Prof. Jesús Fernández González (http://www.upm.es/observatorio/vi/index.jsp?pageac=investigador.jsp&idInvestigador=6432) and I are exploring with phytobiodepuration technologies from pig slurry directly to obtain premium fertilizers that can be sold and reduce the depreciation periof for the investment required. Do you have an average data of the pollutants value from the wastewater you obtain after biogas processing?

yes. I have the data 

anoxic -> biological trickling filter -> biological lagon, with following technologycal parameters: water flow 0.2 m/h, residence time in anoxic tank ~ 4h, in biological pond ~ 10 days, cross section of biological trickling filter tank 1m2. With the parameters input to the water as follows: TSS = 1228 mg/l; COD = 195mg/l BOD = 534 mg/l; N-NH4 = 405 mg/l; Ntotal =518 mg/l and Ptotal =67 mg/l,the water quality after the treatment process exhibit the respective parameters 108; 252; 116; 118; 185 and 22; performance efflciencifs are TSS ~90%o; COD ~ 80%; BOD ~ 78%; N-NH/ ~ 71%; ƩN ~ 64% and ƩP
