Abstract

Currently, the use of PPCP products has increased significantly. Personal Pharmaceutical Care Products (PPCPs) enter the environment through human activities such as residue from hospital and community use. This study will discuss the stability of the intermittent and continuous reactor^s performance in removing COD and ammonium from domestic waste, which has been operational for 20 days, and an increase in the concentration of pharmaceutical residue pollutants every five days. The sediment used was derived from the septic tank sediment and used artificial waste with an initial COD of 100 mg / l and initial ammonium of 80 mg / l. The results showed that the increase in the concentration of pharmaceutical residual pollutants in the operational reactor affected COD removal and ammonium efficiency. The stability of the reactor performance in removing COD and Ammonium in domestic waste contaminated with pharmaceutical residues was disrupted because microorganisms in removing COD and ammonium were disrupted amoxicillin concentration increases.
