I've been trundling through the water maker deal on the boat and I've heard some details about making water that make me think the unit we have is under powered.
One company says you need about a full horsepower of electric motor to make 10 gph of water. But at what tds should this occur at?
What level of tds are you getting from your desalinator and where are you located? We are currently getting about 500 and I am thinking the membranes are shot already and the unit is under two years old.
Even on a bench in their lab they were not able to get our membranes below 250 at 33k tds.
Are my expectations out of line?
Are there better quality membranes out there or can we get better results from one membrane instead of two in series? I'd like to reduce the tds since the second membrane is not contributing to the production rate all that much anyway.
