Interpretive Summary:

Technical Abstract: In a properly designed dual drain tank, solids laden effluent exists through the bottom of drain of the tank and the cleaner mid-column tank water exists the side drain. Connecting the bottom drain line to a primary solids capture device , such as a swirl separator, has a number of benefits. Primarily, heavier solids are removed from the tank immediately and removed from the system before they have a chance of breaking down and releasing extra metabolites into the system. Secondly, the removed solids puts less of a burden on secondary clarifiers or biofilters further downstream the treatment train. This article dprovides points to consider when implementing a dual drain culture tank design and how to incorporate a swirl separator into the design.
