An Experimental Method for Evaluating Ammonia Emission Rates of Bio-Curtain
نویسندگان
چکیده
Bio-curtain (i.e., curtain) is a permeable cover equipped with spraying system for ammonia (NH3) control in swine facility. Previous studies investigated the NH3 reduction effects primarily based on concentration units. It challenging to determine actual efficiency because of large amount air discharged through surface curtain, and external wind rapidly dilutes disperses exhausted air. Therefore, this study investigates technique evaluate effect curtain terms emission rate. We constructed metallic single hole around gather it. The was calculated by comparing rate that monitored barn exhaust fan at during non-spray spray treatments inside maximum minimum operating barn’s fan. rates declined both operation fan, but higher conditions than non-spray. Accumulating NH3-absorbed water under low ventilation caused these circumstances.
