Water Filtration / Reverse Osmosis / RO Affiliate

After you said that yesterday, i rang him back and asked how much waste there is and he said 1 gallon waster per 4 clean water.
I think those figures might be pie in the sky though.
But screw it, I might aswell just get it while it's going cheap.

[brenmurph]

the waste water is correct.. as the water flows to the tank or tap the ro filter has a gadget to backflush.  you can pipe the water to the drain or to a container ( water butt) if ur concerned about waste.

[LordEoin]

I was more concerned about the very low level of waste quoted.
I've heard that these things can sometimes produce up to 12-20 times more waste than water.

I bought it anyway. The free delivery arrived next day.
It's fairly simple to put together, but I need to wire in a socket for it.

I'm interested to see how it works out, clean vs waste water.
I never did the pH tests the day I was talking to you, work got in the way.
Bren, do you find a lower pH with your RO water?

[LordEoin]

Just plugged in my flux capacitor. Havent brought it up to 88mph yet, but soon I'll be able to go all the way to the distant future of 2015 where I'll get my hoverboard.

@ john...never tried it and ive run out of ph strips... ordering more

@LordEoin is that pumped? U mentioned a plug but I can't make out a pump. Let us know what the throughput is when you measure it? Looks identical to my own

[johnrm]

Look here...

Thx John! I'll be interested to see the system flow rate. I was close to buying this at one point http://www.vyair.com/Scripts/prodView.asp?idproduct=129
Had a good chat with one of their sales guys. They seemed very honest about what performance to expect which was nothing like the membrane rating

[brenmurph]

this is the cheapest source, exact same unit.
Unless u have poor water pressure pressure u dont need pumped system.

non pumped is down to 169 euros

Dunno Bren, that unit has 50GPD membrane not 100. Ive very good pressure throughout my house and theres no way my un-pumped system will deliver enough water for a brew(33Litres ish) in 1 day, thats why I was investigating pumped systems. The vyair systems are actually used for window cleaning so I expect they would have a good flowrate. Also they use 2 X 100GPD membranes in parallel(I think), giving a much larger theoretical output. I fill 5L containers a few days in advance. Ive been told that thers also differences in membrane quality but not sure about that once the rejection ratio is what its meant to be.....

[brenmurph]

Hardly.. Would need to be careful with specs..Takes about 3 hours to fill the 2 gallon tank so no hope of getting 50 or 100 gallons per day.
Had the pumped one...Took it out... More pressure with the un pumped. Its a great pump tho..Can be used for a transfer pump albeit takes a while.

Ask the others how long it takes to fill.
The membrane may let in 100 galls but it gets exponentially slower as the tank fills.
Empty the ro system by leaving tap on. When empty the water will trickel out. Leave it trickle into a 5 gallon container...Now u know the actual capacity.
Twin ro filters may speed things up.
It may be easier to tap off 2 gallons the night before into a sterile container. Take another two next morn and another two later near brew time thatll give 6 gallons and u dont need to take a chance on an english supplier and the shipping costs.
Another option for ro fans ust get a second hand well pump tank, 10-20 gallons

EDIT: used http://convertcase.net/ - Tube

I've read that the unpumped version wasted more water, and the pumped version will fill in 45 minutes.
not tested the refill rate yet.

[LordEoin]

75 minutes - 9.5L filtered water - 27.5L waste water
flourine smell gone completely

Edited out tired rant against water2buy's customer support.
