I
wondered why John had not responded. I checked the email address, and the
one that Ray lists is in error. He has not been feeling well, let me see
if I can get his attention so that you can get the answers.
I can
give some general advise, based on information that John has provided me in the
past. But he is the authority.
It is
probably wise to assume that you will get less than the rated capacity of the
membrane. I usually assume half the rated production. Water
temperature, and water pressure are the major influences in my experience.
I use what is called a permeate pump to improve the production and increase what
is actually put into the tanks. John can give you details, but it
essentially reduces the backpressure on the membrane. I don't know how
much membranes differ for the kinds of units we use. His guidance was to
put the RO system in AFTER the water softener.

You definitely want to contact John Talpa. He is a water-treatment
professional, and an orchid grower to boot.
I bought my RO unit from PremierH20 (25 gpd), and John helped me upgrade it
to 100 gpd at a fraction of the cost of a new system.
I believe his email is [EMAIL PROTECTED]

Subject: [OGD] RO water systems I am looking to upgrade my RO system to a bigger and better system as my orchid collection is growing and I am using and automatic humidification system this winter and both of them are exceeding the capacity of my current system. If you want to respond off line that is good, but I think everyone would appreciate some dialog that was not related to taxonomy or people arguing. I need a system that will give me at least 50 gallons per day and I am thinking of going to 75 to 100 gallons just to give me room to grow. My current 25 gallon per day system was and is good, but is too small. The local dealer I got it from is no longer in business, so I am shopping for a new system. I have well water, so I need a system with a booster pump and a membrane that can take alkaline water. I need high capacity. I have a 40 gallon 40 psi pressure tank on my current system and a 250 gallon storage tank. If any one has a large capacity system they have been happy with I would like to know more about it, where you got it and how it has worked for you. If you have a system you have not been happy with I would like to know about that so I can avoid that company. I have found lots of sources on the net, but I want some comments to help me narrow down the companies before I start calling them. thanks, -- --Tom /------------------------------------------------------------------------------------ | Tom Hillson Orchid Grower Specializing | [EMAIL PROTECTED] In Paphs and Pleurothallids | [EMAIL PROTECTED] | http://www.orchids.iastate.edu ------------------------------------------------------------------------------------- |"There is always room for one more Orchid!!" _______________________________________________ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com |
