WebQuestion: 6 ml of wastewater is diluted to 300 ml in a standard BOD bottle. Initial DO in the bottle was determined to be 8.5 mg/L. DO after 5 days at 200 C is found to be 5 mg/L. Determine BOD5 of wastewater and compute the ultimate BOD. Webreduction in BOD5 can be noted during simple settling. 2. Little, if any, of this BOD5 reduction could be attributed to the removal of "soluble" BOD5, as noted when comparing values for the "as received" and "settled" samples when filtered through a 0.45-um filter. 3.
