Plenty of well proven anaerobic methods are in existence to leisurely convert cattle farm waste into useful derivatives such as manure. But, unfortunately, anoxic processes are hectic and quite hard to comply with. Thus, the present study aimed to primarily address highend solutions to overcome the technical drawbacks of the existing anaerobic methods. Nutrients from the cattle farm waste streams were recovered by aerobic treatment mechanism, utilizing fluidized bed reactor (FBR) with dairy and goat manures as feed influents. In order to optimize the recovery, an effective pH value was determined and upheld by using a buffer solution of MgCl2.6H2O and NaOH. The maximum amount of struvites recovered from goat wastes was 93.2% of magnesium, 70.2% of ammonia, and 92.2% of phosphate. While the witnessed recovered fractions were scanty in the case of dairy wastes, which were as follows: 92.2% of magnesium, 68.2% of ammonia, and 91.2% of phosphate. The influence of pH and HRT on the yield of nutrient recovery has played a significant role. The study revealed supplementary recovery was achieved at the optimum condition (i.e., pH 9.0, HRT 2h) when the influent stream was doused with 0.06 M Mg2+. Ultimately, it was concluded that goat manure has a higher capacity of removing the nutrients compared to the dairy manure.
