Micro-organism ratio:

Determine the F/M ratio (in units of lbs BOD5/lb MLSS-day) using data provided in the above example problem.

Solution

By definition,

F/M = Q So/X V = [33.75 × 106 l/day × 310 mg/l)/[4,300 mgSS/l × 5,000,000 l] = 0.49 kg BOD5/kg MLSS-day

Various reactor configurations are available, each along with its own set of advantages and disadvantages. The two basic types are plug flow (PF) and completely mixed flow (CMF) reactors. PF reactors offer higher treatment efficiency than CMF reactors, other than are less able to handle spikes in the BOD load. Other changes of the procedure are based on the manner in that waste and oxygen are introduced to the system.
