On demand water research about 30% of surface water treatment plants currently use chloramines and the percentage of surface water treatment plants using. Biological oxygen demand measures the amount of oxygen used by microorganisms in the oxidation of organic matter when there are too many phosphates in aquatic systems, algae proliferates, dies, and then aerobic bacteria decomposes them, starving the water of oxygen and killing bacteria and other aerobic creatures. Biochemical oxygen demand (bod, also called biological oxygen demand) is the amount of dissolved oxygen needed (ie demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.
