Will America embrace whole-house ultrafiltration?
There are obvious differences between point-of-use (POU) and point-of-entry (POE) water treatment products. For example, POE treats water for the whole house, or a majority of the house, while POU treats water for a single tap or multiple taps, but not a majority of the house. For POE systems, pressure drop is a major concern because most of the household plumbing is downstream of the system.

NSF/EPA project delivers cost-effective solutions to meet new arsenic MCL in Grimes, Calif.
According to Global Water Intelligence, an English publication, worldwide annual industry revenues are estimated at $420 billion, with the U.S. accounting for around $100 billion. This number is expected to grow as water becomes scarcer, and markets begin to mature. Two of the fastest growing segments are point of use/point of entry (POU/POE) systems and wastewater treatment.
Commercial POU installations improve drinking water quality in Grimes, Calif.
Until recently, using membranes for whole-house residential clarification and disinfection had not been an option for water treatment dealers. Technical advances made by Zenon Environmental in hollow fiber membrane technology for its large-scale municipal and industrial plants have changed this. Membranes are now being used in the company’s Homespring point-of-entry (POE) systems, providing a cost- effective solution for the removal of turbidity and pathogens, and delivering clear, biologically safe water.
