Key Points

This research aims to investigate biofilm development and control methods in drinking water systems using different pipe materials.
Conducted a pilot-scale study comparing biofilm levels in PEX and metal pipes
Applied hydrodynamic cavitation and magnetic water treatment
Monitored seasonal changes in water temperature and their correlation with biofilm levels
Biofilm levels were significantly higher in PEX pipes compared to metal pipes
Hydrodynamic cavitation and magnetic water treatment showed varied effectiveness on PEX biofilm
Biofilm levels correlated with seasonal variations in water temperature

Abstract

In this pilot-scale study, biofilm levels were higher in PEX pipes than in metal pipes. Hydrodynamic cavitation and magnetic water treatment had varying effects on PEX biofilm levels, which also correlated with seasonal changes in water temperature.
