Cai X, Hu Y, Zhou S, Meng D, Xia S, Wang H. Water Res. September 2023. Highlights Secondary water supply systems (SWSSs) are crucial water supply infrastructures for high-rise buildings in metropolitan cities but are associated with increased microbial risks. The mechanisms of SWSS microbial ecology are less clear. Engineering factors such as tank… Read more »
By using the readily available system temperature hot water supply (>60C), the patented ILTDU, In-Line Thermal Disinfection Unit, from Horne Engineering facilitates the only effective thermal disinfection of showers, taps, TMVs, their associated pipe-work feeds, ancillary fittings, mixed water deadleg and terminal outlet fitting. In conjunction with high velocity flushing, which shears excess biofilm from internal pipework surfaces (and represents 95% of the water system’s total bio-load) thus improving water quality, regular operation of the ILTDU further aids the risk-management of retrograde pathogens, e.g. opportunistic Pseudomonas Aeruginosa, Non-Tuberculous Mycobacteria and others.
