Biofilm formation in domestic water systems is unavoidable, yet it can be effectively managed. Scientists have shown that, irrespective of the biocidal properties of the pipe-work material, approximately 95% of a water system’s total biomass is attached to its walls.
Chemicals treat only the remaining 5% free-floating, planktonic bacteria. Therefore, the practical approach to reducing biofilm is through high velocity flushing: upsetting the flow equilibrium, shear forces slough off excess biofilm, which is then carried away to drain. A flushing facility is integral to the Optitherm Thermostatic tap design. Find out more here.
