Reverse Osmosis (R.O.) water filtering systems remove a wide variety of contaminants, including minerals, organics, and microorganisms.  While popular, reverse osmosis solutions must be evaluated versus your total water usage, level of problem elements and other factors unique to your situation.  We help New Hampshire and Maine customers determine their specific water filtering needs and propose long-lasting water filtering solutions which often require little or no ongoing maintenance, potentially including reverse osmosis solutions.

Reverse Osmosis Water Filtering Drawbacks:

Most reverse osmosis treatment solutions require 3-6 hours to process a gallon of drinking water.  Water temperature also greatly affects water filtering rates with 50°F water potentially decreasing R.O. system efficiency by 54%.

How They Work:

Water line pressure moves water through a semi‐permeable membrane which rejects charged particles and large molecules while allowing water and small organic molecules to pass through the membrane.  Most of the filtered impurities and other contaminants are rinsed to a drain while the resulting refined water is routed to a special holding tank.  Note that R.O. systems are usually used in conjunction with water softeners or activated-carbon filter.

Effective at removing:

Inorganic elements such as dissolved salts of sodium, ferrous iron, fluoride, nitrate, lead, and some organic contaminants.  Most reverse osmosis water filtering systems will also remove suspended solids, bacteria and viruses.

Ineffective against:

Various organic molecules and water taste and odor issues.

Risks:

  1. Bacterial growth can occur in the post-treatment storage reservoir.

Chlorides and sulfates can ruin otherwise pristine drinking water with salty water taste.  According to the EPA, in higher concentrations chloride can corrode piping and very high chloride content in tap water causes blackening and pitting of stainless steel sinks.

Sulfate concentrations can also produce a salty taste in tap water.  Sulfates, such as magnesium sulfate and sodium sulfate, can also have a laxative effect for persons who are not acclimated to such water and produce hard scales in boilers and water heaters. 

Hartley Well Drilling installs the CSI Water Microline Reverse Osmosis (R.O.) system to treat salty water taste.  This system also filters moderate levels of other contaminants including iron, manganese and sodium.  

CSI Water’s Microline R.O. system features a patented design that directs water flow through each filtration step without the need for tubes or fittings.  This design also contains a water-saving automatic shut-off, drain control and safety check valve, making the unit easy to maintain and service.

The Microline® also features a patented membrane seal which allows easy, tool-free replacement.  Contact Hartley Well Drilling to explore water filtering solutions including reverse osmosis systems and other long-lasting water treatment options.
