These parts fit and interchange with the Nelsen Corporation's "Terminator" Aeration Systems. The image to the right is an aeration system that acts as an acid neutralizer as well. 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. They need to be installed after the well pump but before the pressure tank. Venturi-Aerators are limited to approximately 37kg of oxygen transfer per hour by a single [six inch] unit. Water can therefore be drawn from anywhere and at any depth of the tank or lagoon, and can be discharges anywhere and at any depth. The water passage closest to the check valve (2) contains built-in convergent and divergent cones forming a venturi. Two Popular Ways to Eliminate Odor from Well Water: Chlorination/Peroxide Injection or Aeration Foul odors are a common problem in well water systems. It also oxidises sulphur containing molecules such as hydrogen sulphide and mercaptans for effective odour and corrosion control, as well as reducing the size of organic solids. PWP Budget Air Mix Assembly. While typically used for ozone, air, or oxygen injection, venturi injectors are also compatible with liquids. They are also able to perform these maintenance tasks in relative safety on lagoon banks. As the water flows into the aeration tank, the water causes a venturi flow of air through the inlet tube. 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]. To deliver more oxygen [by atmospheric aspiration], multiple units must be used. The vent valve on top of the aeration tank vents off excess air. Pump clearances can be adjusted in minutes. When you need to inject air, oxygen, or ozone into water, a venturi injector is one of the best methods to use. The types of information needed is as follows:-. Air (oxygen) enters the Water Stream AFTER the Water travels through the Pump. Water aeration occurs when air is sucked in at the restriction of a venturi and enters the water stream as bubbles, increasing the dissolved oxygen as the water as it exists the Venturi. Installation costs will therefore be lower, there will be no need for expensive floating walkways, tethering systems or overhead cranes for retrieval. The air and water then passes into the “mixing and oxidation zone” where the wastewater and air are mixed under pressure. Honeywell/Braukmann Air Vent, 1/8".
