9 hours to recover from the loading and return to the BOD5
level prior to dumping.
In terms of BOD5
and COD, their variation indicates that concentrations associated are significantly superior to the thresholds established by the norms WHO, these values vary between 47 and 50 mg /l for [BOD.
a,b) Different superscript in the row of BOD5
and T-N effluent concentration indicates statistical differences among R1 to R4.
Management pattern in the employment of organic fertilizer associated with feed greatly impacted water quality, especially with regard to nitrogen, phosphorus, TSS, organic and inorganic solids, COD, BOD5
and conductivity, with direct effects in the lake (P5) and with medium impact on phosphorus and nitrogen rates.
Both systems tested achieved COD and BOD5
removal efficiencies ~60 and 99%, respectively, which are similar to values reported for this kind of systems (Pokhrel and Viraraghavan, 2004) and for aerobic moving bed bioreactors (Villamar et al.
The determination of BOD5
was carried out as prescribed in literature using the aired modification method (18).
Results of COD and BOD5

com)-- Why design the performance of an incubator for rapid, and thus energy-intensive, heating up and cooling down phases, when it is used mainly for storing BOD5
samples, drinks containers or cosmetics at constant temperatures over long periods?
The PC-BOD/Titrate Duo enables labs to prepare and analyze samples for BOD5
and then, with a change of the rack and probe holder, analyze different samples for pH, conductivity, alkalinity and turbidity.
Results show that ammonia, total phosphorus, BOD5
, phosphorus and organic matter in the sediment removals in the CW were higher and indicated that macrophytes had an important role in removing these variables.
Many wastewater treatment plants use BOD5
levels to gauge the amount of waste that is present in water and the more BOD5
, the more treatment wastewater requires.
The strength of the incoming organic matter in the sewage was extremely low at 15 to 40 mg/L BOD5
or biochemical oxidation demand.
