Re: Excessive usage of water maker membranes

Craig Briggs
 

Right, Alan - an often misunderstood point. You can indeed use your watermaker in fresh water (or brackish) perfectly safely - but not at the full pressure you use for salt water. Just do not exceed the flow rate of the membrane - slowly bring up the pressure until you get full flow and stop. 
Cheers, Craig

Re: Cleaning the prop

eric freedman
 

I usually use dilute hydrochloric acid on my prop. If comes out quite clean.

Be careful not to inhale the fumes.
Many spots need repeated acid washing until there is nothing left to remove.
On some spots that are large , when the acid stops foaming it is time for
new acid.

I then use fine emery paper and my prop always comes out like new.
I do this every 2 years when I haul to change the prop seals.

My only thought is like others, make certain that there is no chlorine. Obviously, there shouldn’t be if all you do is make RO water. Do you ever put water in the tank from the marina? We often have both RO and shore water, tough to tell how much chlorine, although you can buy test strips. I will sometimes flush with a couple of gallons of RO water drawn from the control panel tap, rather than flush with water from the tank.

 

 

This details some of what can go wrong, including post-mortem pictures. Interestingly, there are several causes for physical damage to the membranes (as opposed to chemical) that might have some bearing on your issue.

Cream Puff has a 24v D60 water-maker. My problem is we seem to be going through membranes at the rate of a pair a year. I have read where others have used the same set of membranes for years and still get drinkable water. This is not the case with us. We are in our 5th year of full time cruising and are now on our 6th set of membranes.

 

When I last change membranes in Colombia, this was about March 2019. Our current membranes are just over a year old. The PPMs are starting to creep up a bit now and we have gone from the 300 range to the 500 range. We notice a change in drinking quality over 600 PPMs. This is when we usually change the membranes.

 

We run the water-maker at least once a week when in a marina, flush it with the fresh water rinse. I have a double charcoal filter set up for the tank rinse. When on anchor it is run just about every day. I am careful to watch the pressure and water making float gauge. I normally set it at 55 liters per hour and this put the pressure in lower side of the green range.

 

Any ideas why our membranes are not lasting or why our PPMs creep up?

Re: Excessive usage of water maker membranes

Alan Leslie
 

To be clear
Fresh water on its own will only kill membranes if the membranes are exposed to either high pressure fresh water or fresh water with chlorine in it.
Unchlorinated low pressure water (which is what you use when flushing with your product water) won't kill your membranes on it's own.

Hi;

 

When we first purchased Kokomo, I had detailed discussions with Martin, the head tech at Dessalator, about the environments that the water maker could be used and best practices. The following was my takeaway:

 

  1. The water maker can be run safely in most waters. This includes harbors, marinas and even water that is not clear. I was told that the main detriment would be more frequent changes to the pre-filters.
  2. The water maker can be, and should be, run in the high end of the green zone. This will lead to more water production, without any downsides.
  3. Performing an auto fresh water flush after every usage is unnecessary and wastes about 20 liters of fresh water. As long as the water maker in run at least every week, a fresh water flush is unnecessary. We simply stop making water by shutting down the switch and then backing out the pressure valve.
  4. Utilize the powder provided by Dessalator to prep the membranes for the winter season.

 

We have done the above for 5 seasons of about 5 months each. The pre-filters typically last a whole season. We never put any water in the tank other than from the water maker. The water quality is always below 250 PPM. When we purchased Kokomo, the water maker had only 60 hours on it. So, I’m fairly sure that our membranes are original from 2008 and therefore 12 years old. The water maker now has around 550 hours. I was told that after 500 hours, the quality will probably start to drop. Our usage has solely been in the Med.

Hi Colin,

 

Yes, I re-read that part and it is a little confusing how I wrote it. In marina, we do a fresh water flush aobut once a week. We do not run the water maker in that environment.

 

Thanks for the insight, I guess I need to be more fussy about where we run it. I thought the pre-filter would help a lot. I guess not.

Hi Mark

 

We had the 100L/Hr Duo on Island Pearl II and went around the work in three years with a new 2016 set of membranes. Those membranes were still perfect at the end of our trip doing a full 100L/Hr easily on the a/c current but slightly down to 75L/hr on the DC current motor. 

 

We were absolutely fussy about the cleanliness of ocean water before running it and were sometimes scoffed at by others eg in Rodrigues (Indian Ocean) for lifting anchor, risking losing our good spot to go out to sea every four-five days to make water whilst other cruiser friends simply made water inside the large seawater harbour where we felt the water was not up to scratch. Also, we never took the boat out onto the hard for a season, even though we had planned to do this in the Caribbean in 2019.

 

If you are careful like this, which I suspect you are, then there must be something else at play with your system and I look forward to hearing about that from other more experienced cruisers here.

 

Also, since we have communicated often and I admire your equally careful approach to looking after Creampuff, I highly suspect that when you refer to "running your watermaker at least once per week in marina's", that you actually meant "doing a freshwater flush cycle" in the marina from your tank as per the manual requirements.... rather than actually making water from the extremely dirty marina seawater which would totally explain everything about your problems, but which I am equally sure you would never have done.

Hi Mark.

I am very careful about where i run my watermaker. Never in a marina and it has to be an exeptionaly clean harbour before I will run it there. Also I am paranoid about even traces of chlorine. It is many years since I allowed any chlorinated water into my tank. However you living full time aboard would suggest a lot of use. Like a car,  its not the time that wears them out but the milage.

Re: Excessive usage of water maker membranes

Chuck_Kim_Joy
 

Yes. I did not state in my previous post that I double filter 5 micron into the tank. I try and take all precautions but I too have high ppm after one year of new membranes. Faulty membranes maybe? A desalator dealer in Le Marin just said 500 ppm was fine and not to worry til I got to 1000! Goodness. I put dock water in today and it measures 150 ppm through the filters. Tasty. But I know that's not chlorine. Anyway probably new membranes in November and I'll cross my fingers. Good discussion.

Hi Colin,

 

Yes, I re-read that part and it is a little confusing how I wrote it. In marina, we do a fresh water flush aobut once a week. We do not run the water maker in that environment.

 

Thanks for the insight, I guess I need to be more fussy about where we run it. I thought the pre-filter would help a lot. I guess not.

 

 

With best regards,

Hi Mark

 

We had the 100L/Hr Duo on Island Pearl II and went around the work in three years with a new 2016 set of membranes. Those membranes were still perfect at the end of our trip doing a full 100L/Hr easily on the a/c current but slightly down to 75L/hr on the DC current motor. 

 

We were absolutely fussy about the cleanliness of ocean water before running it and were sometimes scoffed at by others eg in Rodrigues (Indian Ocean) for lifting anchor, risking losing our good spot to go out to sea every four-five days to make water whilst other cruiser friends simply made water inside the large seawater harbour where we felt the water was not up to scratch. Also, we never took the boat out onto the hard for a season, even though we had planned to do this in the Caribbean in 2019.

 

If you are careful like this, which I suspect you are, then there must be something else at play with your system and I look forward to hearing about that from other more experienced cruisers here.

 

Also, since we have communicated often and I admire your equally careful approach to looking after Creampuff, I highly suspect that when you refer to "running your watermaker at least once per week in marina's", that you actually meant "doing a freshwater flush cycle" in the marina from your tank as per the manual requirements.... rather than actually making water from the extremely dirty marina seawater which would totally explain everything about your problems, but which I am equally sure you would never have done.

Cream Puff has a 24v D60 water-maker. My problem is we seem to be going through membranes at the rate of a pair a year. I have read where others have used the same set of membranes for years and still get drinkable water. This is not the case with us. We are in our 5th year of full time cruising and are now on our 6th set of membranes.

 

When I last change membranes in Colombia, this was about March 2019. Our current membranes are just over a year old. The PPMs are starting to creep up a bit now and we have gone from the 300 range to the 500 range. We notice a change in drinking quality over 600 PPMs. This is when we usually change the membranes.

 

We run the water-maker at least once a week when in a marina, flush it with the fresh water rinse. I have a double charcoal filter set up for the tank rinse. When on anchor it is run just about every day. I am careful to watch the pressure and water making float gauge. I normally set it at 55 liters per hour and this put the pressure in lower side of the green range.

 

Any ideas why our membranes are not lasting or why our PPMs creep up?

Re: Excessive usage of water maker membranes

There are times when you must take marina water and thus can only flush with marina water. I find it hard to believe that the makers of the membranes would not have considered this possibility in the boating world. Then again it might be pure science and I must make water in dirty marinas and harbors come what may. I have a good supply of pre filters.

I envision us meeting for a total of 30 minutes to discuss two issues. If there is interest we could schedule subsequent ZOOM meetings.

Is there any member of our group that is experienced with hosting a ZOOM meeting and willing to volunteer to moderate the meeting?

Any other thoughts?

Mohammad,

 

It was at a time when the HP pump was on its way out. I ended up replacing it. I have since run with the pressure on the orange/green border and it has been fine and still made 100+ litres/hour.

Hi;

 

When we first purchased Kokomo, I had detailed discussions with Martin, the head tech at Dessalator, about the environments that the water maker could be used and best practices. The following was my takeaway:

 

  1. The water maker can be run safely in most waters. This includes harbors, marinas and even water that is not clear. I was told that the main detriment would be more frequent changes to the pre-filters.
  2. The water maker can be, and should be, run in the high end of the green zone. This will lead to more water production, without any downsides.
  3. Performing an auto fresh water flush after every usage is unnecessary and wastes about 20 liters of fresh water. As long as the water maker in run at least every week, a fresh water flush is unnecessary. We simply stop making water by shutting down the switch and then backing out the pressure valve.
  4. Utilize the powder provided by Dessalator to prep the membranes for the winter season.

 

We have done the above for 5 seasons of about 5 months each. The pre-filters typically last a whole season. We never put any water in the tank other than from the water maker. The water quality is always below 250 PPM. When we purchased Kokomo, the water maker had only 60 hours on it. So, I’m fairly sure that our membranes are original from 2008 and therefore 12 years old. The water maker now has around 550 hours. I was told that after 500 hours, the quality will probably start to drop. Our usage has solely been in the Med.

 

Happy Sailing;

Re: Excessive usage of water maker membranes

Mohammad Shirloo
 

Hi Mark;

 

Some potential causes that maybe worth looking at and a couple of questions;

 

  1. How many hours do you put on your membranes before they need replacing?
  2. Any potential source of chlorine in your main tank that is used for back flushing?
  3. Any potential for freshwater presence in the membranes when you start increasing the pressure in the membranes? Think about the process that you go through to make water and see if there is a possibility that some of the fresh water that was used to flush the system, could still be remaining.
  4. Do you have a low pressure pump feeding the high pressure pump, or is it just the water pressure from the thru hull?
  5. Are you cruising fulltime or do you store the boat certain periods of the year? If you leave the boat for more than a couple of weeks, how do you treat the membranes for that period?

 

We have a 150l/hr AC water maker, so our experience may be very different than yours. I would suggest a call to Martin. He is responsive and extremely knowledgeable and helpful. He has been able to walk us through several issues with our water maker and his solutions and suggestions have usually been spot on. Let me know if you need his contact info.

 

Happy Sailing;
