Re: [Amel Yacht Owners] Water Maker Discussion with Rod Borham

Eric Freedman

I too believe I have been overdoing my pickling of the watermaker.
I pickle it for the summer when I am in harbor in new york , and every month
when I leave the boat in the Carib.
What is the correct mixture of sodium metabisulfite and water?

Thank you for Rod's correct email address. He called me within an
hour of my email to him. We had a long discussion on a host of
topics related to the Dessalator water maker, FilmTec membranes,
water maker care and feeding, design philosophy etc. I am preparing
a summary of that discussion that I will post here. He is also going
to prepare a post for this site along with the specifications for the
o-rings used on the membrane end caps and detailed concentration
specifications for the Sodium Metabisulfite pickling solution.

My bottom line is that I will be installing a continuous EC
(Electrical Conductivity) monitor with alarm capability in my
system. I am considering the Omega CDCN201 Mini Panel Mount
Conductivity and TDS Controller with Alarm Modes. You can see it at or just google up
CDCN201. It is available in 12 volt DC or 220 volt AC 50-60 Hertz.

Steve, your understanding as summarized from Rod is basically what I
heard also. More to follow,
