Whole House Reverse Osmosis

Whole House RO - complex, expensive, and rarely recommended

I am often asked about whole house reverse osmosis and wanted to give you a glimpse of the complexity of such a system.  I provide this photo for you in order to give you the perspective that might be missing in a brief discussion of the topic.  Whole house reverse osmosis need not be difficult to operate but it is much more complex to rely on than a whole house water filter such as my Urban Defender. Also, a whole house reverse osmosis system will cause a higher electric bill than a whole house water filter system due to the addition of the water pump. There will also be more maintenance than with a whole house water filter. I recommend against using a whole house reverse osmosis system unless the contaminants in your water are so dangerous that you have no other choice. You may request specifications from me by emailing.

Why use it?

Sometimes whole house reverse osmosis is the only option. Extremely high total dissolved solids can be among the most common reasons to employ whole house reverse osmosis. Other issues may include high sodium (a component of tds) and a mix of other contaminants like fluoride, radioactive metals, or nitrates.

This photo illustrates the actual reverse osmosis system on the left. Note the permeate pump just above the canister holding two ro membranes on the right.  There is a sediment filter in front of the membrane.  The water then travels to the right where the almond colored tank is an acid neutralizer to raise water pH.  Next is water storage tank based on an estimate of peak daily water usage.  Note the pump on the right. This pump delivers pressurized water to the home.

High iron or hardness also require additional treatment for removal prior to the water entering the whole house reverse osmosis system.
