Great beginning but no clear end!

[@amna4853]

I'm wondering why you are not using a magnetic stirrer and just place the rod inside the beaker? thanks!

[@adrianacuna682]

What is blank bod value?

[@spurthichadharam9144]

Thank you, I think BOD non test can or shall be done every 3 days BOD = 1/ ( Initial DO + Final D.O * DIL FACT )

[@Ilemaurice687]

hello what 5 requirements that must be compiled with in order to obtain reliable BOD data?

[@petermagro7371]

Why isnt there any seeding material and a glutamic acid standard introduced into the method ? They must think there is no COD in this water ! Slack method !!

Let's be honest - The BOD blank will always deplete more than 0.2 mg/l
