Faydalı Bilgiler

Parshall Flume (water) : A device used to measure the flow in an open channel. The flume narrows to a throat of fixed dimensions and then expands again. The rate of flow can be calculated by measuring the difference in head (pressure) before and at the throat of the flume.
Nitrification Stage (water) : A stage of decomposition that occurs in biological treatment processes when aerobic bacteria, using dissolved oxygen, change nitrogen compounds (ammonia and organic nitrogen) into oxidized nitrogen (usually nitrate). The second­stage BOD is sometimes referred to as the "nitrification stage" (first­stage BOD is called the "carbonaceous stage").
