Types of Water Treatment Applications
There are a number of different types of water filtration systems and options. But water filtration systems basically come in two types: Point of Use (POU) and Point of Entry (POE).
Point of Use Systems (POU):
POU systems are generally installed at the kitchen or bathroom sink. These systems can have one, two or three-filter housings with each housing containing an individual filter with a system flow rate of approximately half to one gallon per minute. A point of use system can be installed on the countertop or under counter. Depending on the type of water treatment you've decided on, there are POU systems for Reverse Osmosis, Ultraviolet and general water filtration.
Point of Entry Systems (POE):
POE systems are installed where the main water line enters the home. A point of entry system is commonly referred to as a whole house system, since the filtration it offers treats water for the entire home. Like a point of use system, the point of entry system allows for one, two or three filter housing with a system flow rate of 5 to 20 gallons per minute.
Just as there are a wide range of water-related contaminants, there are a variety of water treatment methods available for point of entry applications, including Ultraviolet, Reverse Osmosis and general water filtration.
