You are absolutely right. But it is the dillution organic matter medium. This is the most difficult to obtain. You have to combine the concentrations of minerals to achieve the same ionic strength.
But what is the recommendation for the organic matter in the recipe you refer to? In most cases a simulation of wastewater treatment based on a synthetic medium without organic matter would not be realistic.
Hi Santosh, for synthetic waste water for diary or sago, I am not quite sure about this, but normally I use this recipe of preparing synthetic wastewater consisting of 666 mg/l CH3COONa, 125 mg/l NaHCO3, 44 mg/l KH2PO4, 160 NH4Cl, 25 mg/l MgSO4.7H2O and 1 g/l Bacto-yeast extract, 1 g/l Bacto-peptone, 1.25 ml/l of trace element solution, which contained (g/l): ethylene-diamine-tetra-acetic acid (EDTA) 15, ZnSO4.7H2O 0.43, CoCl2.6H2O 0.24, MnCl2.4H2O 0.99, CuSO4.5H2O 0.25, NaMoO4.2H2O 0.22, NiCl2.6H2O 0.19, NaSeO4.10H2O 0.21, H3BO4 0.014 and NaWO4.2H2O 0.050.
Can anyone suggest an article about the difference of synthetic wastewaters with unique or multiple carbon source? and the functions of yeast extract, peptone, sunflower oil? Thank you.
