Just replaced all my RO filters and I kept hearing constant water being wasted at an incredibly high rate. I found a tiny flow restrictive in my line, maybe the previous filter didn’t need much pressure so it worked before? But your video just helped me determine the importance of having a flow restrictor. I just ordered one based on your calculations. Thank you and I’m confident this will fix my problems.
I replaced all my filters but now water I m having tds of RO water is same as tds of tap water. What should I do?? Is sv not working or fr is not working??
Everything you said is wrong, Flow restrictor is used to restrict the water flow to create pressure on the membrane so that pressured water molecules can pass through the membrane pores, without the Flow restrictor the water just pass over the membrane and go to drain side and you will not get pure water.
What pressure does it create at the membrane? Does it depend on which restrictor one uses? Is the flow restrictor just a skinny tube on the inside? Thanks!
Not everything, his calculation is correct, but the reasoning is wrong. Using Lowe value flow restrictor would increase water wastage. Let's assume the inlet water has a pump of 700 ppm, the wastage water's ppm coming out of the ro membrane might be 800 approx when 350 FR restrictor is used, when using 450 FR it would be around 900+. So using the wrong Flow restrictor would increase water wastage.
@@ArunShankartheRealOne Sirji I think you told the correct reason but got I confused a bit on your example... Please note that you have mentioned 350 FR would result 800 wastage and 450 would result 900+. Here you are telling that if we increase from 350 to 450 then the wastage would be more? i mean from 800 to 900+? I am sorry to point this but doing it just to clear my confusion. Please don't mind, its not to proof you wrong, but to clarify my understanding
I do service for many RO residential systems in my city, most of them have 420ml flow restrictor and 75G memranes, TDS of input water is usually 350 to 500ppm and everything works fine, memranes last for about 3-4 years sometimes more. Usually I try to change the restrictor when changin 75 to 50G membrane and so on. Klaudio Berger very useful tips, thnx!
If FR value is higher, 450 compared to 800, then that means 800 is more restrictive than 450. I think such a conclusion should have been mentioned in the video. 800 FR is allowing more water to go through the membrane and less water is wasted via blue drain pipe. 450 will waste more water compared to 800. Higher FR value should reduce the life of the membrane IMO since it causes more water to pass through the membrane. More water passing through membrane means more wear and tear or higher possibility of membrane blockage which means lesser lifetime of the membrane.
No wrong ....fr blocks drain pipe ...if used 300 fr then water wastage would be less but system will work in high pressure ....more water will go through the membrane
@@mdfaisal216 I replied to you with a blog post that did all the calculations. It got deleted because it was a website link. You can google it yourself if you want. In short let me explain: The FR number means how much it will restrict the flow of rejected water. Higher value means it will force more water through the membrane. A 75 to 100 GPD RO membrane should use 800 FR. Less GPD membranes should use lesser value FR. Higher FR value means more water will be purified and less will be drained. So FR800 drains less water than FR450.
@@mdfaisal216 Whatever I said is mentioned on the supplier/manufacturers website. They have a table for what value FR to use for how much GPD membrane.
I just tried joining 2 FR of 450 in parallel and series both but did not make any difference. I noticed same amount of drain water and pure water coming out.
The Flow restrictor is added to the drain side not to the inlet side, the gasket seal is expanded automatically by the Booster pump pressure at inlet side........... I am sure you don't know anything how it works.
Thank you For 80 and 100 gpd membrane If I add again one more 300 FR after 450 it be comes 750 FR.. Will it work or damage membrane life. Can you give your suggestions. Am waiting for you Mr
Hi bro, Thank you for this video. I replaced a FR450 with a new one of same value which came alongwith new RO membrane. But I noticed a lot of water going waste and usable water flow was very low. When I connected the old FR alongwith new one in series, I am getting normal flow of usable and waste water. Is it that the new FR is defective or any fault other than FR?

Can you please explain more how a flow restrictor works and if an RO purifier does have it what will happen? Meaning কি, কি ভাবে কাজ করে, কি জন্য দরকার, না হলে কি সমস্যা ।
Flow restrictor is used to create pressure on RO membrane. There is one water inlet and 2 outlets(One is for for pure water and other is for waste water) in a RO housing. There is direct flow of water from inlet to outlet. Pure water is taken form membrane from pure water outlet. Now, to extract water through RO membrane requires high pressure. So if we not use flow restrictor, enough pressure will not build up and water will directly pass through outlet. So, by adding flow restrictor pressure build up inside housing and water squeezes through membrane and comes out through pure water outlet. Hope you understand.
i watched our most of the videos.now i want to buil ro+uv+tds water purifier at home. where should i get all the components. I am from Pune. Please tell me.
hello, nice video! if i'm running 2 100 gpd membranes in series, ie, waste water from 1st membrane feeds the second, what kind of flow restrictor should i get?
In series combination system work in 1:1 (clean : waste) you need only 300ccm . Calculate if both membrane work 30% recovery then take 100L(litter) and make 30L clean water and 70L waste In series that 70 went again in next membrane 21L clean and 49L waste So clean water 51L(30+21) and waste only 49L Means now system work 51:49 For your system 250ccm sufficient. So use 300ccm only
I just giving correct fr value for system on the basis of giving information Now one more data needed for considering membrane life waste water TDS If waste water didn't reached 1000+ TDS system can run with 300fr If waste water have more TDS than 1000 then use fr 550 only By using fr550 system run on 1:4

Brother use multiple post carbon filter it will make water taste sweet And if you want lower TDS water use multiple ro membrane 100 or 80 gpd membrane 1st and second will be 50gpd in series, Re-circulate second membrane product water to pump inlet with main inlet You will see your TDS drop and taste improve. Membrane life increase

Back pressure caused by the restrictor FORCES water molecules to be pushed through the membrane. This is bypassed when you want to flush the R/O surface to help it keep clear. This can add extra life of the R/O membrane.

Means now system work 51:49
For your system 250ccm sufficient. So use 300ccm only
actually you are correct to some extent, but the membrane which is prior will get damaged soon, due to clogging. if we do not give 1:4 rejection.
I just giving correct fr value for system on the basis of giving information
Now one more data needed for considering membrane life waste water TDS
If waste water didn't reached 1000+ TDS system can run with 300fr
If waste water have more TDS than 1000 then use fr 550 only
By using fr550 system run on 1:4
Good one Bro...👏👏👍
sir my to water is not sweet my TDS is 1800 to membranes 50 gpd CMS, filter ro with bio cera alkaline cartage 260 TDS but water is not sweet kindly tell me how to increase water sweetnees.i want little hard water.
+chingesh khan 1800 tds is to high . And product water is also high in tds.
Reviewmaza I'm asking you for solution,I knw this already,my tab water is 1800. n ro water is 260 with alkanine cartage,but water is not sweet,n flow of my incoming ro water is dip,so slow, m using csm 50 gpd membrane with 300 fr.
chenge your high tds ro membrane go with dow filmtech is the best for high tds,,,,,
Brother use multiple post carbon filter it will make water taste sweet
And if you want lower TDS water use multiple ro membrane
100 or 80 gpd membrane 1st and second will be 50gpd in series,
Re-circulate second membrane product water to pump inlet with main inlet
You will see your TDS drop and taste improve.
Membrane life increase
50gpd membrens which FR no can be use
+devendra bhattacharya Fr 300
75gpdmembrens which FR number be use..

Hi sir I am looking for a installation training
What stands for. 38
it is a value that is used for the calculation.
Back pressure caused by the restrictor FORCES water molecules to be pushed through the membrane. This is bypassed when you want to flush the R/O surface to help it keep clear. This can add extra life of the R/O membrane.
+Neonblue Industries correct
