WHO guidelines for water quality
| The standard RSD water treatment degrades those water ingredients affecting safe UV disinfection. Some organic chemical compounds which impact taste and odour are extracted as well. Concentration of other harmless or even desirable ingredients like minerals occuring in natural water will not be changed with the treatment process. The same is with many of the parameters listed below, because in 80 to 90 % of all cases they do not affect water quality. If some toxic compounds comprising arsenic, lead or uranium appear, we have special solutions which can be simply added to your RSD-equipment (click here). |
|
Please check, if there is
some
probabilty of toxic impact of your raw water e.G. by industry,
mining or
agriculture. If in doubt,
contact us.
