Facilities with seasonal flows such as wineries, vegetable processing, or vacation resorts often have period of low flows at light loadings followed by a rapid increase in both waste volume and concentration. This situation is rarely discussed in textbooks, but is surprisingly common. The challenge is combining equilization, buffering capacity, bioaugmentation, and polymer addition to meet treatment requirements. By fully considering the options before the season flow starts, operators can manage the event with fewer problems.
Here is how I evaluate the various options:
