Considering building water systems have not changed much since they were first thought of in the middle ages, it is hardly a surprise that one of the major threats to the ability for any facility to effectively clean and disinfect is the building water.   Biofilms attach inside of water and drain lines and given the oippoirtunity of stagnation and heat, biofilms grwo as do manyt microorganisms that find the biofilms support them too.  Biofilms and the diverse organisms that colonize within them comprise the biggest contributing factor to the transmission of infectious water borne pathogens including parasites, protozoa, virus and bacteriological species such as Legionella pneumophila.  Legionella is commonly found infecting thier favorite hosts - protozoa (amoeba) which feed on biofilm.   Pristine™ Water Circuits are the first best -practice potable water circuits  in the world to leverage the critical role of water movement to reduce the likelihood of biofilm attachment.  Some buildings circulate hot water loops that they run at 130ºF to kill legionella. But ambient water (CW) is rarely circulated.  When all of the water stops flowing - it warms to whatever the ambient temp around it.  These temops are incubation temps and plenty sufficient to promote biofilm growth and ammplification of themicroorganiosmsto which thebiofilm providing habitat, safety and shelter to pathogenic microorganisms.

 If instead, these dead-end trunk and brach distribution systems used our proprietary Pristine reversable and "nested" potable water circuits, they would find there is no need to heat the water beyond a comfort temperature like 110ºF.  We have two, soon three major international Journal Publications featuring our systems; one in theJournal of Hospital Infection Control and the other in the Journal of Dentistry.  A new abstract featuring one of thecomponents of our Pristine hand hygiene stations will be released for publication in January.

  We begin by completely deconstructing municipal water at the point of entry to the building.  Every Pristine water circuit uses RO permerate bothforfeed water to our ECA equipment,but also for our diluents to ensure maximim efficacy of the anolyte disinfectant with minimal salt residue. Our pretreatments remove all physical, chemical and microbiological contaminants from the water leaving a source water that is nearly equivalent to distilled and is deionized water.  From there we rebuild it to very tight specifications, which exceed US and international drinking water requirements such as the NPDWA, and the Safe Drinking Water Act. . Primarily, we add electrolytically generated anolyte (HOCl; a non-toxic halogen), which is an approved GRAS ingredient for water disinfection.  Our advanced systems automation enable connection to BACnet and other building automations, and provide a convenient resource for ISO 22000 and 45000 documentation compliance with their entire buildings water supplies.   Our mst recvent installation,commissioning and turn over occured on October 1st of this year, when we turned our latest Pristine water circuit over to Columbia University Medical Center (CUMC) at the Vanderbilt Clinic, College of Dental Medicine.  Previous installations of our Pristine™ water circuits are installed the EU, including at Dublin University/Trinity College, where entire building are provided with our sterile, "Pristine" , prisintes are serve  Specific "kits" are added for cooling tower application.  A variation of the building Pristine Water Circuit® is our process water systems used in food and beverage manufacturing, processing and packaging.
