RCM's mission is to provide the best digester for
your dairy farm.  The appropriate digester for your dairy
farm depends on the climate and manure collection.

Flush collected dairy manure is best digested in a covered
lagoon digester.  If special solids concentrating equipment is
used, or flush water is extremely low, a complete mix
digester can be used.
Scrape collected manure is best digested in either plug flow digester or complete mix digester. A
plug flow digester require undiluted dairy manure.  A complete mix digester can handle manure
plus parlor water.

Manure mixed with sand presents a special engineering problem that RCM will review with the
farm.
