WebNormally, each primary clarification unit can be expected to remove 90 to 95% of settleable solids, 40 to 60% of the total suspended solids (TSS), and 25 to 35% of biochemical oxygen demand (BOD). As with other treatment plant unit processes, several control calculations may be helpful in evaluating the performance of the primary treatment process.
