Waste effluent treatment system and process

A system for treatment of agricultural animal waste comprising:

• means for separating the animal waste into a first solid component and a first liquid component;
• means for separating the first liquid component into a first fine solid component and a second liquid component having an organic loading of 0.00253 lb/ft3 of lagoon volume/day×K to 0.0105 lb/ft3 of lagoon volume/day×K, where K varies from about 0.4 to about 1.2;
• means for digesting organic material in the second liquid component and separating fine solids in the second liquid component into a third liquid component;
• and
• means for distributing the third liquid component to at least one of:
• an animal confinement facility;
• the environment;
• and, at least one of:
• crops and fields.

A system for treatment of agricultural animal waste comprising:

• a solids separator;
• a primary settling basin receiving liquid from the solids separator;
• a secondary settling basin receiving liquid from the primary settling basin;
• a first facultative lagoon receiving liquid from the secondary settling basin;
• a second facultative lagoon receiving liquid from the first facultative lagoon;
• and
• a liquid transfer system transferring liquid from the second facultative lagoon to at least one of:
• an animal containment facility;
• the environment;
• and at least one of:
• crops and fields.

A system for treatment of agricultural animal waste comprising:

• a settling lagoon receiving the animal waste;
• a facultative lagoon receiving liquid from the settling lagoon;
• and
• a storage lagoon receiving liquid from the facultative lagoon.

A method for treatment of agricultural animal waste comprising the steps of:

• providing a source of animal waste, the animal waste including solids and liquids;
• separating solids from the animal waste;
• digesting organic material from the animal waste after the step of separating solids from the animal waste, while further separating fine solids from the animal waste, producing treated liquid, the organic material having an organic loading of 0.00253 lb/ft3 of lagoon volume/day×K to 0.0105 lb/ft3 of lagoon volume/day×K, where K varies from about 0.4 to about 1.2;
• and
• after the step of digesting organic material, at least one of:
• recycling the treated liquid to an animal containment facility;
• discharging the treated liquid to the environment;
• and, applying the treated liquid to at least one of:
• crops and fields.

A method for treatment of agricultural animal waste comprising the steps of:

• collecting animal waste, the animal waste including solids and liquids;
• temporarily storing the collected animal waste;
• separating at least a portion of the solids from the collected animal waste;
• storing the separated solids for a first predetermined period of time;
• after the step of separating at least a portion of the solids from the collected animal waste, directing the collected animal waste to a primary settling basin;
• directing any liquid from the stored separated solids to the primary settling basin;
• holding the collected animal waste in the primary settling basin for a second predetermined period of time;
• directing liquid from the primary settling basin to a secondary settling basin;
• holding the liquid in the secondary settling basin for a third predetermined period of time;
• directing liquid from the secondary settling basin to a first treatment lagoon;
• holding the liquid in the first treatment lagoon for a fourth predetermined period of time;
• directing liquid from the first treatment lagoon to a second treatment lagoon;
• holding the liquid in the second treatment lagoon for a fifth predetermined period of time;
• and
• at least one of:
• recycling liquid from the second treatment lagoon to an animal containment facility;
• discharging liquid from the second treatment lagoon to the environment;
• and, applying liquid from the second treatment lagoon to at least one of:
• crops and fields.
