Filling a wfp tank

Posted by sham33 (sham33), 17 January 2004
Hi, this might sound a really stupid question to every 1 who uses wfp's but when u fill the tank, do u put the water directly into the tank, fill it up, and purification take place when the water is being drawn through the resin filters when using the pole. Or do u fill the tank up through the resin filters so the water is pure as it enters the tank ready for use?

With a Commercial Reach & Wash System The hose pipe is attached to the fill on the inlet and goes through 4 stages of the hydro powered system into the holding tank at 98% pure, the systems require no electric pumps when filling so are silent running. (so no grief from neighbours when filling overnight)The final stage of purification is done on site as the water is pumped out of the tank through a colour change resin to polish the water to a zero TDS.  
All our Reach & Wash Systems can also be filling on site as you are working, giving you a benefit of running additional poles or working an extended day.

Hi Reuben.

Just out of interest, if the tank holds water at 98% purity, does the tank itself require any maintenance or cleaning over the years? Or is it sealed against outside contamination?

HYDRO POWER?
many people do get confused with jargon and as we all know its Dom's job to keep it real, so here we go;
What is Hydro Power? Some manufacturers lay claim that hydro power is the key to producing pure water efficiently...they may be right, but what is hydro power and how do you know if hydro power is going to be of benefit to you?
 You can work out how much hydro power you have got, or hydro power units (HPU'S) as they are known, quite simply. If you have a pure water machine, simply connect to your water mains supply and turn your tap on, with regulating valve shut.
Your pressure gauge will rise to a stable reading and as a working example, if the gauge shows 60PSI, you have at your disposal 60HPU'S. If you have 90HPU's you have a lot of hydro power, if you have 30HPU's you are unfortunately bereft of hydro power.
 For the fortunate people who always have lots of hydro power, even in droughts, towns mains water pressure as it is commonly known, may be your answer. All pure water machine suppliers manufacture hydro power machines.
For those unfortunate people who have little hydro power, you need to speak to suppliers who can provide enhanced boosted fill capability, or as BRODEX refer to it,
HYDRO POWER PLUS+  (TM)

ok, thx for the answers  Cool

Reuben,
can you tell me what happens to your system when the mains water pressure going in is only 18psi? this person has had the water company round, they say it is above their minimum allowed pressure. but is only getting 3 fills out of one of your 7ltr Mixed bed resin cartridges before he has to buy another one off you at £52.50.

Hi Reuban,

Why would the PSI influence the lifespan of one of your di filters?

PS. Thanks DOM for the helpful post  Wink

Steve,

If you contact us privately then I will be happy to advise you and pass on best practice regarding low pressure issues. When competitors are asking us how we do it then its not our business to tell them. However, there are regulations that must be adhered to, as set out by the local water autorities and therefore there are ways to boost pressure that are in complience and there are others that are not. So customers may ask us, competitors need to do their homework.

regards
Reuben

Thanks Rueban,

I'll be in touch

All Pole Users
Just incase you are in the dark and feel a little left out, BRODEX install pre-treatment plant (BX/DI etc) every week into factories , hospitals etc. so Steve if you'd like to send me a private e-mail, we'll give you the water treatment Industry angle on how to deal with compliance issues.

RO systems do not work well at this low pressure they need at least 30psi to start working if it is less than that the internal seal will not make thus allowing a percentage of rejection water through then this has to be cleaned by the mixed bed resin so the mixed bed dose not last as long.

Aps,

Thanks for info. Really helpful. The water here is pretty soft 68ppm so i'm using di at the moment. I am hoping to have a static system in the near future where I will want to use RO. I'll check any possible future premises for sufficient water pressure.

DOM,

Thanks for the offer. It's not really in my interests to have companies installing their own permanent systems on site. I want them to pay me to do it.  Grin But if issues regarding such ever become a problem I would welcome your advise. Also will be in touch about static system to get your alternative recommendations and prices once I find somewhere suitable.

The definitive answer from APS pure wash.!
BRODEX agree with this answer completely and thanks to Pure wash for "keepin it real.!"

Had to answer my own question in the end!!!  oh well never mined Sad
Posted by Reuben_Reynolds (Reuben_Reynolds), 19 January 2004
Andy,

Clearly we know why low pressure affects RO product water quality. Dealing with the problem by providing a solution that complies with regulations is the issue. Simply placing a pump in-line neither complies nor does it solve the problem. If water pressure is insufficient to serve the RO then it will also be insufficient to supply the pump. The result will be cavitation and contravention of regulations.

regards

Reuben.

Who said anything about pumping directly from the mains this is against regulations having worked in conjuction with a water Specialist for a few years I know how I it works.

Andy,

Good, that's two of us that know how it should be done, it was a different contributor that has a different view.

Cheers

Yawn...!

earlier in this thread you said that your systems require no electric pumps when filling so are silent running so how do you get round this amazing amazing feat?

do you supply additional equipment to get round this problem? gear that is static?

Andy,

With respect, its not our business to advise you in your business.

dont need your advise anyway thanks just never seen any other systems of yours, than mains pressured ones!!!
Funny that!!!

I think you'll find thats..."HYDRO POWER"..! The power of water mains pressure, harnessed....in........ your....erm.... "TAP"....!
