Reverse Osmosis Filtration

  • Reverse osmosis (RO) is the industry standard process for water purification and is an extremely effective, economical means of producing filtered water whatever your requirements may be.
  • RO is a cost effective, safe way to purify your water; seen by low operating costs, no chemicals being involved and minimal maintenance once installed.
  • Our RO systems force water through a semi-permeable membrane to remove dissolved ions, larger particles and any undesirable molecules that can be found in your water supply.
  • Reverse osmosis effectiveness is due to its filtering capabilities rated at 0.0001µ. Contaminants removed by the RO process include both dissolved ions and metal ions, such as, sodium, chloride, copper, calcium, magnesium, nitrate, fluoride, lead, potassium, nitrate, sulphate and many more.

Reverse Osmosis Q&a's

What is removed by a reverse osmosis system?

Reverse osmosis systems remove dissolved ions and metal ions which are often undesirable contaminants that you do not require in your water supply.

Our RO filtration system will reject the following;

Sodium, sulphate, calcium, potassium, nitrate, iron, zinc, mercury, phosphate, lead, arsenic, magnesium, nickel, fluoride, chloride, manganese, cyanide, arsenic, aluminium, copper, arsenic and many more.

How does it work?

Reverse osmosis works by using pressure to force water through a semi-permeable membrane to purify the water. This membrane filters down to an incredible pore size of 0.0001µ and results in the rejection of dissolved ions and metal ions found in your supply. As the feed water is forced at high pressure through the semi-permeable membrane it separates into a permeate flow (treated water) and reject flow (drain, unwanted waste water). The unwanted rejected water is disposed off and the permeate, treated water is sent to be used.

How much waste water will there be?

This varies on the size of the ro unit. IWE strives to use the latest advancements in membrane technology to ensure that waste water is kept to a minimum at all time.

For domestic RO systems there can be as much as 50% rejected water which will go to drain.

2L incoming = 1L waste & 1L of treated RO water*

Commercial and Industrial RO systems have a far less rejection rate, typically at 80% recovery, meaning a 20% rejection rate.

2,000L incoming = 400L waste & 1,600L of treated RO water*

*example figures

What are the ongoing cost implications?

Ongoing costs are minimal. Typical costs include replacement filters where required and either a membrane clean or membrane replacement when the membranes begin to fail.

How long does a reverse osmosis membranes last for?

Unfortunately, this is a tricky question to answer due to many incoming factors affect this such as the incoming water quality (temperature, pressure, contaminants present), volume being used and how often the system is being used for.

Typically if the pre-treatment is correctly designed a membrane will have a life of 2 years.*

*average life, can vary.

What sizes do you offer?

We supply domestic systems through to bespoke reverse osmosis units up to 50m3/hr of treated water.

Any size system we can cater for.

Where are these manufactured?

We are proud that these are UK manufactured and are vigorously tested and quality checked before leaving our factory. We take pride in our units and only use the highest quality of components.

At IWE we are always striving to be ahead of the industry and are always up to date with technological advancements in the water treatment industry. Product development is something that we take very seriously.
