Kuantitas Total Bakteri Coliform pada Instalasi Pengolahan Limbah Cair Medis Laboratorium Klinik

Abstract

Health service activities at the Clinical Laboratory produce infectious and non-infectious waste in the form of solid or liquid. Clinical laboratory liquid waste is one source of environmental pollution if the concentration exceeds the standard quality of wastewater. Polluted water quality parameters include microbiologics of Coli / Total Coliform Germs. Water quality with microbiological parameters can be used to determine the presence of bacteria, viruses, parasites. Bacteria used as indicators are Coliform bacteria. At present several clinical laboratories have implemented a Liquid Wastewater Treatment Plant. So that the waste discharged into the environment meets the standard quality standards for hospital liquid waste, and minimal pollution. This study aims to determine the quantity of Total Coliform at the inlet and outlet points of the Wastewater Treatment Plant Laboratory Medical Liquid. The results showed that the quantity of Total Coliform at the inlet sampling point of the liquid media waste at the Wastewater Treatment Plant Laboratory reached the highest value > 1.6 x 105 MPN / 100 ml, and after processing at the Wastewater Treatment Plant Laboratory decreased to 0 MPN / 100 ml (no coliform was found ), and with the highest value of 2.7 x 103 MPN / 100 ml, according to the waste water quality standard.

Car service station wastewater treatment using electrocoagulation technology

“…Coliform bacteria are non-sporic organisms that are motile or non-motile, rod-shaped, and able to ferment lactose to produce acid and gas at a temperature of 37 °C in a 48-hour incubation time. 42,43 The management and maintenance of WWTP greatly affect their ability to reduce total coliform content. The high total coliform in the effluent can be caused by the deposition of fecal sludge in the outlet basin that is never drained.…”

Evaluasi Instalasi Pengolahan Air Limbah (IPAL) RSUD dr. Soedono Madiun

“…Parameter total coliform yang termasuk dalam parameter biologi digunakan untuk mengetahui keberadaan bakteri, virus dan parasit dalam air. Nilai parameter total coliform yang tinggi mengindikasi adanya pencemaran patogen infeksius yang dapat menyebar melalui air yang disini merupakan air limbah rumah sakit [11].…”

The Effectiveness of Chlorine Tablets to Reducing Coliform in Wastewater Treatment Plant

“…Berdasarkan hasil pada Gambar 1, sampel air limbah pada inlet di IPAL memiliki nilai MPN >110000 sel/100 mL (>1,1 x 10 5 ), sehingga tidak memenuhi baku mutu yang dipersyaratkan yaitu 3000 sel/100 mL. Nilai MPN Coliform air limbah yang tinggi di Instansi 'X' disebabkan oleh sumber air limbah yang bercampur dengan air pencucian dan belum mengalami serangkaian pengolahan pada IPAL, sehingga untuk meningkatkan mutu secara bakteriologis perlu dilakukan pengolahan sebelum dibuang ke lingkungan atau badan air (Sulistiyawati, 2019). Sementara itu, setelah diberikan tablet klorin dengan variasi 100, 200, 300 dan 400 g, nilai MPN Coliform mengalami penurunan.…”
