Valmetal US Farm Systems – Wastewater Processing Equipment

Innovation & Service for More Than 35 Years

Company Description:

Valmetal US Farm Systems is a pioneer in dairy waste water and manure handling equipment, with a complete system exceeding the most demanding waste handling needs. With systems designed and manufactured for dairy cows, hog facilities, fish hatcheries, food waste processing, irrigation, and digesters, Valmetal US Farm Systems is an international company with diverse experience to meet their customers’ needs.

Technology Description:

A Valmetal US Farm Systems separation system reduces water usage, odors, and produces separated solids that can be repurposed as bedding for cows or compost for fertilizer. Heavy duty pumps and agitators send well-mixed solids over sets of curved sloped screen separators. The separated solids moisture content is reduced by a screw press, dewatering conveyor, or roller press and then stacked for processing. The effluent from the screen separators can be further separated prior to being reused for irrigation or flushing.

  • Produces fiber for bedding, soil amendment and compost
  • Used extensively on dairies across the country to reduce concerns associated with storage and application
  • Do not significantly reduce nutrients from the manure stream
  • Can utilize many types of technology like slope screen, screw press, rotary drum and others

Newtrient Comments/Opinions:

Valmetal US Farm Systems has a long track record of manufacturing reliable gravity based solid-liquid separation equipment.   The company, originally known as US Farm Systems, was founded and operated by Rejean Houle and his family until October of 2018 when it was sold to the Valmetal Group, based in Quebec, Canada. The same proven systems and services are now provided by Valmetal US Farm Systems.
