Method for treatment of agricultural waste

A method for treating a liquid containing waste manure, the method comprising:

• a. providing a treatment apparatus comprising at least a first vessel, and a filtration system in liquid communication with the first vessel, the filtration system comprising a first active filter including a first housing, a first displaceable filter medium, and a first displacement actuator disposed between the first housing and the first displaceable filter medium;
• b. delivering a portion of the liquid containing waste manure to the first vessel;
• c. adding a first reagent to the portion of liquid containing waste manure to cause the formation of waste manure flocs of a first size;
• d. adding a second reagent to the portion of liquid containing waste manure to cause growth of the waste manure flocs of the first size into separable waste manure flocs;
• e. separating the portion of liquid containing separable waste manure flocs within the filtration system into a waste manure sludge and a first filtrate;
• f. dewatering the waste manure sludge by actuating said first displacement actuator to displace said first displaceable filter medium and producing a dewatered waste manure solid cake and a second filtrate;
• and
• q. composting the dewatered waste manure solid cake within the active filter by causing air to flow through the solid cake.

• and
• g. adding an amendment material to the portion of liquid containing separable waste manure flocs prior to separating the portion of liquid containing separable waste manure flocs within the filtration system into the waste manure sludge and the first filtrate, wherein the amendment material increases the porosity of the dewatered waste manure solid.
