AIR VALVE UPGRADE ON WASTEWATER TREATMENT PIPELINE

The Lac La Biche utilities department had pipeline efficiency problems in several sections of their wastewater collection and treatment system. These lines were operating at reduced capacity due to accumulated air and gas inside the pipes, forcing lift station pumps to work harder to achieve minimum flow rates.

Watch this YouTube video to see how air affects pipe capacity and pump load.

Installing combination air release valves on these pipelines was the correct course of action. The utility selected the A.R.I. D-020 Combination Air Valve for Wastewater. They installed the valves onto the pipe using a tapping sleeve (to add a flanged opening into the pipe) and isolation valve (to close the hole in the pipe during air valve maintenance).

This is a common installation method in Canada to add A.R.I. air valves to an existing pipeline.

A.R.I. designs and manufacturers air valves that work reliably to ensure the efficiency of water supply and wastewater disposal systems in both urban and rural environments. Use ARI air valves in your next water pipeline or pump station project.

A.R.I. is represented in Canada by Martech. Use the “LEARN MORE” form on this page to ask Martech for air valve selection and placement advise. We will connect with you and help determine which air valve will fit with your design.

HOW DOES THE D020 AIR VALVE ACTION WORK?

The D-020 Combination Air Valve combines an air & vacuum orifice and an air release orifice in a single body. The valve is specially designed to operate with liquids carrying solid particles such as wastewater and effluents.

1) The D020 combination air valve discharges air when the pipeline is filling and releases accumulated gasses while the line is under pressure and operating.

2) Filled pipeline raises float and closes air release mechanism.

3) Valve float lowers to admit air into draining pipeline.

4) The valve’s sealing mechanism never comes into contact with dirt and debris borne by the water. This reliable design prevents damage in the valve and ensures long-term operation.
