sorry about that will see if they can lower the music. I can here it on my end - if needed we do have the CC at the bottom to follow along

Bad seal bad membranes or control issue. Unfortunately couldn't tell you with out reviewing the system.

we have a whole series for troubleshooting on youtube - th-cam.com/video/iq5GnC2y-w0/w-d-xo.html

Ideally, never. However, most water softeners say that they have a life span of about 30 years, and this is mostly limited because of the resin. As long as you take proper care of your softener, you shouldn't really need to replace your resin and it can outlast more than 30 years. Taking care of it includes things like making sure it always is full of salt and that it doesn't completely run out. Make sure you wash your system every 4 months or so, and don't have a lot of iron or other solids enter Your system (you can do this by installing a water filter before your softener). However, if your softener has been mistreated and/or is older, it may be a good idea to check the quality of the resin. If it is not good, then you'll likely need to replace it.

There is a slit in the permeate tube and it travels through that.

it is like a bag, a pouch. clean water diffuses into pouch and exits from the tube.

@@erdem-- a bag filter only has one inlet and one outlet. A RO Membrane has one inlet and (2) Outlets - 1 concentrate (waste) and 1 permeate (RO Water)

@@nateolszak1078 RO filte is shaped like a bag. The water diffuses into the bag. thereby It has 2 outputs. If the water did diffuse out of the bag, it would be a 1 output filter.

Actually that's not good compared to ro manufacture specifications. You should be closer to 3 to maybe 7 tds. So unless your that range you may not be. It also depends on pretreatment and how hard you run your ro. I also mention that in the video.

Could be pre treatment

It works and we have removed thousands of membranes out. When your dealing with 6 long or 7 long housings and have 20+ housings to do it makes life alot easier.

Good Evening, there could be multiple reasons. Everything from mechanical, to waiting to long to clean, to no using the right cleaners. I would visually inspect the flow meters and make sure they are operating correctly and valves are functioning properly. Then remove the end caps to identify what kind of scale or bio you might have. We have seen customers scale the membranes to the point where no flow was registering. If this happens then you will need to determine what the cause was or is. Example antiscalant was not working or softener failed. Etc.

Thank you for the feed back - much appreciated.

Depends on membranes, how many, the machine size, the chemicals your using and what your trying to clean. My recommendation is to look at the membrane manufacture data sheet along with the cleaners your using.

@@nateolszak1078 my plant unit have 181 vessels and each vessel have 7 membranes

Due to legal reasons we are not able to identify manufacture.

we personally do not, we typically send to factory.

There are a lot of items that can cause DP and Flow issues. Organic, Bio, Scale, Silt, Temp. You may not necessarily see it when opening up the end cap. You may see it when cleaning the membrane. Using a good cleaner is a good start but also making sure the pre-treatment is proper can help.

@@nateolszak1078 thank you! Antiscalant dosing was verified to be appropriate, but the carbon tanks are not sending a shutdown signal so RO may be running during a backwash. Prefilter looks good however, and usually this gets clogged up when I've seen this issue on other systems

@jonezy6056 Water analysis, including PSA and SDI, may help you identify the issue or at least start narrowing down. Could also run into issues if the RO sits for long periods with out use.

EDI Systems can be services, typical services may include, stack replacement, factory rebuilds, cleaning and sanitizing

Could be the pump but typically you would find that right away. You could check the discharge screen of the pump. If your recovering too high you could be scaling your membranes, Also if you have no pre-treatment or are having issues with your pre-treatment you can loose output. If you have the wrong membranes you may have lower output as well. Depending on water temp.

@@completewater We have a large Carbon cartridge before water incoming.

@@Infidel67 You will need more than that most likely. Here is a blog post we did regarding "What Else Do I need With My RO" complete-water.com/blog/what-else-do-i-need-with-my-ro-system

Hello, So my recommendation is to review the manual of the CEDI / EDI Stack Manufacture. They will have procedures for cleaning the Stacks. Highly recommend following it step by step as you can cause irreversible damage.

Unfortunately there is not a "Upgrade" kit to go to a PLC version. They have actually discontinued the E4 Model and have moved over to the LT4. The RO in this video with the HMI is the upgraded version of the LT4. The basic LT4 is very similar to the E4 RO.

Hi Rick, just based on past experience yes it can. However you need the right piping connections, and equipment. Certain design criteria should be in place for this. I have seen some systems operate this way. (Smaller commercial). I will see what we can do to cover that topic at some time this year.

@@completewater That would be awesome. I am curious if a single 4x40 at 300 PSI, such as a Grundfos feeiding into the vessel, would push water through the membrane and into a pressure bladder tank without a post permeat pump. Your videos are highly educational and are shaping the water industry in a positive manner!

Hello, I am not sure what you mean by 2 stage. Its a 2-2-2 Array but single pass. I am not sure what you also mean by 1000+ ppm water. What is 1000 ppm = to TDS? You may have to get an analysis done to verify what is in the water. We have a free E-Book regarding what you need for your RO System. complete-water.com/blog/5-things-you-should-know-before-buying-your-next-ro-free-quick-read It will work on 1,000 TDS Water but you will want to know what is in your water to make sure you have the right pre-treatment.

Unfortunately that is confidential information. They do not share that with us.

Thank you for the feed back. Some day we will get around to shooting another video with no music

We are working on that video for standard ro system. Written step by step procedures. The link is located in the description.

There can be many reasons why DP is high, It can be water quality, flux ratio, organic fouling, too much waste, membranes installed wrong, water temp, lots of reasons why DP is high. The E4 and LT4 RO Systems do not have pressure gauges between stages so not sure what system you have, or how your running. You can find trouble shooting information on our website that might help you go through some things. complete-water.com/resources/reverse-osmosis-troubleshooting-guide

Level 3 comes high tds Stage 1 = 15 Stage 2= 35 Stage 3= 250 Permit tds = 40

@@robinsonvarghese9119 could be water quality or bad permeate o-ring, or bad innerconnector o-ring, you could be recovering too high.

@@robinsonvarghese9119 I would potentially contact them to see if they can point you in the right direction. Unfortunately we dont have enough data to help you. We do offer field services where our technician can come out and help. If you would like to discuss a field service tech to come out you can email your request to info@complete-water.com

probably fouling

Hello, that depends on the membrane. Every manufacture has a limit as to temps for membranes.

Hi Ignacio it was between 800-900 Microsiemens depending on what wells they are pulling from.

@@completewater Thanks for the reply. I work at Biraden Water Solutions, also a Water Solutions company from Uruguay, and I have a very similar proyect. We are going to generate DI Water (<2 microS/cm) from 1400 microS/cm well water, with microfiltration, RO (PROflex LT4-3) and a cation resin tank and anion resin tank. We are currently waiting the RO to arrives to Uruguay from the States, so can't wait to see the plant in operation!

@@ignaciogrosso6942 That sounds like a fun project - send me some pictures once its done would like to see it info@complete-water.com

You have something post ro restricting the permeate flow or you have a bad high permeate pressure switch. (2 most likely causes)

@@nateolszak1078 yes sir we have 0.2 micron

Already blocked 0.2 micron because tds high raw water tds 460 .permit tds 320

Sir I think some these particles going inside. So is there any chance sir

@@robinsonvarghese9119 you might have to replace membranes, clean or check seals/orings. Typically membranes remove 97-99% of the incoming TDS. It sounds like you have a problem there.
