Reverse Osmosis Setups

Re: Reverse Osmosis Setups

I just found a useful link on how water softeners work. Provides a few thing to think about when planning your cleaning/plating water supply.

Has anyone thought about adding a DI filter to their RO set up? Kent marine has a few that add on the filters that caswell carries. Information seems to indicate that RO filters (plus pre-filters) remove 94-98% of contaminants while DI filters (plus RO + per-filters) remove 99.9% of contaminants.

Since I added filters to my cleaning and electrocleaning tanks I just top off. I top off tank from rinse1 and top off rinse1 from rinse2 and rinse2 with new water from RO.

Thanks,
I'll try using water from the sprinkler system. The water softener is a bit pricey to keep fed with salt.

I would run it from the lawn water, unless you aren't paying the bill for the upkeep on the water softener. If you aren't, running it from the softened water would be best. Your TFC membrane will last longer with the softened water.

Re: Reverse Osmosis Setups

Just ordered my 35 gallon RO unit from Caswell. Hope it reduces the calcium carbonate precipitate that settles out in my electrocleaning tank

I was getting the plumbing set up this afternoon and was wondering is it better to get my supply water from the utility sink which passes though the building's water softener or should I tap off the lawn watering system which is not run through the softener?

Both are city water.

Thanks

Re: Reverse Osmosis Setups

Thanks,
I was just searching for Kent Marine (I think that is the brand of RO unit you carry) for their float valves at http://www.kentmarine.com/waterfilters/fv.html That should meet my needs.

We'll be adding a 35 GPD unit, and a float valve to our lineup this week.

Re: Reverse Osmosis Setups

I have the unit which will put out about 5gal. in 4hr. and I just keep a eye on it so I don't have to worry about a valve or taking up more room with a bigger bucket.

Does anyone have any pictures of their ro setup?

I was thinking of running caswell's unit http://www.caswellplating.com/kits/ro_unit.html
into a 55 gal plastic barrel.

Adding a spigot near the bottom should be pretty easy. The part I am really wondering about is how to add a float valve (as found in your average wc) to shut off the ro unit where the barrel is full.
