I currently run an omnipole pro 300gpd r/o with booster pump.
I have a requirement to produce 1000ltrs of pure 5 days a week
and it does not hack it .
Is there anything I can do to boost production??
or do I need to upgrade to a better R/O
If an upgrade is required what is the best one ??
Any advice guys
Cheers Russ

[russ_clark]

anyone offer any advice ?

Russ,

If what you mean is 1000 litres per day - my opinion is that you'll need to upgrade to a Merlin or a 4040!

There the only 2 that I know of that will give you that level of production but someone more knowledgable might be able to add to that list.

Hi Alistair
Yes I need 1000 litres per day x 5 days per week
Thanks for your input
Hopefully the tech guys will throw in some advice.
Cheers Russ

Hi Russ, if you are looking at 5000ltrs a week then really the 4040 is the one to go for.

It is possible with a 300gpd system but remember 300USGPD = 1134ltrs so 1000ltrs would really be pushing the ro to its limit.  A merlin will easily produce 1000ltrs of pure a day but if your tds is high then you may not get the rejection levels that a 4040 will give you.

My recommendation is a 4040.

Thanks JM123
my tds is around 500 in and 15 out
the ro has an aquatec booster pump.
I have just measured the production and it took 6 mins to fill a 2 litre bottle!
So thats under 500 litres a day !
No wonder I am running short.
The membranes and filters are 6 months old
I have new filters that I will be changing at the weekend.
Will that make any difference at all??
With the Merlin and 40/40 I have heard the waste is very high?
I am on a water meter so need the best from the r/o I buy

WAter Meter 

Have you thought about rain water collection 

[Bazzy1999]

Russ.. I run a 40/40 ro and its set at 50% pure 50% waste and it fills my 1000L tank in around 5 hours.
My tap tds is around 300 and mains tap psi is 90 and after 40/40 my tds is down to 004 then polished off to 000 and im on a meter aswell 
Hope it helps in some way.

Use an IBC tank to collect your rainwater from your guttering to save water usage if you're on a meter.

I have a pumped 300gpd RO and I achieve around the same rate as you - 6 minutes per 2 litre bottle (20 litres per hour which is about 480 litres per day).  As I work on my own I manage OK  with that though.  If I have some heavy days on back to back, I work it so that I fill up in the evening to allow the RO  to produce overnight.
I have a horrible feeling that you may have to live with highish waste levels in order to reach your production target.

[JM123]

500 in is pretty high - your best setup would be a water softener into a 4040, if your mains pressure is low then you'll need a booster pump as well.

Hi Russ
  I got a 4040 with booster pump and it gives 1000L of very pure water in about 5 hrs.  My tds will be about the same as where you are.

[russ_clark]

Looks like I have got to upgrade then guys
water softener? 4040 ro? booster pumps?
where did you guys get yours and any prices?
cheers

The water softener 3500L and ro with booster pump was around £1700 ouch.

But it makes more pure water than you could shake a stick at.

[JM123]

we can supply the 4040 stainless steel built for £650 with steel pushfit connectors.  For a softener I'll need to get back to you on a price, as for a booster pump the mori pumps we supply are £580 but many on here use the clarke which I think is about £210.

[russ_clark]

what is the difference in waste between the 40/40 and the merlin please
tech guys?

[neil100]

Wow 300 in and 4 out.

mine cant get any where near it. I have a 4040, 17 months old. tap tds 76in 16 out. I also have a Clarke booster pump, New filters dont make any diffrence. My ro is on the way out I think.

I was going to get the 300gpd RO man and pressure regulator pump also from RO -man. This seems cheap at £80.  Should I get better booster pump?

[JM123]

the pressure regulator pump is a booster pump, it will keep the pressure high to ensure max production - my advice is don't bother, the very minimum you want to be looking at is a merlin - which is a very good system but depending on the makeup of your water your tds out may be relatively high.

Mine has 256 tds in and the inline tds is 7 tds out  that's a 4040 with booster pump that's probably a Clarke
