Treatment of Pharmaceutical Wastewater by Rotating Biological Contractor

Rotating Biological Contactor is a type of attached growth biological waste water treatment unit mostly used in the waste water treatment units. In secondary stage of treatment process where we will use methods like trickling filters or activated sludge process but Rotating Biological Contactor provides 8 to 10 times higher level of treatment facility. Rotating Biological Contactor consists simple design, high reliability, and low energy consumption. It contains series of rotating discs to support the biological growth with help of sustainable organic matters, which consists of 5 parallel designed discs for their rotating process in waste water treatment unit. With arrangement of merging the 60% of wastage. Where 40% of circular portion of rotating discs may rotate with the respective rpm based values with constant flow of wastage. In the ecological system of life cycle every biotic and abiotic will discard the toxic elements disbursement in atmosphere. The absorb particles while circular rotating discs may absorb 60% of merged toxic elements with that the continues and intermittent rotation may cause huge impact in clearing of toxic elements in wastewater such that the organic and sustainable may cause zero impact to the surrounding environment to absorb particulate matters like nitrogen compounds, carbon compounds, sulphates, zinc, oxygen compounds and some of the heavy metals. Its efficiency depends on the hydraulic retention time, disc submerged in wastewater, disc rotating speed. It is mostly used for nitrification, denitrification, phosphorus removal process in waste water treatment.
