Reverse Osmosis Water Dispenser

A proper reverse Osmosis Water dispenser has many individual stages for the water to be filtered through. The complexity of a reverse osmosis water dispenser is dependent upon how many steps are in the process. Most reverse osmosis water dispenser systems have four or five stages. A lot of the difficulty when it comes to these systems has to do with the prefilters that are in place to keep the reverse osmosis membrane from becoming clogged. Replacing the filters can prolong the life of the system. The stages of a typical home based reverse osmosis water dispenser system are as follows:

 

First a sediment pre-filter is used to extract the larger contaminants from the water. These contaminants include rust, dust, dirt, and sand particles. This will reduce any turbidity, or cloudiness, in your water supply.

 

Next, you may choose to outfit your system with a second carbon pre-filter. These filters are used to remove most of the chlorine and organic chemicals from the water. This will give the water much less of a chlorine taste and odor. This will also help protect the chlorine-vulnerable reverse osmosis membrane.

 

Following is the reverse osmosis membrane. This is typically made from a thin film composite membrane. This is used to collect the water that has been filtered. An unfortunate effect of this membrane is that the trace minerals found in the water will be removed. We need these trace minerals to supplement our nutritional value.

 

You may choose to outfit your system with a carbon post filter. This filter is used to capture chemicals still present in the water. This will also help against any tainting which may occur within the water Storage Tank of the unit. This final Carbon Filter will most assuredly remove any remaining synthetic chemicals in the water.
