We've switched from glycerin as a food supplement for wastewater bugs to natural BOD by adjustments to our primary settling basins. TTHMs in our effluent have spiked to over 100ppb and are regulated for aquifer recharge and direct potable reuse. Could it be that natural BOD has much more TTHM...
Formula that I've seen is Flow x BOD/ Volume UNDER AERATION x Volatile Suspended Solids. A colleague says its actually total volume of all basins including anoxic. Which is right?
