Water Chemistry and Treatment
Jun 03 2012 06:50 PM |
Chris Haslego
in Utilities
Water is a natural solvent. Rain water is acidic due to carbon dioxide picked up in the atmosphere. Water and CO2 make carbonic acid (acid rain). Water hardness is primarily calcium and magnesium. Calcium is limestone - common throughout Midwest. Acid water dissolves limestone, iron, and other minerals in soil.

Deaerators for Boilers
May 22 2012 09:54 AM |
Chris Haslego
in Utilities
Removing dissolved oxygen from boiler feed water is absolutely necessary to protect your boiler equipment from severe corrosion. But the make-up water necessary in any boiler system inevitably contains dissolved oxygen. Oxygen can sometimes enter condensate systems as well. A good deaerator is essential to trouble-free boiler operation.

Wine and Wine Making
Aug 02 2010 12:57 PM |
Chris Haslego
in Other Topics
Wine is fermented grape juice. Wine can be made from grapes, fruits, berries etc. Most wine, though , is made from grapes. And no matter what the wine is made from, there must be fermentation, that is, that sugar be transformed into alcohol. If the amount of alcohol is relatively low, the result is wine. If it is high, the result is a "distilled liquor," something like gin or vodka.
