Filters for ro

[tench0771]

Just got new filters

3 pre filters
4 300gpd membranes

£697

From Virotech

Does this sound weight or have I been shafted ?

 

[tench0771]

£76 for pre filters
£621 for the membranes ?

I’m thinking rip out the 4 small membranes chunk a 4040 low pressure in as there cheaper

 

[doug atkinson]

That’s a higher price than the Axeon 500 GPD. However they will not fit in that membrane housing. So you could have done 2 x 500 GPD membranes and housings for half price ?

 

[tench0771]

Hi Doug it’s a 1200gpd will that still produce the same output with your 500 filters ?

Hi Doug it’s a 1200gpd will that still produce the same output with your 500 filters ?

@tench0771 how long does it take to produce 1 litre of pure with what PSI.

 

[tench0771]

I’ll have to check tomorrow Doug but it’s set to 100psi

 

[tench0771]

Hi Doug here is the out puts

Tap output. 00:06.60 per 1000mil
Ro output. 00:24.68 per 1000mill

Ro set 100 psi

 

[doug atkinson]

@tench0771 that’s good, presume that’s boosted. What’s your rejection rate after RO.

Downside to that system is 4 membranes which will be costly for you.

A 4021 membrane will give the same output but you’ll be paying for 1 membrane from £200 to £400.

 

[tench0771]

Can I add the 4021 to that system get rid of the 4 filters Doug? Yes it’s boosted I’ll have to do that tomorrow as tank full now c?

 

[doug atkinson]

@tench0771 you could possibly do that. What is the booster pump, can you post photo of the label.

[tench0771]

I also have 3 different filters on front all 20” most systems have just 2 with your 4021 filter will I still need all 3 pre filters?

 

[tench0771]

Hi Doug my waste is

00:18.38

 

[doug atkinson]

@tench0771 . You really don’t need an activated carbon filter as that is more to do with taste in drinking water. You could add another carbon or sediment in its place.

I would presume the use 3/8” hose so that would be suitable to attach to the 4021 however 1/2” is better.

 

[tench0771]

Thanks Doug how much is the 4021 filter and housing as can only see the hole 4021 system?

 

[doug atkinson]

Housing your looking at around £120, membrane from £175 to £370.

 

[tench0771]

Perfect I’ll get them order at some point soon as already payed for the other ones ?‍. Look forward to changing over to this 4021 sounds much better thanks for all your advice should have just came to you first place

 

[tench0771]

Hiya Doug apologies for more questions I’ve been looking at your systems and was wandering with my tap pressure and flow how many letters would these produce per hour with out booster pump?

 

[doug atkinson]

You are looking at a litre 130 secs at 30 PSI.
