Standing Up Against the Hard Water

Setting up a reverse osmosis (RO) membrane filter system presents a wealth of advantages when it comes to producing potable water. As a matter of fact, many municipal water systems have them too. However, the presence of hard water threatens to undermine the membrane filters in so many ways. To beat that menace requires a deeper understanding of it, so to speak.


Hard water is known for packing high levels of minerals such as manganese, calcium, iron, and magnesium. In numerous amounts, they can cause scaling inside the water supply conduits and stress the RO filters due to the increasing amount of water pressure. Take note that since RO membranes have two sections to increase the filtration quality, the second membrane can be stressed or damaged as well if the primary one is severely contaminated from the scaling.


The prime solution to combating hard water is to test the water samples in the area where a filter is expected to be installed. Detecting amounts of a certain hard water component will be key to putting up pretreatment filters, which will do the initial work for the RO filters. For instance, chlorinated hard water requires carbon filters at the main point of entry.

Learning which areas are marked as hard water will make a difference in installing a RO system that lasts. With ample knowledge and research, you have the power to make things possible.
