Title: Purifying water
Post by: James pryer on May 18, 2019, 11:08:00 am: Hi all,

Am thinking of starting a little add on for my roof cleaning business. Wanted to get into conservatory and green house cleaning.

Wanting to use a water fed pole with purified water.

Will the 3 Stage 75 Gallon Per Day Reverse Osmosis System do the job for me? I’m not fussed about the water it produces a day. Just the fact will it be pure enough to clean windows? As I’ve seen you can get 5 stage filter and was wondering if 3 stage Will still produce same purified water...

Many thanks,
James

Conny roofs come up great with detergent or tfr etc. applied and washed with mains tap, final rinse with pure. If you were using it loads by all means then buy an ro, tank, pump , controller, reel etc. but why not test the water first ? pun intended :D

I use a 4040 membrane with two pre filters and di, 4 stage ?
I dont really know about the smaller systems and what a 3 stage consists of ??? filter, membrane, di ?
Remember 75gpd is probably US gallons and optimum conditions that nobody will ever come close to. yes it will purify water but so slowly you really wouldn't want to bother with it. Its the sort of thing aquarium hobbyists use.

filters just make the membranes last longer and if you dont need loads of water fast 1 membrane is about £30

That's spot on for greenhouses.
Remember to do the insides first but don't sit on a cactus.
