Venturi Aeration Systems

Posted March 31st, 2020

  Simple, Inexpensive Aeration System for Treatment of Iron and Hydrogen Sulfide

Pure Water Products offers state-of-the-art AerMax systems with electric air pumps for treatment of iron, manganese and hydrogen sulfide, and we provide a good variety of parts for these systems on our main website. We also offer “single tank aerators,” which are filter that draw in air to treat contaminants during their regeneration process. We no longer sell the systems shown on this page, but the page is being left up for information.  If you need a part for the aeration system shown, call and we can normally supply it.

These parts fit and interchange with the Nelsen Corporation’s “Terminator” Aeration Systems. Please call for information and pricing on complete Terminator units or for any of the parts shown on this page.

In the passive venturi aeration system pictured above, when the well pump is running, water from the well passes through the venturi valve which draws air into the water line. An aeration tank which follows the well’s regular pressure tank provides contact time and mixing space so that the air can oxidize the iron, manganese, or hydrogen sulfide for removal by a filter. (The filter is not shown and is not included in this product. We provide many excellent filters for this purpose on our main website.) The vent valve on top of the aeration tank vents off excess air.
