Water maker product TDS in Eastern Med

I assume the Eastern Med salinity increases during the dry season.

Is my assumption correct about the Med salinity...and, if so, what should I expect for TDS in water maker output? In other words, should output TDS increase with an increase in input salinity?

I am curious as to what your Med experience is. In most places in the world, we have been able to maintain close to or under 200 TDS in product water. We presently find it difficult to get below 300. We have a 160l/hr 230v water maker with 2 each FilmTec Membranes SW30-2540 (3 years old).

Interested in any similar experiences.

Re: Water maker product TDS in Eastern Med

Hi Bill,

I would have thought that the TDS is dependent on the RO unit rather than the input water, but I am no expert.

It is also quite normal for watermaker systems to have a spread of TDS rather than a fixed number, e.g. my supplier told me that between 200 & 300 was normal and anything up to 500 was acceptable although anything above 500 can cause health issues over time.

I haven't really tracked my TDS values this year, so can't specifically say what has happened, but the sea water definitely has higher salinity, it is like swimming in the dead sea, you don't sink!!

Re: Water maker product TDS in Eastern Med

We have a Spectra Ventura 6-8 gal/hr watermaker and my manual says that as long as the salinity is below 750 ppm, it is drinkable. So I haven't given it much thought, but we achieve around 300 here along the coast of Turkey.

Fair winds,

I have a katadyn and the salinity has varied from 250- 450 , depending on temp, battery voltage and water salinity.
