BOD/TSS % Removal
BOD and TSS are both slightly low in the percentage of removal as we discharged through the month of April. This is expected to be due to pond turnover with the changing temperatures that we received multiple times going back and forth from warm to cold, and we will continue to monitor this to ensure these trends don’t continue as we continue to discharge this year. We will also monitor for I&I as this may contribute to a cleaner initial influent flow providing less potential for treatment.
