I would like to share that we are facing some issues in waste water in the term of the third-party test. Let me explain the process background, we are producing bread and vegetable processes.
In the last 6 months found wastewater parameters out of specification like COD and BOD.
For internally correction action has been taken as below.
1- Clean the all pits and remove the mud from the bottom of pits
2- check all chemicals; used dosages as per std (chemical just hand wash, detergent for utensils washing and vegetable washing phosphoric acid and chlorine used in 10-15 ppm in water)
3- clean the all drain pipelines with fresh water from the pits.
After that, we still found results that were out of specification. as attached please advise.
COD Std 150 result 958 ppm
BOD Std 80 result 512 ppm
Looking for your kind support.
