Water Treatment Equipment - Reverse Osmosis

Reverse Osmosis is one of the most tested and consistent drinking water filtration methods known today for either home or business applications.

IWE have developed a complete range of RO water filters, developed, designed and manufactured in the UK at our Matlock branch in Derbyshire.

With unbeatable recovery and efficiency we believe that our new range of RO drinking water filters are the most cost effective and efficient units on the market today.

Our entire range features :

  • Fully programmable controllers.
  • 316 stainless steel frames and pipework.
  • Stainless inlet filters.
  • Stainless steel membrane housings and end caps.

Better still, because we produce our units 'in house' we are able to customise any of our filters specifically to suit you, plastics can be changed to any colour you wish and we can even add your company logo if required.

Our standard RO range is in stock meaning we are typically able to deliver your water filter within a few days from order.

Should you wish to see our water filters in action please feel free to contact us. We are happy to invite you along to our premises and show you exactly how our RO units operate and also provide training and advice on which filter would best suit your specific application.

 


The IWE Range

Compact Range ROCompact

The IWE compact is the smallest RO water filter in our range, with Permeate flow rate up to 150 l/ph.

Featuring all the quality components of its bigger brothers in a smaller footprint the compact RO comes fully factory tested and set up to your own specification. Simply connect the feed water to the ro unit and begin.

Compact IBC

Compact IBC Range ROWith the same RO filter as the compact unit the compact IBC has the addition of an IBC tank situated underneath the membranes.

The compact IBC has proven to be a big hit with companies such as distilleries requiring filtered water, typically leaving the RO unit in production overnight and having 1,000 Litres of reverse osmosis water in the IBC ready to use the next day.

The compact IBC features the addition of a high level switch situated within the tank which ceases water production when the tank is full.

Industrial Water Equipments guide to Reverse Osmosis

Guide to Reverse Osmosis

Over the years Reverse Osmosis (RO) has become popular choice for both domestic and commercial filtration, this increase has been partly due to the increasing advancements in technology and affordability of not only in the reverse osmosis units themselves but also replacement parts such as the RO membranes. Our guide will hopefully dispel some of the myths and help to answer some of the more common questions we are asked regarding this method of filtration.

What is reverse osmosis

What is RO?RO filtration is the opposite of a naturally occurring process known as osmosis, whereby a solution passes through a semi permeable membrane to a higher concentrated solution. Osmosis takes place throughout the natural world including plants where osmosis is used to extract nutrients from within the soil in which they are placed.

When pressure is greater on the higher concentration side of the water flow then the natural process of osmosis can be reversed, hence the term reverse osmosis. Instead of dilute solution passing through a membrane to a higher concentration (osmosis). Concentrated water (your incoming water feed) is pressurised though the use of a pump and forced through a housing containing a semi permeable membrane, water molecules pass through this membrane which becomes your clean filtered water and is referred to as 'permeate', which leaves behind a solution containing all the contaminants too large in molecule size to pass through the membrane. This concentrated solution, referred to as the 'concentrate' is then passed down to drain.

Reverse Osmosis as an effective method of filtration and is successfully used over a wide variety of industries where high quality water, free of contaminants is paramount and delivered at a consistent level of quality, from distilleries to laboratories RO has been the filtration method of choice.

What does reverse osmosis remove

What does ro remove?In general terms when used as a standalone filtration method reverse osmosis has the ability to remove an extremely high percentage of a vast spectrum of contaminants including Calcium, Magnesium, Nitrates, Lead and Sodium as well as bacteria and viruses such as Cryptosporidium, E. coli and Norovirus, in fact any particle larger than a water molecule won't have the ability to pass through an ro system.

For industrial applications and dependent on your water quality requirements reverse osmosis can be used in conjunction with additional filtration methods such as a water softeners or carbon filters to continuously deliver filtered water to any specific level of quality.

Bear in mind however, RO is not selective in it's filtration process, therefore it isn't an ideal solution to target specific contaminants, for example if you have a need to remove calcium from your incoming water supply then a water softener which is specifically designed to produce soft water is a much better choice.

How long does a reverse osmosis membrane last

How long does an RO membrane lastRO membranes are able to last for many years without ever needing to be changed, however the longevity of a membrane is largely dependent on the quality of water your reverse osmosis water filter is being fed with. The higher the contaminants contained within your feed water the harder your membrane(s) have to work, and therefore the shorter their lifespan.

In recent years membrane technology has significantly advanced leading to a dramatic reduction in the cost of replacement membranes. This reduction has made replacement much more cost effective, typically a membrane which might have cost thousands just a few years ago would now only cost hundreds to replace. There are ways however in which you can protect your investment and prolong your membrane(s) life.

Pre filtration

A standard practice with RO is the implementation of pre filtration. Depending on your water quality a number of pre filtration stages should be considered, this can be determined by a simple test of your incoming water feed. Following water testing our team of engineers can advise you of the correct action to take when considering reverse osmosis and pre filtration. One of the most significant chemical elements which needs to be removed from your water is Chlorine. Even trace elements of Chlorine can lead to a dramatic reduction in permeate quality and ultimately premature failure of your membrane(s). If Chlorine is detected then installation of a simple Activated Carbon pre filter will eradicate the damaging effects of this chemical.

Will reverse osmosis remove salt

The process of removing salt from water is known as desalination, and yes an RO water filter is more than capable of performing this process, in fact RO was originally invented to do this very task. However desalination requires the use of specialised Sea Water reverse osmosis membranes, therefore it's important to understand and specify your intended application prior to purchase.

Industrial Water Equipment are able to modify any of our standard range of ro's and customise them to suit your specific requirements, we also have to ability to retro-fit or upgrade any of our reverse osmosis systems to fit in with the changing needs of our customers.
