Self-purging Bacterial Regrowth Inhibitor, Water Quality
Enhancement
and Sample Collection System
Hydro-Guard® is a self-contained apparatus for purging low-quality water from both potable and non-potable water systems for the purpose of maintaining desired or required water quality standards and preventing bacterial regrowth. The apparatus also provides a highly reliable water quality sample collection point, which reduces the potential for false positive samples through the apparatuses continual purging action. The purging action reduces the potential for contact or time-based chemical reactions or bacterial regrowth to contaminate the carrier pipe from the water main to the sample collection point.
As a result of the design and/or operating conditions, water distribution systems develop dead ends and low flow areas. These areas permit time-based chemical reactions and bacterial regrowth to compromise the water's chemical and microbiological quality, esthetes, as well as the health and safety of the public.
The Hydro-Guard apparatus provides an effective and economical means of automatically and/or remotely purging low flow areas of water distribution systems. The system uses both internal automatic and/or external chemical and bacterial analysis to determine system activation, run time and deactivation.
The system uses a unique housing configuration permitting storage of the system's primary components below ground in the lower water tight portion of the housings. The lower or below ground portion of the housing provides protection and security for the system's primary electronic, electric and mechanical components from vandalism, weather and traffic hazards. The upper portion of the housing contains the system's data access and programming port, manual chemical, bacteriological monitoring and sample collection point as well as the energy dissipation and directional flow component.
The system uses a time and or remote telemetry and/or electronic sensing capability to electronically activate the system flow valve, thereby allowing low or deteriorating quality water to be automatically or remotely purged from the water distribution system. During the process, the potentially damaging kinetic energy contained in the high pressurized water stream is dissipated and the flow stream disrupted and channeled so as to permit passive discharge in the immediate area without injury or damage to property.
Providing this activity on a continual, consistent or periodic seasonal basis will assist water distribution systems in maintaining regulatory and/or operational water quality standards in dead ends and/or low flow areas of water distribution systems.
