Water and Air
Movement of nutrients in excess amounts from manure and other byproducts to water and air can cause significant environmental problems. These nutrient losses to the environment can occur at the production site, during storage and during and after field application 2.
Ammonia emissions appear to have the greatest potential for adverse environmental and health impacts, while generation and transport of malodorous compounds provoke the greatest public concern 2.
ATD’s Manure Management System captures 100% of the solids in a drier form and virtually 100% of the dissolved nutrients daily. Nutrients are not lost to the environment by long term storage. Greenhouse gases from manure are eliminated by daily treatment.
Surface water that supplies municipal systems or is used for crop irrigation can be indirectly polluted by runoff. Water-borne transmission of Cryptosporidium parvum is a concern because the parasite can remain viable for months in natural waters and is resistant to many disinfectants 1.
ATD’s Manure Management System replaces lagoons and liquid manure application to crops, both of which are cited as a possible source of pollutant leaching to surface and ground water. The ATD system produces a moist solid capable of being stored above ground and applied whenever fields are accessible, thus dramatically reducing the risk of runoff and leaching. The dissolved nutrients have been concentrated approximately 10 times thus reducing volume to ease pin point application as dictated by the Nutrient Management Plan. Our Water Cleanup process produces usable water year-round. Biological treatment does not attempt this standard and often relies on allowing nitrogen to escape in the form of free nitrogen, ammonia or nitrous oxide.
Nitrogen and phosphorus from manure and other sources have been associated with algal blooms and accelerated eutrophication of lakes and streams 2.
ATD’s Manure Management System does not allow water and nutrients to escape to lakes or streams thus eliminating algal and eutrophication threats.
