Sand-Manure Separators (SMS)

Sand-Manure Separators (SMS) produce a clean, recyclable product that can be used for bedding dairy cows, as well as producing a nearly sand-free manure effluent. An SMS is most often placed in a Sand Separation System for dairy producers who want to avoid the challenges traditionally associated with handling sand and manure.McLanahan Sand Manure Separators convey, wash and separate materials by utilizing a screw shaft at an inclined angle. As material is conveyed toward the discharge end, the liquid manure begins to separate from the sand. Utilizing this method, producers are able to capture 80 to 90 percent of sand depending on sand size and water quality. Higher recovery is possible when used with a Hydrocyclone.

No full-time operator is required to turn sand-laden manure into clean, recycled sand with the SMS. Using a Sand-Manure Separator also eliminates the need for producers to enter pits or confined spaces to access settled sand. It reduces, or even eliminates, exposure to harmful manure gases.

McLanahan Sand-Manure Separators can be operated in conjunction with anaerobic digester systems without substantial difficulties. Anaerobic digestion systems require very high sand removal and any sand bypass can become problematic. McLanahan has been successfully operating SMS Systems with anaerobic digesters for years.
