dwaste

An experiment was conducted to study the O2UP, oxygen uptake in milligrams of oxygen per minute, given five chemical measurements: biological oxygen demand (BOD), total Kjeldah nitrogen (TKN), total solids (TS), total vital solids (TVS), which is a component of TS, and chemical oxygen demand (COD), each measured in milligrams per liter (Moore, 1975).
