Abstract
A method for reducing the odors of an anaerobically digested dewatered biosolids or other biosolids or sludge may include separating first anaerobically digested dewatered biosolids into first and second portions, storing second anaerobically digested dewatered biosolids, removing a portion of the second biosolids, and mixing the removed second biosolids portion with the first portion of the first biosolids. The method may be implemented in a system including a separation device, first, second and third transporters, a storage area, and a mixer. The separation device may separate the first biosolids into first and second portions. The first transporter may transport the first portion to the mixer. The second transporter may transport the second portion to the storage area. The second portion may be stored in the storage area for a select time period. The third transporter may transport a portion of the stored first biosolids to the mixer for blending.
