Want to fine tune my process. What is the most cost efficient way to R.O my water?
Take your own jugs to a store (I go to Walmart) and refill them. Don't buy new ones each time off the shelf. Refills are .39 cents a gallon for me.
Or purchase an RO system for your home. Since I keep large saltwater aquariums, I already have one. The only difference is I skip the "d-ionization" step for beer water, since I do still want some light levels of metals in the water. Check out bulkreefsupply.com for a filter, they can be had for under $100

Store bought is probably the easiest, I happen to have a 5-stage in house system that I use for my brewing water. If you brew 5 gallon batches every other week for a year you would spend about 8 gallons X .40 X 26 batches = $83.20. An RO system is going to cost you about $200 when all is said an done so the breakeven is about 63 batches or 315 gallons of product.
How frequently do you have to replace the membranes/filters/etc. for the RO system? It's probably not that often, but it would still be another variable to compare costs.
I would love to have an RO system, even if it costs a little more, but I have nowhere to put one.

Seriously, though... Do you know that the water is RO? I have a number of places (independent storefronts) near me that sell different waters, and I've been buying the distilled (as opposed to the RO). I get it for about the same cost...
I still plan on sending it out to Ward Labs for testing, to ensure that it is what they say it is.
I'll bet I blew thru 10 gallons of water for every gallon I put in the tank. Now, where I live, the cost of water IS going up.. Not only that, the sewer rates are going up. Water usage is closely tied to my sewer rates.
HbgBill said:Yep.. you could save the effluent and put it on the lawn/trees, etc.. but, that's a pain.. It would get old for me in an NewYork second. No matter how you cut it.. whether you buy it at the store or make it at home.. there is a lot of waste. For me, it's lower water sewer bills.. and I don't have to maintain an RO system.
I have no idea what conditions/costs are in Ontario.. but, where I live, water isn't exactly scarce.. but... I bought an RO system for my RV when traveling in Mexico.. Probably not quite as efficient as a house system.. but, I'll bet I blew thru 10 gallons of water for every gallon I put in the tank. Now, where I live, the cost of water IS going up.. Not only that, the sewer rates are going up. Water usage is closely tied to my sewer rates.
RO water from the stores coming from the big machines is really pretty cheap.. $0.35-.39/gallon. It has many steps and one of them is ultraviolet light.. kills any bad stuff.. I've had only good success with it.
