Reverse Osmosis Drinking Water Systems

Mr. Water Professional Water Treatment of Maryland sells and installs high quality GENERIC TYPE Reverse Osmosis drinking water systems for homeowners and business offices. We typically install 5 stage R.O. Systems with a 50 gallon per day membrane and a standard 3.2 gallon (larger sizes available) pure water holding tank. We can also custom design an R.O. water purification system with a higher purity membrane to meet your needs. These systems can be installed under a kitchen sink or in your basement under certain circumstances.          

These systems were first investigated for industrial desalination of seawater using membranes at UCLA over 65 years ago. The Reverse Osmosis Process has now been scaled down to modify and improve small volumes of water in the home for drinking and cooking purposes. Water is squeezed under household water pressure through a semipermeable membrane and the treated water is stored in a special 3-4 gallon holding tank for use, while the reject water containing the unwanted substances is disposed of down the drain.

 In most cases a single drinking water faucet is installed at the kitchen sink, also a line can be run to the ice maker/cold water dispenser on a refrigerator. For every gallon of treated water that is produced – approximately 3 are rejected as waste water, therefore whole house Reverse Osmosis Systems are not only impractical but pure Reverse Osmosis water is very aggressive and will cause problems for most household plumbing systems.

Reverse Osmosis Systems operate on water pressure

Because reverse osmosis systems operate on water pressure, the higher the incoming water pressure is the more water can be produced and interestingly – the purer the water will be. The type of membrane the RO systems uses and how much water is produced by the membrane also determines the purity of the product water; a system that produces more water like one containing a 100 gallon per day membrane will not have the purity of a system using a 36 gallon per day membrane.

Reverse Osmosis Systems are very reliable

These systems have become very popular in recent years because of greatly increased reliability and improved membrane performance. Many homeowners choose RO Systems for the removal of nitrates, lead, pesticides, herbicides, from uncertain well water systems. The service interval of these systems are based on how thoroughly the water to be treated is filtered before entering the unit, the amount of water used annually, the rejection rate and the amount of TDS present in the raw water. Most properly installed and sized systems need to be serviced with filter changes every 1-2 years and the membrane replaced every 4-5 years.
