Abstract
A sequencing batch waste treatment facility with pretreatment mixing and equalization by mixing with selectively bred bacteria to achieve a selected waste to bacteria ratio, wherein waste is treated and reduced to acceptable biological oxygen demand levels for municipal-type waste treatment or general discharge per regulatory permit. A treatment colony of mature bacteria is cultivated and maintained in a treatment tank while a colony of young bacteria, separate from the treatment colony, is selectively bred in a bacteria tank to be particularly adapted to digest the waste being treated. Newly received waste is mixed to break macroscopic solid waste apart, into microscopic solid waste and to blend solid waste and liquid waste components into a waste slurry. Some of the selectively bred bacteria are portioned and mixed into the waste slurry up to an equalization point. The equalized batch of waste slurry is subsequently transferred to treatment.
