Water fed pole system

Hi

My current set up is the ro / resin

My water tank is filled up with normal tap water which then goes to my 4 ro units. Sediment carbon then I believe carbon block and sediment again. It then goes to my 25l di vessel which is full of resin.

All works spot on no complains what soever

But I find myself buying resin every 2-3 month.

Does anyone have any advise on other set ups ?

do you not have any places near you that sell the water all ready purified...there's place near me called wfp in basildon, I fill my 500ltr tank £10...most window cleaners thay use wfp on my area all go there to fill up....when first started out got told as we live hard water area we would go through our filters and resin really quick and the cost of resin and filters and hassle making water just wasent worth it....this place is real cheap in comparison to one I looked up in London.. £30 to fill tank up there.

Please can you put up a photo as the description of your system is very confusing.

There are 2 ways to process water. R/O then di and secondly, di only.

Your r/o setup will be tap, sediment filter, carbon block filter, r/o membrane housing/s with membranes inside and then di vessel to polish water off to zero ppm and final water tank.

The second way is filling you van's tank with tap water and pumping that through a di vessel on its way to the brush head. This setup will be; tank filled with tap water, pump, di vessel, hose reel, brush head. You will be using the di vessel full of resin to purify your water as you need it to clean windows.

I fill tank with tap water this goes to ro unit then to di then to my hose/brush

I have a 250 ltr tank... The resin costs me £70 around every 2-3 month... There's no where round my end (Stockton on tees) that does purified water to fill up

Basically then your r/o system isn't working. Stockton on Tees has a tap water tds no more than 150ppm so I see the resin doing all the work.

If you are filling your van's tank with tap water then you can't use an r/o between your tank and pole. You can only use a di vessel.

The correct procedure with using an r/o is; tap, r/o, di then van tank. Your tap water pressure is what 'drives' the filtration process of your r/o. Your r/o has membranes that in it that filter the minerals from the water. Filtered water goes out of the pure outlet and waste goes out of the waste line from your membrane housing at the same time. The waste pipe must never be closed off as that water flushes the filtered minerals away down the drain.

What r/o have you got?

Think its sediment then carbon then carbon block then sediment again.. The tank full of tap goes to these then through the di to my hose reel.. Can you send me photo of any suggestions just feels like I'm paying a costly price when other cleaners i talk to say their resin lasts about 9 month

There is no ro in that pic

That is just various pre filters which will do nothing to reduce tds only the resin is doing that

You would need an ro membrane and housing to accompany the pre filters and have that between tap and tank then through di either before tank or between tank and pole

 
Why sediment ,Carbon ,and then sediment again ?? Thats not necessary.

Sediment is for bigger debris , which is filtered off by the first filter the sediment filter, the second filter the carbon block takes away chloramine and other finer stuff, and then to the RO ,and DI if it isn't pure enough. So the sediment after carbon is excessive and pointless..

Now you are on the right track, but this is too small to produce water for window cleaning. It would be ok to fill a fish tank.

I don't normally stick my neck out but to set up an r/o system is going to mean a financial investment.

If you want to go down this route then you need to consider a few things.

Ideally you can use a small r/o system provided you have a place to store water. A small r/o system filters water very slowly so most of us start off with a used (but clean) 1000 litre IBC tank and process water into that overnight and whilst out working. If they need more water during the day its a trip home to top up. A clean IBC tank will cost about £50 plus another £50 for transport if you can't collect it..

We did this and have it in the garage but some cleaners have them in an outhouse or a shed. Someone else I know has his in the back garden painted black to slow algae growth inside.

We also got a transfer pump and hose so we were able to pump water from the storage tank into our van tank. Most windies use a submersible pump.

Here is a typical 450GPD r/o for window cleaners.

450GPD REVERSE OSMOSIS WATER FED POLE WINDOW CLEANING

We upgraded to a 450GPD r/o soon after we went wfp and at 40 psi water pressure and without a booster pump we were able to fill an IBC tank in around 34 hours in winter. Hence the reason why you need a storage facility.

We also fitted a float switch and solenoid valve so the water to the r/o would switch off automatically when the IBC tank was full.

We found processing water this way was enough to supply the 2 of us with just enough water.

We have now upgraded that 450GPD with a 4040 which performs much faster. We get 2LPM of pure so filling an IBC tank will take about 8 hours.

Things to know to make an informed decision.

1) You should know what your water pressure is at the tap and how much water you get through the tap in a minute.

If your pressure is low then it may mean you will need a booster pump which is added expense.

2) Are you on a water meter?

This is a valid question as its all about costs. In Stockton with reasonable water pressure (50 psi +) you will be able to set up your r/o system to a waste to pure ratio of 1 to 1.

This means that to produce 1 liter of water requires 2 liters from you tap as the other liter flushes the filtered minerals removed from the water down the drain.

3) Have you got storage facilities?

If you haven't then you will need to process water directly into your tank. This means you need a faster r/o which will cost more. Most suppliers suggest either a 4021 or a 4040 for this.

4) Are you able to keep the r/o frost free if permanently fixed into the van?

If a membrane freezes up then its destroyed.

5) Is this worth the hassle?

You are spending £20 on resin a month. For me it was. We are not on a water meter and our tap water tds is between 99 and 125ppm. I have an HF5 membrane in my 4040 system and that take the pure down to 2ppm. A bag of resin to polish the water off to zero lasts 4 years.

But the cost to set this up was around £1300.00 back then. My resin usage would be more than yours as we use about 450 liters a day, but you have to decide if the long term investment is worth it.

I have my r/o in a heated cabinet on the wall in my garage. A tube heater keeps my r/o cabinet at 8 degrees in the winter.
