Solving the Common Issues of Reverse Osmosis Systems

Reverse osmosis (RO) is a widely used water purification method that removes contaminants by forcing water through a semi-permeable membrane. While effective at removing a broad range of impurities, including microplastics, heavy metals, and dissolved salts, which is great use in home aquariums, where aquatic pets benefit from water completely free of added minerals and contaminants, reverse osmosis systems have several potential issues and limitations that users should be aware of. 

Common Issues with Reverse Osmosis Systems:

1. Water Wastage:

One of the most significant drawbacks of reverse osmosis systems is the high level of water waste. For every gallon of purified water produced, RO systems can waste three to four gallons of water, which is discarded as brine. This inefficiency can be a concern, especially in areas with limited water resources or for environmentally conscious users.

2. Removal of Beneficial Minerals:

RO systems remove not only harmful contaminants but also essential minerals like calcium, magnesium, and potassium. The result is “demineralized” or “soft” water, which some argue is less beneficial for health since it lacks these vital nutrients. Additionally, demineralized water can be more acidic and may have a flat or bland taste.

3. Slow Water Production:

Reverse osmosis systems generally produce water slowly. A typical under-sink RO system might take hours to fill a storage tank, making it difficult to meet high water demand quickly. The rate of production depends on the system’s efficiency and the water pressure. Keep in mind, cooking a pot of pasta normally drains your tank.

4. Maintenance Requirements:

RO systems require regular maintenance to function effectively. The filters and membrane must be replaced periodically (typically every 6-12 months for filters and 2-3 years for the membrane) to prevent clogging and maintain water quality. Neglecting maintenance can lead to reduced performance, bacterial growth, and even system failure.

5. Cost:

The initial cost of purchasing and installing an RO system can be high. Additionally, ongoing costs for filter and membrane replacement, as well as potential professional servicing, can add up over time. While RO systems are cost-effective for producing purified water, they can be more expensive than other water treatment options, especially for large households.

6. Environmental Impact:

The disposal of used RO membranes and filters contributes to plastic waste. Moreover, the wasted brine water, which contains concentrated contaminants, is typically discharged into the sewage system or the environment, potentially impacting local water sources.

7. pH Imbalance:

Reverse osmosis can lower the pH of water, making it more acidic. While this is generally not harmful, it can affect the taste of the water and, in some cases, cause corrosion in plumbing if the water remains in the system for long periods. Also a caution, the permeate water will typically be 1-2 points lower than the feed water ph.

8. Complex Installation:

Installing an RO system can be complicated, particularly under-sink models. Professional installation might be necessary, adding to the overall cost. Furthermore, space constraints under the sink can be an issue for some homeowners.

While reverse osmosis is an effective water purification method, it is not without its challenges. Users should weigh the pros and cons, considering factors like water wastage, maintenance, and cost, as well as the potential need for supplementary filtration to address specific concerns like mineral content.

The Pure Way Solution

Pure Way Filtration Systems remove all the contaminates from the water with none of the downsides of RO systems:

  1. No Wasted Water: 100% of the water entering a Pure Way filter exits as useable, pure water.
  2. Installation is easy: Pure Way systems:
    1. Do not require electricity
    2. Do not require hook up to your sewer line
    3. Do not require a separate faucet or drilling holes in countertops
  3. No need to sanitize the system or engage in difficult, expensive maintenance procedures
  4. Pure Way systems do not remove the minerals from your water.
