The difference observed in removal efficiencies during the dry and wet period for biochemical oxygen demand
(BOD) and chemical oxygen demand (COD) may be attributed to hydrological changes in the wetland .
After one year, the biochemical oxygen demand
in the mulch treatments were not different from the bare soil control.
TMP-related effluent improvements include a 63 percent reduction in Biochemical Oxygen Demand
, 84 percent reduction in Total Suspended Solids and a 90 percent reduction in Chemical Oxygen Demand.
Two methods based on the oxygen uptake measurement--the biochemical oxygen demand
and the short-term oxygen uptake measurements were used.
For example, in the case of bonds issued to provide industrial sewage facilities, the taxpayer must be able to prove that the subject wastewater meets the biochemical oxygen demand
limits set forth in the Treasury Regulations.
Among the rivers in which Tama-chan has been spotted since this summer, the Katabira River had the best water quality, recording the lowest biochemical oxygen demand
Biochemical oxygen demand
(BOD) biosensors have been developed to measure BOD faster than by the conventional method ([BOD.
The most significant results came from the fecal coliform test, the turbidity test and the biochemical oxygen demand
Other data collected included: water temperature, depth, air temperature, secchi disk, dissolved oxygen, fecal coliform, pH, biochemical oxygen demand
(BOD), bird survey, invertebrates, vegetation and soil.
A significant problem was the high biochemical oxygen demand
(BOD) caused by chemicals in the wastewater.
Children are packing pH meters, turbidity tubes, magnifying glasses, biochemical oxygen demand
bottles, nets and scoops, and heading down to the river, keen to learn how the real scientists do their stuff.
The organisms remove biochemical oxygen demand
(BOD), which is organic matter that consumes oxygen in a body of water.
