What Is Venturi Aeration? Inside Water Treatment’s Game-Changer

In the world of wastewater management, water treatment and industrial processing, venturi aeration is an incredibly impactful innovation that has made rectifying problems an easy task. The theory behind this aeration process was first discovered by the Italian physicist Giovanni Battista Venturi and has gone on to vastly improve the efficiency, simplicity and maintenance requirements of water and wastewater systems.

In water treatment and wastewater plants, the objective is to keep the water as healthy as possible in the face of organic matter that can render it unusable. Venturi aeration is a method of introducing oxygen into the water using a specialised tube (called a Venturi tube) to support the microorganisms that break down organic matter.

A venturi aerator pump is distinguished by its specialised Venturi tube, a device whose tapered design with a narrow throat and wider inlet and outlet sections decreases the pressure of the liquid flow. Modern Venturi aerator pumps have an easily-adjustable Venturi tube that can be modified to control the amount of oxygen that’s introduced into the liquid flow.

This process is crucial for managing a water or wastewater pumping system. By installing a Venturi tube at the location where the liquid flow is more pressurised, the liquid will flow through and increase in velocity as it passes through the narrow midsection. In the laws of physics, when the velocity of a fluid increases, the pressure decreases, and this causes a suction effect in the midsection of the Venturi tube that helps to stabilise the pump system as a whole.

Multiple Venturi aerator pumps are available that are designed for different amounts of solids present in the liquid flow. US manufacturer Gorman-Rupp has the Super-T Series, Ultra V or U Series pumps for this application, which are paired with their Echostorm Venturi tube. The surface-mounted assembly of these pumps makes it simple to retrofit additional equipment such as ground-level lagoons and tanks.
