How do you size wastewater treatment plants?

Answer 1

Sage treatment whether primary , secondary or tertiary is usually dependant on residence time in the various stages of the treatment (settling, biotreatment, chlorination etc.) This makes the capacity of the plant equivalent to the ration of the normal maximum throughput , its concentration of contaminants and the retention capacity needed in the longest (or slowest) treatment stage.Som parts of the process such as chlorination or MLSS return can be sped up but not by much.

Answer 2

it all depends on what you're treating and the population it needs to accomodate..
