Detection of Biofilm Layers in Water Plumbings and Determination of its Effect on Water Quality

Water quality deteriorations in the plumbing are mainly resulted from accumulations and biofilm layer formation on pipe surfaces. Biofilms may cause significant health risks human due to its pathogen content. In this study, plumbing, presence of pathogenic microorganisms biofilms their effects water were examined by membrane filtration with dehydrated medium (NPS) method 22 different buildings a facility’s network. A relation deterioration age material was also studied. The results expressed as colony forming units (CFU). According galvanized metal pipes, average count determined >200 CFU/250 mL, calculated 107 mL highest observed. For PE (Polyethylene) found 145 mL. No physical chemical changes PPRC (Polypropylene Random Copolymer) neither physical/chemical change nor growth total 34 Biofilm detected at 15 points Pseudomonas aeruginosa most common pathogens 12 buildings. Escherichia coli, which four 600 colonies. It has been observed that more occurred surfaces, microbiological higher than pipes.
