Anoxic tank ....aeration k pehle aata h ????

[@ETPKnowledgeJunction]

Yes, Anoxic tank ko aeration tank se pehle isliye lagaya jata hai taaki denitrification process ho sake, jisme wastewater mein present nitrates (NO3-) ko nitrogen gas (N2) mein convert kiya jata hai. Anoxic environment mein, jahan oxygen absent hoti hai, bacteria nitrates ko energy source ke roop mein use karke nitrogen gas banate hain, jisse nitrates water se remove ho jate hain. Aeration tank mein oxygen present hoti hai, jahan yeh process nahi ho sakti. Isliye anoxic tank pehle lagaya jata hai taaki nitrogen removal efficiently ho sake aeration stage se pehle.
