Yes, Kent, that's what was pointed out - OK in fresh water if you don't exceed rated fresh water flow, not that you need to watch the high pressure.  Just that it will be much lower than with salt water.

That being said, as Bill pointed out, there may still be an issue with bacteria from depleted pickling chems.

I don’t think it’s the pressure you need to watch, Pat.  It’s the RO water flow.  Does yours have the glass tube with float that indicates how much water you are making?  Keep that below the rated volume your unit produces.

Craig , I will watch the video, I would really like to run it now before I leave, so that I can replace/repair here before departure. The membranes have only been used for six months , then pickled for 31/2 years . I don't know what that does to them , it seems if you ran them for awhile they would clean themselves ,who knows ,I don't. So you are saying as long as I don't turn the pressure up beyond the green zone , it would be OK .See ya in ST. Michaels.

Hi Pat,

You definitely can run your watermaker in fresh water without ruining the membrane(s). The only caveat is that you must not exceed your fresh water output rating.  

Start your unit up with, as Alan says, the pressure knob fully closed (which you normally do). Then bring the pressure up slowly and monitor the fresh water output flow. In sea water, where you might need 800 psi to get your rated output (mine is 20 gph), in brackish it's maybe 400 or so and only 200ish in fresh water.

For a good video on this by Rich Boren, who owns the CruiseRO company, check out http://blog.cruiserowaterandpower.com/can-i-run-a-marine-water-maker-in-fresh-or-brackish-water/
If the link on the last line gets garbled by yahoo, it is http colon slash slash blog dot cruiserowaterandpower dot com slash can-i-run-a-marine-water-maker-in-fresh-or-brackish-water slash

I used to do this all the time on Sangaris, so I know it works.

Cheers, Craig SN68

Alan, I am concerned about that , leaving them pickled so long and they were new four years ago. So it sounds like there is no way to fully test the system until I get to salt water. If I could find a way to make up some salt water and recirculate it ,that would work. I would like to put it through a stress test prior to heading for the Caribbean.

Hi Pat,

ATF 90 - Automatic Transmission Fluid SAE 90

You can rinse the membranes with fresh water with the pressure knob fully anti clockwise i.e. no pressure.
If you pressurise the membranes with fresh water you will ruin them - if they are not already ruined from sitting pickled for that length of time.

Maybe it is better to go for 1-2 micron Racor filter instead of the recommended 10 micron in order to filter out as much as possible. Or does the Engine suffer from the reduced flow rate?

It’s good to see Nigel opening the debate about what needs to happen to adress the issues of modern engines in marine environments. It seems to point towards fuel quality. The corollary being inadaquate onboard filtering. 
I wonder what it means for fuel additives and their adequacy for our problems. Naively I would think that any product that dissolves contaminants simply makes them smaller so potentially riskier for high pressure common rail injectors (ie pass through filters but still too big for injectors)? 

Another topic is the established advice that a diesel engine enjoys being run at 80%, and failing that, at least push it hard from time to time. How much of this is still relevant to modern engines with better fuel efficiency (so less residue at low regime I presume) and variable geometry turbos?

Re: [Amel Yacht Owners] Re: Watermaker and transmission fluid

Rudolf Waldispuehl
 

Hi Alan

I know from my former Boat's Watermaker. After using a while it helped the performance a lot by cleaning from time to time with extra cleaning cartridges. 

What I know; Freshwater under pressure destroys the membranes as well as fresh water with chlorine inside. In some marinas you only get this. Thats why I always use carbon filter to fill up tank with drinking water. I'm not filling non drinking-water or somehow contaminated I'm not knowing.

You need freshwater after using to rinse/flush the salt-water out. Reason is that sea water is fouling much faster than fresh water because there is much more organic stuff in it. When you use the Membranes daily there would be no real need for flushing all time, because time until re-use will not allow for much growth inside. 

Btw: You can manually flush the system as long as you like by turning the 3way valve in the engine room to fresh water supply.

In the Dessalator Duo 60 manual  it says:

Fresh water should be always used with no pressure when going through the system

freshwater from sea water (also with the pressure dial all the way anti clockwise).
When running the watermaker with the dial all the way anti clockwise, it will shut it self
down automatically after 1 minute. Only then, the watermaker is ready for use.


I have the Filmtec Membrane Technical Manual and I can find no discussion of this at all anywhere.

In fact a number of systems are illustrated that
1. Treat Brackish water
2. RO the RO water (double RO) to make ultrapure water.

So I don;t know where this freshwater enemy story comes from......nothing on a Google search.

If it really was a problem I would think Filmtec would warn about it.

When I look in my manual (thanks to others!) there is a whole page of approved fluids, and the only common theme is ATF
So my guess is that any ATF will do, after all we don't subject our transmissions to anything like the stresses that the automotive guys do, mostly we're puddling along at 2000 rpm, no rapid accelerations or decelerations ...?

Thomas,

 

I have the VOLVO D3 110 H version; which I usually run between 1150 and 1300 RPM; burning about 2.5 lph at these rpm’s.

During engine sea trial in June 2018, with 6 people on board, this is what I reported to Bill ROUSE:

 

QUOTE

 

New VOLVO is in; engine sea-trial went perfect for 1 ½ hours in windy & choppy conditions. That’s why we didn’t go out in the lagoon (35knts winds) but stayed in the harbor.

 

Top speed 9.4 but with about 2780 rpm’s. This is 200 rpm below the 3,000 rpms set for the engine.

About 7.3 at 1200 to 1300 rpm’s – this is her sweet spot.

 

 

UNQUOTE

 

This is part of Bill’s reply:

 

QUOTE

 

I would clearly accept the results you had

 

UNQUOTE

 

According to the SYDNEY tech (also services the AUSTRALIAN and NEW ZEALAND NAVY) it is not harmful for the engine to run at these RPM’s. He suggests to vary speed (increase) every 2 hours or so.

Re: [Amel Yacht Owners] Re: Long block failure on a Volvo D3-110 Amel 54-152

Reudi,

You should have two filters
A Racor primary filter (or 2)  ,mounted on the bulkhead and a secondary filter mounted on the engine.
The primary filter is there to filter out gross contaminants and water...it should be 30 micron or min 20 micron.
the secondary filter on the engine is to remove any fine particulate matter and should be what the engine manufacturer recommends..10 or so micron normally.

The primary filter is there really to protect the secondary filter, and if you use clean fuel you should rarely have to change the secondary filter.

Using a fine 10 or 2 micron filter in the primary will just lead to more filter changes as they will clog up more quickly.

For example Yanmar recommend a 30 micron primary and 10 or 2 micron secondary for their modern common rail engines, 

We have an ordinary old fashioned donk and use 30 micron in the primary and 10 micron in the secondary and always filter the fuel with Mr Funnel when refuelling.

Hi Pat,
I regard the SM helm seat as a great design and a vital safety item. I have a lot of ocean miles behind me and in the vigorous seaways we encounter out there its fixed place stability is a huge safety factor. I would never have a swiveling seat. In big rough seas, oh boy. Likewise, even more so the tube up the sides and across the back. When you are moving around the cockpit in rough conditions it is a fantastic "grab when I'm off balance" hand hold. Moving around the cockpit in a seaway I am using that hand hold all the time. Bad accidents on yachts at sea are often caused by falls.As we age our bones become brittle and our balance less. Henri gave us hand holds every where for good reason. Swiveling padded comfort seats are for the marina and harbour set. Not for serious off shore.

Re: [Amel Yacht Owners] Re: Watermaker and transmission fluid

greatketch@...
 

RO membranes are rated for maximum pressure OR maximum flux of product water, whichever is reached first.

If the feed water is nearly fresh, very low feed pressure (maybe lower than 100 PSI, 7 Bar) will result in maximum flow of product water.  Running like this will not damage the membranes.  The "reject rate" of salt removal will be similar, so you will end up with quite pure water.

In the Chesapeake Bay, you will very quickly clog your prefilters, so be ready for that.  It is a rich biological soup.  If your membranes have been pickled for over 3 years, I would recommend cleaning them before pressurizing to remove as much accumulated biofouling as possible so you do not push it deep into the membrane pores.

Hi Bill,

Yes, I assumed he was abbreviating Dextron ATF and that Dextron II was replaced with the more modern formulations of III and then IV.  As you know the ZF manual has an extensive list of which brands of fluid are acceptable....I could find none of them, so just used a name brand, "Dex IV" fluid.  I'm probably fine with that, but if ZF has an updated list, I wanted to check what I used against the new list.  Now on to that dipstick issue...

Re: [Amel Yacht Owners] Re: Watermaker and transmission fluid

I'm now not so sure about this fresh water business.


In the Dessalator Duo 60 manual  it says:

Remember: The biggest enemy of the membranes is fresh water.

Fresh water should be always used with no pressure when going through the system
(pressure dial turned all the way anti clockwise) and the system should always run with no
pressure after a fresh water flush to dump all the fresh water that are in it, before making
freshwater from sea water (also with the pressure dial all the way anti clockwise).
When running the watermaker with the dial all the way anti clockwise, it will shut it self
down automatically after 1 minute. Only then, the watermaker is ready for use.


I have the Filmtec Membrane Technical Manual and I can find no discussion of this at all anywhere.

In fact a number of systems are illustrated that
1. Treat Brackish water
2. RO the RO water (double RO) to make ultrapure water.

So I don;t know where this freshwater enemy story comes from......nothing on a Google search.

If it really was a problem I would think Filmtec would warn about it.

I don’t think it’s the pressure you need to watch, Pat.  It’s the RO water flow.  Does yours have the glass tube with float that indicates how much water you are making?  Keep that below the rated volume your unit produces.

Craig , I will watch the video, I would really like to run it now before I leave, so that I can replace/repair here before departure. The membranes have only been used for six months , then pickled for 31/2 years . I don't know what that does to them , it seems if you ran them for awhile they would clean themselves ,who knows ,I don't. So you are saying as long as I don't turn the pressure up beyond the green zone , it would be OK .See ya in ST. Michaels.

Thanks,

Hi Pat,

You definitely can run your watermaker in fresh water without ruining the membrane(s). The only caveat is that you must not exceed your fresh water output rating.  

Start your unit up with, as Alan says, the pressure knob fully closed (which you normally do). Then bring the pressure up slowly and monitor the fresh water output flow. In sea water, where you might need 800 psi to get your rated output (mine is 20 gph), in brackish it's maybe 400 or so and only 200ish in fresh water.

For a good video on this by Rich Boren, who owns the CruiseRO company, check out http://blog.cruiserowaterandpower.com/can-i-run-a-marine-water-maker-in-fresh-or-brackish-water/
If the link on the last line gets garbled by yahoo, it is http colon slash slash blog dot cruiserowaterandpower dot com slash can-i-run-a-marine-water-maker-in-fresh-or-brackish-water slash

I used to do this all the time on Sangaris, so I know it works.

Alan, I am concerned about that , leaving them pickled so long and they were new four years ago. So it sounds like there is no way to fully test the system until I get to salt water. If I could find a way to make up some salt water and recirculate it ,that would work. I would like to put it through a stress test prior to heading for the Caribbean.
Thanks,

Hi Pat,

ATF 90 - Automatic Transmission Fluid SAE 90

You can rinse the membranes with fresh water with the pressure knob fully anti clockwise i.e. no pressure.
If you pressurise the membranes with fresh water you will ruin them - if they are not already ruined from sitting pickled for that length of time.

Cheers
