Ultrafiltration
Here you will find our ultrafiltration solutions for homes and professionals.
Ultrafiltration is a widely used system in the field of water filtration. It costs less than a reverse osmosis system. It can be installed on its own or to support a water softener or an RO system.
Home ultrafiltration: what is it used for?
An ultrafiltration system mainly removes all bacteria and viruses present in the water.
The advantage of this system is that it produces no wastewater, can be installed to treat all the water in a home, and costs relatively little.
This system does not work with every type of water. Ultrafiltration is intended for rainwater, well water, and similar sources. Seawater or heavily polluted water is not suitable.
As a result, ultrafiltration is mainly aimed at people who want drinking water in several rooms of a home, at a lower cost, and with no wastewater!
Ultrafiltration: how does it work?
Ultrafiltration was developed in the 1970s by the dairy industry to remove bacteria and viruses using a membrane whose pores have a maximum diameter of 0.01 micron, which is 10,000 times finer than a human hair.
Ultrafiltration uses no chemicals, only physical filters. There is therefore no impact on the environment, and ultrafiltered water is safe to drink.
The different levels of filtration

We offer different ways to ultrafilter your water: a filter for the whole house and a point-of-use water dispenser, like reverse osmosis.
Ultrafiltration is more affordable than reverse osmosis and produces little or no wastewater.
For even better drinking water, we recommend installing an RO system downstream of the ultrafiltration system.
Ultrafiltration: how can you increase the flow rate of purified water?
|
An ultrafiltration system is limited to a certain flow rate. For example, for the model here, filtration capacity is limited to 1,000 liters/hour. Does your home's main water supply have a flow rate of 2,000 liters/hour, and do you want the same flow rate after ultrafiltration? It is very simple: in this case, you just need to install two ultrafiltration systems with a capacity of 1,000 liters/hour in parallel. |
