type flow of waste water treatment

Question

Hello, I'm a new user of OpenLCA. I'm currently analyzing data related to electricity usage in wastewater treatment using OpenLCA 2.5.0 with the Ecoinvent 3.3 database. To create flows related to the wastewater treatment process, which flows should I use? Elementary flows, product flows, or waste flows?

Answer 1

you will probably need all type of flows:

- wastewater that is treated in the plant: waste flow;

- emissions (e.g. CO2 from microrganisms): elementary flow;

- other product inputs (electricity, chemicals e.g.): product flow.

Good luck!
