Two Venturi-Aeration systems aspiration Oxygen into a wet well. Vent Tubing Connector for Honeywell Air Vent. A Venturi-Aerator is a device used to mix and aerate tanks, ponds and lagoons. from industrial waste streams and groundwater, Stripping CO2 to raise pH, allowing for nitrification (pH >6.8) to begin, The size of the tank or lagoon [Length x Width x Depth], The amount of inflow into the tank or lagoon, The type of operation needing the treatment [Sewage Treatment Plant, Food Process plant etc], The goal of the treatment [increase dissolved oxygen, reduce BOD or COD, increase pH levels, destratification, oxidation of the fluid, odour reduction etc]. How To Select The Right Internal Gear Pump? Alternatively, if oxygen demands have peaks [for example, the “Vintage” period at wineries], pure oxygen can be aspirated from a stationary source [like a liquid oxygen plant or liquid oxygen tanker]. It uses Bernoulli’s principle, whereby a low pressure area is created by an accelerated fluid. When you need to inject air, oxygen, or ozone into water, a venturi injector is one of the best methods to use. All mechanical equipment will need some kind of maintenance or repair. With the aerated water entering the well at a lower level than with traditional spray heads, the entire well is more thoroughly aerated. The Waterite Micronizer consists of a high impact Celcon® plastic body containing two water passages. On-going monitoring and maintenance is also much easier, simpler and safer with a Venturi-Aerator. Its pretty simple, and works very well. A pressure vessel or vessel at atmospheric pressure downstream of the aeration system serves for removing entrained air bubbles and degassing of the water.For a venturi based air injection a few design rules need to be considered: The venturi and static mixer should be … The turbulent mixing facilitates the removal of substances with weak Henry’s constants such as CO2 and VOC’s. As water is forced through the venturi while the pressure tank is filling, air is sucked into the water line. Suction and discharge positioned to suit. Floating type or submersible type systems will not get much attention [unless they break down], because of the difficulty in accessing them. The image to the right is an aeration system that acts as an acid neutralizer as well. Waterite Air Injector, 1"--3/8 to 16 gpm. Water Flow Through the Pump is NOT Affected if the Air Volume is Metered. Because of the nature of the system [using a self-priming pump], mixing and destratification is controlled by the positioning of the suction and discharge of the pump. The nut on the left provides an adjustment. Contact Us. Air (oxygen) enters the Water Stream AFTER the Water travels through the Pump. While typically used for ozone, air, or oxygen injection, venturi injectors are also compatible with liquids. These parts fit and interchange with the Nelsen Corporation's "Terminator" Aeration Systems. In a spray aeration system, water enters through the top of the unit and emerges through spray heads in a fine mist. Venturi wastewater aeration delivers dissolved air/oxygen from the bottom up for complete aeration. Waterite Venturi Air Injector.
