The purification parameters before and after the treatment are pH, 5 day biochemical oxygen demand, chemical oxygen demand, total suspended solids, total nitrogen and total phosphorus.
Presumably, the suspended particulate matter contributes to the increase in biochemical oxygen demand (Kelly, 1992).
The tests were Biochemical Oxygen Demand [BOD] and Total Suspended Solids [TSS] analysis.
Farm officials called in the Environment Agency for help and tests found alarming Biochemical Oxygen Demand levels of water pollution.
The state permit limits the biochemical oxygen demand (BOD) to 30 mg/L, 30 mg/L total suspended solids (TSS), 1.5 mg/L phosphorous, and 3.3 mg/L ammonia.
[ILLUSTRATION OMITTED] The new ordinance includes these changes to limits: Parameter (in mg/l) DWSD Previous Proposed Final Limit Change Limit Fats, Oils and Grease 2,000 750 1,500 Total Suspended Solids 10,000 2,290 7,500 Biochemical Oxygen Demand 10,000 1,200 7,500 Phosphorus 500 16 250 Cadmium 2.0 0.12 1.0
It is also used to lower refining energy, biochemical oxygen demand, and overall paper manufacturing costs.
We evaluated the potential for the ground wood wastes to impact oxygen demand by measuring biochemical oxygen demand in the runoff: There was no difference in biochemical oxygen demand between the dimensional lumber control and the treatments containing engineered wood products, but all the mulch treatments had a higher average biochemical oxygen demand than 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.
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 (BOD).
