DODA - Screw Press Separators
Top Quality – Great Reliability – High Durability

Company Description:

In the 1950s young Aldo Doda created the first ever vertical chopper pump from an old, beat up harvest machine to help handle slurry on his family dairy farm in Italy. When neighbors saw its success, they wanted him to build one for them as well, and so did many others. In the 1960’s Aldo created the AFI – horizontal chopper pumps – to mount on slurry tankers. Around the 1970’s Doda brand was beginning to be known in the United States as a slurry pump. Mixers, separators & other complementary items became a natural follow up to the basic chopper pumps

  • Can utilize many types of technology like slope screen, screw press, rotary drum and others
  • Used before many other technologies to remove coarse solids
  • Minimal maintenance and operator time required
  • Proven technology for nitrogen recovery, phosphorous recovery, storage reduction, GHG reduction, and odor control but with limited impact in all cases

Newtrient Comments/Opinions:

Coarse solids separation technologies:

  • Produces fiber for bedding, soil amendment and compost
  • Used extensively on dairies across the country to reduce storage and application concerns

DODA has been selling solids separation technology in the U.S. since 1960 and in 2007 established an independent U.S. corporation located in St. James, MN. They have installations on over 100 dairies in the U.S. ranging in size from 60 to 5,000 cows. DODA was very cooperative in providing information to Newtrient in order to refine their cost and performance information.
