Cochrane pH Adjustment Filtration
Cochrane and Newterra provide pH Adjustment systems in both Filtration (passive) and Chemical Injection (active) configurations.
In the Filtration (passive) systems, feed water enters the vessel through an inlet valve and is sprayed out over the calcium carbonate media. The water then flows down through the media. The acidic water slowly dissolves the calcium carbonate which increases the pH.
The result is an effective way to increase pH without the use of chemicals. The increased pH water enters the distributor system at the bottom of the vessel and travels upward via the center riser tube where it is then piped out of the vessel.
