Air Scrubbing

It's not just wildlife and mudboggers.
Germs also arrive in dust that lands on a water reservoir's surface.

"An annual amount of 21,000 mg dust and 1680 billion germs pass into a 500 m³ water reservoir," states The Huber Report of Water Management in a report referring to processes in Germany, Austria and Switzerland.

So it's not just wildlife and mudboggers peeing in the Aberdeen Plateau's lakes and streams, the source waters for the Duteau Creek Water Treatment Plant.

Even once the water is potable--safe for use by domestic customers--disinfection by-products have accumulated, some to decidedly unsafe levels such as in Duteau Creek's water.
They're nasty ones too, like Trihalomethanes and Haloacetic Acids among others.

So air scrubbing and ultraviolet are being proposed as a pilot project for Duteau, recommended by Stantec Consulting, as follows:

1.  Adding UV disinfection downstream of the Dissolved Air Floatation process and prior to the chlorination at storage reservoir; 
2. Aeration/air stripping of chloroform and other THMs at the reservoir.


The horrendous smell of chlorine disinfection is familiar to everyone on the DCWTP system.

We let Kia's water stand, and hopefully some of the chlorine smell will dissipate, if not the actual chlorine byproduct itself.

Look at what air scrubbing technique the Beverly Hills Small Animal Hospital uses:

"I'd like that air scrubber in my bucket," implores Kia.

Might not need it if the pilot project at Duteau works...
