[greebly]

I am looking for equipment that is capable of quickly evaporating large volumes of waste water that contains some HCl and HNO3 (say 200 litres per day or 2) down to a concentrate or dry salt.
I have scrubbers that can take care of the acid fumes.
I have been considering rotary evaporation, but have found that the quotes that I have received for this type of equipment are too high.
Can anyone tell me if rotary evaporation is the best way to go for this type of evaporating and where I might be able to aquire some at a reasonable price.

Such a construction maybe?

you'd probably have to build it by yourself.
