Are you testing the tds before your di or after ?

[luther1]

Easy ian. Its the way the system is set up. If my ro ever does go high the 2 di vessels will clean the water in time for A me to order and B the delivery and possibly delays.

My line of filters consists in this order. .tap. pre filter. Carbon pre filter. Ro. Di 11lt..di 27lt.tank.000 every time.i make 750lts of water every day.

A minimum of 24 hrs flushing is required to reduce the TOC concentration to below 50ppb,assuming zero TOC in the feed water. This is more applicable for water to be used for drinking or food applications and on initial start up of production,not for window cleaning and not during its life span,whereas acid cleaning is required. For someone who worked in the membrane industry,don't you think your advice to 'try' a new membrane is incorrect?

[Goldoak cleaning specialists]

No its sound advice.

If flushing for 2 days doesn't work then yes new membrane if he wants readings under 20 odd or whatever he said. Also he mentioned depending on what mood its in. Ro membranes are very delicate and depending on temperature and last water pass can have a dramatic effect on the membrane. If its up and down all the time only parts of the membrane are working to remove impurities. Flushing will free up more of the membrane to produce pure water.

As for your Google search..lol.. drinking water has a different filter system and could also work for window cleaning as it passes off at under 40ppm.pipes and other flow systems take it back to our tap reading we see when we measure.

Sorry to bust your bubble.

he also said his water pressure isnt very good though.. that also plays a big part of results

Sorry to burst your bubble but a booster pump before ro would help considerably,before the option of a new ro. Have you ever cleaned an ro?

[Goldoak cleaning specialists]

Booster pumps simply prolong the life as particles are less chance of getting stuck in the membrane.  No use when they are gone or not producing low ppm. The only way is flushing as the water flows different in the membrane.

You are the weakest link...goodbye.

So,you've never cleaned an ro then.

[Goldoak cleaning specialists]

Could you elaborate on that please.

I believe its a trick question.

Come on now Ann. Play fair

How is it a trick question?

Have you ever cleaned an ro membrane?

Surely working in the ro industry 10 years ago for 18 months you would know that they can be cleaned?

[Goldoak cleaning specialists]

Dnt get ahead of yourself sunshine.  Ro membranes CANNOT be cleaned suitable for window cleaning.  Once spent the cartridge would have to be recycled. So to answer your question. No I have not cleaned an ro.

Seems to me  you didn't like getting put in your place earlier.
Never mind.  Next time you try to be smart pick someone else.

Ii haven't picked on anyone,I was asking a simple question. You gave the poor advice to get a new membrane and I was giving far cheaper and practical options. I suggest you google a bit more and find that membranes can be cleaned and also can you post up a link to back up your claim of 48 hours flushing to regenerate a membrane please.

[dave0123]

this is an interesting post.. if you have worked in the RO industry you weren't sure about this post you said " apparently"  someone who claims to know what there talking about surely would no the answer lol?

Luther1 you need to reply without the words ffs in your reply to gain any respect. Ie your original repost.

Unfortunately for you you have proven to at least myself that I now have no need to reply to or comment on any of your future posts.

And just for the record I dnt Google answers unlike some. Coff coff. I worked on the real things which I can clearly see has ruffled your feathers.  You did ask a simple question no one is denying that but like I said bad posts and bad attitude in posts gets you no where with me.

The simple answer to this post is. Get a new membrane and flush every week for optimum performance and life span.  .

When you worked in the ro factory,were you the tea lady?

Hi. That is true. I can see how that could look.  Please trust me though I have no reason to lie.

Why is your RO filter only lasting a year? i bought mine before 2008 and its still working strong its just finished producing a 1000 litres for me.

[dave0123]

anyway the orginal poster has stated he has quite low pressure? so it doesnt matter if you buy a new membrane or not..he its low pressure so its not going to bring it down as low as you are thinking. and BELIVE ME I KNOW because i have a pressure of a dismal 13 psi from my tap!

[CleanClear]

I wasn't aware you could clean an RO other than a flush, well tell a little lie i have popped the membrane out and wiped over the exterior of it and give the housing a rinse out. Is that the same or can you clean it another way ?

You can buy a proper membrane cleaning acid/solution

A booster pump also lowers the tds and the amount of waste water,  I know this from practical experience within the last week .
