water evaporation

On small tanks prefilters tend to be pretty quiet as the sump pumps are not that big and don't create massive flow. I think I've seen some do durso mods on hang on the backs, not sure. Oh yeah, check out the 'weir' style overflow in the DIY forum. Start a new thread and maybe we can figure it out.

 

thanks matt, i'll do some looking into it. this web site is so helpful!!!!!!

 

Speaking of evaporation, how much evaporation can you expect with a 120 gl tank?

Just curious. I had a tremendous water bill and I'm trying to figure out where all it came from.

I have a 75 Gallon with an open top and I usually loose threw evaporation about 1/2 to 3/4 gallon a day ......... John

 

So I guess I could easily be loosing 1 gl per day. So with the ro'di that would be around 4 gls per day. It surely does all add up quickly.

I'm not understanding that :-/.............John

 

Sorry about that John. My understanding is that when using a Ro/Di system that for every gal. of filtered water it takes 4-5 gls to make that one gl. So If my system evaporates one gl per day, then just for top off I am using around 124 gls per month not including my new water I make up. Over the past month I've been making up at least 50 gls per week because of the frequent water changes that I had been doing. I'm backing off to once or twice a month now.

I hope that make a little more sense now?

I never herd that before :-/ were did you read that?

 

It is in my literature for my RO/DI unit....3 - 4 parts waste water to every 1 part pure water.

 

Thankyou Miss Moderator! I guess I need to start up a library. I don't have any of these sites saved so thanks for your link. I probably need to review it myself.

It also depends on the type of unit you are using and if you use a pump with it or not. You can get a permeate pump that will allow your unit to work more efficiently. I'm not sure what the ratio comes out to be when using a pump.

For other questions you can log on to Air Water and Ice (AWI) which is one of our sponsors. E-mail any question you might have to Walter and he is very speedy about getting back with you. I have their Dual Home unit-6 stage and have been very pleased with it.
