The preparation of distilled water

The multitude of types that are made indicates that the ideal still, from the aspect of economy, has not y et been realized. To achieve better utilization of heat internal 

Water still Purator , made of quartz glass, with throughput of 2 1/h of distilled water 

Automatic water distillation apparatus made of Duran 50 Throughput 10 to 70 1/h 

An electrically heated water still made of Duran 50 was developed by Schott Gen. of Mainz (Fig. 148). The various designs have throughputs from 10 to 701/h of distilled water with a conductivity 0.5 fjS when they are fed with fuUy desalted 

Apparatus for the simultaneous production of distilled and doubly distilled water (Kullmann)
