Thanks so much for your discussion enthusiasm. I can't answer for each your comments
I am so sorry cause provided information is not enough.
I have added more. please open the attachment file
I need your help follow:
1 . primary treatment: some tips for method to reduce COD content
2. Biotechnology: I will use 4 main stages include: remove Oil and grease - DAF tank - UASB tank - MBBR tank. But I am encountering some problem in calculation for UASB and MBBR.
I need more document to refer: choose inlet parameter as, formula etc
( if someone have designed this kind of wastewater, please discuss deeply in formula)
Well.First of all what is BOD/COD ratio then we go for further treatment method and caluclation.It is permissible up to 4 times.We have check is it required caustic or oxydation treatment,Biological etc.I think your influent water is Jet fuel,brine of petro chemicals.
This sounds like a trick question - a COD of 300 000 mg/l must be almost pure blood or waste from an abattoir or tannery? Reduce the pH by adding acid and put it into an anaerobic digester. 19 m3/day is not too much - you could consider an evaporation pond, but it is likely to cause very unpleasant odours. Please let us know what the waste is.
It is an interesting project, but we will need more information.
Please describe the process that genereates this wastewater and post a lab analysis including the BOD5, BOD20 and all the parameters that could help to find solution.
With these levels and mixture of pollutants, especially COD and fats, oil... best way tor treat wastewater is an evapoxidation system: no problem with those pollutants, with basic pH, with high conductivity levels you obviously have, salts, metals...
Calculations to design a treatment plant depend on many factors such as:
1. Source of wastewater domestic or Industrial, as you mention acid oils, caustic soda it looks Industrial source. If it is so then defining type of industry is highly essential.
2. Influent & Treated Effluent Characteristics means what you are uploading in the plant & what you would like to achieve e.g. Secondary quality of effluent with BOD & TSS 30 mg/L or Tertiary quality i.e. both 10 mg/L level.
3. Level of contamination in influent in terms of BOD, TSS, Oil/grease, Total Nitrogen, Total Phosphorus, Dissolved sulfide, odor emission etc.
Therefore give us more details to help you in appropriate manner.
In addition to what Mamtaji told, we also need info on the end use for which the treated effluent is put to such as for agrixultuag, horticulture or for any induatey and the type industry to decide on the extent of treatment like secondary or tertiary etc.
You will need to provide more information on TDS, BOD of the waste (as well as metals) and what parameters you hope to achieve at the conclusion of treatment. The final parameters will dictate what steps you need to include and in what order.

Have you calculated the analysis of the expected wastewater and do you know what result you want and what you want to do with it after it has been treated?
When do you think the plant will need the wastewater treated?
With this info we can tell you if our equipement can do what you want, and when you have a sample of the wastewater, after we have anaysed it we will calabrate the equipment.
