ProMinent® Chlorination Package

Water Treatment Systems for Building Re-opening

The Problem

The Corona Virus Pandemic has caused a multitude of problems in many sectors of the US. The stay-at-home rules and the abandonment of hotels, offices, manufacturing plants and many other facilities have left these building's water systems in a low flow or stagnant state. The potential for microbiological growth is greatly increased and with it the possibility of pathogens, such as Legionella being present. The presence of these microbes in drinking water, showers, cooling towers, etc. is a very real concern from a health and liability point of view.

The re-opening of these buildings will require flushing of all runs and fixtures if they have not been properly maintained and flushed during closure. A more aggressive approach utilizing a disinfectant such as chlorine will be more prudent and reduce liability.

All government agencies recommend flushing the water system, but for reduced liability and increased safety, hyperchlorination should also be considered.

A ProMinent® chlorination control system will increase the likelihood of success and may reduce your liability by maintaining a constant residual and having data logs recorded, which validate your treatment process.

ProMinent® is a leading supplier of chlorine control systems in municipal and industrial applications. We have packaged control systems available specifically for this application. These ProMinent systems will provide a consistent chlorine dosage in a circulating or non-circulating system and data log these readings. The ProMinent system can also be used at different points of use throughout the facility to document chlorine levels before and after chlorination.

Outside Resources


  • Turnkey approach- all necessary devices arrive mounted on a panel; just provide power and the sample water
  • Proven accuracy, reliability and durability in municipalities for many years
  • Portable system that can be easily located in different areas of the facility
  • Datalogging and graphing for reduced liability and on-site verification of the process
  • Remote communication - via cell modem or LAN to track the progress of the treatment
  • EPA approved method for "on-line" chlorine monitoring

These chlorination packages in conjunction with ProMinent® chemical pumps will provide a superior level of confidence that the water in your building or cooling tower is "ready for use" when used in accordance with EPA recommendations and administered by a water professional.
