How to Maintain Your RO for the Best Performance?

A RO system is used for water purification widely through the world, both for residential and commercial purposes. The RO process is based on the theory of osmosis, but with the pressure reversed. The RO system uses pressure to push water through a semi permeable Reverse Osmosis Membrane Filter that separates out dissolved impurities. Only pure water is received in the output.

The reverse osmosis water purification is a well-established process that has been adapted by many large-scale water purification plants. The home filter system follows the same principle and produces the same standard of pure water as the large purification systems.

The three stages of RO

A simple RO system is basically comprised of three stages, namely:

• Pre filtering
• Osmotic membrane
• Post filtering

The more the advanced the reverse osmosis system, the more the stages for improved purification.

In the pre filtering stage, a filter cartridge separates silt, salt, and other residues. It is important to filter these fine particles out because these can build-up quite quickly and damage the Reverse Osmosis Membrane. A carbon filter will also be involved in this stage to remove any taste and smell from the water. Both these Reverse Osmosis Filter Replacement must be done every 6 to 9 months for the best results. If you don’t change these filters, gunk might reach the inner RO membrane and affect the level of water purity. You might get water that has an odd taste and odour.

Maintaining the central Reverse Osmosis Membrane

In the core, the RO system has a membrane. Water is pushed through the membrane at a pressure of 35 psi. The thinly perforated structure of the membrane pulls solvents from the water and only allows pure water to pass to the other side. This membrane is the central core of a RO and its maintenance is key to getting fresh purified water every time. You must clean your membrane every 4 months to prevent pores clogging. The membrane must be replaced every 2 to 3 years.

Post filtering

The post filtering stages are built to enhance the workings of an RO. They are used to further purify water and make it more palatable and to optimize the water to meet the regulatory standards. A carbon filter might be used at this stage to absorb all odours and unwanted taste. This carbon filter must also be replaced every 6 to 9 months.

Quick summary

• The optimum lifespan for filters is 6 to 9 months. Do not go longer than 12 months.
• The main Reverse Osmosis Filter Replacement must be done every 2 to 3 years.
• The plumbing pipes must be cleansed every 2 years.
• Keep an eye on the pressure nozzle during every check-up.

Low water output maybe evidence that your membrane or filter is running out of time. A properly maintained RO system can last as long as 10 to 15 years.
