A study was conducted to determine the effects of solid‐liquid separation of liquid swine manure on ammonia
emissions from lagoons. It was found that although water quality changes were modest in the treated lagoon with respect to the control, total annual NH3 emissions abatement in the lagoon with solid‐liquid separation was 73% with respect to the anaerobic lagoon control. These results overall demonstrate that solid‐liquid separation technologies can substantially reduce ammonia emissions from anaerobic swine lagoons.
