Question

The total Nitrogen load = (soluble organic nitrogen and ammonia from incoming wastewater) + (nitrogen from Return Activated Sludge) + (nitrogen from recirculation).

(a) True

(b) False

This question was posed to me in exam.

Question is from Nitrogen Removal During Wastewater Treatment topic in division Bacterial Metabolism in Wastewater Treatment Systems of Environmental Biotechnology

Answer 1

Right choice is (a) True

To explain: The total Nitrogen load in the sludge process is the summation of the organic nitrogen and ammonia contributed by the incoming wastewater, nitrogen from by the return Activated Sludge and nitrogen from any recirculation nitrification stages during the treatment process.
