Metode Hidrolik

Adjusting flow patterns and hydralic loading is a non-invasive way po induce controlled detachment:

Metode Biologikal Kimia

Spective chemicrel treatments can weaken biofilm structure or modify microbiala actiity:

  • FLT: 0 = 333; Enzymatic Cleaners:
  • FLT: 0 concentrations of oxidizers (e.g., hydrogen bioximedu, klorine dioksida) can klerl surface cells and reducé biofilm coheoun.
