I am a member of a team working on the NoBi (Bidirectional Nodes) program sponsored by Conacyt (National Council of Science and Technology) Mexico and by the NSF (National Science Foundation).
Our team is aiming to determine the needs and requirements regarding the treatment of wastewater with high organic load, generated in the production centers of food, meat, poultry, etc.
How can we know which treatment solution exactly to apply? How does the treatment change as the organic load changes?
I would strongly suggest cross flow membrane bioreactor for anaerobic conversion of waste waters with varying organic content and even high concentrations of particulate matter.
A unique feature in this process treatment is the retention of biomass combined with high loading capacity and COD removal for even complex waste waters with high particulate concentration
It is important to understand what the organic load exactly is. In this industry, you are dealing typically with fats, oil, grease, blood, bone etc. that needs to be separated and decomposed by bacteria.
A screening process will definitely be needed to reduce the bulk of the load.
If the size of the plant is an issue, fats and oils are typically flocculated and separated through dissolved air floatation (DAF). This is skimmed off using a mechanical skimmer. Alternatively, you could use an individual or series of anaerobic and aerobic ponds or tanks with mechanical aeration.
Tertiary treatment is either settling pond, clarifier, media filtration or micro/ultra filtration.
The footprint (size) of the ponds and tanks will increase with the higher organic load to allow sufficient residence time for the bacteria to convert and digest the organic matter. This is the main factor to consider when choosing a treatment process because it contributes to capital costs.
Mechanical aeration and physical barriers such as membranes can reduce the footprint of the plant considerably but will result in increased operating costs.
I am experienced in Agriculture and Food production wastewater treatment in Asia and Australia. My company also designs and manufactures a range of innovative technologies for this specific application. If you email me at andrew@waterandoilsolutions.com.au, I'll be happy to discuss possible solutions for your needs.
There is but one solution. It is called BIOREMEDIATION. There is only one species that has the genetic code of reducing all organic compounds into their elemental/nutritional form. It is Called ARCHAEA. The load density or type is irrelevant. Your only real decision is the potable water discharge. 1. back into the reservoir or 2. sell/give the nutrient dense potable water to the farmers. 3. dump it into rivers allowing the cleaning process to continue all the way to the ocean. The process has been working for a few billion years. Hard to compete with that work history.
La filtration ne doit pas être considérée comme un traitement. C'est uniquement une fonction séparative du solide et du liquide. Cette fonction n'apporte aucune efficacité à l'épuration qui elle élimine la polllution organique.
la vocation d'un filtre c'est de retenir, ce qui le fait colmater, la masse solide retenue se transforme en boue sous l'effet de la putréfaction.
Par une action on créé une autre problématique: Que faire des résidus provenant de la filtration? c'est simple ils terminent tous dans l'environnement par un moyen ou un autre
Hello filtration should not be considered a treatment. It is only a separate function of the solid and the liquid. This function does not give any efficacy to the purification which removes the organic polllution.
The purpose of a filter is to retain, which makes it clog, the solid mass retained turns into mud under the effect of decay.
By one action one creates another problem: what to do with the residues from the filtration? It's simple they all end up in the environment by one way or another
For effluents from such 'high organic loaded' industries, baleen alone dramatically reduces TSS/COD/FOG to less than 1,000mg/L (with screenings recovered as byproduct for added ROI) but when coupled with suitable-flocculation reduces these loadings to around 100mg/L (once again as value-added byproduct, and once again for added ROI).

Sergio, sometimes its not how much load but what kind of organic load? polyphenols, high ammonia, high fog, high sugar....all these have different characteristics that you have to watch out for.
Bonjour Bien vu cher ami mais il faut aller encore un peu plus loin car la surveillance n'apportera pas de solution d'épuration. On ne peut pas effecteur une épuration ciblée sur un élément dans un effluent comprenant de multiples composants, et encore plus grave quand il existe des composnats chimiques comme la plus part des effluents
Hello well seen dear friend but we have to go a little further because the monitoring will not bring a purification solution. Targeted purification cannot be performed on a specific element of an effluent comprising multiple components, see chemical components as the most part of the effluent
Bonjour Ce n'est pas tant la concentration de morue qui est importante que l'état de cette concentration. Si la morue est en décomposition, putréfaction, tous les systèmes actuels ne pourront rien produire d'autre que de la boue. Une matière organique en putréfaction est déjà de la boue .
Hello it is not so much the concentration of cod that is important as the state of this concentration. If the cod is decaying, rotting, all the current systems will not produce anything other than mud. A rotting organic matter is already mud.
As suggested by Bruno anaerobic digestion followed by aerobic treatment to remove residual COD and ammonia would be the best option. Depending on the requirements denitrification might also be necessary.
Bonjour En quoi consiste la digestion anaérobie? Par quel principe un effluent aérobie laisse t-il s'implanter un espace sans oxygène? comment se matérialise la barrière aérobie-anaérobie? Comment biologiquement parlant, un espace sans oxygène se créé en si peu de temps? l'eau est composé de H2O, que devient l'oxygène ?
l'anaérobie n'existe pas sur terre, l'anaérobie ne peut pas exister sur notre planète
Hello what is anaerobic digestion? By what principle does an aerobic effluent allow an oxygen-free space? How does the aerobic-anaerobic barrier materialize? How biologically speaking, a space without oxygen is created in such a short time? Water is composed of H2O, what becomes oxygen?
The anaerobic does not exist on Earth, the anaerobic cannot exist on our planet
Since 40 years we convert a broad range of biodegradable wastewaters with high organic load (COD, BOD) worldwide to green energy (methane > steam, electrical power, ...). When this COD is largely soluble (low TSS/COD) then we use high-rate methane reactors after adequate pretreatment (if/as needed), equalisation and conditioning. For wastewaters with medium to high TSS, we use upstream TSS removal, hydrolysis or larger medium reactors (mesophilic or thermophilic according to specific case).
Depending on the kind of wastewater and its COD concentration as well as on the discharge requirements a polishing conventional or advanced aerobic biological treatment may be needed.
If interested, I would be happy to send you more information via email.
une eau usée n'est pas biodégradable, seules le sont les matières organiques. L'eau n'est pas biodégradable et la pollution dissoute qu'elle contient n'est pas non plus biodégradable.
Faire une filtration de l'effluent en amont n'apporte pas de réelle solution puisque ces résidus se transforment en boue. La boue est un poison pour l'environnement
Hello a waste water is not biodegradable, only organic materials are. Water is not biodegradable and the dissolved pollution it contains is not biodegradable.
Filtration of the effluent upstream does not provide a real solution since these residues are transformed into mud. Mud is a poison to the environment

Anaerobic wastewater treatment is usually very suitable for wastewater from the food and beverages industry. Two examples of techniques are Biopaq ICX and Biopaq AFR. The last technique is also used in wastewater treatment from the poultry industry.
We deal in nano bubble solution, due to which we propose a DOF ( Dissolved ozone floatations much better and efficient than DAF). The ozone nanobubbles provide much better coagulation and flotation of suspended solids than conventional air and at the same time due to extremely high ozone dissolution ( upto 95% ) and creation of hydroxyl radicals ( our technology produces one of the maximum in this case.) ..we are able to achieve high levels of oxidation and flocolation and coagulation all in the same tank...In Korea and the Far East most of the pig farms / chick farms use this system now.... The result is extremely low footprint, allowing reuse of water, very low retention time,elimination or reduction of odour significantly in the first process itself,the biological reactor can decompose the remaining organic load more effectively due to less load and less complex chains to break, the use of ozone nanobubbles again in the tertiary treatment along with sand filters and carbon filters eliminates all pathogens ( up to 99 %) load to achieve reuse standards...This technology also can be used for extremely efficient surface cleaning and spraying of the ozone nanobubble water on the Caracass results in very low use of water plus better disinfection and shelf life... So over all this is the technology for the pig/ chicken and cattle industry... Not to mention the feeding of high DO water to the cattle and pigs also results in high yield and better immunity thus reduced mortality....

Engr. Mansoor Ahmed is correct. Generally, the food process wastewater is fully biodegradable and very easy to be treated, although its organic load is high. Normally the treatment process starts from an anaerobic digestion that can generate energy, rather than consumes energy. Depends on the effluent discharge requirement, you may require a further treatment. If the effluent quality of anaerobic digestion doesn’t meet the discharge target, then an activated sludge process (via aerobic treatment) will be required. If the effluent reuse is required, a MF-RO will be the final process.
Your question raises many questions that are addressed in the other answers. The information that you are sharing with us, suggests that you are dealing with a major program for your country. In effect, reinventing the wheel would be unfortunate. The disposal, treatment and valorization of waste streams that originate in slaughterhouses and meat processing centers is well documented. Different studies describe procedures for the identification and selection of Best Available Technologies for this industry. Anaerobic digestion is an interesting option to investigate.
The Scandinavian countries, for instance, have designed very efficient programs and processes.
