WASTEWATER AERATION

Only a few of these enthusiasts realized that the waters they so highly praised were clear, bright, sparkling, tasteless and odorless when they reached the streams. In the eighteenth century, artificial aeration was directed at making up the oxygen deficiencies of distilled water and of rain water that had been stored up in household cisterns. Toward the end of the eighteenth century and early into the next century, aeration was applied to a few public water supplies carrying decomposed vegetatble or animal matter.
Not until the last half of the nineteenth century did aeration become a marked feature of municipal supplies. Even then, the number of applications was small and pertained chiefly to stored surface waters subject to tastes and odors from algae growths.
