he nitrogen recovery system is designed to remove nitrogen from wastewater and store it in a product recovery tank for further processing to dried form. The system consists of a series of membrane modules that operate in the presence of acid to separate nitrogen from water. The acid is recirculated through an acid-active tank to capture the separated nitrogen. A concentrated acid tank provides fresh acid when acid in circulation has been exhausted. The wastewater is fed from a feed tank and undergoes pH correction by lime or sodium hydroxide dosing systems before entering the membrane feed system. The product recovery system collects the nitrogen-rich stream from the membrane modules and transfers it to a product recovery tank. The acid refill system replenishes the acid in the concentrated acid tank when the pH changes to a set point. Process description: Nitrogen Nutrient Recovery The nitrogen nutrient recovery process is designed to recover ammonia from the wastewater using membrane separation technology. The system configuration is provided in Table 1, Plant Configuration. The wastewater is fed to the wastewater feed tank (P2-TNK01) via inlet flow control valve P2-HV02 through a direct connection from the wastewater pumping network or the bottom of the wastewater buffer tank from the client premises.
