“…The amount of oxygen consumed by these microorganisms in decomposing organic matter in a body of wastewater is referred to as biochemical oxygen demand (BOD) (Hogan, 2010; Tchnobanoglous and Burton, 2001). Chemical oxygen demand (COD) measures the amount of oxygen required for complete oxidation of the organic matter in the wastewater to carbon (IV) oxide and water (Uwidia and Ademoroti 2011;Sawyer et al, 2003). COD and BOD5 tests are used by Rustum et al (2008) to measure oxidation of wastes and oxygen consumed by microorganism.…”

The functional relationship between BOD5 and COD was evaluated using domestic sewage samples collected from a sewage treatment plant in an estate in Warri, Delta State, Nigeria. Two types of samples were collected: raw domestic sewage,(influent) and biologically treated domestic sewage (effluent).The correlation coefficient r between the BOD5 and COD was determined and values were 0.99 and 0.94, respectively for different sewage samples. The regression analysis carried out showed very strong correlation . The linear correlation established was: COD = 1.62 BOD5 + 15.82 ; r2 = 0.978; COD = 1.58BOD5 + 9.21; r2 = 0.878. Results obtained above were also judged as significant at 95% and 99% confidence levels. Confidence intervals obtained were: 1.53£ a £1.71 at 95% and 1.49£ a £1.75 at 99% for the raw sewage; 1.37£ a £ 1.80 at 95% and 1.27£ a £1.90 at 99% for the biologically treated sewage.

The research was aimed to recirculate the treated wastewater from Whiteleg shrimp farms in following each other without interruption by using concrete gutters containing ACM (Assembled Constructed Materials) check dams as the filters. Among the 2-inch diameter of chipped-assembled-constructed materials, the ACM-Brick filter was the most effective rather than roof-tile, blocked cement, and rock, respectively. Three ACM-Brick check dams with 5-m space between them were indicated as 47.3% treatment efficiency together with flow rates of 600 to 900 L/hr, and up to more 65% and 85% for fourth and fifth ACM-Brick check dams while the first and second dams found 13.0% to 28.4% efficiencies. Seemingly, irrespective of employing brick, roof-tile, blocked cement, or rock for constructing the ACM check dam was installed in concrete gutters with the size of 1-m width, 0.5-m depth, and more or less 20-m length that could be served needs in recirculation aquaculture of Whiteleg shrimps to gain satisfied benefits. Culturing Whiteleg shrimps in 3-sq.m. and 3-cu.m.concrete gutters containing only one of 0.5-sq.m. and 1-depth ACM-Brick filters by RCB design for 4 treatments (culturing shrimp densities) and 3 replications found the density of 105 juveniles/3m 2 (6,606 kg/ha) with the most harvested-added weight 2,710 kg/ha (69.55 % of beginning weight), and decreasing after increasing the density of 6,720, 8,371, and 11,382 kg/ha in corresponding to harvested-added weight 65.29%, 46.36%, and 42.33%, respectively. The findings also informed that flow rate of 720 L/hr indicated somewhat high effective influences on decreasing of water temperature, salinity, pH, DO, EC, alkalinity, TDS, BOD, NH 4 -N, NO 2 -N, and NO 3 -N which were conditioned for recirculation aquaculture of Whiteleg shrimps.
