Pemilihan Nutrisi pada Kolam Aerasi Unit pengolahan Limbah Cair Menggunakan Perhitungan C, N dan P (Studi Kasus di PT.XXX)

Abstract

In accordance with ongoing development of PT. XXX, various problems in waste water management has been appeared. One of them is the selection of nutrient that is the most suitable for generated liquid waste. The previous research had analyzed the characterization and optimation of waste water treatment based on aeration system. This research was conducted to select the nutrients that were most suitable to decrease organic content. The optimum dose of nutrition is necessary to optimise process of organic content degradation. Research results showed that nutrient samples 2 with the dose 500 mg/L also urea and NPK as 107.99mg/L and 127.5 mg/L resulted in the highest value of COD decrease, namely 86.52 %. Nutrient samples 2 showed the highest TSS decrease namely 70.09 %
