Lineguard

The Lineguard filters water at the point where it enters a facility or home to guarantee high quality, safe water for those circumstances in which the water quality is not secured or additional treatment is required (e.g. hospitals). It removes viruses for >99.99% (log 4) and bacteria for >99.99999% (log 7). The capacity of one LineGuard system is 60 l/min at 2 bar (24 gpm at 45 psi), depending on the feedwater quality. The long service life provides up to 5,000 m3 (1.3 million gallons) per system.

  • Operates on water line pressure, no pump required

typical use

The quality and safety of water entering a building is of vital importance, especially when the source of the water is below standard or the use requires a higher quality. The LineGuard produces safe, purified water for applications where high flow rates, long service life, low maintenance and compact design are important factors.

Typical applications can be found in healthcare centers and dentist offices, where people are at a particularly high risk of infection from waterborne pathogens. The LineGuard is used in hotels and restaurants to guarantee safe and high-quality water, and in residential water treatment to improve tap and well water quality.

The LineGuard is built around reliable, state-of-the-art ultrafiltration (UF) membranes modules. The modules consist of billions of microscopic pores, small enough to retain all micro-organisms, including bacteria, viruses, and cysts, sediment and turbidity, but large enough to allow vital minerals to pass through. The system is expandable through parallel connection of up to five systems, and service is required just once a year. 

scope

The core of every LineGuard system is built around reliable, state-of-the-art X-Flow ultrafiltration (UF) membrane modules, which are successfully used in the world’s most advanced water purification plants. 

With carefully selected partners, Pentair develops innovative and ready-to-use membrane solutions that meet both regulatory and financial KPI’s. 


As one of the world’s foremost membrane technology knowledge centers, we share our scientific know-how and practical experience with our partners to make the difference in challenging filtration projects. 

Fields of application

The LineGuard is developed to filter water at the point where it enters a facility or home to guarantee high-quality and safe water. It can handle high flow rates, even at lower water pressure. The initial flow rate (depending on the incoming water conditions) is 60 l/min @ 2 bar (26 gal/min @ 29 psi), sufficient for four tap connections. It works on waterline pressure and has a built-in controller for automatic backwash and forward flush cleaning cycles.

The LineGuard can be used for:

  • Drinking, product and process water

  • Hospitals, healthcare centers and dentist offices (particularly high risk of infection from waterborne pathogens)
  • Hotels and restaurants, to guarantee safe and high-quality water for drinking, food preparation, showers and laundry
  • Legionella prevention for showers in public buildings
  • Whole-house water treatment to improve tap water quality for drinking
  • Well water treatment
