Drinking Water Quality

11/23/2011 2:13 AM

hi guys,

i need to know the standards level of drinking water. i received test report about our drinking water, i couldn't understand. please help. is this good to drink

Turbidity 0.56

pH 8.81

conductivity (us/cm) 117.3

total hardness (ppm) 27.0

i have a brief idea about the process, i will say as i know!!

this water is produed by sea water. 1 st it goes to RO-1 (desalination) plant then to RO-2 plant. then it goes various process to make drinking water (lime stone, ion exchange, etc)

In vino veritas; in cervisia carmen; in aqua E. coli (and maybe other nasty stuff). Just stick to the basics!

(There will be some redundancy shortly. Sorry.)

Buy a bottle of any brand of the popular bottled water products and compare your figures against that.

The water is too pure to be used as drinking water. It will taste unpleasant. To achieve palatability, the calcium ion level ideally needs to be >60ppm, which will not be achieved given such a low conductivity (assumed 20degC).

Consider the use of a re-hardening filter downstream of the existing processes, and consider taking the drinking water precursor stream from the stage 1 permeate and not the stage 2.

There is a World Health Organisation quality recommendation for potable water. Any internet search engine will find same.

This article proposing standards for desalinated drinking water might be of interest.
