Legionella Control Industrial Water Softener Systems

Legionella Control Industrial Water Softener Systems

Specially Engineered, Patent Pending, Legionella Control Softener Systems

NECO Legionella control water softeners reduce chances Legionella and other harmful pathogens grow by eliminating stagnant water in offline softener tanks and minimizing dead legs. Most commercial and industrial water softeners operate in alternating mode, having one softener tank online and the other softener tank, or tanks, offline, leaving a perfect breeding ground for Legionella and bacteria growth.

Legionella Minimizing Softener Systems Are Ideal For:

  • Hospitals
  • Nursing Homes
  • Medical Buildings
  • Hotels
  • Apartment Buildings
  • Surgery Centers & Healthcare Facilities
  • Correctional Facilities
  • Universities
  • Large Government Buildings

Standard industrial water softener systems have the following disadvantages concerning Legionella Control.

  • When the standby tank comes online, the bacterial levels are typically elevated increasing risks of legionella and other dangerous pathogen (disease causing organism) growth.
  • Water in the inlet and outlet piping of the standby tank has also been sitting stagnant for several hours to several days.
  • Piping design has not been optimized to minimize Legionella and pathogen growth.

The new Legionella Control Softener System doesn’t any of these disadvantages as neither softener is ever offline. This, paired with dead leg minimization piping design, results in minimum potential for Legionella and bacterial growth.

Performance and High Salt & Water Efficiency:

Since both water softeners are online all the time in series, better performance and higher efficiency can be reached. Lower brining rates can achieve similar water quality to that of higher brining rates with alternating softeners. Most industrial and commercial water softeners are regenerated at 15 pounds of salt per cubic foot of resin; this gives higher quality of water than lower salting rates but is not as efficient. Using a lower brine rate per cubic foot but flowing in a worker polisher design can reduce upwards of 40% of salt consumption vs. higher brining rates, while keeping hardness leakage minimized. The worker polisher design offers the following performance advantages in regard to hardness removal and efficiency.

  • 30-40% less salt is used to achieve the same water quality.
  • Less water is used in regeneration steps reducing water waste.
  • Continuous hardness leakage is minimized.
  • Endpoint leakage is lessened.
  • Starting point hardness leakage is also minimized.

100% Redundancy:

Since both softener tanks are online all the time when in service, if one tank fails to regenerate properly, the other tank would still soften the water with no lack of soft water at any time.

Flexibility:

Should a high flow rate occur, the second softener can be pulled online regardless of which unit is in lead or lag (worker or polisher) position and when flows reduce back to normal levels, the system returns a lead-lag configuration. The system is bi-directional, meaning either softener tank can be in the lead or lag position.
