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 System captures virtually 100% of the solids in a drier form and nearly 100% of the dissolved nutrients in a concentrated form, daily. Nutrients are not lost to the environment by long term storage. Most GHG’s are eliminated by prompt separation.
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 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 Treatment 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 System does not allow water and nutrients to escape to lakes or streams thus eliminating algal and eutrophication threats.
