- Is there a connection between BOD and cod in dairy wastewater?
- In wastewaters from other dairy plants, it usually do es not exceed 0.1 g/ L (18). and COD values varying from 0.1 to 100 g/ L (3,11,27,39). It is known that with dairy wastewaters there is a direct r elationship between BOD and COD values, as expressed in Eq. 2. such a lo gical connection cannot be made.
- Why are the BOD 5 values of dairy wastewater misleading?
- The BOD 5 values of dairy wastewaters are often misleading since the normal seeding materials used for BOD 5 estimation are nonspecific bacteria that cannot biodegrade some of the nitrogenous compounds present in the effluent.
- What does BOD 5 / cod ratio mean?
- BOD 5 /COD ratio above 0.4 indicates high biodegradability of the wastes. All reported dairy industries make use of biological processes to treat wastewater. Dairy wastewater treatment require improvements to meet the discharge standards. Dairy industries in Minas Gerais use treated wastewater in fertigation.
- Why is BOD analysis of dairy wastewater problematic?
- The BOD analysis of dairy wastewater is problematic for many reasons; these include the heterogeneity of the samples at different times and nonspecific microorganism's present in general seeding material.
