What is Point-of-Entry Filtration?

LiquiTech's SAFETGARD® self-cleaning water filtration system improves incoming water quality by removing sediment, corrosion, and biofilm deposits at the point of entry. Damage caused by sediment and iron-based corrosion particulates can be extremely expensive and time-consuming to repair. Our unique process starts with a sediment analysis to determine the right solution for your facility. Compared to traditional filtration technologies, LiquiTech's SAFETGARD system can save up to 90% more water and involves far less maintenance and inspection.

Why is a Point-of-Entry Water Filtration System Important?

Municipal water is transported through a large and aging infrastructure, which can alter water quality dynamically and unpredictably. Variations can be caused by changes in source water; seasonal events such as heavy rains; infrastructure age; hydrant use; and degradation due to time, distance, temperature and other environmental factors. These variations result in sediment and biofilm entering building water systems, which can cause large increases in operating costs related to your water infrastructure, long and short-term damage to water-using equipment, and increased risk of bacteria. Systemic sediment control can be achieved effectively through point-of-entry filtration.

The following equipment is prone to failure due to sediment build up:

  • Boilers
  • Chillers
  • Sterilizers
  • Dialysis equipment
  • Food service equipment
  • Point-of-use filters
  • Ice machines
  • Hot water heaters
  • Pumps/valves
  • MRI/X-ray machines

The SAFETGARD® automatic self-cleaning water filtration POE system continuously monitors real time operation, effectively removes sediment, helps reduce biofilm and corrosion particulate, while optimizing your water quality and saving your facility time and money.

An evidence-based approach to water filtration

We start with an in-depth analysis of your water system to assess risk and determine your specific needs. We prescribe only what is necessary to protect your water environment. LiquiTech’s sediment testing uses a laser particle distribution test to analyze and identify all the water points of entry to determine the volume, surface area and amount of all suspended solids entering the buildings. This test can help in determining the potential for nutrients that foster microbiological growth, among other issues.
