A Look at Reverse Osmosis Membranes
A Reverse Osmosis membrane is used in the process of filtering many different things from sea water to some gases.
However the most abundant use is for purifying household water and many properties now have such systems installed in their water system.
The membrane itself is the actual filter that operates to make water into a more pure state.
This is done by pushing the feed water very hard against the membrane, which being selective in nature will only allow pure water through and not things such as ions or particulates that are discarded through the waste system.
High pressure is used to force the water through and of course this needs a tough component to withstand this.
Two of the most commonly used membrane filters are hollow fiber and spiral wound.
All membranes work in a similar fashion and this is stopping materials passing through them of a specified or certain size of course this does depend on the filtration needed and the use of any resulting materials thereafter.
Of course in this case we are looking at water in the home.
A membrane such as this that is targeted at a specific use does have a few requirements, those being that they have to provide a big enough mass area for transfer, thus enabling the processing of large amounts from the feed stream.
It also must posses good selective and rejection qualities for different specific particles, it has to be made in a way that it is free from build up and clogging.
It also needs to be cost effective in manufacturing and reproducible in large numbers.
Although these systems offer a much purer water for our general consumption, there are a few downsides to them.
The biggest being the amount of waste produced by reverse osmosis systems in the home.
Only a Small percentage of purified water is harvested from them.
On average for every 5 or so gallons of end product produced in this way, between 40 and 90 gallons are wasted and flow down the drain and this can add to the daily amount already going through any septic system.
Another disadvantage is that once the water is filtered in this way, a lot of minerals that are good for our health are totally stripped away.
Thus in this way no benefit is gained from the pure water coming from this type of system.
So to conclude, although these systems are on the surface a good idea and do help in many ways in this world in areas such as industry and desalination plants, when it comes to the home and having one of these installed it would be an expensive idea indeed not just for the initial installation but in the upkeep and servicing.
But for the simple fact that it is so wasteful and apart from giving the hydration we all need every day the purified water has no natural nutritional benefits as they are removed during the process by the reverse osmosis membrane.
