COD ranges between 1,50,000 mg/l to 3,45,000 mg/l in food waste. The value of COD varies for different food wastes.

Hi you can view this post:

https://www.researchgate.net/post/What_is_the_COD_range_for_any_wastewater_to_be_suitable_for_anaerobic_digestion

As stated above, there is wide variation in the COD value dependent on the composition of the food waste in question.  This will vary between sectors of the food chain e.g. food processing will be different to catering and within some sectors e.g. quick-service restaurants vs. bistros.

See http://kchbi.chtf.stuba.sk/cevoze/doc/pod9/poster/text/Food%20Waste%20as%20Biodegradable%20Substrates%20for%20Biogas%20Production.pdf as a typical example.

Putrescible food wastes from the consumer and food service sectors will tend to have a high moisture content (75+%) and be composed of about 50% fruit, vegetable and salad.

The amount of moisture in the waste depends on several factors including: the income of the population which in turn depends on the composition of the waste. In countries or areas with higher income, there is greater presence of materials such as plastics, cardboard or cans while in countries or areas with lower income mainly dominate the organic waste where the moisture content is higher. The COD will depend on the quantity of carbon, nitrogen and hidrogen present in the waste, while more content of carbon need to be oxidize, greater the amount of oxygen required to oxidize an organic compound to convert in carbon dioxide.

In this table you can see the content of carbohidrates in different food.

Thank you so much guys,you helped me too much,

Dear Pedro;I wish tha table which you gave me was in English.

Dear Mam,

150000 to 510000 mg/dm3

go through attached link.

Sir there is no link attached kindly send the source @dr.ananddevgupta

@murali k Sir need the source for COD value mentioned by you
