Re: Excessive usage of water maker membranes
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. Chuck Joy 388

Re: Excessive usage of water maker membranes
When you Do you have to take marina water make sure that you fill trip with the carbon filter to remove all the coring then it will not adversely affect your membranes

Paul;
Which water maker do you have? We have the 150 L/HR A/C only unit. I was told that the system can be run at high green pressure setting, 24x7x365 without any issues. We have not had any issues with our HP pump, so far.

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.

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.

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.

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. Chuck Joy 388 Le Marin, Martinique

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

Re: Excessive usage of water maker membranes
Miles,
So good to hear from you and hope you are doing well.
Thanks for the info on the chlorine test strips. This is an avenue to pursue. We do see lower ppms when we run the water-maker for longer periods and more frequently. But sometimes, like now it doesn’t seem to want to go down and we are in very clean water.
We use a charcoal filter to filter shore water as it goes into the tank. And, I have a double charcoal filter set up for the fresh water rinse. I will check this with some strips.
With best regards,
Mark

Hi Mark, I once ruined a set of membranes by putting chlorinated dock water in the boat and then back flushing. Since then any shore water that goes into the boat first goes through a “whole house” filter that removes chlorine. To check this, I have test stripes that measure the amount of chlorine in water. The test kit is sold in tropical fish stores. My filters are over 10 years old. I have been told that the more the filters are used, the longer they will last. When I don’t use the water maker much, the TDS goes up toward 300. When I use the water maker for my total supply off-shore or in a very clean harbor, the TDS goes back down toward 200. I agree with the comments. I also run the water without pressure for several minutes when I turn it on to get all the fresh water from the back flushing out. I agree with Alan that the pressure with fresh water could be damaging. Regards, Miles s/y Ladybug, sm216, locked down in Le Marin, Martinique

We do not have a pre-pump. I was unaware of the air issue. For the most part I do not see air in the system (via the float gauge). Once and a while there is air during the start up if the sea-chest filter is not all the way full. But, this is not the norm.

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.

Re: Excessive usage of water maker membranes
Mark & Debbie Mueller
As it has been said earlier in this post hydrocarbons (oil, fuel, etc.), chlorine, and over pressure are by far the biggest killers of RO membranes. Operationally, never exceeding the rated capacity of the water maker based on the flowmeter and never exceeding the maximum pressure as shown on the gauge is the rule. If in a brackish water situation maximum flow will be achieved at far lower pressures than what would normally be seen in the “green” pressure zone i.e. it takes less pressure to make RO water when there is less salt in the feed water. The way you described the operation of your water maker seems to meet all the manufacturer’s recommendations; you might look to an over pressure condition. According to Dow a major manufacturer of the membranes the nominal operating pressure is 800 psig (55 bar). If you could get a pressure gauge that shows actual pressure & connect it to your system you could verify that your Dessalator gauge is reading accurately and not showing a lower than normal pressure reading causing you to apply a higher than recommended pressure causing damage to the membranes. -- Mark Mueller Brass Ring A54

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.
