Problem Identification

The following problems have been identified:

  1. Heavy rusting prevails in the piping system.
  2. As per process requirement water is processed through RO.
  3. As an adverse effect of pure water, there is high level of attack on MS lines resulting into heavy corrosion.
  4. Several photographs taken at source and application points.

Probable Causes of Corrosion

As such there are so many causes of corrosion, but several that relates in our case are as follows:

  1. Water Purity: Water that is produced via reverse osmosis tends to be aggressive. This product can affect metallic pipes and other substances that dissolve and ionize in water – not due to its acidity, but because of its high purity and lower levels of dissolved substances. The lower the water’s level of dissolved substances, the more aggressive the water is.
  2. Sulfate-reducing bacteria (SRB) are bacteria that can obtain energy by oxidizing organic compounds or molecular hydrogen while reducing sulfate to hydrogen sulfide. Most sulfate-reducing bacteria can also reduce other oxidized inorganic sulfur compounds, such as sulfite, thiosulfate/elemental sulfur. Sulfate-reducing bacteria is the most important microbe for anaerobic corrosion of buried pipelines in soils. SRB can remove molecular hydrogen from the cathode, leading to cathodic depolarization of the metal surface. Iron sulfide or scale by SRB is accumulated on surfaces of metals, which accelerates the dissolution of the iron.

Project: Initiated by the New York City (NYC) Department of Design and Construction (DDC), July 2011 for the Brooklyn Children’s’ Museum (BCM).

The BCM has an Open Loop Geothermal system for heating and cooling the building.

The BCM geothermal system was experiencing water treatment quality problems prior to the installation of the rings, which endangered the viability of the system. Iron, other mineral deposits, including bacterial biofilm forming on the well screens, particularly the diffusion well screens, reduced flow and eventually made the wells ineffective. The Wellan® rings were installed to determine if the device would be able to reduce bacterial and mineral buildup on the well screen and minimize future deposits on associated piping.

Installation: Wellan® 2000 Rings (6 inch pipe diameter) installed on the supply and return water piping at the BCM.

Testing Methodology: In order to measure the performance of the Wellan® rings, the following BCM system parameters were selected for monitoring from February 1, 2010 through June 31, 2010. The same parameters were monitored over the period December 2010 to May 2011


  1. System flow rates with the HVAC system manually adjusted for a full well water flow condition.
  2. Well water supply pressure.
  3. Well water return back pressure.
  4. Periodic well water quality testing.
  5. Deterioration of any of these parameters would indicate that the Wellan® rings may not be working.

Results: Independent Review and Reporting was performed and completed by independent emelson consulting engineers.

Test Results:

  1. System Flow Rates – indicated no signs of deterioration for the observation period of May 2011 to June 2011 (no appreciable change in flow rate as of Nov. 2013) . The well water treatment system performed well throughout this period with no reported problems.
  2. Well Water Supply Pressure – well pump discharge pressure and heat pump supply header pressure showed some variation from month to month but did not indicate a tendency for increasing which would be an indication of building system flow blockage.
  3. Well Water Return Head Pressure – return pressure had increased substantially from measurements made in 2010, currently 14 psig vs. 5 psig in 2010. This increased back pressure in the diffusion wells is attributable to the silt buildup.
  4. Visual Inspection of Problem Valve – When the problem valve was removed from the system on June 27,2011, there was little to no iron buildup on the valve.

Wellan® Ring 2000 Results
DECEMBER 2, 2014

Problem: Legionella spikes. Required frequent cooling tower maintenance.

Installation: Installed 3 rings
1 – Condenser Water Supply
2 – one on each of Cooling Tower’s Spray Heads

The Wellan® 2000 is a ring-type device which is clamped on the outside of one or more pipes through which the water is flowing. According to the inventor and the manufacturer, the principle of operation is based on quantum physics, and the principle that each atomic particle in the flowing water gives off a unique, and distinct ‘signature’ frequency pattern (vibrations/oscillations). The manufacturer in Germany, using a laser and proprietary engineering software technology, imparts a new “active” oscillation for each type of substance in the water or fluid.


The goal of this research project is to evaluate the potential use of the Wellan® 2000 water treatment device to control the formation of mineral scale, metal corrosion and biological growth in cooling tower water systems used as a means for heat rejection for building cooling systems at New York City facilities. In the Spring of 2012, the Museum of the City of New York agreed to allow the installation of this device as a test case for this project. The Museum uses an open loop cooling tower water system for rejecting heat from its chilled water system, and prior to the installation of the Wellan® 2000 water treatment devices had used chemical treatment to control scale, corrosion and bacteria growth buildup as is typically done for cooling tower water systems in most buildings. The Wellan® 2000 is a ring-type device clamped on the outside of one or more pipes through which the water flows. According to the inventor, Clauss Wagner, the technology operates based on the principles of quantum physics, and the basis that each atomic particle in the flowing water gives off a unique, and distinct ‘signature’ frequency pattern (vibrations). Based in Germany, the manufacturer uses a white laser and proprietary process technology to impart a new “active” oscillation for each type of substance in the water whereby this process reportedly prevents bacteria buildup and scale formation on metal surfaces. The rings are composed of magnesium, aluminum, silicon, and other metals and are warranted for at least ten years. No internal or external energy source is required to operate the Wellan® rings. In order to measure the performance of the Wellan® rings at the Museum of the City of New York, DDC retained Kallen & Lemelson to monitor system parameters from April 1, 2012 through July 2014. The results are reported herein.
