Reverse Osmosis Systems from Celtic Water Solutions

Providing an extensive range of reliable, highly specified reverse osmosis filter systems

Water often has unseen impurities in the form of bacteria, viruses, cysts, minerals, and other contaminants which make it unfit for drinking. Often the water is treated which removes most of these impurities, however, leaving a noticeable taste and odour to the tap water. While it is a common problem for most households, it doesn’t make the most appealing way to quench your thirst.

With an increasing number of problems in drinking water reported in Ireland every year, it becomes essential to improve the water quality in your home. Here comes reverse osmosis water filtration technology.

What are reverse osmosis systems?

Reverse osmosis is a water purification process that removes unwanted contaminants, solid substances, large molecules and other unwanted particles from water by using pressure to push it through a specialized membrane. Installing a RO system delivers clean and filtered water straight from your kitchen tap. The semi-permeable membrane is designed to remove 99.9% of known contaminants from water. The additional filters remove odour and improve the taste of filtered water. One of the biggest advantages of a reverse osmosis water filter filtration system is its efficiency. It is the best way to ensure clean and filtered water at a fraction of the cost of bottled water.

How Do RO Systems Work?

At CWS we provide an extensive range of reliable, highly specified reverse osmosis water filter systems. Reverse Osmosis Systems are used most commonly to purify drinking water. It does this by removing salts and other impurities to result in improved colours, better taste and improved properties of the water. Reverse Osmosis systems employ a mixture of conventional cartridges and cross flow membranes with 3 to 5 filter cartridges combinations. Reverse Osmosis (RO) uses a semi permeable membrane. This semi permeable membrane allows the fluid that is being purified to pass through the membrane. As it does this, it rejects the contaminants that remain. It utilises a technology known as cross flow.

Cross flow allows the membrane to continually clean itself off. As fluid passes through the membrane, some of it continues downstream. This causes the rejected and unwanted particles to be pushed away from the membrane. RO requires a strong driving force to push the fluid through the membrane. Most reverse osmosis systems require a booster pump to force water through exceptionally small pore sizes in filter cartridges and membranes at high pressure. This ensures you only get pure drinking water.

What Do RO Filters Treat?

Reverse Osmosis systems successfully treat water with dissolved minerals and metals such as aluminium, arsenic, barium, chloride, chromium, copper, fluoride, magnesium, iron, lead, manganese, mercury, nitrate, selenium, silver, sulphate and zinc.

Effective with asbestos, many taste, colour and odour producing chemicals, particulates, total dissolved solids, turbidity and radium. When using appropriate active carbon pre filtering (commonly included with most RO systems), additional treatment can also be provided for such volatile contaminants as as benzene, MTBE, trichlorethylene, trihalomethanes (THMs) and radon.

How much does it cost for a reverse osmosis system?
