New 40/40 ro

[Eviestevie]

Between 70 and 80psi

I always get better pressure at night for some reason

 

[AGlassAct]

That's some good water pressure you've got eviestevie! I'm lucky if I get 40 in the evening! You must have the perfect parameters for that membrane as it's virtually at it's optimum rejection. Keep us updated mate I'm very interested to see how good these membranes are in the long term

I worked out that with the price which was half of all the over competitors that if and when I need a new membrane which shouldn't be any time soon

I have cash left over for 2 4040 hf5 membranes

He was a really decent bloke and said he will look after me with filters in future

He also said window cleaning is something he will be taking more seriously in future with specific products

At the moment he said most of his business is hydrophonics and drinking systems but windows buy these systems even tho he advises against

 

[AGlassAct]

The figures look good mate, I'm very impressed so far. Hooked up to my booster pump (takes it to 110psi) that membrane should last a fair few years for me! Thanks for the input eviestevie - much appreciated!

In the past I have ordered several things at once and they have bunched them together and reduced the postage by a fair bit, excellent service.

@Eviestevie membrane seems to be producing efficiently. The housing is the same as Vyair but they use a membrane we know very little about. Vyair use a good quality membrane recognised in the cleaning industry.

Is this 40/40 system going to provide better water quality than a twin di set up ? I know twin di produces 0ppm but it doesn't have all the filters like this kit so does it remove as much from the water like a 40/40 ?

You need to understand how an r/o works. Once you understand that then the rest will start to make sense.

Under ideal conditions an r/o removes around 98% of the minerals from the water. The remainder is then polished off with a di vessel filled with resin.

So if you have tap water with a TDS of 200 ppm then you could expect pure at 4ppm which will be polished off by the resin. If you have an r/o with a di vessel, the resin in the di vessel will last a long time as it doesn't have much work to do.

So if you had a double di vessel working with 200ppm tap water, then you are going to use a lot of resin to process that water down to 000 ppm.

If you have double di vessels and you use 1000 liters of pure water a week on a water meter, then you will pay for 1,000 liters of water plus the resin to purify it.

If you have an r/o and di vessel and the r/o is set to a ratio of 2 waste to 1 pure, then it will cost you 3000 liters of water that week, 1000 liters pure and 2000 liters waste. However, your resin costs will be minimal.

So a double di with fresh resin is more efficient than an r/o, but the cost to produce water per liter will be cheaper than just using di. If it wasn't, then none of us would use an r/o.

Double di purification with soft water is rather convenient. It can also be a solution if a cleaner is living in a mildly hard water area but only uses a small amount of water a day.

Spruce you seem very clued up on your Ro's so wonder if you can help me.

I have a new static system from pure freedom it has a booster on it 2 pre filters,40/40 and then d.i.

I filled it up for the first time and all was good.I have a inline tds metre tap water is around 400 so very high the ro brings it down to 9 and the o after d.i

I gave it a quick flush yesterday then filled for second time and after d.i the tds has crept up to 1.

Now this is no major problem but I would have expected it to remain at 0 for a lot longer.

Do you have any idea what could have caused it to rise so quick?

 

[clearview]

Ok spruce I understand all that, what about quality of water will a twin di clean the water as good as an r/o as r/o have different filter and membrane etc to clean the water where as di is just resin ?
