Re: Clack WS1 Water Softener Setup?
edells wrote:It is asking me to 'enter the ion exchange capacity in grains of hardness as calcium carbonate'. What is this and how does one figure what to enter? The default is 24 x1000.
Also, the next question is to 'enter the pounds of salt per regeneration'. How do you figure that?
The exchange capacity in grains depends on the amount of salt used to regenerate the specific volume of resin.
A 32k softener has 1 cubic foot of resin.
With 1 cu ft of resin... (the following numbers are not absolute but generally work)
regen salt @ 6 lbs = 21,000 grains or 21x1000 in your programming
regen salt @ 9 lbs = 26,000 grains or 26x1000 in your programming
regen salt @ 11 lbs = 29,000 grains or 29x1000 in your programming
regen salt @ 15 lbs = 31,000 grains or 31x1000 in your programming
So, if your calculations call for line #2 you enter
exchange capacity in grains 26(x1000) and
regeneration salt 9 (lbs) in the two setting you questioned.
If your calculations call for line #4 you enter
exchange capacity in grains 31(x1000) and
regeneration salt 15 (lbs) in the two setting you questioned.
At different salt doses the salt efficiency changes so you divide the grains of exchange capacity by the pounds of regeneration salt to figure that.
Salt efficiency of line...
#1 = 3500 grains of hardness removed / pound of salt
#2 = 2888 grains of hardness removed / pound of salt
#3 = 2636 grains of hardness removed / pound of salt
#4 = 2066 grains of hardness removed / pound of salt
The most efficient use of salt gives the lowest exchange capacity for that 1 cubic foot of resin.
