Experimental validation of a single-OUR method for wastewater RBCOD characterisation.

摘要: Wastewater characterisation is of primary importance for the correct design and management a treatment plant. The aim this work was evaluation new rapid easy to use respirometric technique readily biodegradable COD (RBCOD). When necessary calibration curve obtained, RBCOD assessment procedure needs less than 30 minutes. On contrary, conventional techniques require some hours. first step consists in calculating order point out correlation between oxygen consumed known amount added Sodium Acetate. To well aerated biomass (in remove residual substrate) Acetate related OUR measured. (DDO) (as Acetate). Therefore, concentration wastewater samples can be obtained according following steps: (1) measure ΔDO; (2) multiply ΔDO by Volume mixed liquor used test; (3) from curve, calculate equivalent Acetate; (4) estimate multiplying sample volume tested reactor. Some advantages are described paper.
