So do you put the membranes in parallel or series. Hint: Seawater has a salinity of about 35,000 ppm. Or 35,000 / 1,000,000 = .035 or 3.5% of seawater is not water. So even after you take out a lot of water from seawater, it still has a lot of water in it.

Osmosis Watermaker - Part 4 [DIRECTORS CUT] A lot of great tips, particularly waxing up a jigsaw when cutting steel, way easier than oils and probably has a higher interval between applications. This video really made me appreciate how great your team is at making videos with good rhythm, lighting, angles, etc. It's really appreciated

By adding the reject pressure gauge you could be alerted to a plug in the reject system.

@philipwilson867 4 года назад

I still don’t understand how you think you can get away with placing high pressure water stuff right next to your power inverters. Old saying shi@&#% happens

@FrozenHaxor 4 года назад

@@Diggnuts Any small leak on the high pressure side will create a water jet that could ruin the inverters in seconds. And it's very salty water as well. Shielding of the electronic parts is a must here.

If you are worried about the TDS sensors spinning, a compression fitting tee will fit that plastic tubing and not allow your sensor to spin. Not sure if the sensor will fit in a compression fitting, though.

put magnet inside a ziploc bag. you can invert the bag to pull the filings off the magnet and it leaves the filings inside the bag.

I just love the way you just do stuff Doug. You analyze it, make a decision on what has to happen, and then you just do it. Sometimes I overthink things and want to get it perfect before I even turn on the grinder or the welder or whatever. You are inspiring to me!

@gs032009 4 года назад

Great job, Doug. Will you consider adding brass engraved tags attached to the main hoses, valves and switches? SO everyone knows what they are opening or shutting? Will you shield the main electronics- inverters and switchboxes, etc - near the reverse osmosis, with acrylic ? Otherwise they will get sprayed by seawater or accumulate damp which oxidizes the contacts!?

@SVSeeker 4 года назад

No. If you can't tell what it does by looking at it then you got no business working it. And more shielding that what it already has.

@gs032009 3 года назад

@@SVSeeker Allright. That's fair...however... What about if it's dark and no one can see clearly which is which? What about if another operator who is not familiar with the system is on duty and he has to make split-second decisions?

Do you think it would be a good idea to cover your inverters from any possible water leaks eather from the window or the water maker.

heat plastics with a shrink tube blower, not to the point of discoloration, and the surface tension will be reduced and glues will hold much better. Especially UHMW,

If the fitting is facing the wrong way, unscrew and start thread from different position.

Doug, not picking nits but if thr jugs are from veggy oil containers they only hold about 4.7 gals. Not sure that makes much diff. Veggy oil is sold by the pound and jugs that look similar to those weigh in at 35 pounds of oil. Learned all that trivia making bio diesel. Eric

@dougmarder 4 года назад

Do you still have a problem with your overflow/backwash tank implementation? The overflow first fills the left (A) tank, then starts filling the right (B) tank. In this video you say that you will draw backwash solution from A. In your installation I do not see how overflow will move from B back into A. Eventually, tank B will fill to the top, and tank A will already be filled. Did I miss something?

There is a separate suction line and valve for each tank.
