Animal waste management system and method thereof

An animal waste management system for handling a waste slurry having a plurality of coarse solids contained therein flushed from an animal confinement housing at a flush rate, comprising:

• separation means for separating the coarse solids from the waste slurry flushed from the animal confinement housing;
• removal means for removing a volume of the waste slurry produced from the separation means to produce a remaining volume of waste slurry;
• conditioning means for conditioning the remaining volume of waste slurry from the removal means to maintain air quality in the animal confinement housing;
• and
• recycling means for recycling the conditioned waste slurry through the waste management system at a recycle rate, whereby the removed volume of waste slurry has a high concentration of solids;
• wherein the recycling means comprises a recycle pump, and the conditioning means comprises a controller in communication with the recycle pump, the controller being adapted to stop operation of the recycle pump when the level of remaining waste slurry within the conditioning means reaches a predetermined level, whereby failure of the recycle pump is prevented.

• removal means for removing a volume of the waste slurry produced from the separation means to produce a remaining volume of waste slurry;
• conditioning means for conditioning the remaining volume of waste slurry from the removal means to maintain air quality in the animal confinement housing;
• and
• recycling means for recycling the conditioned waste slurry through the waste management system at a recycle rate, whereby the removed volume of waste slurry has a high concentration of solids;
• wherein the amount of solids in the removed waste slurry is in the range of approximately four to eight percent.

A method for managing a waste produced from an animal confinement housing, with a waste management system comprising:

• flushing the waste from the animal confinement housing with a flushing material at a flush rate to produce a waste slurry having a plurality of coarse solids contained therein;
• separating the coarse solids from the waste slurry to produce a coarse solids-free waste slurry;
• removing a volume of coarse solids-free waste slurry to produce a remaining volume of waste slurry;
• conditioning the remaining volume of waste slurry portion to maintain air quality in the animal confinement house;
• and
• continuously recycling the conditioned waste slurry through the waste management system at a recycle rate whereby the removed volume of waste slurry has a high concentration of solid;
• wherein the recycle rate is at least approximately ninety-five percent of the flush rate.

• and
• continuously recycling the conditioned waste slurry through the waste management system at a recycle rate whereby the removed volume of waste slurry has a high concentration of solids;
• wherein the waste management system comprises conditioning means, and wherein the step of recycling comprises the steps of:
• pumping the conditioned waste slurry with a recycle pump;
• and
• controlling the recycle pump such that operation of the recycle pump is stopped when the level of the remaining volume of waste slurry in the conditioning means reaches a predetermine level.
