Observe: Hydrochloric acid or other acid that contains chlorine should not be used to neutralize the sample since chlorine interferes the results of wastewater BOD.
The time period "seed" refers to microorganisms that consume the biodegradable natural and organic matter in samples for measurement of BOD. Domestic wastewater (influent and effluent) from Organic water therapy plants (before disinfection), provide the top supply of seed and give the most reproducible final results. Other resources, including industrial wastewater, may not have plenty of microorganisms or could comprise toxins that avoid the organisms from increasing. If wastewater is just not offered, put together a seed Alternative from the freeze-dried capsule like PolySeed ®.
