RO System - Is this any good ??

[RichC]

This is the system I was considering when I got pissed off filling bottles in advance(doesn't really bother me now). It doesn't use a storage tank so should fill boiler very quickly. The supplier was very responsive and helpful when I emailed them.

I would be very careful about flow rate, I ve been using RO for several years and cant see how it can work without a tank to be honest. Even with 2 RO membranes and a pump I think theres little chance you will get an endless flow of water and the 100 gallon a day is a little optimistic. It may be worth digging a little deeper.
If ur near kildare drop over, I have 3 systems, one pumped and your post gave me the idea to take an RO off one double up on another so I have a pumped twin RO as in your post and see how it flows. I cant understand why you wouldnt have a tank anyway. Why not consider a normal RO system and a tank the size you need? I might ring around. Wouldnt it be great if we could get a 5-gallon storage tank instead of a 2 gall that comes with an RO system?

Just be careful you end up with something that works as you want it. The price is dear considering theres no 5th filter and no tank included. Ring Water2buy in galway and see can they sell u a a kit with 2 tanks

I'd be inclined to avoid the tank if I could for brewing. I understand with a domestic unit because you mightn't want  a pump coming on every time you pour a glass of water but for filling HLT it'd be fine. I'd love to know what difference the 5th filter unit makes to the water. Heres a mail that the guy from vyair sent me and he says itll give 20~30litres per hour

Richard,


We do have an RO-200 that will give yo a flow rate of 20-30 litres per hour but it can't be left for 6-8 weeks unused.
In fact no RO unti can be left this long safely, as membranes will become damaged by lack of use and bacterial film.


The RO-50mp I think will give you around 7 litres per hour .


You could replace this large unit with your existing RO that can give you the domestic warted but also the higher output for the brewing operation, and then there would be no problem with lack of use.


Have a look at this link.

We would set it up so you could have 2 different outlets if needed.
Kind regards

The fifth filter is a coconut shell filter that puts some taste back into the water and a small amount of minerals potentially.

The domestic RO systems are supplied with pump or without pump. For those with low pressure mains a pump can boost pressure otherwise not needed. T

The water is not stored in a steel tank it is in a bladder inside the tank. the tank is pressurised to something like 12-15psi and that is how it is dispensed, under its own pressure. The pump on the RO unit is to supply adequate pressure to the water coming in as far as I know.

The RO systems have quick connect fittings and it is possible to add a secons RO membrane to try to flow twice as much water, I would still like to know why 2 tanks in parallel or a bigger tank wouldnt work perfectly.

I agree that you cant dispense 20 litres to make a brew and leave the system idle. My units are used in my house and gym and used regularly. I get 2.5 gallons from a tank or thereabouts and if I need more I fill from my other system.
With a pump the tank takes 2 hours to fill. once again I would be sceptical of a fill rate of 20-30 litres an hour even with two RO membranes doin the work.  I would have to see it to believe it!

Anyone wants to see a close look at the RO systems working please let me know, Im in Kildare near kildare town.

They are a great bonus for a homebrewer and cheap to buy for what you get and they (the sytstem) last forever u just maintain the filters as necessary.

and lads all the RO systems are made in china.
PLEASE consider buying from Irish supplier. They are in galway, free shipping and all their products are cheaper than UK Guaranteed. www.WATER2BUY.ie

I have no affiliation with the company but I have bought dozens of these units for my clients.

Give them a ring and ask for homebrew modifications ( bigger tanks and so on, I'm sure theyll help.

Interesting feedback on the frequent use - luckily I have a fish tank which needs RO water as well ..

So hopefully we can keep it ticking over every couple of days.
