Hello,

Does anyone know if the frost slows the process down as i am still purifying but it seems very slow of late.   

[brightnclean]

The answer is yes.

RO output slows down as water temperature drops. It stopss completely if u let ur RO unit freeze up    Ohh and if it frezes up you will very likely ruin ur RO membranes.

what about if i am purifying right the way through the cold weather and it doesnt get a chance to freeze will it be ok then.

thanks in advance

I'm still running my purified water through my solar water panels, even though I haven't seen the sun for a few weeks now. I just can't be bothered to disconnect it all as it's too cold evenings

My water production is way down because of the cold.

it was -2.2 when I woke up at 7 this morning and I have just been out and clean one of my own windows and the window ledges froze straight away and as for water production....that is way down....

Water temps play a major roll for the following reason. The temp either increases or decreases the viscosity of water. Colder feedwater has a higher viscosity (thicker water), which slows down production rates, while warmer water has a lower viscosity (thinner water), which increases production rates.

as from tonight i will be putting my little electric blow heater in the van if it gets any colder the water will start freezing. when i am using it i leave the van running all day whilst im out with the doors shut and the heater on full this keeps the engine cold and the van really hot. i aint had no problems yet though i have been looking for a solution to heating my water.

One good this the hihger viscosity means that the RO should produce better quality water i.e. lower TDS.

was thinking the same thing there 

[Davew]

how can that be? surely the microscopic holes in the membranes filter particles out and let water through?

yes under pressure if I am right the thicker the water the better the result.

I could well have got it totally wrong but I dont think I have.

I would have thought you would just produce more waste if the flow was restricted.

Bit of bumph from R.O.Man - "The water temperature is one of the key factors in the performance of the ro membrane element. The higher the temperature the more product flow and vice versa. All ro membranes and systems are rated at 77 degrees Farenheit (25 Centegrade)"
