Changes in Biochemical Oxygen Demand
(BOD) of Samples.
Steckel says secondary treatment typically requires removal rates of 85/85, or 85 percent of the biochemical oxygen demand
and 85 percent of the solids.
Chemical oxygen demand (COD), five day biochemical oxygen demand
(BOD5), total nitrogen (TN) and total phosphorus (TP) were measured by Japanese Industrial Standard (JIS) standard analytical methods.
However, electrical conductivity and biochemical oxygen demand
, chlorophyll and pheophytin showed a particular pattern of variation, fitting a polynomial curve.
Total Suspended Solids (TSS) were extremely high, up to 934mg/l at Mill number 2 and 4, whereas Total Dissolved Solids (TDS) were high at Mill number 3 and 5, Biochemical Oxygen Demand
(BOD) levels at various mills were 85.
Currently the two companies are said to be pursuing over 100 potential opportunities where glycol management programmes are being created at airports to reduce the effect of biochemical oxygen demand
(BOD) in Europe's waterways.
The ANOVA (Table 1) showed that the organic matter variables, biochemical oxygen demand
(BOD), dissolved organic carbon (DOC), chlorophyll-a and thin sediment (TS) were different (p < 0.
The effectiveness of this bio-filter was measured by using biochemical oxygen demand
(BOD) and total suspended solids (TSS) analysis.
The Biochemical Oxygen Demand
(BOD) test is used to measure waste loads to treatment plants, determine plant efficiency (in terms of BOD removal), and control plant processes.
The SEPT accused the CEO Ismail H Zakaria and said the "inspection of the Al Noor Sugar Mills wastewater by SEPA found the levels of biochemical oxygen demand
(BOD), chemical oxygen demand (COD), total suspended solids (TSS), pH, and oil and grease in excess of the National Environmental Quality Standards (NEQS)".
