4040 ro set up help
« on: November 13, 2013, 07:08:51 pm »
The last 6 years wfp i have used a 300gpd and 2xmerlin units.
I havnt a clue what im looking for with a 4040 setup.
My water is 300-360ppm from tap and water pressure is at 40 psi.
Is it as simple as buying a 4040 housing and membrain??. And having 1x carbon and 1 x sediment filter running before membrain??.
Whats dofference between hf4 and hf5??.
I have seen the ez ro and am liking it but cant find any reviews...
Thanks in advance for any help.

3 pre filters as you would have had on your 300gpd r.o.
Hf5 is designed for low mains pressure, most of the time you'd be better off with a booster pump with a hf4.
Tap to adjust waste to pure ratio so giving you a definitive tds reading is impossible as this varies depending on what you set the ratio at and the pressure you're running.
The pure tds will be alot lower than your merlin though saving resin

(Must point out i dont have a 4040, been reading up on them as thinking i may get one soon)
Why don't you have a quick google before making stupid comments?

For me, yes it was as simple as that on paper. In practise it was totally different.

I bought the components I wanted and assembled it myself.

Now I would buy a ready kit that you assemble - the kit will contain all the bits and pieces you will need. Daqua had a good price on them when I last looked.

I opted for the 20" prefilters. I reasoned that a 20" carbon block had more surface area available to remove chlorine than a 10" filter. My water pressure is 40 psi and our tap tds is 100 - 125. I choose an HF5 membrane for the lower water pressure although PureFreedom did advise that at 40psi both HF4 and HF5 will perform the same.  

TDS after r/o but before di is between 1 and 2 depending on the tap tds on the day. I have a 6.5 litre di vessel. The resin was put in last September and still going strong. My r/o performs best at about 55% waste to 45% pure which gives me 2 litres a minute of pure. It would be recommended that with your higher tap tds, you will be better off with a higher pure to waste ratio, but higher water costs need to be seen against reduced membrane life.

I would go the 4040 route rather than the 4021 route. If you needed to upgrade, then you will find that replacing 2 x 21" membranes are much more expensive than a single 4040.

I do not have a booster pump.

Added:

We are at the end of the water line in our Cul de Sac. The pressure isn't as high as it is in other places in our town. We also don't have the best of water volume either. I run 2 prefilters, 1 sediment and 1 carbon block. We have a high amount of sediment in our water, so I chose to fit 2 pressure gauges, 1 on the inlet and the other after the carbon block. Even with new filters fitted, there is a pressure difference between the inlet and outlet gauges. However, as I ordered clear filter housings, I can see at a glance when filter is getting dirty and needs to be changed.

I joined the prefilters together and they are secured to a double bracket. The inlet and outlet hoses on the prefilters are quick release, which enables me to take them out of the r/o cabinet as a unit and change the filters on a table in the back garden.

I have hf5 4040 and I added a booster pump I got from lidl for 49.99 .

Boosts it to 70-80 psi and makes a world of difference with lower tds output and much faster production .

My tap tds is higher than spruces though at 200 -250 so the difference it makes may depend on your tap tds .

Lovely, cheers for help. Appreaciated.
Im getting the hump with 37 ppm coming out of my merlin all the time as just throwing money away in resin...
How low tds should i expect with a 4040 with it being 300/360 from tap??

Cheers.

This booster pump is the biz! It takes my 35 psi water pressure to 105 psi and as a result filters my 375 tds reading, through a 4040 RO, down to 1 or 2 ppm.

Excuse the mess, I'm experimenting.

its a very rough estimate but you should be getting in the region of at least 95% rejection rate.
If you take your higher tds reading from tap of 360 ppm then worst case scenario is 18 ppm after ro, although it could be lower if pressure is good.

My tap is approx 270 and after 4040 without a booster pump and a mains pressure of about 60 psi I get between 12 and 14 ppm.

Can any of yous with the 4040 of static tanks can we have some pics to get some ideas please
Thanks

Hi Nick,
Where did you get the booster pump from. Is the boosted pressure adjustable because at 105psi you must be using and HF4 membrane?

Have a look at Spruce's 4040 static set-up:

You won't find many other well thought out and efficient set-ups that are better than that one in my opinion.  ;)

I'm sorry Spruce, but all I can tell you is that I bought the pump from RO Man.

cheers Nick.

The one from pure freedom seemed to be much more complicated as it appears to have a bypass mechanism included to reduce pressure to what you require. It was also very expensive.

Hence the HF5 route for me.
