In the laboratory there is used Membrane Filter Method& Multiple Tube Method for the determination of Facal Coliform. Besides Membrane Filter Method is widely used In the laboratory, because this method is comparatively easy and less costly and time consuming for the determination of Facal Coliform in the water sample than Multiple Tube Method. Direct result is found for facal Coliform in Membrane Filter Method. The suitable temperature is about 440 c for the determination of facal Coliform in water.
The value of Facal Coliform obtained from Membrane Filter Method& Multiple Tube Method should be identical for the same sample. The value of Facal Coliform is equal to TNTC.
According to Bangladesh Environment Conservation rules (1997), drinking water standard for Facal Coliform is 0 /l00ml; according to WHO drinking water standard for Facal Coliform is fully absent condition. In the sample Facal Coliform concentration is not within acceptable range. So the water sample may be required additional treatment for highly Facal Coliform contamination.
