quoi consite le sans oxygène. L'eau est composée de H2O. Là ou il y a de l'eau il y a de l'O2. A quel momment et par quelle action un effluent aérobie devient-ils sans oxygène. Ou se situe la barrière entree l'aérobie et la sans oxygène?
Hello
It is impossible to perform a - biological - treatment on chemical effluent. It is a heresy.
Do the processing to already define what kind of treatment as for example a purification treatment. Off all current systems have no vocation to purify, it is simply management of feces. For evidence world production of residues of mud of excrement out of the STEP is over 45 million tonnes. or is the treatment?
Can't do - organic - chemical effluent, with should also explain what consists the without oxygen. Water is composed of H2O. Where there is water there is O2. At what moment and by what action an aerobic effluent becomes - they without oxygen. Where is located the entry barrier aerobics and without oxygen?
Yes....BardenpHo, AO, AO2 etc....or just use a non-propiatary anaerobic zone at head of aeration as described in WEF Nutrient control manual or MOP 8
